Abstract (sommario):

Indonesia sebagai salah satu negara yang memiliki pulau pulau besar dan kecil berada di daerah tropis, menerima radiasi matahari paling banyak serta dipengaruhi oleh berbagai fenomena atmosfer menyebabkan wilayah ini rentan terhadap variabilitas dan perubahan iklim. Iklim di Indonesia tidak akan selalu berjalan secara normal setiap tahunnya, ada suatu saat terjadi penurunan curah hujan namun di saat yang lain terjadi curah hujan yang tinggi sehingga menyebabkan banjir. Sebagian masyarakat beranggapan bahwa terjadinya banjir dan kemarau panjang diakibatkan oleh dosa-dosa manusia, diantaranya adanya berjudi, membunuh, merampok dll. Hal ini memerlukan Eksplanasi Ilmiah agar dapat memberikan jawaban terhadap pertanyaan-pertanyaan tentang adanya penyebab penurunan curah hujan atau terjadi nya kekeringan dan terjadinya curah hujan atau bencana banjir di Indonesia. Sesuatu dieksplanasi secara ilmiah jika memenuhi dua syarat, yaitu syarat relevan eksplantori dan syarat testabilitas, syarat pertama eksplanasi ilmiah dapat terpenuhi dengan menggunakan penjelasan dan pengertian El Nino dan La Nina yang merupakan salah satu bentuk penyimpangan iklim di Samudera Pasifik yang ditandai dengan kenaikan suhu permukaan laut di daerah katulistiwa bagian tengah dan timur, Sedangkan La Nina sebaliknya dari El Nino. Dengan penjelasan dan pengertian El Nino dan La Nina yang memenuhi syarat kedua eksplanasi ilmiah yaitu dampak El Nino adalah terjadinya kekeringan dan dampak El Nina adalah terjadinya musim hujan. Hal ini sesuai dengan hakikat pembuktian keilmuan adalah kepercayaan bahwa suatu pernyataan dan pengertian mempunyai peluang besar untuk terbukti ataubenar.

Abstract (sommario):

Paddy and maize are two important food crops in Indonesia and mainly produced in Java Island. This research aimed to know the impact of El Nino and La Nina on paddy and maize farmer’s supply in Java. Cross sectional data from four provinces in Java was combined with time series data during 1987-2006. Paddy supply was estimated using log model, while maize supply used autoregressive model; each was estimated using two types of regression function. First, it included dummy variable of El Nino and La Nina to know their influence into paddy and maize supply. Second, Southern Oscillation Index was used to analyze the supply changing when El Nino or La Nina occur. The result showed that El Nino and La Nina did not influence paddy supply, while La Nina influenced maize supply in Java. Maize supply increased when La Nina occurred.

Abstract (sommario):

Fenomena badai siklon adalah salah satu bencana hidrometeorologi yang paling merusak di Bumi. Siklon bisa terjadi di kawasan yang dipengaruhi aktivitas El Nino (La Nina). Siklon tropis maupun El Nino dapat menyebabkan kondisi cuaca atau iklim ekstrim di daerah tropis. Pada kajian ini, dilakukan kajian mengenai dampak fenomena El Nino (La Nina) terhadap besar kecilnya badai siklon (intensitas siklon) di sekitar wilayah Indonesia. Besar kecilnya badai siklon tersebut diklasifikasikan dengan menggunakan Skala Saffir-Simpson. Selain intensitas, dikaji pula hubungan El Nino (La Nina) dengan masa hidup dan frekuensi kemunculan fenomena siklon di sekitar wilayah Indonesia. Penelitian ini akan membandingkan data siklon pada tahun ketika terjadi peristiwa El Nino (La Nina) dengan data siklon pada tahun ketika tidak terjadi peristiwa El Nino (La Nina). Dalam kajian ini, digunakan data siklon selama 10 tahun (2007-2017) dari situs JAXA (Japan Aerospace Exploration Agency). Selain itu, digunakan juga data indeks El Nino dalam Nino 3.4 sebagai data aktivitas ENSO. Metode yang digunakan dalam penelitian ini menggunakan metode statistik. Dari hasil analisis tersebut, secara umum diperoleh bahwa El Nino (La Nina) memiliki pengaruh positif yang signifikan terhadap intensitas dan masa hidup siklon di sekitar wilayah Indonesia. Secara khusus, El Nino (La Nina) memiliki pengaruh positif yang signifikan terhadap intensitas dan masa hidup siklon di wilayah utara ekuator. Sementara itu, di selatan ekuator tidak menunjukan korelasi yang signifikan. Pengaruh El Nino (La Nina) terhadap frekuensi siklon belum dapat terlihat dengan jelas pada penelitian ini sehingga diperlukan penelitian lebih lanjut mengenai hal ini.

