1998-2002年横跨美国、南欧和西南亚的干旱通过共同的海洋影响联系在一起。在此期间，热带太平洋东部的冷海表温度（SST）和热带太平洋西部和印度洋的暖SST显着持续。气候模型显示，这些地区分别产生的气候信号协同作用，每个信号都导致了中纬度地区的大范围干旱：这是一个理想的情况。空间扩张，同步干旱的情景。印度洋和西太平洋的变暖是前所未有的，与温室气体强迫一致。对未来的干旱提出了一些建议。
The 1998-2002 droughts spanning the United States, southern Europe, and Southwest Asia were linked through a common oceanic influence. Cold sea surface temperatures (SSTs) in the eastern tropical Pacific and warm SSTs in the western tropical Pacific and Indian oceans were remarkably persistent during this period. Climate models show that the climate signals forced separately by these regions acted synergistically, each contributing to widespread mid-latitude drying: an ideal. scenario for spatially expansive, synchronized drought. The warmth of the Indian and west Pacific oceans was unprecedented and consistent with greenhouse gas forcing. Some implications are drawn for future drought.
