1 Standard sea level pressure in millibars is 2 Standard sea level pressure in inches of mercury is 3 The mercurial barometer was invented by 4 Which of these instruments is NOT used to measure air pressure? a)mercurial barometer b)aneriod barometer c)barograph d)anemometer 5 An altimeter is an adaptation of the 6 The force that generates wind is 7 Which of these factors influence the magnitude of the Coriolis force? a)wind speed b)latitude c)wind direction d)both wind speed and latitude both wind speed and latitude 8 Lines on a weather map connecting places of equal air pressure are called 9 Closely spaced isobars often indicate 10 A steep pressure gradient 11 Widely spaced isobars often indicte 12 The Coriolis effect influences 13 In the Northern Hemisphere, the winds associated with a low pressure system (cyclone) blow COUNTERCLOCKWISE and TOWARD the center 14 In the Northern Hemisphere, winds associated with a high pressure system blow CLOCKWISE and OUTWARD from the center 15 If Earth were not rotating air would move directly from high to low pressure are generally faster than surface winds 17 High air pressure systems are usually associated with a)diverging winds b)decending air c)clear weather d)all of these 18 Low air pressure systems are usually associated with 19 In the Southern Hemisphere, the winds associated with a low pressure system blos CLOCKWISE and TOWARD the center 20 If "fair" weather were approaching, the pressure tendency would probably be 21 If stormy weather were approaching, the pressure tendency would probably be 22 Most of the United States is situated in which zone of prevailing winds? 23 Another name for the area of equatorial lows is the 24 This pressure zone is associated with abundant precipitation and warm temperatures. 25 The subpolar low (polar front) is A zone where the polar easterlies and the westerlies converge 26 When are upper air winds faster? 27 A Santa Ana (or Chinook or Foehn) wind is a very dry, warm wind flowing down a mountain slope 28 A sea breeze usually originates during the day and flows toward the land 29 A land breeze usually originates during the evening and flows toward the water 30 Fast moving currents of air found near the top of the troposphere are called 31 What is the technical name for a high pressure center? 32 Low pressure systems are usually associated with clear weather 33 Cyclones are usually associated with stormy weather 34 If the barometer indicated 1020 millibars, air pressure would be considered high 35 The Coriolis effect is strongest at the equator and diminishes in strength poleward. 36 The pressure gradient force is the driving force behind wind. 37 A southwest wind blows toward the northeast. 38 An isobar is a line connecting places of equal humidity. 39 Anticyclones characteristically have winds blowing out from their centers. 40 The ultimate cause of a sea breeze is the unequal heating of land and water. 41 Horizontal movement of air is called wind. 42 A mountain breeze is best developed in the hottest part of the day. 43 The region where the trade winds meet is also called the DOLDRUMS 44 Most of the people living in the United States are under the influence of the wind belt known as the westerlies. 45 Closely spaced isobars indicate high wind speeds. 46 In the Northern Hemisphere, winds blow clockwise and outward from the center of anticyclones. |
