Row 1, Col 1 Cumulonimbus/warm air rises rapidly Thunderstorms form in what type of clouds? What atmospheric conditions are needed for this storm to form? 1,2 meteorologist A scientist who studies the weather is a.. 1,3 0 and 32 At what temperature would precipitation change from rain to snow? 1,4 Maritime Polar/Cool and humid What type of air mass would form over the North Atlantic Ocean? What would its temp. and humidity be like? 2,1 Kansas, Oklahoma, Texas Name 3 states that are part of Tornado Alley 2,2 Temp, clouds, storms, barometric pressure Name 4 types of information that weather satellites collect? 2,3 Precipitation and temperature, nearness to large body of water, ocean currents What are the 2 main factors that influence climate? Name two factors that affect Boston 2,4 Westerlies /Jet Stream Name two winds that move air masses in the United States 3,1 Barometer/Psychrometer, anamometer What instrument is used to measure air pressure? RH%? wind speed? 3,2 Balloons, satellites, computers, weather station models Name 3 technological tools used in gathering weather data and improving accuracy of weather forecasts. 3,3 Dry or desert Name climate region that is most likely in an area located in the interior of a large continent, on the eastside of a major mountain range, with prevailing blowing from west to east 3,4 Direction of their winds/ wet, cloudy A major difference between cyclones and anticyclones is.. What type of weather is a cyclone generally associated with? 4,1 X-CP/Y MT Use the standard two-letter air mass symbols to identify air masses X and Y. Name one safety precaution that should be taken to avoid possible injury from this tornado? 4,2 Equal pressure, mb or inches of mercury/ barometer What is an isobar? Name one unit used to measure air pressure and the instument that does it 4,3 Greenland, Antartica Name a place in the polar region that has a ice cap. 4,4 Cold/Warm/StationaryOccluded..stationary Name the four types of fronts What type of front(s) would be responsible for several days of rain and clouds? 5,1 Wind What is one of the most deadly parts of a hurricane, tornado, and snow storm? 5,2 Daytime land heat up faster than ocean, cool air above ocean replaces the air rising of land Why do sea breezes occur in Boston? Explain when and why 5,3 Unequal heating of land and water. Why are they needed in Thailand and/or India? What causes the monsoons to form? 5,4
