Diagnostic Analysis of High Temperature Process on June 7-8, 2011 in Pingdingshan
Abstract：It appeared more than 40 ℃ high temperature in the most parts of Pingdingshan on June 7-8, 2011. Especially June 8, the highest temperature of seven automatic stations of Pingdingshan reached 40 ℃. Using NCEP reanalysis and routine sounding data, we analyzed this extreme high temperature process. The results indicate the main influence system of this process is warm ridge at 700 hPa and surface warm low-pressure ; the weather of Pingdingshan is clear on June 7--8, 2011, which is better for emerging of high temperature of Pingdingshan because sun radiation. Diagnostic analysis of physical quantity indicate the upper-air of Pingdingshan is desiccated when high temperature process happened as well as following strong descent of air and obvious warm advection, which are better for emerging of high temperature.
