Asymmetry of the Intertropical Convergence Zone it is the equatorial upwelling that prevents the ITCZ being created at the equator. To explain this simply, upwelling brings cold water to the surface, which will cool the above atmosphere and make it stable because of relative high air density due to low temperature. Thus, this area of the equator is different compared to the strong vertical convection and abundant precipitation of the ITCZ. As a result, the SST is latitudinally asymmetric. Asymmetry of the Intertropical Convergence Zone There are a number of explanations of the asymmetry of the Intertropical Convergence Zone (ITCZ), known by sailors as The Doldrums.
Tropical Storm Agatha Tropical Storm Agatha Tropical Storm Agatha was a weak but catastrophic tropical cyclone that brought widespread floods to much of Central America, and was the deadliest tropical cyclone in the eastern Pacific since Hurricane Pauline in 1997. The first storm of the 2010 Pacific hurricane season, Agatha originated from the Intertropical Convergence Zone, a region of thunderstorms across the tropics. It developed into a tropical depression on May 29 and tropical storm later, it was dissipated on May 30, reaching top winds of 45 mph ( and a lowest pressure of 1000 mbar (hPa; 29.53 inHg). It made landfall near
