El Niño–Global Atmospheric Oscillation as the Main Mode of Interannual Climate Variability
The interannual variability of the global mean monthly anomalies of near-surface air temperature, sea-level pressure, wind speed near the surface, amount of precipitation and total cloudiness was investigated. The amplitudes of the anomalies of these hydrometeorological characteristics between oppos...
