Air Mass

What is a continental polar air mass?

• A warm and humid air mass that forms over oceans in tropical regions.

• A dry and cold air mass that forms over land in polar regions.

• A moist and warm air mass that forms over land in temperate regions.

• A dry and warm air mass that forms over deserts.

What is a maritime polar air mass?

• A warm and dry air mass that forms over land in tropical regions.

• A wet and cold air mass that forms over the ocean in polar regions.

• A hot and humid air mass that forms over the ocean in equatorial regions.

• A cool and dry air mass that forms over the ocean in temperate regions.

What is a continental tropical air mass?

• A cold and wet air mass that forms over oceans.

• A warm and dry air mass that forms over hot land areas.

• A cool and humid air mass that forms over polar regions.

• A warm and moist air mass that forms over tropical oceans.

What is an air mass?

• A small cloud formation that moves with the wind.

• A large body of air with uniform temperature and humidity characteristics that forms over a specific area.

• A weather phenomenon that occurs during thunderstorms.

• A type of air pollution caused by industrial emissions.

What role do air masses play in climate?

• They have no impact on climate.

• They only affect temperature but not moisture levels.

• They play a crucial role in climate by determining the temperature and moisture levels in a region, influencing long-term weather patterns.

• They only influence short-term weather changes.

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

• Warm

• Cold

• Tropical

• Dry

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

• Wet

• Dry

• Humid

• Tropical

What is the significance of air masses in weather forecasting?

• They have no impact on weather patterns.

• They help predict weather patterns and changes based on their characteristics.

• They only affect temperature but not precipitation.

• They are only relevant in tropical regions.

What factors influence the characteristics of an air mass?

• The source region, including temperature, humidity, and the nature of the surface (land or water).

• The altitude of the air mass and the presence of mountains.

• The time of year and the phase of the moon.

• The wind speed and direction in the upper atmosphere.

What is the difference between maritime and continental air masses?

• Maritime air masses are formed over oceans and are typically moist, while continental air masses are formed over land and are usually dry.

• Maritime air masses are formed over land and are usually dry, while continental air masses are formed over oceans and are typically moist.

• Maritime air masses are always cold, while continental air masses are always warm.

• Maritime air masses contain more pollutants than continental air masses.
