We show the space and time variability of the Florida Current in the S
outhern Straits of Florida using imagery derived from measurements mad
e with two high-frequency over-the-horizon (ionospheric) radars. Betwe
en March and August 1997, ten surface current maps show how the Florid
a Current meanders in response to mesoscale eddies propagating eastwar
d through the Straits. Satellite altimetry aids in the interpretation
of the radar imagery by showing upstream eddy development in the Gulf
of Mexico.
