Numerical Simulation of the Tropical Atmospheric 10~20 Day Oscillation with a General Circulation Model

An atmospheric general circulation model is used to simulate the tropical 10~20 day atmospheric oscillation.The results are consistent with observations in several respects indicating that numerical experimentation may be a productive way to study this type of low frequency oscillation.Analyses of the power spectra and kinetic energy show that in the tropical atmosphere,the simulated 10~20 day oscillation is markedly distinct from the simulated 30~60 day oscillation.There are,however,differences in the structure between both oscillations in the tropical atmoshpere.The 10~20 day oscillation exhibits zonal wavenumber 2 features in addition to wavenumber 1.The flow field is less baroclinic and it tends to propagate westward at a faster rate along the equator.The influence of warm sea surface temperatures on the tropical 10~20 day oscillation is also simulated by prescribing global SSTs as observed during 1983 and comparing the results with those from an integration using observed, climatological SSTs.The simulated oscillation is found to be weaker,with a more barotropic vertical structure.
