摘要对厄尔尼诺-南方涛动（ENSO）相关气候模式的半球和区域分析表明，美国东南部地区，特别是冬季对ENSO有强烈的响应。作者以佛罗里达为例，重点研究了该区域内的局部尺度模式，以研究与厄尔尼诺/南方涛动有关的季节性降雨和河流流量的地理变异。48年（1950-98年）的降水和河流流量数据在佛罗里达进行了分类，使用赤道太平洋的海表温度异常数据，发生在厄尔尼诺（温暖事件），拉尼娜（冷事件），或两者都没有（中性）。季节性降水和径流对ENSO都有很强的响应，表现在它们与Nino-3.4海温异常的关系上。佛罗里达并不作为一个统一的区域响应ENSO，特别是在狭长地带和佛罗里达最南端的地区的降水。特别是，季节性河流排放量...
Abstract Hemispherical and regional analyses of climatic patterns relating to El Nino–Southern Oscillation (ENSO) indicate strong responses in the southeastern United States, especially during the wintertime. Using Florida as an example, the authors focused on local-scale patterns within this region in order to examine the geographic variability of seasonal rainfall and river discharge as related to ENSO. Forty-eight years (1950–98) of precipitation and river discharge data in Florida were classified, using sea surface temperature anomaly data from the equatorial Pacific Ocean, as occurring during an El Nino (warm event), La Nina (cold event), or neither (neutral). Seasonal precipitation and streamflow both exhibited strong responses to ENSO as shown by their relationships to Nino-3.4 sea surface temperature anomalies. Florida does not respond as a uniform region to ENSO, particularly with respect to precipitation in the Panhandle and the southernmost areas of Florida. In particular, seasonal river discha...
