How does typhoon start

This article was published more than 8 years ago. Some information may no longer be current. Typhoons start off as tropical thunderstorms. The strong winds pull in moisture from the oceans. The thunderstorms convert the moisture into heat. The heat causes more air to flow to the centre of the storm causing evaporation.

All the heat and air flow toward the eye creating the typhoon. This is a space where subscribers can engage with each other and Globe staff. It works like this: if a body moves along the surface of the earth, it is deflected to the right all the time in the Northern Hemisphere, and to the left - in the Southern Hemisphere. Let's get back to the tropical cyclone. Thanks to the Coriolis force, the air going to this funnel starts to rotate.

Therefore, the top of a tropical cyclone looks like a funnel. A tropical cyclone loses its strength when it is no longer in contact with the warm and humid surface of the ocean.

For example, if it passes over a cold current, or goes to land, it will weaken and begin to collapse. Cold fronts and warm fronts explanation in simple words.

How breeze works simple explanation. People call these storms by other names, such as typhoons or cyclones, depending on where they occur. The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic Ocean or eastern Pacific Ocean are called "hurricanes. 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. The warm, moist air over the ocean rises upward from near the surface.

Because this air moves up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises, causing an area of lower air pressure below. A cumulonimbus cloud. A tropical cyclone has so many of these, they form huge, circular bands.

Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that "new" air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds.
