6th grade science: Weather

What is a warm front

• a front where a warm air mass is caught between two colder air masses and brings cool temperatures and large amounts of rain and snow

• front when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow)

• a front where warm air moves over cold air and brings drizzly rain and then are followed by warm and clear weather

• a boundary that separates a moist air mass from a dry air mass

What is a cold front?

• front when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow)

• The temperature at which condensation begins

• very cold, very dry stable air mass

• A boundary between air masses that don't move possibly causing rain for several days

What is a stationary Front?

• unstable cold, moist air mass that forms over cold oceans--

  Winter and Summer- cold and humid

• very cold, very dry stable air mass

• unstable, warm, dry air mass that forms over land

  Winter - warm and dry

  Summer - Hot and dry

• A boundary between air masses that don't move possibly causing rain for several days

What is an occluded front?

• brings cool temperatures

• a front where a warm air mass is caught between two colder air masses

• Brings clear weather

• brings drizzly rain

• brings large amounts of rain and snow

What is a front?

• A huge body of air that has similar temperature, humidity, and air pressure at any given height

• When any two air masses meet. The four major types are cold fronts, warm fronts, stationary fronts, and occluded fronts.

What is a continental polar (cP) air mass?

• An air mass that is cold

• An air mass that is warm

• An air mass that forms over water

• An air mass that forms over land

What is a maritime polar (mP) air mass?

• unstable cold, moist air mass that forms over cold oceans--

  Winter and Summer- cold and humid

• Wet and warm air mass

• hot and humid air mass that originates from the ocean region straddling the equator.

• very cold, very dry stable air mass

What is a maritime tropical (mT) air mass?

• dry air mass

• Wet and warm air mass that forms over water

• unstable, warm, dry air mass that forms unstable, warm, dry air mass that forms over land

  Winter - warm and dry
