PPT-Formation of the Extratropical Cyclone (Cyclogenesis)

geogwwwsbsohiostateeducoursesG620ASP620Lecture10ppt Cyclogenesis Extratropical cyclones often form when an upper level trough eg a shortwave approaches a front that is stationary or moving relatively slowly. Satellite cl oud imageries are used along with other meteorological features to estimate t he intensities and the wind speed associated with these intense systems The satellite cl oud configurations expressed by T numbers have unique relati onship w : Then (1979) and Now (2014).