Abstract (sommario):

Climate anomaly phenomena are increasing in frequency and duration along with the occurance of global warming phenomena. El Nino and La Nina climate anomalies have a direct impact on agriculture. This study aims to analyze the occurrence of extreme climate phenomena El Nino and La Nina in 2012-2022 in Indonesia and their impact on rainfall in South Sumatera Province which is one of the centers of oil palm plantations. The research was conducted by identifying sea surface temperature (SST) anomalies in the Pacific Ocean and classifying them into El Nino and La Nina strength levels or normal conditions. Based on the sea surface temperature anomaly, it is known that Indonesia experienced strong El Nino events in 2014-2015 and weak El Nino in 2019. El Nino causes a prolonged dry season and decreases the amount of rainfall. The La Nina phenomenon occurs in 2020-2022 with weak to moderate strength. La Nina causes a prolonged rainy season and an increase in the amount of rainfall. Normal conditions occurred in 2013, 2016, 2017 and 2018 which were marked by sst anomalies of not more than +0.5°C and -0.5 °C. During normal conditions, South Sumatra Province has an annual rainfall of 2,500 mm, rainfall is evenly distributed throughout the year, and dry months are less than 3 months that suitable for oil palm cultivation. In the last 10 years, Indonesia has experienced the El Nino and La Nina climate anomalies with increasing frequency, duration, and level of strength.

Abstract (sommario):

El Nino and La Nina events have an impact on the Indian monsoon in terms of less rainfall than average and more rainfall in La Nina years. El-Nino events are more likely to see rainfall variability during the monsoon and depressions over the Bay of Bengal (July-August). ENSO is a disruption in ocean surface temperatures and atmospheric circulation over the Pacific Ocean leading to wide spread changes in rainfall/precipitation regimes around the world. El Nino years' effects on crop production in India as a result of lower rainfall during the south-west monsoon. In the kharif season (June to September), crops suffer from moisture and have lower yields in El-Nino years, but the opposite in La-Nina years. The El Nino is associate with the possibility of drought like situation at many occasions and La Nina is the opposite of El-Nino events.

Abstract (sommario):

The study aimed to determine the years of events El Nino and La Nina, analyze the effects of El Nino and La Nina events on water balance, and determine the available growing periods in Waeapo areas under various rainfall conditions. Climate data analysis was carried out with the following stages: a) generation of rainfall data; b) analysis of extreme rainfall of El Nino and La Nina; c) calculation of land water balance using the Thornthwaite-Mather method; and d) determination of available growing period under various rainfall conditions. The results showed that in the last 30 years in the Waeapo area, there were eight times of a phenomenon of extreme dry rainfall (El-Nino), with an average intensity of once every three years. The phenomenon of extreme wet rainfall (La-Nina) occurred six times with an average intensity of once every five years. Based on the calculation of land water balance, during El-Nino rainfall conditions, there was an annual groundwater deficit of 403 mm or 172% of normal conditions, whereas during La-Nina rainfall conditions there was a surplus of annual groundwater of 775 mm or 222% of normal conditions. When an El-Nino phenomenon occurred, the available growing period was only five months (January to May), and when the La-Nina phenomenon occurred, the growing period was available throughout the year (12 months). Keywords: El Nino, La Nina, land water balance, available growing period, Buru Island ABSTRAK Penelitian bertujuan untuk menentukan tahun-tahun kejadian El Nino dan La Nina, menganalisis dampak kejadian El Nino dan La Nina terhadap neraca air lahan, dan menetapkan periode tumbuh tersedia di daerah Waeapo pada berbagai kondisi curah hujan.

