• What kind of weather comes with a low pressure system? • What instrument measures air pressure? • What instrument measures relative humidity? (Hint: Our recent lab activity.) • If the barometer reading falls, what do we know about the weather? • What will warm, moist air moving over a mountain range do? • What do we call precipitation that falls through freezing air close to the ground? • If enough energy is absorbed by liquid water, what happens to the water? • What kind of storms do cold fronts produce? • What kind of storms do warm fronts produce? • When warm air moves into cold air, that is called a . . . • When cold air moves into warm air, that is called a . . . • Describe what happens during a cold front. • How do winds in the Northern Hemisphere move in a low pressure system? • How do winds in the Northern Hemisphere move in a high pressure system? • The most severe thunderstorms are caused by . . . • What determines the type of air mass that forms? • What makes areas by the ocean warmer in winter and cooler in summer, compared to inland areas? • What happens when an air mass moves upward quickly? • What does “nimbo-” or “-nimbus” (as in cumulonimbus clouds) mean? • What kind of clouds bring thunderstorms and/or hail? • Why are weather satellites better than ground instruments? • What information can Doppler radar give us? • What do meteorologists make from their computer data to help them forecast the weather? • What are you measuring when you collect data such as air pressure, humidity, temperature, etc.? • How does Doppler radar save lives? • How does Doppler radar measure snow or rain? • What do all the weather stations, world-wide, do with the information they collect? • High pressure equals . . . • High pressure equals . . . • Low pressure equals . . . • Low pressure equals . . . • How does a hurricane form? • Why do the mid-central United States have more tornadoes? • True or False: A tornado travels a predictable path if it touches down. • Why do hurricanes develop over oceans? • What is an “anticyclone”? • In the United States, what direction do air masses move? (Hint: Same as wind.) • Look at this weather map. What do the “L” and “H” indicate? • What do meteorologists use on a weather map to convey information? • What is this air mass called and which way is it moving? • What is this air mass called and which way is it moving? • What is this air mass called and which way is it moving? • What is this air mass called and which way is it moving? • What will temperatures in Chicago be like in the next few days?
