It controls where the clouds go. It also causes high and low pressure systems
The jet streams generally have a moderating effect on US weather. The rapidly moving cold air helps to create weather fronts by altering pressure and precipitation relationships. Even though the jet streams reside above 10,000 ft , they impact surface conditions through complicated relationships of changes in barometric pressure, temperature, and relative humidity.
Because they contribute to worldwide weather patterns.
Weather System: The Weather System is made out of jet streams, fronts, temperatures, precipitation, and air.
It makes the air move faster or quicker
you mean jet streams...or thermals?
Jet streams give off chemicals that penetrate the air and trickle down to where we breathe. Streams also affect the weather because of the jets high speed, potentially causing storms and tornadoes if two jet streams intersect.
Jet streams are fast-moving air currents in the atmosphere, usually found at high altitudes. They are caused by temperature differences between cold polar air and warm tropical air. Jet streams affect climate by influencing the movement and intensity of weather systems. They can bring storms and precipitation to certain regions while creating dry and stable conditions in others. Changes in the jet stream pattern can lead to shifts in weather patterns and can impact long-term climate variability.
Because jet streams are above the friction layer, they have a negligible effect. The wind is balanced by the Coriolis effect and the pressure gradient so that the winds flow parallel to isobars.

The various jet streams steer the weather (they push the fronts), as they move they can cause large changes in local weather (block rain or cause rain ... make it cold or hot).
