Estimate the speed of the geostrophic wind at HOU (Houston TX) in ms^-1. Enter only the value to the nearest wholems^-1.

Use the following form for the geostrophic wind speed that is defined in Introduction.

V=g/f ?z/?x

where

V = speed (ms^-1)

g = 9.81 ms^-2?10 ms^-2(acceleration due to gravity)

f ? 10^-4s^-1(typical value of the Coriolis parameter for contiguous U.S.)

?z = change in height, perpendicular to the height contours

?x = distance over which height change occurs

Use the map scale along the lower left side of the map to measure distances ?x.
