摘要
Abstract
Basing the observational data of daily averaged temperatures,sunshine,and such NCEP/NCAR reanalysis data as monthly sea surface temperature（SST）,daily geo-potential height and wind,from1960-2010 in Fujian province,using statistics method,the spatial and temporal distribution and the anomalous abundant causes of cold and rainy weather during spring sowing period（NDCRWS） in Northern and Southern Fujian were analyzed.The results show that the spatial distribution of the NDCRWS is closely related to the terrain and latitude of Fujian.The NDCRWS has a weak decreasing tendency in the past 51 years.The interannual variation of NDCRWS in the Northern Fujian is similar to that in the Southern Fujian.The NDCRWS in Northern（Southern）Fujian still has an increase（decrease）trend in coming years.The anomalous abundant of NDCRWS are directly caused by the strong meridional circulation in high latitude area of Asia,active cold air,southwesterly wind and abundant humidity.The SST in the North（central and eastern）Pacific during the preceding winter is obviously higher than normal while there are the anomalous abundant NDCRWS in the Northern（Southern）Fujian.关键词
