摘要
应用ｐ－σ五层原始方程模式，以实际观测得到的阿拉伯海、孟加拉湾异常热源为依据，进行了一系列敏感性试验，研究了１９９４年７月我国东部降水异常的成因。结果表明，阿拉伯海、孟加拉湾上空异常热源的维持是造成这次我国华南华北涝、江准流域干旱的重要因子。此外，还对异常热源的影响机制作了讨论。
A primitive equation model is used in this paper to study the effects of the heating source anomalies over the Arabic Sea and Bay of Bengal on precipitation in the eastern China in July,1994.Numerical results indicate that the heating source anomalies persisting over the Arabic Sea and the Bay of Bengal are the important factors of the precipitation anomalies in the eastern China in that year.The mechanisms of the effects of heating source anomalies are also discussed in this paper.
