2010年广西高温热浪气象灾害成因分析
Analysis on the Causes of 2010 High Temperature Heat Wave Meteorological Disasters in Guangxi
摘要
Abstract
Based on the daily temperature data of Guangxi and the NCEP/NCAR reanalysis data during 1951-2010, the causes of maximum temperature in 2010 have been investigated by using Morlet wavelet analysis method. The results show that the maximum temperature exhibits a increasing tendency on a long-term basis and displays significant characteristics of periodic oscillations, all with stronger 12-14 and 10- yearly periods. The partial strong of subtropical high strength, shifted westward of ridge line position, and domination of the strong subtropical high press are all the main cause of maximum temperature in 2010. The center of typhoon at the field （20~24？N , 116-121？E） and the most parts of Guangxi are under the control of downward current. Furthermore, the small area size of polar vortex in 2010 summer was and the displacement of polar vortex towards Western Hemisphere lead to the weakening invasion of the cold airs, and this were also the cause of hot weather in Guangxi.关键词
