B)  between 30 and 50 percent
C)  between 50 and 60 percent
D)  between 60 and 70 percent

Question 9

A downside of high-resolution models is that, as the horizontal spacing between grid points decreases, the number of computations increases.

Accepted Answer

A) True 
 B)False

Question 12

A type of dynamic instability known as ____________________ develops from the deepening of an upper trough as the result of high wind speeds, cold air moving southward, warm air moving northward, and a shortwave moving into a longwave trough.

Accepted Answer

baroclinic...

Question 13

Suppose that in a summer afternoon, you observe cumulus clouds with limited vertical growth and with tops at just about the same level. Your local weather forecast should be which of the following?

B)  Possible showers or thunderstorms by afternoon with gusty winds
C)  Continued clear to partly cloudy; cool night with low humidity
D)  High minimum temperatures

Question 18

These days the precise location where a tornado will form can be predicted up to seven days in advance.

Accepted Answer

A) True 
 B)False

Question 19

Because 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.
