Naming fronts
NAMING FRONTS atmosphere.  Which occurrence is

  • The type of front depends on both the direction in which the air mass is moving and the characteristics of the air mass.


Cold front
COLD FRONT atmosphere.  Which occurrence is

  • The cold air mass is replacing the warm air mass.

  • The air behind a cold front is colder and typically drier than the air ahead of it


Warm front
WARM FRONT atmosphere.  Which occurrence is

  • A cold air mass is receding.

  • Favors the development of widespread, continuous precipitation


Stationary front
STATIONARY FRONT atmosphere.  Which occurrence is

  • A front that is not moving.

  • Stationary fronts can also produce significant weather and are often tied to flooding events


Occluded front
OCCLUDED FRONT atmosphere.  Which occurrence is

  • Cold fronts move faster than warm fronts.

  • Sometimes in a storm system the cold front will "catch up" to the warm front.

  • Which ever air mass is the coldest undercuts the other.

    • an average of the atmospheric conditions in an area over a long period of time.

    • the current conditions of the atmosphere at a certain time and place.

    • an average of the atmospheric conditions in over a short period of  time.

Thurs. 5/16 and Fri. 5/17 atmosphere.  Which occurrence is


  • Why might a meteorologist compare a new weather map to one that is a day old?

    • The weather conditions yesterday can accurately predict what type of weather will occur today.

    • A comparison of the maps can help determine how fast fronts are moving.

    • Meteorologists never compare current weather maps with day old maps.

    • If an area experienced precipitation one day, it will experience precipitation the next day.

Using a double bubble map, compare and contrast absolute and relative humidity.


Humidity
Humidity can be held

  • Humidity is the amount of water vapor in the air. Warmer air can hold more water vapor than colder air and usually has a higher humidity. Absolute humidity is a measure of the actual amount of water vapor in the air. For example, the very moist air of the tropics might have 18 g of water for every 1 kg of air, giving an absolute humidity of 18g/1 kg. While drier polar air may only have an absolute humidity of 1 g/kg. More often, humidity is expressed as relative humidity. This is the amount of water vapor in the air compared to the amount of water vapor the air could potentially hold. Thus, it is expressed as a percent. For example, at 25o C, air would be 100% saturated if in held 20 g of water. This would be 100% humidity(20g/20g). If this air held only 5g of water it would have 5g/20g or 25% relative humidity.
