Information Summary
A Catalina Eddy on 10/13/95
These
western U.S. and eastern Pacific sea-level pressure pattern
superimposed on a visible satellite image, shows
a region of relatively high pressure (greater than 1032 millibars in
places) across the Pacific Northwest and northern Rocky Mountains. This
high pressure center ultimately was responsible for driving winds from
the north/northeast across the east-to-west mountain ranges just east
of Pt. Conception, which led to the formation of the Catalina eddy. (See
summary of information about the western U.S. overview
for more information about this companion image.)
(A note on data shown: The 8:00 A.M. and 10:00 A.M. images show buoy
data actually recorded an hour before the the land-based SAO data and
the satellite image shown. This was done because little or no buoy data
was available at 8:00 A.M. or 10:00 A.M., and because the basic pattern
probably hadn't changed so dramatically that the buoy data wouldn't be
roughly representative of the time actually claimed for it.)
