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.
To measure wind speed and direction, a meteorologist uses an anemometer. One type of anemometer is a horizontal windmill; it has small plastic cups affixed to metal arms on a pivot that spins in response to the wind. A separate vane indicates the wind direction.
