                 What I did is I search what is the meaning of Inter tropical Convergence Zone (ITCZ) and what it is causes and effect especially to peoples live in earth. I learned how to be aware if there is ITCZ in our place and also to get ready when rains come in our place. I learned also what is ITCZ and what is the effect of it  in human life. It affect our weather and also the rainfall in our country. I can apply my learning's to my everyday life and to thought someone  to get ready and to apply it in there life.The Intertropical Convergence Zone (ITCZ), known by sailors as the doldrums, is the area encircling the earth near the equator where the northeast and southeastward winds 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.When the ITCZ is situated north of the equator, the southeast trade wind changes to a southwest wind as it crosses the equator. The ITCZ is formed by vertical motion largely appearing as convective activity of thunderstorms driven by solar heating, which effectively draw air in; these are the trade winds. The ITCZ is effectively a tracer of the ascending branch of the Hadley cell, and is wet. These is all i learned about ITCZ.
