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.
The main tool meteorologists use is Doppler radar, which can detect a tornado or the rotation in a storm that can produce them. There are also spotters, who report sightin â¦ gs of tornadoes and other weather hazards.
