A simple model of the atmospheric response to ENSO sea surface temperature anomalies

Research output: Contribution to journalArticle

Abstract

A low-order tropical atmospheric model is developed that gives a reasonable account of the tropical precipitation and circulation anomalies observed during various El Nino and La Nina events. The dynamical part of the model is a linearization about a state of rest with the usual tropical vertical mode retained. The heating is obtained from latent and nonlatent sources with the former obtained from perturbing a steady-state moisture equation about climatology and confining the heating to high SST regions. A thorough sensitivity analysis is undertaken and the model tendency to place major anomalies on the western and northern side of SST anomalies is examined. -Author