Abstract (sommario):

ENSO (El Nino Southern Oscillation) merupakan gejala penyimpangan suhu permukaan laut di Samudera Pasifik bagian timur dari kondisi normal. Penelitian ini menganalisis dampak dari perbedaan posisi pusat ENSO terhadap curah hujan di Indonesia. Posisi pusat ENSO ditentukan berdasarkan indeks terbesar dari empat indeks Nino selama tahun 1982-2016. Posisi pusat ENSO didefinisikan jauh, menengah dan dekat dari Indonesia ketika indek Nino yang terbesar berturut-turut adalah Nino 1+2, Nino 3 dan Nino 3,4, serta Nino 4. Intensitas curah hujan di setiap posisi ENSO diamati menggunakan data Global Precipitation Climatology Centre (GPCC). Rata-rata curah hujan bulanan pada saat pusat El Nino jauh dari Indonesia lebih tinggi di kawasan Indonesia bagian timur. Selain itu, selama pusat El Nino jauh dari Indonesia, kondisi yang lebih kering teramati di sebagian besar wilayah Indonesia bagian barat dan tengah. Pada sisi lain, rata-rata intensitas curah hujan bulanan pada saat La Nina menengah lebih tinggi dibandingkan La Nina jauh. Perbedaan intensitas curah hujan dari setiap posisi ENSO ini selaras dengan perbedaan pergerakan udara ke atas yang tergambar dari nilai omega dari data reanalisis NCEP dan NCAR. Dengan demikian, posisi ENSO mempengaruhi curah hujan di Indonesia walaupun dampaknya tidak seragam. ENSO (El Nino Southern Oscillation) is a periodic fluctuation in sea surface temperature and other meteorological parameters across the equatorial Pacific Ocean. This study investigates the impact of ENSO's central position on rainfall pattern in Indonesia. The location of the ENSO was determined by the largest index of four Nino indexes during 1982-2016 and itis defined far, medium and close to Indonesia when the largest Nino indexes are Nino 1+2, Nino 3 and Nino 3.4, and Nino 4. Rainfall intensity at each ENSO position was observed using Global Precipitation Climatology Centre (GPCC) data. Average monthly rainfall when the El Nino central position is far from Indonesia is higher in the eastern part of Indonesia. In addition, when the El Nino central position is far from Indonesia, drier conditions are observed in large parts of western and central Indonesia. On the other hand, the average intensity of monthly rainfall during medium position of La Nina is higher than that for La Nina cases with the central position being far from Indonesia. The difference in rainfall intensity from each ENSO position coincides with the difference in upward air movement which is reflected by the omega values from the NCEP and NCAR. reanalysis data. Thus, the position of ENSO influences rainfall in Indonesia even though the impact is not uniform.

Abstract (sommario):

