摘要
本文取全省25个代表站1961～2000年7月降水资料和北太平洋海温月平均资料为素材,首先标定典型旱涝年例,其次对比分析典型旱涝年例的海温场特征和可能的影响关系。初步结论有:(1)黑潮区海域海温偏高(偏低)、太平洋中东部赤道附近海域海温偏低(偏高)时,福建伏旱期易于发生干旱(洪涝);(2)ENSO冷(暖)事件影响年时福建伏旱期易旱(涝)。
The precipitation data in July at 25 representative meteorological stations in Fujian Province and the monthly mean sea surface temperature in North Pacific from 1961 to 2000 were selected as material. First, the anomalous precipitation year cases were defined. Next, the sea temperature character and the possible infection relation on anomalous precipitation year cases were contrast analysed. The primary results are found: (1) When sea temperature in Kuroshio current region is on partial high (low) side, sea temperature around equator region in East Pacific Ocean is on partial high (low) side, the drought (flood) is easy to occur in summer season in Fujian. (2) When it is ENSO cold (warm) event year, the drought (flood) is easy to occur in summer season in Fujian.
