Low Frequency Modulation of ENSO and Internal Atmospheric Dynamics Research

PI: Duhong Min
Institution: Institute of Global Environment and Society
Additional Investigators: Ping Chang, Ben Kirtman
The purpose of this investigation is to understand the low frequency variability in ENSO amplitude. Recent analysis of several IPCC model simulations have shown that the simulated ENSO can be classified into two categories:

(i) those that have little asymmetry between warm and cold events (i.e., Gaussian) and
(ii) those that have a clear skewed distribution.

Furthermore, in climate change scenarios those in the second category have significant sensitivity to increases in greenhouse gas concentrations, whereas those in first category are relatively insensitive to increases in greenhouse gas concentrations (see Yeh and Kirtman 2005; GRL in press). In this analysis, we will extend the earlier work to examine how internal atmospheric dynamics impacts the changes in low frequency variability of ENSO.
