谢义炳对大气环流系统研究的贡献

ACADEMICAN XIE YIBING'S CONTRIBUTION OF THE ATMOSPHERIC CIRCULATION SYSTEMS——A REVIEW

  • 摘要: 对谢义炳在大气环流系统方面所做出的科学贡献作了简要的全面回顾。其中包括:(1)北美切断低压的生命史;(2)东亚高空锋和急流的多层结构;(3)中国降水系统的结构和演变规律(包括梅雨锋、西南低涡等),热带和中纬度扰动相互作用在暴雨过程中的重要性;(4)西北太平洋的台风形成在ITCZ(赤道辐合带)/季风槽中;印度西南季风的低频变化;(5)降水系统的湿斜压动力学理论及其在天气预报中的应用;(6)大气环流的中期变化理论。谢义炳的这些贡献为我们更好地理解大气环流系统并改善了中国的暴雨预报。

     

    Abstract: Academican Xie Yibing’s main contribution of the atmospheric circulation systems is reviewed briefly. Which include: (1) The life cycle of the upper cut-off low over North America. (2) The multi-layer structure of the upper front and jet stream over East Asia. (3) The structure and evolution of rain-bearing systems (meiyu front, South-west vortex, etc) over China. The importance of the interaction between tropical and middle latitude disturbances in the heavy rain fall. (4) Formation of typhoon over Northwestern Pacific along the ITCZ/monsoon trough, and the low-frequency variation of the southwest Indian monsoon. (5) Theory of moist-baroclinic dynamics of the rain fall system and apply to weather forecasts. (6) The theory of medium-rang variation of the general circulation. Xie Yibing’s contribution gave us a better understanding of the atmospheric circulation systems and improve the heavy rainfall forecasting over China.
