There are a number of structural characteristics common to all cyclones. A cyclone is a low-pressure area. A cyclone's center (often known in a mature tropical cyclone as the eye), is the area of lowest atmospheric pressure in the region.ropical cyclones form due to latent heat driven by significant thunderstorm activity, and are warm core. Cyclones can transition between extratropical, subtropical, and tropical phases under the right conditions.
A cyclone is formed over tropical seas. Winds from opposite directions meet. This air is heated by the warm seas and so evaporates moisture from the ocean. This warm air rises up rapidly, cools and condenses to form clouds and produces an area of very low pressure.When moisture and air mix, it makes a collection of thunderstorms from which a cyclone can develop.Water needs to be at least 26 degrees warm so a tropical cyclone can develop. More air is sucked in to take its place, and it too is heated and rises rapidly.his air is heated by the warm seas and so evaporates moisture from the ocean.
