Intertropical Convergence Zone(ITCZ)


I learned that 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 hemisphere come together. It appears as a band of clouds, usually thunderstorms that circle the globe near the equator. It 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 location of the ITCZ varies over time. Over land, it moves back and forth across the equator following the sun’s zenith point. Over the oceans, the seasonal cycle is more subtle, as the convection is constrained by the distribution of ocean temperatures. Because of variation in the location of ITCZ, it drastically affects rainfall in many equatorial nations resulting in wet and dry seasons of the tropics instead of cold and warm seasons of higher latitudes. I want to know more about how ITCZ really affects the season of every place and the factors that cause it to occur. I would like to research on how we can anticipate its eventuality and consequently lessen the bad effects of ITCZ because according to the information I have read, ITCZ can cause severe droughts and flooding. I appreciate the fact that people are now being aware on the effects that ITCZ may brought to us, using technology and media we  can easily detect the weather system and share the information that we have gathered to us. I can apply my learning and insights in my daily living like for example finding ways to prevent/ lessen the damage that can be brought by ITCZ, we can plant trees to prevent severe floods and we can plan our crops to be planted that will fit the weather and can survive severe droughts and floods.
