解釋
西風槽-
The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high, south asia high, low latitude systems, upper level jet ( ulj ), low level greater wind speed axes, westerly trough and plateau trough, low level vortex, cold frontal, occluded front in qinghai lake, mesoscale low pressure, heat low - pressure in qinghai, shear line and convergence line, mesoscale cloud cluster, etc. the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area
3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸；西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強，位置東西擺動預示高原地區將有降水產生，中心強度減弱，降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。 -
While the precipitation of southeast of inner - mogolio is attributed as the strong convective precipitation, the rainfall of liaoning and northeast of heilongjiang is induced by subtropical high and westerly trough, and that of west of heilongjiang is influenced directly by vortex in upper air
各區域產生極端降水的天氣背景也不相同：內蒙古東南部的降水是前傾槽引起的強對流降水天氣，遼寧和黑龍江東北部的降水是由於副熱帶高壓和西風槽的共同作用引起的。黑龍江西部的降水是由於高空渦的直接作用引起的。 -
When the autumn kuroshio ssta is positive, the sea - land sea level pressure differences in the east asian region become large in winter, the east asian trough at 500hpa shifts eastward and is deep in its south and shallow in the northern, along with strong north winds in the above area and weak westerly circulation in the asian region
當秋季黑潮區域海溫異常偏高，東亞地區的海陸氣壓差異進一步加大，東亞大槽北部減弱、南部加深、位置東移，東亞地區的偏北風加強，亞洲地區西風環流減弱，即東亞冬季風加強；反之亦然。
