To everything, there is a season

David of Grand Rapids asked, "Why is there a difference of seasons as it pertains to meteorologists? For instance, spring started on March 20 this year, but meteorologists say that the meteorology spring runs from March 1 through May 31. It is also the same for the balance of the seasons. What gives on the different dates?"

ANSWER:

George Lessens, chief meteorologist for WZZM-TV, said is strictly done for the simplicity of keeping records. For example, the winter season would include part of a previous year (the end of December), and it goes from there.

So, for record-keeping, meteorologists call December through February as the winter months, March through May is spring, June through August is summer, and September through November is autumn.

"Also, the 'seasons' on the calendar are strictly from an astronomical viewpoint, not a meteorological viewpoint," Lessons said. "Spring 2013 arrived at 7:02 a.m. EDT Tuesday, based on when the sun was exactly over the equator, as the Earth orbits around the sun."
