Q

Air Mass

A
  • a large body of air that takes on the characteristics of the area over which it forms.
  • formed when air stays over an area for a long period.

Q

Air mass movement

A
  • as air mass moves, it begins to change
  • this is call a Air Mass Modification
  • helps predict weather

Q

Front

A
  • The boundary between two air masses when they collide.

- the arrival of a front indicates a change in weather

Q

Cold front

A
  • Forms when a cold air mass meets and displaces a warm air mass.
  • because cool air is denser, it moves under the warm air, forcing it up quickly.

Q

Warm front

A
  • occurs when warm air meets and overrides as a cold mass

- The less dense warm air moves over the cold air and gradually replaces it

Q

Stationary front

A
  • Formed when a warm air mass and a cold air mass meet and neither moves.
  • Tend to occur only when there is little difference in the temperature of air masses
  • The weather produced is similar to a warm front

Q

Occluded front

A
  • forms when a fast moving cold air mass overtakes a slow warm front
  • The warm air is forced up as the 2 cold air masses collide
  • Lead to cool temperatures and large amount of precipitation

Q

*Weather in the a Atmosphere

A

Water exists in the atmosphere as a solid, liquid or gas

  • Solid: snow, sleet, hail
  • Liquid: clouds, rain
  • Gas: water vapor

Q

The water cycle

A
-The water cycle is the continuous movement of water in the earth's atmosphere.
3 major steps: 
1.evaporation
2.condensation
3.precipitation
16
Q

Evaporation

A

the process of water changing from a liquid to gas.

-Earths oceans, because they are so large, provide the greatest source of evaporating water

17
Q

Condesation

A

the cooling of water vapor, turning it back into a liquid

18
Q

Precipitation

A
  • The tiny water droplets in clouds combine with one another

- Precipitation is any solid or liquid form of water that falls from clouds

19
Q

Groundwater

A

the water that is absorbed by the earths surface

20
Q

Runoff

A

happens when water falls on land and is not absorbed

21
Q

Humidity

A
  • the amount of water vapor in the air.

- The more water evaporates into the air, the higher humidity gets

22
Q

*Formation of a cloud

A
  • Water vapor rises and the air cools, it can now hold less gaseous water vapor.
  • the air cools to a temperature, called Dew Point
  • When the air reaches the dew point, water begins to condense around small dust or salt particles
23
Q

Cirro

A

(Height) high clouds, with bases above 6,000 m

24
Q

Alto

A

(Height) middle clouds with bases between 2,000 and 6,000 m.

25
Q

Strato

A

(Height) low clouds, below 2,000 m

26
Q

Cirrus

A

(Shape) latin for hair, wispy stringy clouds

27
Q

Cumulus

A

(Shape) Latin for pile or heap, puffy looking clouds

28
Q

Stratus

A

(Shape) Latin for layer, featureless sheets of clouds

29
Q

Nimbus

A

(Shape) Latin for cloud, low gray rain clouds
