Vocabulary Causes of Weather Standards 7.E.1.2 Explain how the cycling of water in and out of the atmosphere and atmospheric conditions relate to the weather patterns on earth. 7.E.1.3 Explain the relationship between the movement of air masses, high and low pressure systems, and frontal boundaries to storms (including thunderstorms, hurricanes, and tornadoes) and other weather conditions that may result. Activator Create a myth or a story about how weather forms. Legends of Weather Prezi Or See this link for examples. Make a 5 Flap Foldable ►Take a blank piece of paper ►Look at the example of a 5 flap foldable ►Fold paper in half (lengthwise) ►Open it up and fold in the two sides to make doors ►Use scissors to cut doors ►Compare yours with the example given Directions Go ahead and get out your SISNs!!!! We have a lot to do so be ready. You need: - A pencil - Scissors - Glue stick Air mass Definition: body of air with same temperature, humidity, and pressure Example: continental, tropical, maritime, polar Picture/Visual: Source Regions Definition: The area over which air masses form. Example: cT, cP, mT, mP Picture/Visual: Continental Definition: Air masses that form over land. Maritime Definition: Air masses that form over water. Polar Definition: Air that forms in polar, cold regions. Tropical Definition: Air that forms in tropical, hot regions. High pressure Definition: whirling mass of cool, dry air that generally brings fair weather and light winds Example: sunny skies or High=Happy weather Picture/Visual: Low pressure Definition: a whirling mass of warm, moist air that generally brings stormy weather with strong winds Example: Low pressure=loser weather Picture/Visual: Front Definition: the front of an air mass. Example: cold front Picture/Visual: Cold front Definition: boundary of an advancing mass of cold air, trailing edge of a low-pressure system Example: cold air mass is replacing a warm air mass-temps decrease Picture/Visual: Warm front Definition: advancing mass of warm air, in particular the leading edge of a high-pressure system Example: moving mass of warm air- often means rain is coming Picture/Visual: Stationary Front Definition: Boundary between a warm air mass and a cold air mass that hit one another. Example: often means rain is coming Picture/Visual: Occluded Front Definition: Occurs when a warm front is located in the middle of two cold air masses. Example: often means rain is coming Picture/Visual:
