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.

  • 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.
