1. MAP TAP 2002-2003Weather Fronts1 Bell Work- Good morning Shinning Students! Determine if each answer is correct or incorrect and explain why. 1. The following is a process that takes place in the atmosphere: solar energy → warm air rises → air cools in upper atmosphere and sinks → air currents This process can best be identified as F wind formation. G cloud formation. H precipitation runoff. J static electricity.

10. MAP TAP 2002-2003Weather Fronts10 Cold Air Masses Most of the cold winter weather in the U.S. is influenced by three polar air masses. Continental Polar- (cP)- is an air mass that forms over northern Canada and brings extremely cold weather to the U.S. in the winter and cool dry weather in the summer.

11. MAP TAP 2002-2003Weather Fronts11 Cold Air Masses continued Maritime Polar (mP)- are air masses that form over the North Pacific Ocean and are cool and very wet. Brings rain and snow to the Pacific Coast in winter and cool, foggy weather in the summer.

13. MAP TAP 2002-2003Weather Fronts13 Warm Masses Warm Masses- there are four warm air masses that effect the weather in the U.S. Maritime Tropical (mT)- an air mass that develops over warm areas in the Pacific Ocean and are milder than mP. Other mT develop over the Guld of Mexico and the Atlantic Ocean and bring hot and humid weather in the summer, hurricanes, and thunderstorms. Maritime Polar (mP)- an air mass that forms over the Pacific ocean and brings cooler air

14. MAP TAP 2002-2003Weather Fronts14 Warm masses continued Continental Tropical- (cT)- an air mass that forms over the deserts of northeren Mexico and southwestern United States. This mass moves northward and brings clear, dry and hot weather in the summer. Continental Polar- (cP)- form over northern Canada and bring cool weather

16. MAP TAP 2002-2003Weather Fronts16 Comparing Warm and Cold Fronts Cold fronts move faster than warm fronts. Cold fronts move faster than warm fronts. The weather activity in a cold front is often violent and happens directly at the front. The weather activity in a cold front is often violent and happens directly at the front. Cold fronts have sudden gusty winds high in the air creating turbulence. Cold fronts have sudden gusty winds high in the air creating turbulence. The weather activity in a warm front generally happens before the front passes. The weather activity in a warm front generally happens before the front passes. In a warm front the cloud formation is very low often creating situations of poor visibility. In a warm front the cloud formation is very low often creating situations of poor visibility.

25. Weather Fronts25 Be a Weather Forecaster You are planning to travel to Alabama in 2 days. The high temperature there for today is 68 º F. Use the map to help you predict whether the temperature in Alabama will increase, decrease, or stay the same. Explain why you think so.

26. 26 Be a Weather Forecaster There is a cold front approaching. The temperatures will probably be cooler behind the front.

27. MAP TAP 2002-2003Weather Fronts27 Be a Weather Forecaster Of course, meteorologists (weather forecasters) use much more data than fronts and air masses to help them forecast the weather more accurately. But any forecast is just a prediction of what might happen. Even with the best data, weather forecasts can be wrong.
