The tempurate differences creates the jet stream. Wind is caused by the uneven heating of earth's surface and the differences of air pressure. Cold polar air creates low air pressure and a cold surface which creates wind.

What determines how far south the the cold air from the north pole travels?
The jet stream
Which is stronger polar jet stream or subtropical jet stream?
Polar jet stream is stronger.
What accompanies a cold spell in Minnesota?
Minnesota receives arctic air when the polar jet stream moves south across Canada.
Why does jet stream move faster in the winter?
The polar jet-stream forms at the boundary of cold, dry polar air to the north and warmer, more moist air to the south.
What jetstream brings in cold dry air?
Polar Jet Stream.
The fast dense current of air which flows across the northern hemispher dividing cold arctic air from warmer southern air is called what?
The Polar Jet Stream, or more generally the Polar Front.
What occurs when warmer air lies above polar air?
A jet stream occurs when warmer air lies above polar air.
Which statement is true of jet streams?
The polar jet stream is generally stronger than the subtropical jet stream
Lies along the polar jet stream?
The su polar low lies along the polar jet stream :)
What is the difference between a continental jet stream and a polar jet stream?
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
What usually accompanies a cold spell in Minnesota?
Minnesota receives arctic air when the polar jet stream moves south across Canada.
How does the polar front influence the development of the polar-front jet stream?
The northernmost (and/or southernmost) of the various jet streams that circle the Earth.
