A diagnostic study of recurrent meteorological anomalies in a 15 yr simulation with a GFDL general circulation model.

Abstract

The spatial structure and temporal characteristics of prominent anomalies occurring in a 15 yr simulation with a GFDL spectral general circulation model are examines using empirical orthogonal functions, teleconnection patterns, composite charts, lagged correlation functions and frequency spectra. The principal anomaly pattern in the Northern Hemisphere summer is relatively less organized, while those for the Southern Hemisphere and the tropics are noted for their zonal symmetry. The east-west sea level pressure seesaw associated with the observed Southern Oscillation over the Pacific is not simulated by the model.-from Author
