  Drop in temperature

Somebody has made count, the month with our country strong most cold air is in November. The average temperature December is in northward major area about between ℃ of –5 ℃ ~–20, after southern strong cold air passes, also can appear sometimes frost. Chill is very adverse to the health of body weak and old people.

   Heavy snow (blizzard)

We know, strong cold air often can form bigger range snowfall or bureau ground blizzard. The benefit of snowfall is very much, be helpful for alleviating especially wintry drought, freeze to death farm ill bug, be helpful for what winter travels beginning. But snowfall road slips, change Xue Chengbing, bring about accident of traffic of incur loss through delay of civil aviaton airliner, highway and driveway easily to embrace; The blizzard seal a moutain pass of specific area, Feng Lu still can is opposite prairie of a pasturing area (call white calamity) person cultivate safety causes menace.

   Sleet (pluvial Song)

Strong cold air arrives at south, especially and other places of Guizhou, Hunan, Hubei, appear easily sleet. Sleet is the snowflake that from headroom cold layer descends, melt sometimes to middle-level Cheng Yu, to low altitude cold layer, although,become temperature again under 0 ℃ , but remain drip-drop cross cooling water. Too cooling water drops from inside sky, reach the floor when it, come up against ground when any objects, happen immediately freeze, formed sleet. When occurrence sleet, a cobbly appears to put housing on the ice on the ground and object, can cause great effect to traffic, electric power, communication, still can cause a fruiter to mar. Basis ” in the Yangtse River downstream climate ” the statistic in one book, annual in December, air temperature of downstream in the Yangtse River area is when –3~0 ℃ , appear easily sleet, sleet occurrence odds is occupied 76% .

  Mist Song

According to statistic, will begin every year in November commonly second year in Feburary, northwest, northeast and greater part of catchment of the Yangtse River, meet early or late misty Song appears, humidity is big a mountainous area see more quite. Mist Song is the lunt in the air when microtherm direct sublimate, or super-cooling droplet is frozen directly, in the deposit of ivory ice crystal on the object. Day of Song of mist of our country winter counts much place to have: Shaanxi is north of Heilongjiang, Jilin, Xinjiang, upper. Among them, the mist Song with Jilin is most famous, successive mist Song of a few days, world of formation ice and snow, the person that lets like travel and photography is surprizing unceasingly.

  Ice run

Winter, reach of Inner Mongolia Baotou is frozen Feng He, and slant the Lanzhou river south does not have Feng He, river water flows to the reach that has sealed a river, because seal the ice on the reach of the river,layer and approach dam stopped the river water that upper reaches comes down, force water level drive up, unboiled water is produced easily to overflow the calamity of dike in Baotou reach. If strong cold air comes late, cause disaster drifting approach easily in December, be worth to pay close attention to.
