This tutorial has been all about hurricanes, how they form, grow and dissipate. In it we have learned that hurricanes form in the warm tropical atmosphere from prexisting thunderstorm complexes that have developed rotation at their mid to low levels. Using the energy stored up in the ocean in the form of latent heat the hurricane takes that energy to start up a positive feedback loop that slowly deepens the center and organizes the hurricane into a spiraling mass of thunderstorms. Once the hurricane moves over land it weakens rapidly as it is now seperated from the ocean and its latent heat source. The remnants of the storm may persist for days however dropping heavy rainfall far inland. We have also learned that a hurricane consists of a center of low pressure, called an eye that is surrounded by a ring of deep convection called the eye wall. It is here in the eyewall that the energy used to drive the storm is released by condensation of water vapor. Outside the eyewall, the moat exists and is a wide region of stratiform clouds. In the moat updrafts and downdrafts help moisten the storm's inflow.
The effects a hurricane will have on your city's weather depend on how far you will be from the storm. Far from the storm subsidence from the hurricane will lead to cloudless skies and hot dry weather. Near the storm, cloudiness, high wind and torrential rains will persist. As the storm moves inland it will bring the rain and clouds with it. Base your forecast off what these conditions typically bring.
