| 摘 要： | 本文通过整理右旗1969—2018年气温逐年气象观测资料，对右旗近50a平均气温年际变动、季节性变化趋势、突变特点展开研究。得出结论：50a来右旗温度呈0.39℃/10a的速度增加，在20世纪九十年代之后増温明显，且有显著的阶段性波动特点。季节性气温都是以不同速度在增加，春季平均气温增加发展趋势在四季中极为明显。由最高气温季节平均值可知，春季最大，其次秋季夏季冬季，由此可知，最低温度季节性均值是春季最大，其次夏季秋季冬季。年和四季平均最低气温的增加波动,使得平均气温日较差呈减小态势。

| Abstract: | This paper studies the interannual changes, seasonal trends, and abrupt changes in the average temperature of Youqi in the past 50 years by collating the annual meteorological observations of the temperature in Youqi from 1969 to 2018. It is concluded that the temperature of Right Banner has increased at a rate of 0.39 ° C / 10a since 50a, and the temperature has become obvious after the 1990s, and it has obvious characteristics of periodic fluctuations. Seasonal temperatures are increasing at different rates, and the increasing trend of spring average temperature is extremely obvious in the four seasons. According to the seasonal average of the highest temperature, it is known that spring is the largest, followed by autumn, summer, and winter. From this, it can be seen that the seasonal average of the lowest temperature is the largest in spring, followed by summer, autumn, and winter. The increase and fluctuation of the average minimum temperature of the year and the four seasons make the daily temperature difference decrease. |
