Abstract

In this paper are analyzed the anomalies that produce the phases of the Arctic Oscillation in the frequency of cold fronts that arrive to the western region of Cuba during the winter season in the period 1980-2011. Chronologies of cold fronts from Forecast Center of the Institute of Meteorology of Cuba, the databases from the Climate Prediction Center of the United States and the Pearson’s correlation coefficient were used. The carried out study allowed to reveal that during the negative phase of the Arctic Oscillation increases the frequency of cold fronts, especially those of classic type and moderate intensity, while during the positive phase the opposite happens. Finally, the influence of the event El Niño/Southern Oscillation (ENSO) is analyzed in the behavior of the cold fronts. This analysis allowed to reveal that during El Niño always positive anomalies of cold fronts are registered, which are larger when the Arctic Oscillation is in the negative phase, while during La Niña almost always negative anomalies are registered.
