How Do Jet Streams Affect the Weather?


Jet streams are narrow fast flowing 'rivers' of air. They are formed by temperature differences in the upper atmosphere, between the cold polar air and the warm tropical air. They play a key role in the weather by steering storms and also helping determine where storms form.

The jet stream is a 'river of air' high up in the atmosphere (above 20, 000 feet). These affect weather by steering storms. They blow from the west to the east in the northern hemisphere and do migrate from a northerly to a southerly route. If the jet stream is in a southerly path, the weather to the north of it will generally be cooler. You can find more information here: http://www. usatoday. com/weather/wjet. htm
