摘要
在中期环流分型预报的基础上 ,对宁夏 1 971~ 2 0 0 0年 30年第一场透雨过程的环流形势及主要影响系统特征进行了深入分析。同时 ,利用NCEP/NCAR( 1 979~1 999年 )候平均全球再分析资料 ,计算并分析了各环流形势下透雨过程候及前一候的平均环流特征场 。
Based on the medium range classified circulation pattern,the atmospheric circulation pattern and main weather system which affected on the first soaking rain in Ningxia during 1971—2000 are carefully analyzed.Moreover,the characteristics of average circulation pattern between the pentad when it rained and its previous five days are calculated and analyzed.At last,the medium range notional models under the main circulation patterns for forecasting the first soaking rain are established by using the mean global per five days reanalyzed data of NCEP/NCAR during 1979—1999.
