How does the earth's orbit effect the weather?

Question

Luke Allen · Accepted Answer

Sunlit hemisphere of the spinning Earth oscillates up and down the ecliptic, with period one year, due to the inclination 23.4 deg inclination of the polar axis to the normal of the Ecliptic.

The Earth revolves around its polar axis on a daily basis and orbits the Sun once every year. The Earth's overhead-Sun-midday location is obviously not fixed; it is in motion, and as a result, the sunlit hemisphere is also changing. Latitude-wise, the Earth's center oscillates between 23.4 deg S and 23.4 deg N. These aspects of the Earth's orbital motion, as well as the inclination of the spin axis, are principally responsible for the variations in weather and climate.

undefined The distribution of solar energy received by the Earth is the primary mechanism by which the Earth's orbit around the Sun influences weather patterns. This impact is observed in several key ways: 1. **Seasons**: The Earth's orbit is elliptical, and its axis is tilted relative to its orbital plane by about 23.5 degrees. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the seasons. The Northern Hemisphere experiences summer when it is tilted toward the Sun, with longer daylight hours and more direct sunlight, producing warmer temperatures; the Southern Hemisphere experiences the opposite.
