Weather Seasons

A:

Jet streams, which are rapidly moving ribbons of air 6 to 9 miles above the Earth, influence the weather by separating warm and cold air and pushing weather systems around the globe. The movement of a jet stream affects temperatures and precipitation. Meteorologists describe jet streams as resembling rivers in their flow.

  • What are the months for each season?

    Q: What are the months for each season?

    A: In the Northern Hemisphere, spring covers March, April and May; summer covers June, July and August; fall covers September, October and November; and winter covers December, January and February. There are no official allocations of the four seasons, though, and in the Southern Hemisphere, the seasons are reversed. When it's summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and when it is spring in the Northern Hemisphere, it is fall in the Southern Hemisphere. Many countries south of the equator, however, tend to have more tropical climates in which the evolution of the seasons is less evident.

  • Why does it hail in the summer?

    Q: Why does it hail in the summer?

    A: Hail occurs in the summer when strong thunderstorm updrafts carry raindrops high into the atmosphere, where temperatures are below freezing, according to the Atmospheric Sciences Department of Texas A&M University. This causes the water to freeze into pellets of ice, forming hailstones. These pellets may rise and fall multiple times in the storm before falling to the ground, resulting in hailstones of varying sizes.
