The two main categories of cyclones are tropical (forming in the tropics) and extra-tropical (forming outside of the tropics). discuss the stage of development of the tropical cyclone nivar These phenomena have different names depending on their intensity, measured by the strength of the surface wind. In the peripheral zone, hundreds of kilometres beyond the core, the horizontal flow is less symmetrical and the radial component of the wind is proportionally larger. No large changes in wind speed and direction with height (known in meteorological terms as low wind shear). This is about 50% more destructive than the winds of Hurricane Juan (2003).

This includes information on how they are named and categorised, maps of the tracks of all cyclones since 1992, notes on how the storms are forecast and links to information on how climate change may affect the formation of these systems in the future. The red arrows indicate where cool air is sinking. Hurricane Gonzalo Eyewall Replacement Cycle (October 14-17, 2014). Tropical cyclones only form over oceans, never over land, as they need sources of both heat and moisture. Strong winds causing a shear at altitude (25000 to 60000+ feet) interrupts that flow minimizing development. The JTWC designated it as a category 1 tropical cyclone of 130 kmph. The scale proposed in 1977 by the Americans H.S. Geography, 22.06.2019 15:00.
