Abstract

Resultant winds over the Pacific are derived from an Advanced Technology Satellite (ATS 1) for the month of November 1969. Since the method uses clouds as tracers, these resultant winds are biased toward cloud-producing circulation features. These biases appear to be smallest in the Tropics and, consequently, the winds here can be very useful for studies of the average circulation at low latitudes. Some of the important features of this circulation over the equatorial Pacific are clearly revealed.
