Each revolutions, positions the earth a little bit closer/farther from the sun than the prior orbit. Thus, there will be those seasons which are hotter or colder accordingly
To illustrate precisely how this works, dig the old Spirograph out of the attic and do an elliptical pattern . The center of the page would represent the sun. Wherever your pen is on the page, would represent the earth in orbit around the sun. One complete ellipsis form starting point back to starting point equals one year (4 seasons) . Note that Summers and winters are the extreme ends of the ellipsis, where as Spring and fall are on the sides of the ellipsis. Some years, the earth is closer to the sun than it was a year prior, and so on.
Knowing this... I believe that our weather anomolies, come and go accordingly[/quote. The Earth is CLOSER to the Sun in Winter than in Summer. If I remember correctly there is a slight wobble of the Earth's axis that makes the Sun's rays more direct in Summer. Whether we have a hotter or colder season than normal may be more influenced by the Sun's activity. During this latest global warming anomoly Mars has heated up iin the exact same proportion as the Earth. This leads me to believe that man has little to do with global warming. In 1936 there was a town in North Dakota that recorded the highest temperature ever recorded in that state, something like 121 degrees. The very next February a town nearby recorded the all time low for North Dakota, 60 degrees below zero. So within six months there was a swing of 181 degrees! I wonder if back then people thought it was the End Times.
I always thought its the duration of exposure, facing the sun, which dictated the seasons: Note the slash here, which represenst the axis (tilt of the earth) and the Asterisk, which represents the sun
(Summer)
/ * / (Winter)
Summer: The tilt is toward the sun; ensures longer , more area exposure on a given day.
Winter: The tilt is away from the sun, Shorter, Less area exposure on a given day.
Spring and Fall are variants between
I Should add, The effects are opposite on the other side of the world, which is why Australia is summer during Christmas, while U.S. is Winter during Christmas
