The cold whipping across an Alabama field on this winter morning slaps away the warmth, slowly forcing fingers and toes numb. Under a dull, overcast sky, University of Mississippi researchers trek across a damp pasture just north of Huntsville, braving the freeze and checking an array of 12 sensors that scientists at the UM National Center for Physical Acoustics are using in their research into tornado detection and tracking.

Spring: March 1-May 31; Summer: June 1-August 31; Fall: September 1-November 30; Winter: December 1-February 28 (29)

You may have noticed that Arbor Doctor, meteorologists and climatologists define seasons differently from “regular” or astronomical spring, summer, fall, and winter. So, why do  meteorological and astronomical seasons begin and end at different times? Read more here>>>

Nearly half the country has had its coldest day by the first day of calendar winter. That is why meteorological winter makes the most sense.
