| 摘 要： | 文中设计了热带辐合带综合指数 ,较客观地反映了亚洲季风区深对流活动的气候变化特征。用热带辐合带综合指数分析华北旱涝年季风区对流活动特征 ,结果表明旱涝年对流活动有明显的差异 ,尤其春季东亚和印度季风区的热带辐合带综合指数差异非常显著 ,为华北夏季旱涝预测提供了新的参考依据。

| Abstract: | An intertropical convergence zone(ITCZ) synthesis index is designed, which can demonstrate quite clearly and objectively the seasonal features of deep convection in ITCZ regions. ITCZ activities are analyzed by means of the index for both wet and dry summers of North China. The results show that the differences between wet and dry summers are more remarkable in winter-spring period, especially in Indian and East Asian monsoon regions, which could be able to provide a new method to the prediction of summer rain in North China . |
