Hurricanes do not form at the equator because the Coriolis effect there is too weak there to initiate rotary motion of the storm. They do not form in the South Atlantic or eastern South Pacific because the waters there are too cool. Why do hurricanes not migrate far along the west coast before weakening quizlet?
Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator.
So, can there be Hurricanes at the equator?
If it is at equator, the latitude is zero degrees and hence sine of it is zero at the equator region. So, there is no possibility for the Hurricanes to be generated at the equator. When many thunderstorms rotate at a particular area with low pressure at the center region, it is called tropical depression.
The textbooks say that cyclones such as hurricanes (or typhoons as they’re called in the western Pacific) don’t form within 300 kilometers (about 186 miles) of the equator. Typhoon Vamei proved to be an exception to the rule.
Hurricanes do not form right on the equator because the Coriolis effect is minimal near the equator. If fact, they will not form within 200 miles of the equator for this reason. The Coriolis effect causes them to spin counterclockwisenorthern hemisphere and clockwise in the southern hemisphere.
Yet another inquiry we ran across in our research was “Why are tropical cyclones not formed near the equator?”.
This is what my research found. even if these conditions are in place, a tropical cyclone is not likely to form if it is not at least 300 or so miles from the equator. This is because of the lack of the Coriolis force. What is that? It is an apparent force caused by the rotation of the Earth.
A query we ran across in our research was “Why don’t hurricanes form?”.
Hence, Hurricanes also do not form . Coriolis force is considered as a force resulted from conservation of angular momentum. It solves the problem of spinning and every point on the globe changes the direction as well as acceleration.
Why there is no Coriolis force at the equator?
This is why there is no Coriolis force at the equator and why hurricanes rarely form near the equator. The Coriolis force is simply too weak to move the air around low pressure. Air prefers to flow from high to low pressure., Typhoon Vamei which formed near Singapore on December 27, 2001.
Why does it often rain near the equator?
The warm air can hold large amounts of water that evaporate from the equatorial oceans and land. As the warm air rises it cools, which reduces some of its ability to hold water. Areas near the equator receive large amounts of rain. Cool water over the equator cannot sink because hot air is rising below the cool air.
You should be asking “Why is it usually more humid near the equator?”
Heat is needed to evaporate water, changing it into vapor in the air. Because warm air can hold more moisture than cool air, locations with warm climates, such as those near the equator, generally have higher humidity than locations with cooler climates, such as those near the poles.
