AB: The oceanic and atmospheric intraseasonal variability has been studied in global scale with emphasis on South Hemisphere through a general descriptive analysis. The possible connections of both systems (ocean and atmosphere) have been investigated. Sea surface temperature (SST), meteorological wind fields, short wave radiation and latent and sensible heat fluxes data have been statistically treated to identify and analyze the intraseasonal oscillations characteristics of the interface ocean-atmosphere. Through these determinations the ocean model response of the Princeton Ocean Model (POM) is being evaluated in global scale in the intraseasonal band. The oceanic model has been forced using superposition of wind and heat flux averages (so the surface currents and the termohaline circulation are maintained) with general characteristics of the intraseasonal anomalies. These anomalies were determined through statistic data treatment in specific periods in order to compare climatological situations with those ones forced with the presence of intraseasonal perturbations that propagate over the ocean.
