The US was already geared for war, that's what the cold war was all about. However, US tactics and machines of war had to be modified somewhat for the Vietnam War.
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.
Typically working for government agencies or research organizations, meteorologists use radar information and computer models to predict atmospheric change. If the field of meteorology sounds interesting to you, read on to find out about education and career options.
