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.
Cave of the Winds (New York) and walkways. Tropical storm-like conditions can be experienced, as winds can reach up to 68 mph underneath the falls. The cave was obliterated in a massive 1954 rockfall and subsequent dynamiting of a dangerous overhang. Today, the "Cave of the Winds" is the name of a tourist attraction near the same site. An elevator takes people from the area between the American and Canadian Falls down to the level of the Niagara River at the base of the American Falls. A series of redwood decks and platforms allow sightseers to walk right up to the base of the Bridal Veil
