The seasonal cycle over the tropical Pacific simulated by eleven coupled ocean-atmosphere general circulation models (GCMs) is examined. Each model consists of a high resolution ocean GCM of either the tropical Pacific or near-global oceans, coupled to a moderate or high resolution atmospheric GCM, without the use of flux correction. The seasonal behavior(More)
The question of whether and how tropical Indian Ocean dipole or zonal mode (IOZM) interannual variability is independent of El Niño–Southern Oscillation (ENSO) variability in the Pacific is addressed in a comparison of twin 200-yr runs of a coupled climate model. The first is a reference simulation, and the second has ENSO-scale variability suppressed with(More)
In this study, the processes affecting sea surface temperature variability over the 1992–98 period, encompassing the very strong 1997–98 El Niño event, are analyzed. A tropical Pacific Ocean general circulation model, forced by a combination of weekly ERS1–2 and TAO wind stresses, and climatological heat and freshwater fluxes, is first validated against(More)
The mechanisms leading to El Niño onset and termination in the ECHAM4/OPA coupled GCM are assessed and compared to observations and existing ENSO paradigms. At the equator as well as off equator, the patterns and timing of modeled El Niño composites are in good agreement with those observed. Heat content of the west Pacific is confirmed as a precursor to(More)
In a previous study, the effect of the March 1997 Westerly Wind Event (WWE) on the evolution of the tropical Pacific Ocean was studied using an ocean general circulation model (GCM). The response was characterized by (i) a cooling of the far western Pacific (ϳ0.8ЊC), (ii) a rapid eastward displacement of the warm pool (2000 km in a month), and (iii) a weak(More)
BACKGROUND The efficacy and safety of sublingual immunotherapy (SLIT) in patients with chronic rhinitis related to sensitization to house dust mites are still controversial. METHODS After application of an anti-mite mattress cover, patients were only included in the study when the cumulative symptom score over a fortnight was greater than 70 out of a(More)
Two ten-members ensemble experiments using a coupled ocean-atmosphere general circulation model are performed to study the dynamical response to a strong westerly wind event (WWE) when the tropical Pacific has initial conditions favourable to the development of a warm event. In the reference ensemble (CREF), no wind perturbation is introduced, whereas a(More)
[1] In the present study, we use a coupled model to evaluate the effect of shallow salinity stratification on the sea surface temperature (SST) and on the monsoon onset in the southeastern Arabian Sea (SEAS). A 100-year control experiment shows that the coupled model reproduces the main climatic features in this region in terms of SST, precipitation and(More)
