中文摘要：

利用我国地面气象观测站1961～2006年5～10月的逐时降水数据,通过以降水峰值为中心进行各站的降水事件合成,分析研究降水演变过程的气候特征.分析结果首次揭示了降水过程的不对称性,即降水开始至达到峰值的时间较峰值发生后至降水结束的时间明显偏短.进一步综合考虑不同降水强度、持续时间、峰值发生时间和区域差异的影响后发现：这种不对称性在强降水事件中更为明显;在青藏高原东侧、横断山脉和云贵高原等海拔较高且地形复杂的区域更为突出;短时降水事件的不对称性更强,但区域差异很小;持续时间较长的降水事件的不对称性相对稍弱,但东西差异明显;降水峰值出现在下午至前半夜的降水事件的不对称性最强,而出现在上午的最低.另外,降水事件峰值时的降水强度突出,说明降水峰值前后的强度增减都很迅速.上述结果不仅增进了对降水演变过程的认识,同时也为检验数值模式对降水演变过程的模拟能力提供了评估标准.另外,我国中西部地区这种强降水过程的显著不对称性应在滑坡、泥石流等地质灾害防御相关工作中给予高度关注.
