Tropical Pacific Drifting Buoys
M. S. Swenson / AOML, Miami
At the end of February, the number of drifting buoys reporting from the tropical
Pacific had declined to 180, of which 71% had confirmed drogues. Coverage is
particularly sparse over the near-Equatorial regions of the east and central
Pacific, but there is some evidence that the SEC on the equator at 95W has
reversed. The SEC in the western Pacific has reestablished itself.
SST anomalies at the end of the month are generally small (<0.5C) in the
equatorial band.

displacement. Red paths show buoys drogued to 15-m depth;
blue paths show undrogued buoys.
