21. This was partially due to decreased tropical cyclogenesis from African tropical waves, which are 1962. 22. The opposite of cyclogenesis is cyclolysis. 23. Thereafter, tropical cyclogenesis slowed in October, which featured only two systems, Gerda and Hattie. 24. Tropical cyclogenesis in the 1989 Atlantic hurricane season began with a tropical depression developing on June 16. 25. Tracking westward, the initial tropical depression intensified into a tropical storm several hours after tropical cyclogenesis . 26. Tropical cyclogenesis concluded with the formation of Kevin on 2 May, which dissipated on 12 May. 27. Next assume a surface baroclinic zone as mentioned above as this is a key ingredient to cyclogenesis . 28. A poleward heat flux is observed in unstable modes, yielding the positive feedback necessary for cyclogenesis . 29. An occluded front is formed during the process of cyclogenesis when a cold front overtakes a warm front. 30. Tropical cyclogenesis in the 1995 Atlantic hurricane season began with the development of Hurricane Allison on June 2.
