JULY 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.

The main points of interest regarding July are (1) that
the positive SST anomalies -- heretofore seen at Talara
in recent months, have now appeared at Callao, and (2)
that positive sea level anomalies at Callao have persisted
for more than two months and now exceed the typical time
scale of intraseasonal Kelvin wave surges.
