In the period 1998 to 2002 occurred in the United States, southern Europe and southwest Asia, drought events are related to the impact with the sea. During this period, the tropical eastern Pacific sea surface temperatures (SSTs) continue to cool significantly, while the tropical western Pacific and Indian Ocean SSTs was warm weather continued. Climate models indicate that these different waters from the sea surface temperature forcing of the climate response is the interaction, for the mid-latitude regions are widely distributed, synchronized persistent drought, have contributed each area. The warming Indian Ocean and western Pacific are rare, and this warming consistent with greenhouse gas forcing. This trend is also drought in the future some of the views put forward.
