Intertropical Convergence Zone

           The Intertropical Convergence Zone (ITCZ), known by sailors as The Doldrums, is the area encircling the earth near the equator where winds originating in the northern and southern hemispheres come together.The ITCZ appears as a band of clouds, usually thunderstorms, that circle the globe near the equator. In the Northern Hemisphere, the trade winds move in a southwestern direction from the northeast, while in the Southern Hemisphere, they move northwestward from the southeast. When the ITCZ is positioned north or south of the equator, these directions change according to the Coriolis effect imparted by the rotation of the earth.
            We are now experiencing the change in our climate. Therefore, it may have a fair tomorrow nor a good one. ITCZ brings rain in the Earth because it brought the cloudiness, thunderstorms nor precipitates rain.On or near the equator, where average solar radiation is greatest, air is warmed at the surface and rises. This creates a band of low air pressure, centered on the equator. This rising air comprises one segment of a circulation pattern called the Hadley Cell. The rising air is replaced by the Trade winds approaching the equator from north and south. As the trade winds meet near the equator, surface convergence and uplift take place.
