Air Masses, Pressure, Fronts & Symbols

WATCH THIS: Meteorologist Ryan Davidson Explains Weather Maps USE YOUR NOTES: Vocabulary Matching Game 1 Use your notes to match each image or term with the correct definition. When air pressure is low, air moves up and cools forming clouds. Low pressure days might result in rain or other forms of precipitation. When air pressure is high, skies are blue and clear. Air flows down and fans out. USE YOUR NOTES: Vocabulary Matching Game 2 Use your notes to match each image or term with the correct definition. Stationary fronts occur when a cold and warm air mass meet and neither is advancing.... The front gets stuck until another air mass comes by. Warm fronts occur when a warm air mass overtakes a cold air mass. The warm air rises over the cold, forming clouds. Clouds and precipitation are a result. Cold fronts occur when a cold air mass overtakes a warm air mass. The cold air forces the warm air to rise, forming clouds. Possible storms with heavy precipitation can occur. SORTthe Weather Cards SORT the weather cards under the correct corresponding pressure system. High Pressure Low Pressure Identify this front and the kind of weather it probably will bring. Cold front; A sunny day awaits Warm front; Possible storm with heavy rain Warm front; A sunny day awaits Cold front; Possible storms with heavy rain A large volume of air that has nearly thesame temperature and humidity is called what? Front Air Pressure Air Mass Density Differences An area with high pressure will result in what possible weather? High winds High humidity and winds Clear, blue skies Rain or other precipitation A warm, moist air mass colliding with a cold air mass will result in what type of weather? Clear, sunny day Thunderstorms and heavy rain Lots of wind, but no rain light rain for a longer period of time All of the following statements are true EXCEPTfor which? Fronts are boundaries of air masses (where the air masses meet). There are always clouds at a front. One air mass can have different amounts of moisture and temperature in different parts of it. Air moves from areas of high pressure to low pressure. Air moves... from low pressure to high pressure from high pressure to low pressure always up always down What is the weather at EVERY kind of front? always tornadoes or hurricanes always sunny weather always clouds and precipitation always night What kind of pressure is ALWAYS at any kind of front? High pressure Low pressure No pressure
