TEMPERATURE ON WEATHER MAPS
1.
Construct isotherms on the map below using a 10 degree Fahrenheit interval.
Temperature Gradient = Change in temperature/Distance
2.
3.
Calculate the temperature gradient between Galveston and Kansas City in oF/mi.
Show all work.
G = change in Temp = 10o F = 0.014o F/mi.
Distance
700 mi
Calculate the temperature gradient between Cincinnati and Chicago in oF/mi.
Show all work.
G = change in Temp
Distance
4.
=
20o F =
250 mi
0.014o F/mi.
0.08o F/mi.
0.08o F/mi.
Describe how you can identify a high gradient or a low gradient by looking at the pattern of the isotherms.
The closer the spacing between isotherms, the larger the gradient.

5. Using the map below, construct an isotherms using an interval of 10o F, starting with the 40o F isotherm.
6. Calculate the temperature gradient between cities X and Y. Round your answer to the
nearest hundreth.
