Hurricanes do not form over equatorial waters because the Coriolis force is too weak near the equator. Recall from Lesson 11 that the Coriolis force is a force caused by the rotation of the earth that influences the direction of wind flow. Do hurricanes occur near the equator? Hurricanes are the most violent storms on Earth.
Why do Hurricanes never cross the equator?
The reason hurricanes don’t cross the equator is that storms have a tendency to drift towards poles and it’s rare for the atmosphere to create a situation to pull a storm toward the equator. This is termed the Beta Effect, which is a consequence of the Coriolis effect.
So, why are tropical cyclones not formed near the equator?
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.
Do hurricane form close or far from the equator?
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.
Hunderstorm activity which allows the heat stored in the ocean waters to be liberated for the tropical cyclone development. Relatively moist layers near the mid-troposphere (5 km [3 mi]). A minimum distance of at least 500 km [300 mi] from the equator.
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.
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.
Why are there no seasons around the equator?
Republic of the Congo. The Democratic Republic of the Congo.
Why is there less seasonal change at the equator?
While the poles get more or less light because of the tilt of the earth, the middle stays centered, so people near the equator have about the same length of daylight all year and don’t have as many seasonal shifts in light and temperature. The amount of sunlight in any given location makes a big impact on how cold or hot it is.
