Why jet streams have such a high velocity?
Why jet streams have such a high velocity? Temperature also influences the velocity of the jet stream. The greater the difference in air temperature, the faster the jet stream, which can reach speeds of up to 250 mph (402 kph) or greater, but average about 110 mph (177 kph). Can the jet stream reverse? Now, […]
