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.
Changes in observing techniques pose a major challenge when studying past hurricanes. Tropical cyclones have been routinely monitored by aircraft for 60 years or less, and by satellite for only 20 to 40 years, depending on the ocean.
