华南前汛期暴雨
rainstorm during pre-rainy season in South China
hua’nan qianxunqi baoyu华南前汛期暴雨(rainstorm during Pre-rainy season in South China)每年4一6月发生在中国南岭以南地区(包括广东、广西和福建三省、区)的暴雨。华南地处亚热带,受夏季风影响较中国其他地区为早,3月末至4月初即进入汛期,4月至9月为暴雨季节,其中4一6月称为前汛期,这时产生暴雨主要为锋面、低空急流、切变线、低涡等温带天气系统;7一9月为后汛期,·暴雨主要由台风和东风波等热带天气系统所造成;华南前汛期多年平均暴雨日数可达4天以上,以5月最多,6月次之、4月最少。特大暴雨几乎都出现在5月和6月。暴雨中心与年雨量的多雨中心一致。在广西暴雨中心位于桂林附近的桂北地区,在广东省有3个暴雨中心;第一个在云开大山的迎风坡恩平、阳红附近;第二个在九连山的迎风坡清远、佛岗和龙门一带;第三个在粤东沿海和莲花山迎风坡一侧的潮汕平原一带。在福建暴雨中心位于闽北武夷山区。暴雨中心区,暴雨量约占全年降雨量的三分之一。前汛期暴雨过程短的不足1天。长的可达5一7天。华南地区降雨强度一般比内陆地区大得多,24小时暴雨量达100一200毫米比较常见,特大暴雨可达800毫米以上,暴雨过程总量可达1000毫米以上,前汛期暴雨是一次次冷暖空气交绥的结果。当东亚大气环流由冬季形势向夏季形势调整时,西太平洋副热带高压逐渐加强,西南和东南暖湿气流进入华南地区;由北方南下的冷锋移至华南趋于准静止状态,形成华南静止锋。高空西风槽在华南形成切变线,在锋后槽(切变线)前容易形成暴雨。地形作用促使华南前汛期暴雨中心多半集中于山脉的迎风坡。 (黄忠怒)
