Structure of Large Mid-Latitude Weather Systems

True or False Quiz

Choose the best answer.


1	An anticyclone (high pressure area) will strengthen when low-level divergence exceeds upper-level convergence.
		A)	True
		B)	False


2	The prevailing westerly wind in the mid-latitude (temperate) region of the world is attributable to the distribution of temperature (cold air over the polar regions, warm air over the tropics).
		A)	True
		B)	False


3	Geostrophic flow most closely approximates the real wind in the lower troposphere, where the effect of friction is greatest.
		A)	True
		B)	False


4	Upper-level jet streams typically form as the result of strong temperature gradients in the horizontal and vertical directions.
		A)	True
		B)	False


5	The Coriolis force is an apparent force that arises from a rotating earth, which has no effect on wind speed.
		A)	True
		B)	False


6	When considering two parcels of air of identical mass, a parcel of cool air will have greater volume (i.e., take up more space) than the warm parcel.
		A)	True
		B)	False


7	As an area of low pressure (cyclone) approaches a particular area, the weather in that region often becomes clear due to rising air.
		A)	True
		B)	False


8	Gravitational attraction between two objects is inversely proportional to the distance between them.
		A)	True
		B)	False


9	If the atmospheric pressure is lower to your west and higher to the east, the resulting geostrophic wind will blow from south to north.
		A)	True
		B)	False


10	The pressure gradient force acting in the vertical direction is less than that acting in the horizontal direction, making hydrostatic balance easy to achieve.
		A)	True
		B)	False
