Row 1, Col 1 HUMIDITY What term describes the amount of water vapor in the atmosphere? 1,2 OROGRAPHIC LIFTING Mountains acts as barriers which contribute to cloud formation. Which lifting mechanism is this? 1,3 CUMULUS What type of cloud is fluffy in appearance? 1,4 DEPOSITION The formation of frost on a cold windowpane is an example of which process? 2,1 100% / SATURATED If the wet-bulb and dry-bulb on a psychrometer read the same temperature, what does this tell us about the relative humidity of air? 2,2 FRONTAL WEDGING Cold air gets wedged under warm air, causing the warm air to rise. Which lifting mechanism does this describe? 2,3 What is the Bergeron process? The process that explains the formation of ice crystals / snow in a cloud. 2,4 WATER VAPOR What is the most important gas when it comes to atmospheric process? 3,1 THE FIRST ROOM The temperature in each of two rooms is 30 degrees C. The relative humidity in the first room is 80% and the relative humidity in the second room is 70%. The air conditioning is turned on in each of the rooms and the temperature begins to cool at an equal rate in both rooms. Which room should show condensation on its walls first? 3,2 Cloud formation Saturated air, unstable air, condensation nuclei & rising air are all necessary for the formation of… ___________________ 3,3 SLEET Snow falls through warm air then refreezes above the ground, which type of precipitation is likely to form? 3,4 CONDENSATION If water vapor in the air is cooled, which phase change will happen? 4,1 70% Use a relative humidity chart. If the dry bulb temperature is 4C and the wet bulb temperature is 2C, what is the relative humidity? 4,2 ADIABATIC heating/cooling/temperature changes When air expands, it cools down. When air is compressed, it warms. What is the name of this process? 4,3 collision-coalescence A theory of raindrop formation in warm clouds in which large cloud droplets collide and join together with smaller droplets to form a raindrop. 4,4 Evaporation then Condensation The sequence of phase changes that would convert water from the ocean into a cloud. **there are 2 5,1 36% Use a relative humidity chart. If the dry bulb temperature is 2C and the wet bulb -2C, what is the relative humidity? 5,2 WINDWARD The side of a mountain in which air rises and cools causing a lot of clouds & precipitation. 5,3 FREEZING RAIN If a cloud produces snow and the snow falls through warm air but then freezes on the surface, What type of precipitation would we experience? 5,4
