  • 摘要: 利用NECP/NCAR再分析资料、国家气候中心和NOAA相关资料,研究了与2014年浙江夏季低温多雨事件相关的大尺度环流特征和海温因子。结果表明:中纬度我国东部到日本南部气旋性环流异常的存在有利于浙江夏季出现低温多雨,异常偏强偏南的西太平洋副热带高压(简称副高)是8月罕见低温多雨的直接原因;东亚-太平洋型遥相关(EAP)和欧亚型遥相关(EU)是影响浙江夏季低温阴雨的主要遥相关型,当EAP负位相和EU正位相时,冷空气容易堆积和南下,与暖湿气流交汇,有利于降水降温,8月罕见低温阴雨是EAP负位相和EU正位相协同作用的结果。进一步的分析表明ENSO暖位相激发了西太平洋上空强烈的异常下沉气流和反气旋,使得副高偏南偏强,东亚地区呈EAP波列型响应;热带印度洋海温全区一致模态(IOBW)暖位相的维持进一步减弱了8月海洋性大陆地区的对流活动;北大西洋中部海温季内的变化或许与EU位相的转变有联系。
