摘要
从大气环流、海温、太阳黑子、台风等方面分析了 2 0 0 0、2 0 0 0 1两年河南汛期降水差异原因 ,结果表明 :5 0 0hPa环流形势的差异是两年降水差异的原因之一 ;2 0 0 1年登陆台风较多 ,且多位于水汽通道上 ,阻挡水汽向河南输送 ,这是 2 0 0 1年较 2 0 0
Through analyzing the general circulation of atmosphere, sea-surface temperature, sunspot and typhoon. We acquire the cause of 2000 and 2001 precipitation distribution difference of Henan flood season. The reasons show that 2000 and 2001 precipitation difference of Henan flood season is 500hPa circulation pattern difference, is better of landed typhoons of 2001 and typhoons situating the moisture channel because they bock off moisture flux going to Henan.
