Surface pressure systems tend to move in the same direction as the wind at 5500 m (18,000 ft)the 500-mb level. The speed at which surface systems move is about double the speed of the winds at this level.
a. True
b. False
Q. 2It is possible to make a short-range weather prediction based on a surface weather map.
a. True
b. False
Q. 3These days the precise location where a tornado will form can be predicted up to 7 days in advance.
a. True
b. False
Q. 4A downside of high-resolution models is that, as the horizontal spacing between grid points decreases, the number of computations increases. When the distance is halved, there are 8 times as many computations to perform, and the time (and computational expense) required to run the model goes up by a factor of 16.
a. True
b. False
Q. 5Because the many weather variables are constantly changing, meteorologists have devised atmospheric models that describe the present state of the atmosphere. These are not physical models that paint a picture of a developing storm; they are, rather, mathematical models consisting of many equations that describe how atmospheric temperature, pressure, winds, and moisture will change with time.
a. True
b. False
