Through
cooperative arrangements with South American institutions, the TOGA
program has maintained a network of nine tide stations and four
meteorological stations in Ecuador, Peru and Chile since the mid
1980's. The stations are maintained by NOAA/AOML and the University of
Hawaii. The hourly data are transmitted to down-link stations via the
GOES satellite in real time and processed. The five-day averages
(pentads) at critical stations give us an effective means of monitoring
coastal conditions with good time resolution and compact data volume.

The main feature in March is the strong positive intraseasonal
pulse in SST and sea level at Talara and Callao. The sea level
peaked on March 9 and the temperature shortly after on March 14.
This was the second of two strong pulses, the first one peaking
in late January. These events may have contributed to the contemporaneous
warming seen in SST maps along the South American coast.
