NOTES: 16 Sep 97 -- SST Anomalies

El Nino is still the main event! 

Upwelled wakes from Hurricanes Erika [north of 
Puerto Rico] and Linda [off Baja California] reveal 
marked differences from earlier anomaly charts.  
Both "Linda", and more recently "Nora" derived 
much of their energy over some of the most robust 
positive SST anomalies ever seen off Mexico's 
Pacific coast.  

During the 82/83 El Nino, hurricanes prevailed 
throughout the fall and winter months from Hawaii 
[Iwa-Nov82] to Tahiti [in the SE Tropical Pacific 
these events established a new modern day record]; 
all this from an anomalous heat supply and a 
conducive atmosphere.

Cooler than normal waters continue around Indonesia 
and the Phillippines where drought conditions prevail 
due to El Nino.  Warmer than normal conditions in 
the northern Indian Ocean-Arabian Sea off Africa 
indicate the northward flowing Somali Current is 
extremely weak this year as upwelling [typical for 
August into October] is not in evidence.
