Hurricanes Formation

•  As ocean water warms, some of this water evaporates and transfers thermal energy into the atmosphere.

• The water vapor then cools and condenses to form clouds. The increase in water vapor raises the humidity, and the transfer of thermal energy raises the temperature. 

Hurricanes

• Hurricanes are large, tropical weather systems with an extremely low barometric pressure (air pressure), heavy rains, and high wind speeds.

• 
  

Air Masses

• Air Massess

  
  

• Large bodies of air

• Similiar Temperature and Moisture

• Temperature= Hot or Cold

• Moisture= Dry or Humid

Multiple Choice

What do air masses have in common ?

• Temperature & Density

• Direction & Temperature

Multiple Choice

Based on the information in the table, in which city will it most likely rain?

• W

• X

• Y

• Z

Formation of Thunderstorms

• Thunderstorms typically form near cold fronts

• They are also happen more frequently near the Equator

• This is because the cold air mass comes and pushes up the warm air mass. When the warm air rises, it cools, condenses, and forms clouds.

Multiple Choice

Why do cities near the ocean (Like Miami) get so thunderstorms?

• Uneven heating of earth creates lots of fronts that form thunderstorms

• The warm fronts that form only over tropical areas cause

  thunderstorms.

• The amount of sunshine received by coastal areas causes

  thunderstorms.

Multiple Choice

Tornadoes form when

• Two fronts diverge

• Two fronts transform

• Two fronts fronts converge

Multiple Choice

How do we characterize an air mass that forms over Water?

• Dry

• Wet

• Warm

• Cold

Multiple Choice

Hurricanes typically happen MOST in July, August, & September. Why is this true?

• This is when ocean water is warmest which hurricanes need to form

• This is when ocean water is coldest which tornadoes need to be created

Multiple Choice

High pressure will usually bring what kind of weather?

• Clear & Dry

• Cloudy & Stormy

Multiple Choice

How do we characterize an air mass that forms over near the equator?

• Wet

• Dry

• Cold

• Warm

Multiple Choice

Cold fronts typically bring in what kind of weather?

• Cooler temperatures and snow

• Warmer temperatures and storms

• Cooler temperatures and storms

• Sunny days and wind

Multiple Choice

Hurricanes form when low pressure is in the air. What else does a hurricane need to form???

• Warm, ocean water usually found near the poles

• Cold, pool water always found on land

• Warm, ocean water usually found near the equator

• Muy muy FRIO agua cerca del mantecado
