FEBRUARY 2008

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.

Thanks to another intraseasonal Kelvin wave pulse arriving at the end of February, coastal SSTs and sea levels are once again rising from negative anomalies toward normal along the Peru coast. With warmer water upwelling near the coast, cooler water still offshore, and the onshore winds typical of the rainy season, Ecuador can probably expect continued unstable atmospheric conditions through March.
