吐鲁番盆地一次极端高温天气过程分析

An Analysis of Extremely Hot Weather Process on Turpan Basin

摘要: 本文对2010年6月15日~6月22日吐鲁番盆地出现的连续高温天气进行了分析，结果表明：此次高温天气主要是由于受深厚暖高脊持续控制，新疆脊与西太平洋副高在新疆叠加形成闭合高压中心，高压系统区存在较强的下沉运动引起的；同时由于盆地地形特有的聚热作用与地面热低压东移的共同影响，盆地高温出现增幅。

Abstract: In this paper, a continuous hot weather process was analyzed on Turpan basin from June 15 to June 22, 2010. The results showed that: The hot weather is mainly due to the continuous control of deep warm high ridge. Xinjiang ridge and western Pacific subtropical high formed a closed high-pressure center in Xinjiang. Strong sinking motion at high- pressure system caused the process. At the same time, due to the combined effect of the topography of the basin-specific poly-thermal effects and the eastward shift of the ground thermal low pressure, high temperature of the basin increases.
