A jet stream occurs when warmer air lies above polar air.
The Polar Jet Stream, or more generally the Polar Front.
The jet stream
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
a jet stream is important because of climate control

Because a jet stream goes past England every year which carries a lot of wind, rain, clouds etc... but sometimes it only goes past some parts of England which means that the jet stream going past them will be more warmer where as the places that the jet stream is going past them, is going to be cold.
Put simply, the jet stream mixes the cold polar air with warm air from the tropics and vice versa, meaning climates across the UK are more temperate. This can have a number of effects, depending on the position of the jet stream in relation to the UK, and the direction and angle of travel of the jet stream. For example, if it is south of the UK, this will cause colder weather. If, on the other hand, it is north of the UK, the he opposite will happen - warmer weather will ensue. When the jet stream is positioned directly over the UK, the weather will be wetter and windier than usual.

The polar jet-stream forms at the boundary of cold, dry polar air to the north and warmer, more moist air to the south.
