Title: Getting Rid of El Niño: Isolating its Signal With a Nonnormal Filter

When: Wednesday, November 8, 11am-12pm (refreshments at 10:30, lunch to 
follow)

Where: ML Main Seminar Room.

Abstract:

A dynamically-based filter is used to separate tropical sea surface 
temperatures (SSTs) into three components: the evolving El Nino signal, 
the global tropical trend, and the background.  The components thus 
isolated are not independent. On the contrary, this procedure allows us 
to see the importance of the interdecadal signal is to the 
predictability of El Nino. Further, this procedure allows one to observe 
signals, such as the tropical Atlantic dipole, that are usually swamped 
by the stronger El Niño and trend signals.


See you there,
