Cyclones

A cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate in a counter-clockwise direction in the Northern Hemisphere and in a clockwise direction in the Southern Hemisphere.

Formation of Cyclones

Cyclones typically form over warm ocean waters, where the air is warm and moist. As the warm air rises, it creates an area of low pressure at the surface. This causes surrounding air to rush in to fill the void, creating a rotating system of winds. The Earth's rotation, known as the Coriolis effect, then causes the winds to spiral and form a cyclonic pattern.

Types of Cyclones

There are different types of cyclones, including tropical cyclones, extratropical cyclones, and tornadoes. Tropical cyclones, also known as hurricanes or typhoons, are intense storm systems that form over warm tropical oceans. Extratropical cyclones, on the other hand, form in the mid-latitudes and are associated with fronts and weather systems. Tornadoes are small, but intense cyclones that form within severe thunderstorms.

Effects of Cyclones

Cyclones can have a range of effects, including strong winds, heavy rainfall, storm surges, and flooding. These extreme weather conditions can cause widespread damage to infrastructure, homes, and agricultural crops. In addition, cyclones can also lead to loss of life and displacement of people.
