Control of Saharan mineral dust transport to Barbados in winter by the Intertropical Convergence Zone over West Africa
[1] The reasons for the inter-annual variability of dust transport from the Sahara across the Atlantic are not well-understood. Here we address this issue by defining three new climate indices that capture the position and intensity of the zone of near-surface convergence over West Africa, a part of the global Intertropical Convergence Zone (ITCZ). We then relate these indices to a 38-year reco...
متن کاملA link between the double intertropical convergence zone problem and cloud biases over the Southern Ocean
The double intertropical convergence zone (ITCZ) problem, in which excessive precipitation is produced in the Southern Hemisphere tropics that resembles a Southern Hemisphere counterpart to the strong Northern Hemisphere ITCZ, is perhaps the most significant and most persistent bias of global climate models. In this study, we look to the extratropics for possible causes of the double ITCZ probl...
متن کاملEcosystem responses in the southern Caribbean Sea to global climate change.
Over the last few decades, rising greenhouse gas emissions have promoted poleward expansion of the large-scale atmospheric Hadley circulation that dominates the Tropics, thereby affecting behavior of the Intertropical Convergence Zone (ITCZ) and North Atlantic Oscillation (NAO). Expression of these changes in tropical marine ecosystems is poorly understood because of sparse observational datase...
متن کاملDynamics of the ITCZ–Equatorial Cold Tongue Complex and Causes of the Latitudinal Climate Asymmetry*
A coupled atmosphere–ocean–coastline model driven by solar radiation is advanced to understand the essential physics determining the annual cycle of the intertropical convergence zone (ITCZ)–equatorial cold tongue (ECT) complex and associated latitudinal climate asymmetry. With a thermocline depth similar to that of the western Pacific, the aquaplanet climate is latitudinal symmetric and stable...
