2022年延安市气候影响评价

Climate Impact Assessment of Yan’an City in 2022

利用2022年延安市国家气象观测站常规观测资料,以及2021年及历年(1991—2020年)数据对2022年气候影响进行分析。结果表明,2022年延安市全年平均气温较常年偏高、平均年降水量较常年偏多、日照时数较常年偏少,全年遭遇了5次寒潮天气过程,3次低温霜冻天气过程,5次大的降雹过程,还出现了阶段性高温、干旱、洪涝等灾害性天气过程。综合气象条件,对农业生产利大于弊。

Based on the conventional observation data of Yan’an National Meteorological Observatory in 2022 and the data of 2021 and calendar years(1991~2020),the climate impact in 2022was analyzed.The results show that the annual average temperature in Yan’an City in 2022 is higher than that in normal years,the average annual precipitation is more than that in normal years,and the sunshine hours are less than that in normal years.There were five cold wave weather processes,three low temperature and frost weather processes,five large hail processes,and some disastrous weather processes such as periodic high temperature,drought and flood.Comprehensive meteorological conditions have more advantages than disadvantages for agricultural production.
