Question

The accompanying map is a simplified surface weather map for
April 2, 2011, on which the centers of three pressure cells are
numbered.
a. Which of the pressure cells are anticyclones (highs), and
which are cyclones (lows)?
b. Which pressure system has the steepest pressure gradient
and, hence, exhibits the strongest winds?
c. Refer to Figure 6.2 to determine whether pressure
system 3 should be considered strong or weak.