El Ni??o-Southern Oscillation (ENSO) is the most important coupled ocean-atmospheric phenomenon to cause global climate variability on interannual time scales. Efforts to understand recent, apparently anomalous ENSO behaviour are hampered by the lack of long, high-quality climate records. While instrumental data generally covers the past 150 years, record length is insufficient for the assessment of past changes in the frequency, magnitude, and duration of ENSO. Here, multiproxy networks of high-resolution tree-ring, coral, ice and documentary records derived from eastern and western Pacific ENSO ???centres of action??? are analysed (A.D. 1525-2002). Considerable improvements in ENSO reconstruction are achieved from expanding the use of records from the western Pacific. In particular, ~500 years of a continuous 3,722 year ENSO sensitive tree-ring record from New Zealand is introduced. Although extreme ENSO events are seen throughout a 478-year discrete event analysis, 43% of extreme, 20% of very strong and 28% of all protracted ENSO events occur within the 20th century. Principal component analysis was used to extend instrumental records of the Southern Oscillation Index (SOI) Ni??o 3.4 Sea Surface Temperature (Ni??o 3.4 SST) and a newly developed coupled ocean-atmospheric ENSO index (CEI) by 347 years. Significantly, of the three indices reconstructed here, CEI reconstructions were largely found to be the best predictors of ENSO. The results suggest that ENSO may be more effectively characterised using a coupled ocean-atmosphere index, particularly for December-May periods. Compared to the pre-instrumental period, the late 19th and early 20th centuries indicate a clear trend toward increased ENSO variability over the past 150 years. Significantly, spectral analysis of reconstructed indices reveals a marked change in the frequency and intensity of ENSO beginning ~A.D. 1850, coinciding with the end of the Little Ice Age and the boom in global industrialisation. This suggests that ENSO may operate differently under natural (pre-industrial) and anthropogenically influenced background states. This study asserts that recent ENSO variability appears anomalous in the context of the past five centuries. Given the considerable socio-economic impacts of ENSO events, future investigation into the implications an increasingly anthropogenically-warmed world may have on ENSO is vital.

Abstract (sommario):

Determination of safe yield of a water source is a basic aspect of water supply planning. In this report, the safe yield is defined as the maximum constant release from a reservoir that is possible during a selected drought period. The yield depends on drought magnitude and duration controlled by nature and ability to manipulate the releases through man made controls in the form of impoundment structures and regulations. A water supply system with two reservoirs in series and one in parallel in Spotsylvania Countyâ the Hunting Run Reservoir, the Motts Run Reservoir (in series), and the Ni River Reservoir is considered to demonstrate the yield calculations. When several reservoirs are considered, the critical periods (defined as the period from full storage to empty condition) may not coincide and the system must be analyzed for the binding critical duration. A zero-one linear integer programming formulation is proposed to compute the system yield. The formulation accommodates the various storage and river flow dependent instream flow requirements. It is found that the water treatment plant capacity, instream flow requirements, and flows themselves limit the yield. Inflows to the reservoir are very important factor in determination of safe yield for any system of reservoirs. Changes in the precipitation hence inflows may cause a significant effect on the operation of reservoir. El Nino and La Nina phenomena, which occur due to changes in the atmospheric condition over the equatorial Pacific region, are found to affect the global climate in different studies. To examine the changes in the precipitation / streamflows due to El Nino and La Nina events on the safe yield, studies are done on the streamflows in the study area and four regions across the world during El Nino and LA Nina events. Lag correlation studies and descriptive analysis of the streamflows in the study region in Northern Virginia fail to show any pattern in the streamflow changes due to El Nino and La Nina events, based on the available data. However, this observation is not conclusive and further research if needed.

Abstract (sommario):

The effects El Nino and La Nina have on corn futures prices is analyzed through the lens of the Southern Oscillation Index (SOI), a measure that indicates El Nino or La Nina weather patterns. Reliable data from 1959 - 2014 is analyzed in both monthly and yearly frequencies. As well as running the data against the SOI, binary indicators for either El Nino or La Nina are used as well. Typically, El Nino is consistent with cooler, wetter over much of North America and La Nina is consistent with hotter, drier weather. Both of these weather patterns will either increase or decrease corn production, which in turn affects corn futures prices.

Abstract (sommario):

