Formation of a cyclone
Bildnummer 13495692
| When the Sun warms the top layer of the ocean, strong updrafts of warm, humid air are formed by convection, creating a low-pressure zone. This provokes the convergence of low-altitude winds, also loaded with humidity, which feed the rising movement. Once in contact with cooler air, the water vapour condenses and forms a storm cloud. The latent heat released by the condensation accelerates the rising of the air within a column that sucks up more mid-level warm, humid air. At the top of the cloud, diverging winds form and the air is expelled. As it descends, the air is heated and sucked in by the surface low-pressure zone. The cyclonic process has started. | |
