WX Wise: Reasons for the Seasons
Here in Montana we are subject to all four seasons, but have you ever wondered what the reasons are for the seasons?
One of the main concepts is that earth is tilted at roughly 23.5 degrees.
This may seem minimal, but this tilt means that the sun's rays will hit the earth's surface at different angles at different times of the year.
For example, in the summer months the earth is tilted with the northern hemisphere in a direct line, creating long days and warm temperatures in Montana.
On the flip side, in winter the Treasure State is tilted away from the sun and is stuck with shorter days and colder temperatures.
In addition, as the earth revolves around the sun, the path it takes is actually elliptical.
This path puts the northern hemisphere slightly closer to the sun during summer months resulting in warmer temperatures.
When it comes to the fall and spring seasons, the earth's tilt results in equal heating for both northern and southern hemisphere at that time.
Therefore, our spring and fall equinoxes trigger the beginning of a new season.
And now you're a little bit more weather wise.
