Modern meteorologists use the numerical weather prediction method.  This method uses mathematical smulations of the earth to predict  the weather. A number of simulations ar â¦ e run in different countries  worldwide, using weather observations relayed from weather  satellites and radar as inputs to the simulations.
For hurricanes prior to Katrina, only limited tidal gage data and HMWs are available.
