Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere (a low-pressure area). [1] Cyclogenesis is an umbrella term for at least three different processes, all of which result in the development of some sort of cyclone , and at any size from the microscale to the synoptic scale .
A low-pressure area is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. [1] The formation process of a low-pressure area is known as cyclogenesis. [2]
The northwestern Mediterranean and the Gulf of Genoa in particular, are not only a transition area for passing cyclones, but are frequently areas of cyclogenesis. [3] [4] Low pressure areas move into or are formed as a result of North Atlantic air entering the Mediterranean Sea between the Alps and the Massif Central, via the Rhone Valley, or ...
Diagram of a cyclone in the early stages of occlusion in the Northern Hemisphere. In meteorology, an occluded front is a type of weather front formed during cyclogenesis.The classical and usual view of an occluded front is that it starts when a cold front overtakes a warm front near a cyclone, such that the warm air is separated (occluded) from the cyclone center at the surface.
The formation process of a low-pressure area is known as cyclogenesis. In meteorology , atmospheric divergence aloft occurs in two kinds of places: The first is in the area on the east side of upper troughs , which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere).
Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least 26.5 °C (79.7 °F)), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear.

Tropical cyclogenesis is the development and strengthening of a tropical cyclone. [28] The mechanisms by which tropical cyclogenesis occurs are distinctly different from those that produce mid-latitude cyclones. Tropical cyclogenesis, the development of a warm-core cyclone, begins with significant convection in a favorable atmospheric ...
There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low pressure center, a pre-existing low level focus or disturbance, and low vertical wind shear.
