Are there typhoons in the Southern Hemisphere?

The southern hemisphere meets the conditions for typhoons to occur. Theoretically, there are also typhoons in the southern hemisphere.

Typhoons are powerful and deep tropical cyclones that form on tropical oceans.

The formation of typhoon The conditions necessary for the formation of typhoon: ①Extensive high-temperature ocean surface. The formation and development of typhoons requires huge energy, and its energy mainly comes from the latent heat released by the condensation of large amounts of water vapor. On the tropical ocean surface, the sea temperature is high and evaporation is strong. A large amount of heat and water vapor are transported to the atmosphere through turbulent motion. It has unstable conditions of high temperature and humidity. Its large amount of internal energy is a huge source of energy for the generation and development of typhoons. ②Suitable flow field. Suitable circulation conditions can initiate and induce disturbances in high-temperature and high-humidity air, causing the airflow to converge and rise. ③Appropriate geostrophic deflection force. After the airflow moves, there must be a certain deflection force. If the geostrophic deflection force does not reach a certain value, the airflow converging toward the center will reach the low-pressure center directly, causing it to be filled and unable to form a cyclonic vortex, and a typhoon cannot form. Therefore, typhoons mostly occur between 5° and 20° north and south latitudes. ④The vertical shear of the wind should be small. Under the action of geostrophic deflection force, convergent updrafts develop into cyclonic vortices. The air flow rises, adiabatic cooling produces condensation, and the latent heat released by the condensation warms the air. The vertical shear of the wind is small, which prevents latent heat from spreading outward and maintains the warm-core structure of the typhoon. The feedback effect of the warm heart causes the air pressure at the center of the typhoon to continue to drop, and the air vortex becomes stronger and stronger, and finally develops into a typhoon.

There are typhoons in both the northern and southern hemispheres, but due to the geostrophic deflection force, the direction of typhoon rotation in the southern hemisphere is opposite to that in the northern hemisphere.
