摘要:

利用2003—2014年6—8月CMORPH 3 h衛(wèi)星降水資料，統(tǒng)計(jì)分析北半球夏季對(duì)流性降水的空間分布，發(fā)生的概率，日變化以及其對(duì)厄爾尼諾事件的響應(yīng)等特征。結(jié)果表明，對(duì)流性降水在6—8月除了發(fā)生于熱帶輻合帶等海域外，北美中部，東南亞和熱帶非洲等陸地區(qū)域更為突出。其降水強(qiáng)度發(fā)生在10~11 mm·h^-1之間的概率最大，極端強(qiáng)對(duì)流性降水發(fā)生在陸地上的概率大于海洋。對(duì)流性降水的日變化表現(xiàn)為，陸地上于傍晚（18—20時(shí)）和夜間（22—01時(shí)）有兩個(gè)峰值；海洋上對(duì)流性降水多出現(xiàn)于夜間到早晨這段時(shí)間，而下午出現(xiàn)的概率最低。厄爾尼諾發(fā)展年，海洋上對(duì)流性降水增強(qiáng)，而陸地上發(fā)生的概率總體偏小，衰減年則相反；中國(guó)東部，尤其是長(zhǎng)江以南地區(qū)的非對(duì)流性降水在厄爾尼諾發(fā)展年，多于正常年，與對(duì)流性降水的響應(yīng)不一致。

Abstract:

Based on 3-hour CMORPH satellite precipitation data during 2003-2014, the convective precipitation characteristics of spatial distribution, occurrence probability, diurnal variation and its response to the El Niño were analysed. Results show that the convective precipitation is mainly distributed on the ocean near ITCZ, central North America, Southeast Asia and tropical Africa, etc. The convective precipitation occurrence probability is the largest between the intensity of 10-11 mm·h^-1, and the probability of extreme strong convective precipitation of land is greater than that of ocean. The diurnal variation of convective precipitation is presented with two peaks on land, in the evening(18-20 LST) and midnight(22-01 LST). And its occurrence probability is lager between midnight and morning on ocean. The convective precipitation increases on ocean and decreases on land in developing years of El Niño, while the weakening years are opposite. Nonconvective precipitation on the eastern part of China is more during the El Niño years than that during normal years, and the results are different form the response of the convective precipitation.
