The Sverdrup circulation in the tropical Pacific observed by scatterometer winds
The Sverdrup circulation in the tropical Pacific
observed by scatterometer winds
Slides shown during talk at the Fall AGU, San Francisco, Dec 7 2002
(This is a shortened version of a longer talk on this subject,
emphasizing the scatterometer wind aspects.
Also download the manuscript accepted at JPO.)
- Why is the Sverdrup circulation so weak near the equator?
- ADCP observations:
- Johnson et al. 2001 data distribution
- (y,z) sections of zonal current at 110°W, 155°W, 165°E
- Maps of surface zonal current and zonal transport.
- Part of the answer is that the ship winds were wrong (Compare wind products):
- 6 maps of Curl(Tau)
- Zonal stress at 130°-100°W
- Maps of ERS and FSU Taux and difference: 25°S-25°N 10°S-10°N
- ERS curl and Sverdrup zonal transport (Why the strip of curl matters)
- Sverdrup streamfunction: 20°S-20°N 10°S-10°N
- Observed and Sverdrup zonal transport
Compare FSU: Sverdrup zonal transport from FSU and ERS winds Add obs transport
