What causes the jet streams to form?

Question

Quizplus · Accepted Answer

Jet streams form due to the presence of strong pressure and temperature gradients in the atmosphere. The differences in pressure and temperature between the polar and equatorial regions lead to the formation of these fast-flowing, narrow air currents high up in the atmosphere. The pressure gradient force acts to move air from high to low pressure, while the temperature gradient force acts to balance this pressure gradient by causing air to flow from colder to warmer regions. Together, these forces create the jet streams.
