1.
Draw the best fit straight line through the
temperature
vs. altitude sounding over the following two ranges:
2.
Calculate the slope of each straight line. The general formula for the slope of a
straight line is:
Slope = change in Y/change
in X = [Y(2) – Y(1)]/[X(2) – X(1)]
For example, in the
troposphere the calculation for this sounding would look approximately
like:
Slope = (9000 m – 900
m)/((–50 C) – (25 C))
Slope = 8100 m/–75C
Slope = –108 m/C
Note that:
·
The slope
in the
troposphere is negative (the atmosphere cools as the altitude
increases).
·
The
dimensions of
“meters per degree centigrade” make sense physically.
