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.
1 A research meteorologist studies more specific areas of weather like severe weather or climate change. They can also develop tools like radar or weather models to help other meteorologists in their jobs.  A meteorologist in the military makes weather observations and forecasts for missions around the world.
