Resumen
Abstract. Much research is needed regarding the two long-term warming targets of the 2015 Paris Agreement, i.e., 1.5 and 2 ∘C above pre-industrial levels, especially from a regional perspective. The East Asian summer monsoon (EASM) intensity change and associated precipitation change under both warming targets are explored in this study. The multimodel ensemble mean projections by 19 CMIP5 models show small increases in EASM intensity and general increases in summer precipitation at 1.5 and 2 ∘C warming, but with large multimodel standard deviations. Thus, a novel multimodel ensemble pattern regression (EPR) method is applied to give more reliable projections based on the concept of emergent constraints, which is effective at tightening the range of multimodel diversity and harmonize the changes of different variables over the EASM region. Future changes projected by using the EPR method suggest decreased precipitation over the Meiyu belt and increased precipitation over the high latitudes of East Asia and Central China, together with a considerable weakening of EASM intensity. Furthermore, reduced precipitation appears over 30–40∘ N of East Asia in June and over the Meiyu belt in July, with enhanced precipitation at their north and south sides. These changes in early summer are attributed to a southeastward retreat of the western North Pacific subtropical high (WNPSH) and a southward shift of the East Asian subtropical jet (EASJ), which weaken the moisture transport via southerly wind at low levels and alter vertical motions over the EASM region. In August, precipitation would increase over the high latitudes of East Asia with more moisture from the wetter area over the ocean in the east and decrease over Japan with westward extension of WNPSH. These monthly precipitation changes would finally contribute to a tripolar pattern of EASM precipitation change at 1.5 and 2 ∘C warming. Corrected EASM intensity exhibits a slight difference between 1.5 and 2 ∘C, but a pronounced moisture increase during extra 0.5 ∘C leads to enhanced EASM precipitation over large areas in East Asia at 2 ∘C warming.

Resumen
By using an objective identification and tracking algorithm of the cyclone, the statistics of midlatitude cyclone activity in East Asia during summer for the period 1979–2013 were analyzed. The impact of the midlatitude summer cyclone anomalies in East Asia on the decadal mode of East Asian summer monsoon (EASM) was investigated and possible mechanisms were proposed. The possible reasons for the anomalous cyclone activity from the perspective of land surface thermal forcing were also explored. Results indicate that the midlatitude summer cyclone activity over East Asia exhibits decadal changes in the period of 1979–2013 and is significantly weakened after early 1990s. Further analysis indicates that there is a close relationship between the midlatitude summer cyclone activity over East Asia and the decadal variation of EASM; when the midlatitude summer cyclone activity over East Asia is strong (weak), EASM tends to be intensified (weakened), and the weak cyclone activity after 1993 generally coincides with the decadal weakening of EASM. Moreover, there is a close linkage between the weakening of cyclonic activity after the early 1990s and the nonuniform surface warming of the Eurasian continent. Significant warming to the west of Mongolia tends to weaken the north–south temperature gradient and the atmospheric baroclinicity to its south and eventually can lead to weakening of the midlatitude cyclone activity over East Asia.

Resumen
Abstract. Tropospheric ozone in East Asia is influenced by the transport of ozone from foreign regions around the world. However, the magnitudes and variations in such influences remain unclear. This study was performed to investigate the influences using a global chemical transport model, GEOS-Chem, through the tagged ozone and emission perturbation simulations. The results show that foreign ozone is transported to East Asia (20–60∘ N, 95–150∘ E) mainly through the middle and upper troposphere. In East Asia, the influence of foreign ozone increases rapidly with altitude. In the middle and upper troposphere, the regional mean concentrations of foreign ozone range from 32 to 65 ppbv, being 0.8–4.8 times higher than its native counterpart (11–18 ppbv). Annually, ∼60 % of foreign ozone in the East Asian middle and upper troposphere comes from North America (5–13 ppbv) and Europe (5–7 ppbv), as well as from foreign oceanic regions (9–21 ppbv). Over the East Asian tropospheric columns, foreign ozone appears most in spring when ozone concentrations in the foreign regions are high and the westerlies are strong and least in summer when the South Asian High blocks eastward foreign ozone from reaching East Asia south of 35∘ N. At the East Asian surface, the annual mean of foreign ozone concentrations is ∼22.2 ppbv, which is comparable to its native counterpart of ∼20.4 ppbv. In the meantime, the annual mean of anthropogenic ozone concentrations from foreign regions is ∼4.7 ppbv, half of which comes from North America (1.3 ppbv) and Europe (1.0 ppbv). Seasonally, foreign ozone concentrations at the East Asian surface are highest in winter (27.1 ppbv) and lowest in summer (16.5 ppbv). This strong seasonality is largely modulated by the East Asian monsoon (EAM) via its influence on vertical motion. The large-scale subsidence prevailing during the East Asian winter monsoon (EAWM) favours the downdraft of foreign ozone to the surface, while widespread convection in the East Asian summer monsoon (EASM) blocks such transport. Interannually, the variation in foreign ozone at the East Asian surface is found to be closely related to the intensity of the EAM. Specifically, the stronger the EAWM is in a winter, the more ozone from North America and Europe reaches the East Asian surface because of the stronger subsidence behind the East Asian trough. In summer, ozone from South and South-east Asia is reduced in strong EASM years due to weakened south-westerly monsoon winds. This study suggests substantial foreign influences on ozone at the East Asian surface and in its tropospheric columns. It also underscores the importance of the EAM in the seasonal and interannual variations in foreign influences on surface ozone in East Asia.

