Abstract
Based on the observation data of frost in Jingdezhen during 1971-2015,the characteristics of frost climate change have been systematically analysed and the results are as following:In the past 45 years,the frost days showed an overall decreasing trend with a rate of-0.408 d/10a.In 1970 s,the frequency of frost days reached a peek accounting for 27.2% of the total number,followed by 1980 s with a number of 24.8%.After 1990 s frost days gradually reduced by time.Frost usually occurred mainly from November to March of next year.While some occasionally appeared in April and October,but appeared a less likely chance.During the past 45 years the first frost date has a delayed trend of 2.8 d/10a,while final frost date showing a overall trend in advance with the rate of 3.8 d/10a.By analysing the weather situation and the meteorological element characteristics,this paper also expounds the forecast method of frost climate change in Jingdezhen.关键词
