Ja. Harlan et Tm. Georges, OBSERVATIONS OF HURRICANE HORTENSE WITH 2 OVER-THE-HORIZON RADARS, Geophysical research letters, 24(24), 1997, pp. 3241-3244
Hurricane Hortense was observed in the Atlantic Ocean on 12 September
1996 by two high-frequency over-the-horizon radars in Texas and Virgin
ia, looking at backscatter from the ocean surface. Dual radar coverage
permits construction of an unambiguous surface-wind-direction field a
nd a vector surface-current field with about 15-km resolution in the s
torm's vicinity. The known location of a storm band coincides with a r
egion of surface convergence indicated by the radar. The surface-curre
nt field lags the wind field by about 3 h and shows the strongest ocea
n response to the right of the storm track, with near-inertial rotatio
n in the storm's wake. Analysis of surface-wave directionality shows t
hat it depends on the recent wind-direction history at each point.
