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 Climate Weather Day to day (shorter time) Both weather and climate deal with the condition of the atmosphere. Years (longer time) 1. What is the major difference between weather and climate? A. air temperature B. air pressure C. humidity D. time 2. Which of the following is an example of climate? A. The current temperature in Durham, NC B. The relative humidity in the field. C. The average current temperature in a region D. The average temperature in Winston Salem, NC over the past 30 years 3.Decribe the 4 different types of air masses. Polar air mass Cold air coming from the North, North East, NW 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. Pacific Northwest, near the pole Maritime Polar Canada Atlantic Northeast, near the pole Continental Cold region because of its nearness to Maritime Polarthe North pole. Polar (cold and dry) (cold and humid ) (cold and humid) Pacific near the equator Maritime tropical Continental tropical Maritime tropical or hot and region because of(warm its and humid ) dry ) (warm and humid Warm ) (warm Pacific South West nearness to the equator. Mexico Gulf of Mexico 5 Type of Air Masses Type of Air ( warm or cold, dry or humid) Source ( Mexico, Pacific, Atlantic, Gulf ) 1. Continental tropical (cT) 2. Maritime tropical (mT) 3.Continental polar (cP) 4. Maritime polar (mP) 5. Arctic (A) Warm and Dry Mexico Warm and humid Cold and Dry Pacific and Atlantic near the equator Canada and Alaska and Arctic Cold and humid Pacific and Atlantic near the Arctic cold and dry Arctic region 5. Which type of heat transfer moves warm water away from the equator? A. conduction B. convection C. radiation D. inversion Weather front A weather front is a place where air masses meet. Cold air mass Weather Front Results to Changes in Weather. Warm air mass Cold front A weather front is a place where air masses meet. Results to Cold thunderstorms, airtornado, storms mass Warm air Weather Front mass Warm front A weather front is a place where air masses meet. Results to Warm mild to moderate air precipitation mass Cold air Weather mass Front 6. How are hurricanes and tornadoes related to air masses? A. They form where air masses meet. B. They form where air pressure is the same. C. They form where air temperatures are the same D. They form within air masses. 7. What are the four types of fronts and the type of weather they bring? Warm Front Cold Front Stationary Front Occluded Front Less violent weather (light to moderate precipitation) Most violent weather. Thunderstorms and tornadoes. Causes flooding due to continuous rain. Characterized by storms, strong winds and heavy precipitations. Movement of Fronts Raleigh Winston Salem Warm Front Movement of Fronts Cold Front Winston Salem Raleigh Northern Pacific Ocean Northern Atlantic Ocean Western Pacific Ocean Southern Pacific Ocean Indian Ocean Southern Atlantic Ocean 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 form and 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? Light moderate rain NC Texas violent weather, thunderstorm 10. What kind of weather will they have in North Carolina and Texas? Light moderate rain NC Texas violent weather, thunderstorm Coalescence
