circulation pattern
2.Flood in the west of Sichuan Basin is associated with the circulation pattern that two ridges located Ural and the East of Asia respectively, and a trough between Balkhash and Baykal.
3.Analyzed the heavy snow during 15～ 20 in January 2003 in Altay, and explained the benefit condition for snowfall in large region through circulation pattern, vapor condition and dynamic condition, etc.
4.A nalysed the circulation pattern,physical quantities,and numerical we ather prediction products of heavy precipitation weather in Bayangoleng Mongolia Aut onomous Prefecture from 16to18,and21June of 2002,some conclusions were obtained.
5.The dynamic significances of the circulation pattern of Jun 26th ,1999 are documented at the end of this paper from the mass angular momentum and moisture circulation perspectives, which suggest that the configure having cyclonic inwards and anticyclonic outwards in lower and upper troposphere respectively is of great benefit to the conservation of mass and angular momentum in the whole atmosphere.
6.The result shows that: (a) The BOM can reproduce the main Arctic Ocean circulation pattern, (b) The "Islandization" which is commonly used in OGCMs to treat the North Pole, not only influences the ocean current near the pole, but also influences the current in the Northern Atlantic Ocean, thus the bogus island might influence global climate through thermohaline circulation in the Atlantic Ocean.
7.In addition, the CTD data from the measurements are used to provide the scientific evidence for the longitudinal circulation pattern in CDW and AABW, which is coincident with the features of deacan cell, sub polar cell and deep cell in the Southern Ocean.
8.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.
9.The former mainly appears in April accompanied with typical transient circulation pattern from winter to summer, strong subtropical westerly jet streams prevailing in the high level and steady stratified atmosphere while the moisture is mainly originated from the westerly transport over Arabian Sea and the easterly transport at the south side of WPSH;
10.Flooding frequency has an increasing trend in Aksu River basin since 1987. 500 hPa circulation pattern of mixed flood in flooding season of Aksu River basin is characteristics of Xinjiang High ridge steady over middle and east parts of Tianshan Mountains, and north boundary of 5 880 gpm height line steady in /over Tianshan and North Xinjiang regions and west boundary extend to south Xinjiang closed to Pamirs Plateau, and subtropical low trough in central Asia.
