| 摘 要： | As shown in comparison and study of the HIRS-Tb12 data and conventional data, temperature,
humidity and vertical motion are structured differently in the Southern and Northern Hemispheres, which are well
depicted with the HIRS-Tb12 data. When high pressures rapidly decrease over the regions of South China Sea
and Arabian Sea with the HIRS-Tb12 less than 200 W/m2, monsoons will set off in the South China Sea, Arabian
Sea and Bay of Bengal, respectively. From a year of significant drought to one of significant floods, the trend of
evolution is significantly different in the downdraft areas of the subtropical highs between the two hemispheres. |
