monsoon wind
2.The rsults are as follows: (1) precipitation shows the decreasing trend and remarkable interannual and interdecadal variations in flood season in the last 44 years. (2) precipitation anomalies in flood season have a good correlations with southwest and southeast summer monsoon, polar vortex, west wind trough, the subtropical high over West Pacific and South Asia High.
5.WIND AND TEMPERATURE CHANGES OVER EURASIA DURING THE ACTIVE, BREAK AND WITHDRAWAL TIME PERIODS OF THE INDIAN SUMMER MONSOON OF 1979
7.The loess features appear mainly wind phase with the wind--water two phases by calculating grain size prameters and analysing the grain--size. The high content of clay(<5 μm), with the average of 54.32%, and mulistory calcareous loess layers indicate that it is formed in the condition of moist climate, dominating summer monsoon.
9.This paper analyzes u filed data of monthly mean for 12 years during December of 1985 ~ November of 1997, finds wind field has obvious quasi-biennial oscillation (QBO) between east Asia monsoon region and South Asia monsoon region , but they have different propagation in meridional, zonal and normal ,and propagation direction is different in 850 , 500 and 200hPa , even it is opposite.
10.The cold air could reach low latitude area when the stable meridional circulation pattern controls the Southern Hemisphere. The strong southeast wind to the north of lower layer cold high located behind the long wave trough could form a strong and persistent cross-equator flow in a relatively fixed narrow channel. In some favorable conditions of Northern Hemisphere circulation, this cross-equator flow could turn into southwest flow over the Northwest Pacific and lead to intensification of southwest monsoon.
