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 used for track tornadoes is doppler radar, which can measure wind speeds remotely. It can detect the signature of a tornado or the circulation from which one may â¦ form. However, doppler radar cannot determine whether or not a tornado is actually on the ground. For that trained weather spotters go out and report any tornado sightings.
