  • 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.

  • 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.

  • Q: How are seasons formed?

    A: According to the National Weather Service, seasons are cause by the Earth's axial tilt, which is 23.5 degrees off the vertical. During various points in its orbit, the planet's north pole points toward or away from the sun to an extent. When it points toward the sun, the northern hemisphere receives more direct sunlight, and when it points away, the hemisphere receives less energy from the sun, causing the seasons.
