Name:Period:Air Mass Source RegionsCompare and contrast the source regions of continental and maritime air masses.How do the source regions of polar and tropical air masses differ?Which air masses influence the northwestern United States? What type of weather do these air masses bring?Which type of air mass brings cold, dry weather to the northeastern United States?Use what you have learned about air masses to explain why cool, dry summer weather in the central United States might change to hot, dry pare and contrast the influence of a maritime polar and a maritime tropical air mass.What change would air mass modification cause in a continental polar air mass that moves south over the central United States?Global Wind SystemsWhat wind systems move air from about 30° north or south latitude toward the equator?Describe the movement of air in the huge convection current between 30° north latitude and the equator.According to the diagram, what forms as a result of rising air at the equator? How might this account for the formation of tropical rain forests at the equator?What wind systems move air from about 30° to 60° north or south latitude?Describe the movement of air in the huge convection current between 30° and 60° south latitude.Would you expect high or low air pressure at the poles? Explain your answer.What wind systems move air from about 60° north or south latitude to the poles?List the 4 types of fronts found on the weather map below. Describe each front and describe what direction the front is moving in (north, south, east, west)Front TypeDescribe the Front (cold, warm, stationary)Direction Front is movingWeather ExpectedWhat type of weather will occur in the high pressure locations? ________________________________ _________________________________________________________________________________________________________What type of weather would occur in the low pressure locations? _____________________________ _________________________________________________________________________________________________________-651510-1807630037020507620-358775457208483606985767080520703856355457201.
