10 questions on Air masses and front EEN 2.5.2 Eric Angat Science teacher

Essential Question: How do I explain the movement of air masses and their effect on weather?

Comparing Weather and Climate Both weather and climate deal with the condition of the atmosphere. Day to day (shorter time) Years (longer time)

1. What is the major difference between weather and climate? air temperature air pressure humidity time

2. Which of the following is an example of climate? The current temperature in Pinehurst, NC B. The relative humidity in Atlanta The average current temperature in a region The average temperature in Winston Salem,NC over the past 30 years

3.Decribe the 4 different types of air masses? Cold air coming from the North, North East, NW Polar air mass Tropical air mass Warm air coming from the South, South East, SW Maritime air mass Humid air coming from the oceans Continental air mass Dry air coming from Canada and Mexico

4. What are the common characteristics of the air masses in United States? Cold region because of its nearness to the North pole. Warm or hot region because of its nearness to the equator.

Continental Polar Maritime Polar Maritime Polar Maritime tropical Canada Pacific Northwest Continental Polar (cold and dry) Atlantic Northeast Maritime Polar (cold and humid ) Maritime Polar (cold and humid) Cold region because of its nearness to the North pole. Subtropical Pacific Maritime tropical (warm and humid ) Continental tropical (warm and dry ) Maritime tropical (warm and humid ) Warm or hot region because of its nearness to the equator. Gulf of Mexico Pacific South West Mexico

5. Which type of heat transfer moves warm water away from the equator? A. conduction B. convection C. radiation D. inversion http://oceanbowl.blogspot.com/

Results to Changes in Weather. Weather front A weather front is a place where air masses meet. Cold air mass Warm air mass Weather Front Results to Changes in Weather.

Results to thunderstorms, tornado, storms Cold front A weather front is a place where air masses meet. Results to thunderstorms, tornado, storms Cold air mass Warm air mass http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/af/frnts/cfrnt/def.rxml Weather Front

Results to mild to moderate precipitation Warm front A weather front is a place where air masses meet. Results to mild to moderate precipitation Warmair mass Cold air mass http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/af/frnts/cfrnt/def.rxml Weather Front

6. How are hurricanes and tornadoes related to air masses? They form where air masses meet. They form where air pressure is the same. They form where air temperatures are the same They form within air masses.

7. What are the four types of fronts and the weather they bring? Warm Front Less violent weather (light to moderate precipitation) Most violent weather. Thunderstorms and tornadoes. Cold Front http://comingbackalive.com/fronts.htmlhttp://comingbackalive.com/fronts.html Stationary Front changes from higher to lower temperatures Causes flooding due to continuous rain. Occluded Front Characterized by storms that are dissipating or dispersing.

8. Describe the direction of the following weather fronts? http://www.phschool.com/atschool/phsciexp/active_art/weather_fronts/

Cold front-violent weather Moves to the direction of the cold air mass Cold air mass

Warm front - light or moderate rain. Moves to the direction of the warm air mass Warm air mass

Occluded front-appears when storms disperse. Moves to the direction of the cold air mass

Stationary front- long days of rain ( flood). Stationary or does not move.

9. What kind of front is moving towards North Carolina, Chicago, and New York? Cold air mass Light moderate rain NC http://www.mv.k12.wa.us/science/integrated/athena/curric/weather/hsweathr/fronts.html Texas Warm air mass violent weather, thunderstorm

10. What kind of weather will they have in North Carolina and Texas? Cold air mass Light moderate rain NC http://www.mv.k12.wa.us/science/integrated/athena/curric/weather/hsweathr/fronts.html Texas Warm air mass violent weather, thunderstorm
