Simplified metrics for the identification of the MaddenJulian oscillation in models
We propose simplified metrics to evaluate the fidelity with which the Madden–Julian oscillation (MJO) is simulated in climate models. These metrics are based on lag correlation analysis of principal component time series (PCs). The PCs are obtained by projecting simulated 20–100 day bandpass filtered daily outgoing longwave radiation onto the two leading empirical orthogonal functions of observ...
متن کاملIntraseasonal variations of the tropical total ozone and their connection to the MaddenJulian Oscillation
[1] We investigate the intraseasonal (30–90 day) variations in satellite-observed tropical total ozone (O3) and their connection to theMadden-Julian Oscillation (MJO). Tropical total O3 intraseasonal variations are large ( ±10 DU) and comparable to those in annual and interannual time scales. These O3 anomalies are mainly evident in the subtropics over the Pacific and eastern; hemisphere and pr...
متن کاملTropical Atlantic Biases in CCSM4
This paper focuses on diagnosing biases in the seasonal climate of the tropical Atlantic in the twentiethcentury simulation of the Community Climate System Model, version 4 (CCSM4). The biases appear in both atmospheric and oceanic components. Mean sea level pressure is erroneously high by a few millibars in the subtropical highs and erroneously low in the polar lows (similar to CCSM3). As a re...
