Meteorological spring begins-- but, what is it?

SOUTH MISSISSIPPI (WLOX) -

With March 1 began the season of meteorological spring. It starts a little earlier than the official calendar, or astronomical, spring season that most are more familiar with.

Why is this? It has to do with the spring equinox.

No, not the car-- it's the moment when the sun's rays are directly over Earth's equator. This moment falls on a slightly different date each year due to Earth's imperfect orbit. This is why the season begins on a different date each year.

Such a variation could throw a monkey wrench into keeping consistent weather records each year. So, meteorological seasons were created to make it easier to more accurately collect climate data based on our temperature cycle and calendar.

Here's a breakdown of our meteorological seasons

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

Again, meteorological spring isn't a real season. It's mainly a climate record-keeping period for meteorologists.

2017's calendar spring will officially begin on the spring equinox at 5:29 P.M. CDT on Monday, March 20 when the sun will be angled at 0°.
