库布齐沙漠腹地与周边地区气温差异对比分析

Comparison of the Temperature Difference between the Kubuqi Desert and and the Aurrounding Areas

利用新建区域自动气象观测资料,选取5个分别位于库布齐沙漠腹地、沙漠边缘、沙漠周边黄河河谷的区域自动气象站,分析了2020年8月—2021年7月期间逐月气温数据。通过对比分析发现:(1)受下垫面物理性质差异影响,沙漠腹地站月平均气温、月平均最低气温变化幅度均大于黄河河谷站;(2)沙漠腹地站月平均最高气温和极端最高气温基本高于黄河河谷站;(3)沙漠腹地站与沙漠边缘站的气温对比规律性相对较弱。

Using the newly-built regional automatic meteorological observation data,five regional automatic meteorological stations located in the hinterland of Kubuqi desert,the edge of the desert and the Yellow River valley around the desert are selected to analyze the monthly temperature data from August 2020 to July 2021.The results showed that:(1)Affected by the difference of physical properties of underlying surface,the variation range of monthly average temperature and average minimum temperature in the hinterland of desert is greater than that in the Yellow River valley;(2)The monthly average maximum temperature and the extreme maximum temperature in the hinterland of the desert stations is basically higher than that of the surrounding Yellow River Valley stations;(3)Compared with temperature,the hinterland of the desert stations and the desert edge have no regularity.
