Weather Tidbits: Tropical Decay

This Weather Tidbits deals with how a tropical cyclone forms but also dissipates. Tropical cyclones form from unstable air with temperatures that cool with height; which leads to convection or vertical motion and clouds for thunderstorms to form in the center.  Ocean temperatures are over 80° to supply energy to sustain the storm are a key ingredients for tropical cyclone. A hurricane which is more wind- or surge-based; dissipates on land when it makes landfall and is cutoff from the energy source of the warm ocean water. The transition from hurricane to tropical storm and tropical depression make the cyclone more rain-based; where lastly it becomes a remnant low or extra-tropical cyclone.
