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.
NASA Missions to Study Hurricanes. The ability to detect and track severe storms has been dramatically enhanced by the advent of weather satellites. Satellites have also helped scientists understand the mechanisms that drive hurricane formation and development. In its mission to study the Earth, NASA has developed and launched several innovative satellites that are providing unprecedented information on hurricanes. QuikSCAT
