1 .		The air temperature and the high dew point at station A are indicative of a ___________ air mass.
2 .		By contrast, the very different moisture content at station B suggests that station B is experiencing a _________ air mass.
3 .		The air temperature and moisture characteristics of the lower atmosphere at this station suggest that a _____________ air mass is overhead.
4 .		If you know that the normal temperature at the time of this sounding at this station is 10° C, you would probably conclude that there is presently a _____________ air mass overhead.
5 .		Compare the observed sounding for Madison, Wisconsin for a day in mid-October with the forecasted sounding for 48 hours later. What is supposed to happen over the next two days at this site?
6 .		A front travels the distance between Minneapolis and St. Louis (500 miles) in 17 hours. What is the average rate of movement of this front?
7 .		What type of front is likely to be occurring in the previous question?
8 .		A sounding (vertical cross-section) shows the following temperature and moisture conditions at the following altitudes: 5 km temp. = -5° C, Relative Humidity 50% 3 km temp.= 12° C, Relative Humidity 35% surface temp.= 40° C, Relative Humidity 15% What is the average environmental lapse rate over this 5 km layer?
9 .		Suppose a typical warm front with a slope of 1:200 is moving northward from the Gulf of Mexico. By the time it reaches St. Louis, how high would one need to rise above Minneapolis to reach the overrunning warm air?
10 .		Suppose a typical cold front with a slope of 1:100 moving southward reaches St. Louis. If a sounding at a station north of St. Louis identifies warm air displaced by the front at a height of 0.6 km, how far from St. Louis would you estimate this station is located?
