How long has it not rained in Beijing?

There has been no effective precipitation in Beijing for 100 days. According to the forecast of the Municipal Meteorological Observatory, the days without precipitation will continue for some time. Meteorologists say that if it doesn't rain or snow for a long time after spring, meteorological drought may turn into agricultural drought. Zhang Peiqun, director of the Climate Application and Service Office of the National Climate Center, explained that the lack of rain and snow in Beijing is closely related to the drought in the north. First, the cold air in the north is very strong, and second, the subtropical high over the western Pacific is relatively weak. Subtropical high is very weak in transporting water vapor in China. Under the action of strong cold air, there is basically no effective intersection of cold and warm air in the north, resulting in meteorological drought in the north. According to Sun, chief forecaster of the Municipal Meteorological Observatory, there will be no rain or snow in the next 7 days to 10. Will Beijing have a snow-free winter? Wang Xiuwen, chief forecaster of the Central Meteorological Observatory, said that it is still uncertain. According to historical statistics, there was snowfall in Beijing in February, and there was snowfall in March in some years. "But there has been no snowfall so far, which is definitely not normal."
