An isotach is a type of contour map that is used in meteorology to measure equal wind speeds. Through the use of contour lines and different colors, the different speeds and forces can be shown. This type of map is used to locate the jet stream and jet streaks. The picture above is an isotach for the United States. Using a key, the speed and force of the wind for different states can be determined by comparing the different colors and symbols.
