WebJet streams are formed where cold air from the poles meets warm air from the tropics. The temperature difference creates a pressure gradient, which in turn creates high-speed winds. These winds move in a wavy pattern known as Rossby waves, which can be amplified or weakened by various factors, such as the location of high and low-pressure systems.
