DENVER (CBS4) – For a meteorologist or a climatologist the first of December is an important date because it marks the start of meteorological winter.

Those who work in the fields of weather and climate break the seasons down into three month segments based on annual temperature cycles as well as the calendar.

The astronomical calendar, which says winter will arrive this year on December 21, is based on the natural rotation of Earth around the sun and it defines the seasons with two solstices and two equinoxes.
