Based upon a systematic review on the study of subtropical anticyclone, in this study, the mechanism linking the formation of subtropical anticyclone in boreal summer to zonally asymmetric diabatic heating is investigated via data diagnosis, theoretical study, and numerical experiment. The complete form of the tendency equation for vertical vorticity development, the NCEP/NCAR reanalysis data, and the IAP/LASG GOALS climate model are employed for the study.

Integrated analysis of 7 times heavy rain in Yunnan from July 19 to August 2 based on actual observation weather datum and satellite cloud atlas and Doppler radar image. The results show that: high-low southwest jet stream is important effect system. The maintenance of southwest jet stream provides water vapor, momentum, fast transfer of unstable energy for the lasting heavy rain. The further configuration of plateau shear line and southwest jet stream is necessarily condition about 7 times heavy rain. The lasting heavy rain appeared on big value region of 500hPa vapour flux and vapour flux divergence. The shear cloud band and subtropical high cloud band crossed and confluenced in Yunnan on the satellite cloud atlas. The maintenance and intensification of shear cloud hand and periphery cloud band of subtropical high correspond quite well to heavy rain falling region and cloud band distribution.

Thanks to the western Pacific subtropical high, connecting the mid-latitude with the low-latitude circulation; meanwhile, its location and intensity obviously impact on the rain belt, storm rainfall, dryness-wetness, and typhoon track of China, studying the evolution law of the western Pacific subtropical high, has very important theoretic and realistic significance.

As a result, a weak indirect cell is formed in high latitudes. By the 36th time step, the model atmosphere accomplishes the transition form one-cell circulation to two-cell circulation. There is a momentum source in the upper subtropical region. During the transition, the"polar westerlies jet"gets weakened and vanishes at the end, while the subtropical westerlies jet gets strengthened. At this two-cell stage, the generation and dissipation of westerly angular momentum do not balance each other, and the atmosphere is still at an unstable state with great surplus of angular momentum generation.

By analyzing next-spring abnormal features of 500 hPa height and 850 hPa, 200 hPa meridional wind due to Nino3 SST rising, it is found that Nino3 SST rising abnormally in the second half year leads to 500 hPa height field rising in the tropic and Northwest Pacific subtropical region, namely the Northwest Pacific subtropical high is stronger and shifts westwards and northwards compared with the mean, and the trough over East Asia is weaker with its location shifts eastwards; the height field falls from the area around Balkhash to Baikal Lake, i.
