摘要:
利用2014年海南省18个气象站逐日最高气温和NCEP/NCAR1×1再分析资料,采用天气学诊断分析方法,分析了2014年5-6月海南省持续性高温天气过程的成因,结果表明:(1)强高温出现在中北部,与副热带高压和西南热低压活动有着密切的关系;(2)低层水汽含量小,海南岛处于弱的水汽输送通量辐散区,有利出现晴热天气;(3)西南季风经过中南半岛长山山脉后,海南岛处于其背风波的下沉气流区,产生压缩增温效应,是这次高温天气发生的重要原因。
Abstract:
Based on the daily maximum temperature of 18 stations in Hainan in 2014 and 1 x 1 NCEP/NCAR reanalysis data, the causes of continuous high temperature weather process during may to June in 2014 were analyzed by the synoptic diagnostic analysis method. The results showed that:(1) the severe high temperature occurred in the north-central region has close relationship with the southwest subtropical high and thermal low-pressure activity; (2) low water vapor content in lower layers and the weak water vapor transport flux controlling Hainan area are both favorable to the sunny hot weather; (3) after the southwest monsoon passed through the long mountains of Indochina, Hainan island is in the sink of its leeward slope, which result in compression and warming effect. All above are the important reasons for this hot weather.
