夏季索马里越赤道气流垂直结构特征及其与南亚夏季风的关系
Vertical structure of summer Somali cross-equatorial flow and its relationship with South Asian monsoon
摘要
Abstract
Based on the monthly NCEP/NCAR reanalysis wind field data from 1950 to 2009, the vertical structure variation of summer Somali cross-equatorial flow and its relationship with South Asian summer monsoon are analyzed. Results show that summer Somali cross-equatorial flow increases firstly at low level in vertical direction, then it gradually weakens after reaching maximum at 925 hPa. The height of Somali cross-equatorial flow core can extend to 850 hPa in some years, while maintains at 925 hPa in some other years. The South Asian summer monsoon is different with the vertical structure of Somali cross-equatorial flow changes, and the difference mainly embodies variation of lower troposphere wind field and the intensity difference of South Asian summer monsoon. In general, South Asian summer monsoon becomes strong (weak) when Somali cross-equatorial flow core extends to 850 hPa(lies at 925 hPa).关键词
