库尔勒市霜冻特征及其驱动力分析
The Analysis of the Characteristics of Frost and Its Driving Force in Korla
摘要
Abstract
Using the meteorological data of Korla Municipal Meteorological Bureau from 2003 to 2012 including the minimum surface temperature,minimum air temperature,cloud amount,wind speed and air pressure et al,and then the characteristics of the frost and its relations with the minimum surface temperature and the other meteorological elements were analyzed,and the results were as follows:(1)The frost in Korla mainly appeared in October,November and the next March. (2)The difference value between the minimum air temperature and the minimum ground temperature was -3℃ to 8 ℃,of which 72.5% was between 3℃ to 5℃.(3)When air pressure was lower than 1015 hPa,the probability of frost was only 4.8%,when the pressure was higher than 1025 hPa,the probability was 84.7%.(4)Based on the forecast equation of the minimum surface temperature,which was established from the relationship between the minimum surface temperature and the minimum air temperature,cloud amount and wind speed,the accuracy rate of the minimum surface temperature was 70.7%~83.5%,and that of the frost was 89.9 %.关键词
