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.
Data Collection Devices. Meteorologists use all kinds of equipment to measure the weather. These include thermometers, radar systems, barometers, rain gauges, wind vanes, anemometers, transmissometers, and hygrometers. Let's go through them one at a time and talk about what they do.
