The first morning of winter can either come quicker, or later. The season can start on either “Meteorological winter,” or “astronomical winter”. But for a lot of people, the 1st day of winter season arrives with a snow shovel and a harrowing commute.
Starting Winter season up this year
The first morning of winter this year is Dec. 1 from a meteorological standpoint. The 1st morning of astronomical winter season is the winter solstice, which is December 21st on this year’s calendar. This year, definitions for winter weren't what the climate waited for. It began all on its own. As of Dec. 1, a fantastic deal of the United States had already experienced a few weeks of large snowstorms and sub-zero temperatures. La Nina is what has influenced the climate a lot this year. La Nina is a drop in ocean temperatures across the equatorial Pacific. La Nina brings harsh winter season conditions across the northern U.S.
Two times the 1st morning of winter season
The meteorological winter season began when the northern hemisphere got into its coldest temperatures on average. Dec. 1 was when this happened. From Nov through January the coldest weather is there as it’s when the shortest days are. The coldest temperatures of meteorological winter season could be expected in January, when the snow pack has a maximum cooling effect on the atmosphere. Dec. 21 is when the astronomical winter can be beginning. That is since the northern hemisphere will be having its shortest period of daylight. Days commence to get longer after the solstice. There won't be many more meteorological winter season days left. The astronomical winter season will not end until March 21st, 2011. This could be when the vernal equinox happens.
Winter weather 2010-11
In real life, the 1st day of winter comes too early and the first morning of spring comes too late for those living in the climates most affected by climate and short daylight. Accuweather.com reports the Northwest, Great Plains, Good Lakes and New England will see winter weather the worst. Above normal snow and ice is in the forecast for these regions. Go south if you want relief. There’s a "non-winter" predicted some places. From CA to the Southeast are these areas.
