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,
the ASP Seminar Team
