GY 101 UA Final (test 3) 100% Correct | Verified | 2024 Version How are air masses named? - Moisture Temperature What is required for the formation of an air mass? - Flat terrain Light winds What happens when air masses move? - Their properties change Where do air masses form? - Low and high latitudes Near the poles and near the equator Where do air masses interact? - In the middle latitudes How does Lake Effect snow happen? - Cold air mass passes over liquid water and then over cold land Name that Front: Cold, dry, stable air is replacing warm, moist, unstable air. Moves fast with showers along the leading edge - Cold Front Name that Front: Warm, moist, unstable air is replacing the cold, dry, stable air by overrunning it. The overrunning front rides up over the cold air creating widespread cloudiness and light to moderate precipitation well ahead of the front - Warm Front Name that Front: Essentially no movement, winds blow parallel to the front in opposite directions on both sides - Stationary Front Name that Front: When a cold front catches up to a warm front - Occluded Front What are the 4 mechanisms that can force air to rise? - Convection, Convergence, Orographic and Frontal lifting Which type of front is associated with heavy precipitation? - Cold Front What are the 4 life cycle stages of a middle latitude cyclone? - Cyclogenesis Open wave formation Occluding Dissipation What are the 4 types of thunderstorms? - Single Cell Multi Cell Squall Line Supercell What are the 3 stages of ordinary thunderstorm development? - Cumulus stage Mature stage Dissipating stage What is the key ingredient for the formation of severe thunderstorms? - Wind shear Sand storms created by downdrafts of air from a thunderstorm - Haboobs What shape does a Mesoscale Convective Complex (MCC) have? - Circle Why is Tornado Alley well suited to tornado development? - The meeting of different air masses over flat warm land with wind shear from the jet stream What do meteorologists look for on the radar as an indication of tornado development? - Hook Echo True or False The Fujita Scale for classifying tornados is based on Wind Speed - False - Total Damage True or False Multiple vortices can occur in a single tornado - True What is the spinning column of air that can spawn
