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.

Late November saw a rise in sea level at Callao and two weeks later came a
2+C anomalous warming at Talara, and in the last week of December the warming
reached Callao. We have learned, however that even with almost 2 months of
2+C conditions offshore, Guayaquil has still seen no rain, unusual for the
warm season.
