What is a hurricane?

• A rotating column of air with extremely high wind speeds of 117 km/h or higher that touches the ground

• A storm that has wind speeds of 93 km/h, hail that is at least 2.5 cm wide

• A winter storm that lasts for at least three hours with winds greater than 56 km/h and large amounts of blowing snow

• A huge, rotating, low pressure storm system that forms over warm water near the equator and has sustained wind speeds of 119 km/h or higher

Which area is more dangerous in a heat wave: Cities or the country?

• The country because they have more open space to hold more thermal enery

• The city because the buildings and concrete hold more thermal energy

How does a blizzard form?

• Surface temperatures are near or below zero. In a low pressure system, a moist warm air mass moves over a cold air mass producing strong winds and snow.

• A rotating low pressure system forms over the ocean where warm moist air rises and water condenses into storm clouds.

• Cold dry air moves over warm moist air near the ground. Water in the air condenses into storm clouds. Warm updrafts and cool downdrafts are far apart, allowing the system to grow larger.

• Surface temperatures are near or below zero. In a low pressure system, a moist warm air mass moves over a cold air mass producing strong winds and snow.

Why are there more tornadoes in the Great Plains than anywhere else in the U.S?

• The Great Plains have just as many tornadoes as other areas in the U.S

• The Great Planes have warm up drafts & cool down drafts that combine the most frequently

• The Great Plains aren't located next to any oceans

• The Great Plains have many mountains and do not have flat land formation

What things occur when a cold front meets a warm front?

• -Contains two cold air masses meet a warm air mass

  -Can bring light, mid, or heavy precipitation

• -The warm and cold front do not move and stay stationary

  -They occur over a long period of time

  - Bring no weather with them

• -The cold front pushes up and over the warm front

  -It stay in a location over a long period of time

  -brings light rain

• -The cold front pushes the warm front up over the cold air replacing the warm air

  -It occurs usually pretty quickly in an area

  -It often brings stormy weather
