What Is A Thunderstorm?

A thunderstorm is a storm with lightning and thunder. Its produced by a cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail. The basic ingredients used to make a thunderstorm are moisture, unstable air and lift. You need moisture to form clouds and rain. You need unstable air that is relatively warm and can rise rapidly. Finally, you need lift. This can form from fronts, sea breezes or mountains.

What Is Lightning?

Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to 100 people.

What Is A Storm Surge?

Storm surge

is an abnormal

rise of water generated by a

storm, over and above the

predicted astronomical tide.

What Does Evacuate Mean?

To remove (persons or things) from a place, as a dangerous place or disaster area, for reasons of safety or protection: to evacuate the inhabitants of towns in the path of a flood.

What is weather?

The term weather describes the state of the atmosphere at a given point in time and geographic location. Weather forecasts provide an estimate of the conditions we expect to experience in the near future and are based on statistical models of similar conditions from previous weather events.

Why is a weather forecast important?

Knowing how to recognize threatening weather conditions, where to get reliable information, and how to respond to this information that can save lives.

Diffrent componets of weather forecasts?

Temperature, amount and forms of airborne moisture, cloudiness and strength of wind are all different components of our weather. Sever weather events such as tornadoes,tropical storms, hurricanes, floods, lightning strikes and extremes of heat or cold can be costly and deadly.

Types Of Severe Weather..

  • Hurricanes
  • Tornadoes
  • Floods
  • Blizzards

What is a Hurricane?

A hurricane is a huge storm! It can be up to 600 miles across and have strong winds spiraling inward and outward at speeds of 75 to 200 mph. Each hurricane usually lasts for over a week, moving 10-20 mph over the open ocean. Hurricanes gather heat and energy through contact with warm ocean water. Evaporation from the sea water increases their power. Hurricanes rotates in a counter-clockwise direction and an 'eye' on the Northern Hemisphere and clockwise direction in the Southern Hemisphere. The center of the storm or 'eye' is the calmest part. It has only light winds and fair weather, when they come onto land, the heavy rain, strong winds and large waves can damage buildings, trees and cars

What is a Tornado?

A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speed of up to 300mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. Damage paths can be in excess of one mile wide to 50 miles long. In an average year, 1000 tornadoes are reported nationwide.

What Is A Flood, and a Flash Flood?

A flood results from days of heavy rain and/or melting snows, when rivers rise and go over their banks.

A flash flood is sudden flooding that occurs when floodwaters rise rapidly with no warning within several hours of an intense rain. They often occur after intense rainfall from slow moving thunderstorms. In narrow canyons and valleys, floodwaters flow faster than on flatter ground and can be quite destructive.

What Is A Blizzard?

A blizzard is a long-lasting snowstorm with very strong winds and intense snowfall. You need three things to have a blizzard; cold air at the surface, lots of moisture, and lift. Warm air must rise over cold air.
