Road of the city zone will not get firn and way frozen influence, but north and western a mountainous area need to notice to be on guard firn influence.

Why did Chun Nuanhua open Beijing to return meeting experience blizzard? Actually, cold air comes to spring raid north to see snow more easily. When winter, although cold air strength is enough, but because lunt condition is poorer, north often sees the sign of snow hard, china north area blame very. Arrived after the Beginning of Spring, air of changes in temperature is more active, carry northward lunt more, the lunt nature of plentiful brought greater opportunity seeing snow to north.

From the point of statistical data, this is not Beijing's latest snowfall. According to south outskirt observatory is the latest eventually snow day is monitored, history on the latest Beijing area eventually snow day is on April 21, 1959. Beijing snow had appeared 12 times in April, mixed 1964 among them 1988 is the snowfall that appeared that day in tomb-sweeping day. But return later from 1988 not reappear waved in April the circumstance of snow, today's snowfall will become nearly 30 years to waved first in April snow.

Beijing has entered spring, the chill of this arise suddenly is " pour spring chill " , pouring spring chill is spring later period commonly after already warm period of time, appear to drop in temperature continuously and drop in temperature the case with bigger range. Guo Jianxing of expert of Beijing major observatory thinks, "This still does not calculate go up spring chill " , at present Beijing is in early spring level, warm suddenly cold still it is its characteristic.