Resumen
This paper examines the debate on the East Asian model of economic development in light of the different approaches undertaken by different groups of countries (economies) in Northeast Asia and Southeast Asia. The common strengths and weaknesses shared by the East Asian countries (economies) have helped to reinforce the misconception that there is a single East Asian model of economic development. There are, however, significant differences in economic structures as well as development experiences among the East Asian economies, especially between the economic development paradigms of Southeast Asia and Northeast Asia. Nonetheless, one single common thread underlies the differences in development strategies and experiences among the East Asian economies—the role of the government. The governments of East Asia have recognized the limitations of markets (or market failures) in the allocation of scarce resources in the economy, and have used government interventions to promote economic development. The recent Asian crisis hardly signifies the end of the so-called East Asian model of economic development.

Resumen
Abstract The thermal and mechanical effects of the regional orography have long been recognized as the two most important factors driving the East Asian summer monsoon (EASM). The Southeast Asian low-latitude highlands (SEALLH) are a warmer and wetter highland region adjacent to the southeastern margin of the Tibetan Plateau. However, the importance of the individual contributions of the thermal and mechanical effects of the SEALLH to the EASM is still unclear. Results of numerical experiments show that the thermal effect of the SEALLH contribute to the precipitation and upper-tropospheric circulation of the EASM by roughly the same magnitude as the mechanical effect of the SEALLH, when its original height is reduced by 50%. The thermal effect of the SEALLH influences the EASM by exciting an East Asia–Pacific-like teleconnection, whereas the mechanical effect of the SEALLH impacts the EASM by exciting an equivalent barotropic Bay of Bengal–East Asia–Pacific-like teleconnection. This study could provide a new perspective for a better understanding of the EASM. Significance Statement Recent studies have shown that the mountains adjacent to the Tibetan Plateau have significant effects on the Asian summer monsoon, although these mountains are much lower in elevation and smaller in extent than the Tibetan Plateau. The Southeast Asian low-latitude highlands (SEALLH), located on the southeastern margin of the Tibetan Plateau, influence the East Asian summer monsoon (EASM) via both thermal and mechanical effects. However, the individual thermal and mechanical contributions to the EASM have not yet been clarified. Numerical experiments designed specifically for the SEALLH, which is warmer and wetter than the Tibetan Plateau, show that the thermal effect of the SEALLH on precipitation and the upper-tropospheric circulation over the EASM region is roughly equivalent to the mechanical effect of the SEALLH when its original height was reduced by 50%, but via different physical processes. The thermal effect of the SEALLH induces southerly wind anomalies between the SEALLH and the western North Pacific, influencing the EASM by exciting an East Asia–Pacific-like wave train. The mechanical effect of the SEALLH influences the EASM by exciting an equivalent barotropic Bay of Bengal–East Asia–Pacific-like wave train.

Resumen
Abstract Since China implemented the air pollution prevention and control action in 2013, the aerosol emissions in East Asia have been greatly reduced, while emissions in South Asia have continued to increase. This has led to a dipole pattern of aerosol emissions between South Asia and East Asia. Here, the East Asian summer monsoon (EASM) responses to the dipole changes in aerosol emissions during 2013–2017 are investigated using the atmosphere model of Community Earth System Model version 2 (CESM2). We show that decreases in East Asian emissions alone lead to a positive aerosol effective radiative forcing (ERF) of 1.59 (±0.97) W m−2 over central-eastern China (25°–40°N, 105°–122.5°E), along with a 0.09 (±0.07) °C warming in summer during 2013–2017. The warming intensified the land-sea thermal contrast and increased the rainfall by 0.32 (±0.16) mm day−1. When considering both the emission reductions in East Asia and increases in South Asia, the ERF is increased to 3.39 (±0.89) W m−2, along with an enhanced warming of 0.20 (±0.08) °C over central-eastern China, while the rainfall insignificant decreased by 0.07 (±0.16) mm day−1. It is due to the westward shift of the strengthened western Pacific subtropical high, linked to the increase in black carbon in South Asia. Based on multiple EASM indices, the reductions in aerosol emissions from East Asia alone increased the EASM strength by almost 5%. Considering the effect of westward shift of WPSH, the dipole changes in emissions together increased the EASM by 5–15% during 2013–2017, revealing an important role of South Asian aerosols in changing the East Asian climate.
