from where do cyclones originate
Answers
Answer:
Explanation:
Most tropical cyclones form over the ocean at least 10 degrees north or south of the Equator. They never form along the Equator because a force, known as the Coriolis Force, has no effect there (or “is zero”, depending on who you ask). The Coriolis force is essential for tropical disturbances (waves that are not yet even a tropical depression) to develop and eventually rotate. They generally do not form outside the tropics, and will never be found in high-latitude regions. See the map below illustrating these points.
Generally, and simply, tropical cyclones can form when three ingredients are present: a warm ocean form which to draw water vapor containing latent heat, and atmospheric conditions that have a low wind shear, and in a region sufficiently far from the Equator to allow for the Coriolis Force to influence the system, as mentioned above.
In some areas, tropical cyclones originate from disturbances forced by land. For example, in the Atlantic, many tropical cyclones begin their life off the coast of Africa in an area known as the Main Development Region (often just referred to as the “M D R”) from African Easterly Waves.
Others, such as those over the ocean, form from the periodic breakdown of the Inter tropical Convergence Zone (or IT CZ). The IT CZ is basically a band of thunderstorms and heavy rain along the tropical regions around the globe. It changes location based on the season in the hemispheres, generally being located where it is warmest. IT CZ breakdown allows for disturbances to spin off of the IT CZ, and potentially form into tropical cyclones.
Of course, there’s a lot more to explore on this topic, as it is still a hot area of research in meteorology/atmospheric science.
These are all tropical cyclones, the terms “hurricane” and “typhoon” are just regional terms for tropical cyclones.
