Abstract:

?利用10年TRMM卫星2A25资料,对东亚热带和副热带季风区对流降水和层云降水的季节变化特征进行了对比分析,研究了热带和副热带季风区降水性质的差异,并结合IPCC第4次报告中24个模式的20c3m模拟资料,对现有模式在东亚热带和副热带季风区关于对流降水及层云降水的模拟能力做了一个简单的评估,分析了模式中可能存在的问题.结果表明:夏季风爆发后,东亚热带与副热带季风区对流降水和层云降水都明显增加,但热带季风区对流降水所占比重明显减少,而副热带季风区对流降水所占比重明显增加,热带和副热带季风区存在明显不同;现有模式对东亚季风区对流降水百分比的模拟普遍偏高,而对层云降水的模拟偏少,这在热带季风区尤其明显;模式较好地模拟出了副热带季风区中对流降水百分比的季节变化特征,而对热带季风区对流降水百分比的季节变化没有正确描述;研究结果表明对流降水和层云降水在时间和空间上经常同时出现,具有很强的伴随性,而模式没有正确描述这种相关性,这可能是模式对层云降水百分比模拟不好的一个重要原因.
