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.
Meteorologists are able to predict the changes in weather patterns by using several different tools. They use these tools to measure atmospheric conditions that occurred in the past and present, and they apply this information to create educated guesses about the future weather.
