Temperature increases Temperature decreases 6) Density Increases Pressure Decreases Density Decreases Pressure Increases Match each phrase on the left with two different phrases on the right. 7) Wind always moves from an area of ________ to _________ pressure. 8) It is 45 degrees in Angier, and 48 degrees in Lillington. Which town’s atmospheric conditions allow for more water to be present in the air? 9) ________ ________ is the temperature at which air must be cooled to reach saturation, or condensation. 10) ____________ is the most important phase change in driving atmospheric processes, when water vapor becomes a liquid once more. 11) Put the following in the numbered order in which they occur in cloud formation. ________ coalescence occurs, making larger rain droplets ________ condensation occurs on dust particles, creating clouds ________ warm air rises ________ LCL is reached ________ precipitation occurs, causing a downdraft of air that completes convection cycle 12) Circle the following two characteristics that would allow for the most severe hurricane. Warm ocean water cold air masses warm air masses cold ocean water 13) Tornadoes and hurricanes have which of the following options in common? a) Both typically form where air masses meet b) Both typically form from within high pressure systems c) Both often begin with thunderstorm formation 14) It is raining today in the Mojave Desert. Am I describing weather or climate and why? 15) An air mass is a large parcel of air that has similar ______________ and _____________. Air Mass Temperature? (hot or cold) Water Content? (moist or Forms over? (water or land) dry) Maritime Polar Continental Tropical Continental Polar Maritime Tropical 16) Complete the above chart by filling in blanks with the words hot, cold, moist, dry, land, water 17) The ____________ effect is caused by the Earth’s rotation and accounts for the global wind systems in our atmosphere. Objects are deflected to the _____ in the Northern Hemisphere. 18) Label each type of wind system (prevailing westerlies, polar easterlies, trade winds) according to their appropriate range. Draw arrows in each range indicating the wind direction. 60 degrees 30 degrees 0 degrees 19) A ____________ is the boundary between two air masses. 20) In the column on the left, write the letters representing the phrases on the right that correspond to the appropriate fronts. Cold A. warm air moves into cold air Stationary Warm B. several days of precipitation Occluded C. warm air is forced violently upward D. cold air moves into warm air E. rapid rate of condensation F. creates few clouds and longer, relatively weak rain showers G. creates clouds, and short, heavy rain and thunderstorms H. cold front wraps around a warm front I. warm air gently rises over cold air J. slower rate of condensation 21) Draw the map symbols used to indicate each of the four different types of fronts. Be sure to use the correct shapes and indicate appropriate colors. Draw the cold and warm fronts moving east. Draw the occluded front moving north. 22) Complete the following table.
