Jet streams are fast-flowing air currents in the atmosphere, crucial for weather patterns. Major jet streams, like the polar front and subtropical jets, exist at high altitudes and influence global weather. They form due to temperature contrasts between cold polar and warm tropical air, creating pressure gradients. The Coriolis force affects their direction, causing them to flow west to east. Seasonal changes impact their strength and position, affecting weather systems. Jet streams can steer low-pressure systems, causing wet or dry conditions. Their meandering can lead to weather system development or stagnation.
