Intertropical Convergence Zone (ITCZ)

Intertropical Convergence Zone

(also known as ITCZ)

• Known by sailors as doldrums. The area encircling the Earth near the equator where winds originating in the northern and southern hemisphere come together.
• Originally identified from the 1920's to 1940's as the "intertropical front" (ITF), but after the recognition in 1940's and of 1950's of significance wind fiels convergence in tropical convergence in tropical weather production, the term "ITCZ" was then applied.
• It appears as a band of clouds usually thunderstorms that circle the globe near the equator.
• Location varies over time.

South Pacific Convergence Zone

(also known as SPCZ)

• A reverse-oriented, or west-northwest to east-southeast aligned, through extending from West Pacific warm pool southwards towards French polynesia.

Effects on weather:

       * It drastically affects the rainfall in many equitorial nations,      

          resulting in the wet and dry seasons of higher latitudes.

• Tropical cyclones depends upon low-level vorticity as one of its six requirements, and the ITCZ fills this role as its zone of wind change and speed, otherwise, known as horizontal wind shear.

1. Today I learned that Intertropical Convergence Zone (also known as ITCZ) is the one who plays as the zone of wind change and speed, otherwise known as horizontal wind shear.
2. I will apply my learnings about ITCZ in my everyday life. Perhaps when I watch the television and a weather update can be seen. I will explain it to myself so that my understanding about this matter becomes deep. I will also tell my family about it so that they would be able to know about this or relieve they're forgotten knowledge about the subject at hand.
3. Learning about this phenomenon is important because not everyday are we safe about the disasters coming from mother nature or the so-called known natural calamities. We should atleast understand about this to be able to be ready about it.
4. On a larger scale, I will share my learnings about this phenomenon to others because I want them to know about this too and think the same way that I do. For example, they think that a tropical depression is not a thing to be worried about, such is the thought of people from higher standings or those who live in places where typhoon is not destructive. But what about those people who live in places where typhoon is one of the scariest thing in the world. Those people are scared to the bone about this phenomenon because it will most likely kill them or make them suffer in their life. I want people to start thinking fairly about things in the world. One of it is the ITCZ. They should know the destructive part of this phenomena in our daily lives. So they should be prepared and refrain from contributing to the development of this phenomena into the negative part.
5. I need to know more about this ITCZ and what difference will it make if it's not around. (weird huh?)

Well that's all. Thank you for reading.
