Jet Stream a fairly narrow zone of very strong
winds in the upper troposphere.

• Winds
• Most common in middle latitudes
• Usually from the west

• Air masses have different temperature and
  humidity characteristics.
• Where two different air masses meet a jet stream
  forms.
• When people refer to the jet stream they mean
  the polar jet stream. This is the strongest jet
  stream.

4

• Low pressure cells bring inclement weather. The
  jet stream moves them or blocks them, affecting
  the weather in different locations.

The Gulf Stream is a powerful, warm surface ocean
current in the North Atlantic Ocean.

• One of the strongest known currents

6
As the Gulf Stream reaches Cape Hatteras, NC the
cold current that flows from the north separates
the Gulf Stream from the coast.

When the Gulf Stream waters from the south
(Florida) combine with the cold winds, a dense
concentration of fog forms with an immense heat
transfer causing atmospheric storms to intensify.

The Gulf Stream carries warm water from near the
Equator up the eastern coast of North
America.The warmer ocean temperatures moderate
the air temperature over land.Air travelling
over the warm Gulf Stream water picks up moisture.
