Science Olympiad Meteorology Latest Update Graded A+ air mass ✔✔a huge body of air that has similar temperature, humidity, and air pressure at any given height and a source region. Remember cP, cT, mP, mT, cA continental polar (cP) ✔✔cold, dry stable air mass that forms over land continental tropical (cT) ✔✔unstable, warm, dry air mass that forms over land Winter - warm and dry Summer - Hot and dry maritime polar (mP) ✔✔unstable cold, moist air mass that forms over cold oceans -- Winter and Summer - cold and humid maritime tropical (mT) ✔✔warm, moist air mass that is formed over water Stable if in Pacific Ocean (weather is warm and humid) Unstable in Atlantic Ocean(weather is warm and humid continental arctic (cA) ✔✔very cold, very dry stable air mass front ✔✔the atmospheric phenomenon created at the boundary between two different air masses. Shown on map by colored lines with shapes cold front ✔✔forms when cold air moves under warm air whi ch is less dense and pushes air up (produces thunderstorms heavy rain or snow) Blue line with triangles pointed towards where the front is going. Everything behind line is cold. warm front ✔✔a front where warm air moves over cold air and brings drizzly ra in and then are followed by warm and clear weather. Red line with half circles pointed towards where the front is going. Everything behind the line is cold. occluded front ✔✔a front where a warm air mass is caught between two colder air masses and brings cool temperatures and large amounts of rain and snow. Purple line with half circles and triangles facing the same way stationary front ✔✔weak cold and warm air masses meet, but neither can move the other. Line with red half circles, blue triangles facing opposite directions. thunderstorm ✔✔the most common severe storm, formed in cumulonimbus clouds. 3 ingredients needed are MOISTURE, UNSTABLE AIR, AND LIFT! Can produce lightning and hail. hurricane ✔✔a severe storm that develops over tropical oceans and whose strong winds of more than 120 km/h spiral in toward the intensely low -pressure storm center (eye) tornado ✔✔a localized and violently destructive windstorm occurring over land characterized by a funnel -shaped cloud or violent rotating airextending t oward the ground from the thunderstorm. Need two different air masses clashing. weather station model ✔✔a group of symbols used to communicate weather at a given place on Earth's surface; Data includes temperature current precipitation, pressure and press ure change, dew point, etc. It is the circle with readings listed around it. Coriolis effect ✔✔The way Earth's rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left. Helps define global c irculation.
