What is Hail?

Hail is a form of precipitation that falls from the sky as small pieces of ice often spherical shape. The size of the ice can range from the size of a pea to the size of a grapefruit. Hail storms are damaging to crops and annually can cause over 1 billion dollars of damage!

Hail forms as a result of strong updrafts common in severe weather systems.

Hail can be very dangerous at times. Hail storms usually occur with a severe thunderstorm which can at times cause tornadoes!

  1. Based on our findings, the probabilities of events in the months of August and May can be expressed as common fractions because they are all the same. They both had one occurrence out of eleven in twenty years.

  5. The regions of the U.S. that you can expect tornadoes are East of the Rocky Mountains, the Great Plains, Midwest, Mississippi Valley, and Southern U.S. Tornadoes are most common in the Spring because this season is a transitional period for the climate, therefore there are more chances of cooler air meeting with warmer air. On the other hand, tornadoes are least common in the Winter.

    Hurricanes are expected in the Atlantic Ocean between June 1st- November 30th. In the Pacific Ocean, they begin around May 15- November 30th. This is because of a difference in water temperatures between the East and the West Coast. The East Coast provides warm water which maintains a hurricane.

    The regions in the U.S that can expect winter storms are in the East Coast and Mid West. Winter storms obtain their energy from different temperatures who have different air masses that collide.

    Floods are expected to occur anytime. They are more likely to occur in coastal areas with low laying land (Georgia, Massachusetts, North Carolina, South Carolina, Virginia, New Jersey, New York, California, Louisiana, and Florida).
