Clarifying the difference between meteorological and astronomical spring

EAST TEXAS (KTRE) -

Now that February is in our rear-view mirror and March is here, we are now officially in meteorological spring.  In hearing this, many of you may be confused.  After all, astronomical spring, which arrives around March 20th each year, is what many of you use to welcome in the spring season.

There is a difference in the two spring seasons, so let me clarify the difference between the two so you will not be confused.

Meteorological spring is defined as the three month period that runs from March 1st through May 31st.  We use this three month period to define our weather records and the temperature cycle.  The amount of rain and the temperatures we experience over the next three months will be a part of the 2016 spring season, just like the three month period from November through February is defined as meteorological winter.

Astronomical spring, often referred to as the vernal equinox, is directly tied into the earth’s rotation and tilt on its axis in relation to the sun.  This is the day in which the sun’s rays are directly over the equator and we receive an equal amount of daylight and darkness.
