Figure 13: Time series of annual normalized tropical cyclone damage for
the U. S. East and Gulf Coasts. The long-term (1950-90) average of
$3.5 billion per year (solid line) as well as a five year running mean
(light curve) are
superimposed on the time series. Damage is
normalized to 1996 dollars by inflation, coastal county population
changes, and an index of personal property amounts.
