摘要:

根据2021年春季沙尘暴监测数据、气象数据等,分析了2021年春季我国沙尘天气发生时空特征。结果表明:2021年春季我国沙尘天气次数偏少、日数偏多、沙尘过程时间偏长;沙尘天气强度偏强、影响范围偏大;沙尘主要起源于蒙古国南部进而影响我国北方地区;2021年春季是我国近20年沙尘天气同期影响较强的时期。

关键词: 沙尘天气, 沙尘暴监测, 时空特征, 原因分析

Abstract:

Based on the dust storm monitoring data and meteorological data in spring 2021,the study analyzed spatio-temporal characteristics of dust weather in China.The results showed that the frequencyof dust weather in spring 2021 was less,the number of dust weatherdays was more,and the duration of dust process was longer.The intensity of dust weather was strong and the influence range was large.It mainly originated in southern Mongolia and then affect the north of China;The spring of 2021 was the period with strong influence of dust weather in the past 20 years.

Key words: dust weather, dust storm monitoring, characteristic, cause analysis
