Storm Surges
q Process 1: Hurricane winds
drag surface waters forward and
pileup the waters near coasts.
q Process 2: Lower atmospheric
pressure raises sea level (for every 1 mb
pressure decrease, sea level raises 1
cm).
q Storm surges raise costal
sea level by a meter or two for most
hurricanes, but can be as much as 7
meters.
