Derive an expression for the geostrophic wind, expressing your answer
in vector form. Draw the geostrophic wind vector on a sketch of the
geopotential height distribution, including an indication of the scale, and
compare your answer with
Fig. 2.14.
To what accuracy is the observed
wind approximated by the geostrophic wind?