Typically, multi-model ensemble studies show mixed responses of El Nino Southern Oscillation (ENSO) under global warming, so it is currently unknown how, or even if, global warming will impact ENSO and its teleconnections. ENSO is governed by various ocean-atmosphere interactions in the equatorial Pacific, which provide either positive amplifying or negative damping feedbacks and are not always accurate in models. This results in uncertainty in projected ENSO responses. In a flux adjusted HadCM3 perturbed physics ensemble, the Bjerknes' stability index (BJ index), a measure of ENSO stability, has been used to analyse the strength of ENSO feedbacks and their response under the SRES A1B warming scenario with respect to mean climate conditions. Despite mean sea surface temperature biases being minimised by flux adjustment, the important dominant feedbacks, namely the latent heat flux feedback, shortwave flux feedback, the thermocline feedback and the zonal advective feedback are found to be too weak in the ensemble. Common model biases cause weak ocean-atmosphere interactions such as a weak response of ocean currents to wind stress anomalies, a weak thermocline slope response to wind stress anomalies and weak thermodynamic dampings. These biases are linked to overly strong zonal surface ocean currents and convective response biases. Under global warming, a large increase in thermodynamic damping, caused by increasing shortwave damping, is found. This increase is linked to a strong convective response and overrides other feedback responses, resulting in a weakening BJ index in contrast to increasing ENSO amplitude. Positive feedback responses are also found but counteract each other, so have relatively little impact on total ENSO stability. Results here show that common model biases, such as the cold tongue bias, are linked to persistent ENSO feedback biases pointing to areas of improvement in future models. Results also suggest that caution must be exercised when using the BJ index to assess ENSO, as the BJ index is not always representative of ENSO amplitude. This may be caused by non-linearities in ENSO feedbacks which are not accounted for by the linear approximations used in the BJ index, or by ENSO feedbacks not being directly comparable in magnitude, as assumed by the BJ index calculation.

The daily precipitation data referring to 134 localities in the State of Minas Gerais, supplied by the Agência Nacional de Águas (ANA), were analyzed in order to characterize the rainy period (RP), as well as the event and duration of the dry spells occurring over the climatic events El Niño (EN) and La Niña (LN). At first, the beginning of the rainy periods (BRP) and the precipitation amount of the rainy period were analyzed, respectively based on the averages and normalized standard deviations of three annual series: El Niño, La Niña and neutral years. The influence of these phenomena on each 15-day period over the months from November to February were analyzed, by using the average and the standardized precipitation rate, as well as the behavior of each RP based on precipitation anomalies. For both analyses, seven stations were chosen according to the climatically homogeneous areas in Minas Gerais. Then, the frequency of dry spells was determined to intervals with four durations in these three series, and the dry spell was defined as a period with at least three dry consecutive days (precipitation ≤ 1 mm) during the rainy period. The method of Regression Analysis was used to relate the duration of the rainy period (RPD) and, or, BRP with the dry spells lasting from three to six days (A) and from seven to ten days (B), as well as the BRP and the total precipitation amount during RP with the dry spells classified as classes A and B, respectively. The results obtained for the influence of the EN and LN phenomena were georeferrenced by the interpolation method that materialized them into thematic maps generated by the Geographic Information System (GIS). The thematic maps were obtained, by involving of Minas Gerais State Digital Elevation Model (DEM) with the classification concerning to the total precipitation and RPD with the average frequencies of the dry spells. A characteristic of La Niña is to cause rains below the average on an extensive part of the State, as well as on half-Northeastern over events El Niño, and rains above the average on half- Southwestern Minas Gerais. The dry spells caused by LN on the North-Northeastern part of the State are due to the periods lasting more than 15 days, whereas on the South-Southwestern are due to the dry spells lasting from three to six days. Similarly, the dry spells on North-Northeastern of Minas Gerais during El Niño events, and the rains above the average on the half-Southwestern of the State cause an influence of the dry spells lasting three to six days.
Dados diários de precipitação de 134 localidades do estado de Minas Gerais, fornecidos pela Agência Nacional de Águas (ANA), foram analisados com o intuito de caracterizar o período chuvoso (PC) e o comportamento na ocorrência e duração dos veranicos em anos de eventos climáticos El Niño (EN) e La Niña (LN). Inicialmente, foram classificados o início dos períodos chuvosos (IPC) e a quantidade pluviométrica do PC, baseados, respectivamente, nas médias e desviospadrão normalizados de três séries, sendo elas: anos de El Niño, anos de La Niña e anos neutros. Conjuntamente, foram analisadas a influência destes fenômenos nas quinzenas dos meses de novembro a fevereiro, com a utilização da média e do índice padronizado de precipitação e o comportamento de cada PC baseando-se nas anomalias de precipitação. Ambas análises, para sete estações distribuídas por regiões climaticamente homogêneas de Minas Gerais. Em seguida, determinou-se a freqüência de ocorrência de veranicos para quatro intervalos de duração nas três séries, sendo definido, como veranico, o período de pelo menos três dias secos (precipitação ≤ 1 mm) consecutivos durante o período chuvoso. Foi utilizado o método de análise de regressão, para relacionar a duração do período chuvoso (DPC) e, ou, IPC com os veranicos com duração de três a seis dias (A) e de sete a dez dias (B), e o IPC, total pluviométrico durante o PC com os veranicos de classes A e B. Os resultados referentes à influência dos fenômenos EN e LN foram geoespacializados, utilizando-se método de interpolação que os materializou em forma de mapas gerados por intermédio de um Sistema de Informações Geográficas (SIG). Foram efetuadas sobreposições de temas, envolvendo o relevo do Estado com a classificação referente ao total pluviométrico e da DPC com as freqüências médias de veranicos. A La Niña possui uma característica marcante de ocasionar chuvas abaixo da média em grande parte do Estado, da mesma forma para a metade nordeste em episódios do El Niño e chuvas acima da média na metade sudoeste de Minas Gerais. As estiagens ocasionadas pela LN, no Norte- Nordeste do Estado, são devidas a períodos superiores a 15 dias de duração e no sul-sudoeste aos veranicos com duração de três a seis dias. Da mesma forma, ocorre para as estiagens no Norte-Nordeste de Minas Gerais, durante eventos El Niño e as chuvas acima da média na metade sudoeste ocasionam uma influência, somente, por parte dos veranicos com duração de três a seis dias.

