摘要: 2006年夏季,我国重庆、四川等地持续高温少雨,遭遇特大伏旱,影响严重。初步分析表明,2006年盛夏川渝的异常高温事件可能是受全球变暖和天气扰动共同作用的结果,但以天气扰动的影响为主。大气环流异常,北方南下冷空气活动偏弱,西北太平洋副高脊线偏北以及冬季青藏高原积雪偏少是导致该地区2006年严重高温干旱的直接原因。

Abstract: In the summer of 2006, severe heat wave and drought hit Chongqing municipality and Sichuan Province, causing dramatic economic losses and environmental damages. The comprehensive effect of the weather-related disturbances and global warming may be the reasons for the occurrence of the warm extremes in Chongqing and Sichuan in the summer of 2006, but the random weather-related disturbances contribute most to the local warm extremes in last summer. It is indicated that less cold air activities, northward locations of subtropical high ridgeline, and less snow cover over the Tibetan Plateau in the winter and spring of 2005/2006 are the main three direct causes for the extremely hot and dry weather over the above-mentioned areas in the summer of 2006.

Key words: heat wave, drought, global warming, weather disturbance, Sichuan Province, Chongqing Municipality
