摘要
本文利用陕西省关中平原地区自西向东的宝鸡、泾阳、西安、潼关 4个观测站的逐日气温资料和逐日降水资料 ,分析了关中平原 195 7年到 1972年 16年间本区春季气温、降水与春季低温天气的关系。揭示出关中平原地区春季低温天气发生次数与春季气温存在负相关性 ,与春季降水存在正相关性 ;在所研究的时间段内 ,关中平原地区气候变化趋于冷干 ,春季气候变化趋于冷湿 ,该区春季低温天气的天数趋于增多 ;低温天气的出现与温度的变幅有一定关系。
In this paper, the relationship between air temperature and low temperature weather in spring in Guanzhong region had been analyzed by using daily air temperature data and daily rainfall data of 4 stations in Guanzhong region during 1957-1972.The analysis results show that there exists negative correlation between low temperature weather and air temperature in spring, and the positive correlation exists between low temperature weather and rainfall in spring here. During the period studied the climate became colder and arid, and the climate in spring turned to colder and wetter, and the days of low temperature weather increased in Guanzhong region. Some correlation exists between eoccurrence of low temperature weather and fluctuation of air temperature.