Abstract (sommario):

Ekstremalių ir natūralių klimatinių reiškinių intensyvumo pokyčiai tampa vis aktualesnė šių dienų aplinkosaugos problema. Dėl nepalankių globalaus klimato pokyčių pastebima vis didesnė žala žmogui ir jo gyvenamajai aplinkai. El Nino ir La Nina yra kompleksinis klimato kaitos reiškinys, sukeliantis vandenyno temperatūros kaitą, intensyviausiai pasireiškiantis Ramiajame vandenyne, ekvatorinėje srityje. Yra atlikta daugybė tyrimų, išaiškinančių El Nino ir La Nina ciklo daromą įtaką pasaulio klimatui. NAO (North Atlantic Oscillation) yra vienas iš svarbiausių Lietuvos klimatą lemiančių veiksnių. Per pastaruosius dešimtmečius pastebimas vis didesnis El Nino ir La Nina reiškinių poveikis Lietuvos klimatiniams reiškiniams ir metų sezoniškumui, todėl atitinkamai ir upių hidrologiniam režimui. Darbe atliekama tiriamųjų upių Bartuvos, Merkio ir Šušvės hidrologinių (nuotėkio) ir klimatinių (kritulių ir oro temperatūros) rodiklių statistinė analizė. Nustatomi tiriamųjų rodiklių tarpusavio ryšiai ir nustatomas El Nino ir La Nina reiškinių poveikis tiriamiesiems rodikliams. Tyrimais nustatomas El Nino ir La Nina poveikio stiprumas Lietuvai ir tiriamosioms upėms ir įtaka didžiausių vandeningumų metams, kritulių kiekiui ir temperatūrai baseinuose.

Abstract (sommario):

Abstract Atypical weather conditions are known to occur for extended periods of time that either may or may not coincide with El Nino and La Nina events in the Pacific Ocean. Anomalies that increase clouds influence the reliability of both renewable energy and building environmental-control systems. Backup equipment on non-grid solar power systems may run out of capacity for such items as communications electronics, flood-warning stream gages, refrigerators, and small village power systems in remote regions. This paper provides 1×1-degree resolution global maps that identify those regions which experienced large abnormal solar energy during a 10-year period. A source is identified where specific values for maximum year-to-year variability can be obtained in regions where ground-site measurements do not exist.
