【摘要】 以西北太平洋海温和湖南洞庭湖区汛期降水为基本资料，分析前一年秋冬季黑潮暖流区海温与洞庭湖区汛期降水和洪涝的关系。结果表明，洞庭湖区汛期降水与前一年秋冬季黑潮暖流区海温之间存在着十分显著的遥相关关系，黑潮暖流区海温异常是导致大气环流异常，造成洞庭湖区汛期降水异常和洪涝发生的重要气候背景之一。利用该区域海温变异预测洞庭湖区汛期降水趋势效果较好。更多还原

【Abstract】 Using the ocean temperature of Northwest Pacific and the precipitation in summer of Hunan,the interconnection between Kuro shio from last autumn to last winter and the precipitation and flood in summer in the Dongtinghu area were analysed.The results show that the interconnection between the Kuro shio in the period and the precipitation and flood in summer in the Dongtinghu area is very outstanding.The anomaly of Kuro shio is an important background of climate that influences precipitation anomaly and flood in summer in the Dongtinghu area.更多还原
