JANUARY 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.

SSTs and sea levels continued well below normal values into the first half of January. But toward the end of the month, the Peru stations showed a sharp increase to normal or above-normal levels (no data from Ecuador, unfortunately). This included Talara leading Callao, the normal fingerprint for a strong coastal Kelvin wave. From historical inference, this is most likely due to a strong intraseasonal oscillation originating with an MJO fluctuation in the Indo-Pacific region.
