Clouds and WeatherWhat kind of weather can be predicted from each type of cloud?

Clouds

Page 5: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Rain GaugeThe rain gauge, measuring in centimeters, collects ten times the actual depth of rain that falls.

Precipitation

Page 6: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Water DropletsCloud droplets condense to become larger droplets.

Precipitation

Page 7: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Freezing PrecipitationWhat would be the air and ground temperature ranges for each type of precipitation?

Precipitation

Page 8: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Air Masses and Their Movements

Types of Air MassesAir masses can be classified according to temperature and humidity.

Page 9: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

North American Air MassesAir masses can be warm or cold, and humid or dry.

Air Masses and Their Movements

Page 10: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Types of FrontsWhat type of weather is brought by each front?

Air Masses and Their Movements

Page 11: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Cyclones and AnticyclonesWhich image is a cyclone and which is an anticyclone? What is the air motion direction of each?

Air Masses and Their Movements

Page 12: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Air Masses and Their Movements

Which circles are low-pressure centers and which are high-pressure centers?

Page 13: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Lake-Effect SnowAs cold, dry air moves across the warmer water, it becomes more humid as water vapor evaporates from the lake surface. When the air reaches land and cools, lake-effect snow falls. Which cities receive lake-effect snow?

Storms

Storms

How Thunderstorms FormA thunderstorm forms when warm, humid air rises rapidly within a cumulonimbus cloud. What is indicated by the blue and red arrows?

Storms

HurricaneWhere is the eye of the hurricane? Where are the strong and weak areas?

Page 16: Table of Contents Clouds Precipitation Air Masses and Their Movements Storms Predicting the Weather Weather Patterns

Storms

Hurricane strength is ranked on the Saffir-Simpson Hurricane Scale.

Storms

Tornado FormationAbout 1,200 tornadoes occur in the United States every year. Weather patterns on the Great Plains result in a “tornado alley.”

Predicting the Weather

Red SkyMany people use creative thought to summarize their own observations of weather.

Weather Map SymbolsThe tables below show what various weather symbols represent.

Predicting the Weather

Newspaper Weather MapThe symbols on this map show fronts, high- and low-pressure areas, the high and low temperature readings for different cities, and precipitation. The color bands indicate different temperature ranges.
