GULF STREAM
A warm ocean current that flows from the Gulf of Mexico northward through the Atlantic Ocean
The Gulf Stream is a powerful current in the Atlantic Ocean. It starts in the Gulf of Mexico and flows
into the Atlantic at the tip of Florida, accelerating along the eastern coastlines of the United States
and Newfoundland. It is part of the North Atlantic Subtropical Gyre, one of the five major oceanic
gyres, which are large systems of circular currents and powerful winds.

The Gulf Stream is a western boundary current; its behavior is determined by the North American
coastline. Trade winds from Africa drive water in the Atlantic westward until it hits the coastline and
gets pushed northward. In turn, the Gulf Stream affects the climate of the areas closest to the current
by transferring tropical heat toward the northern latitudes. There is a consensus among scientists that
the climate of Western and Northern Europe is warmer than it would be otherwise because of the
North Atlantic Current, one of the branches of the Gulf Stream. [Video: Animation Reveals Ocean

southern hemispheres.
Shade the zones with color: Red or Orange - TROPICAL, Green - TEMPERATE, Blue POLAR
Label each on the zones with darker color or black directly on the map
To the left of the map in the margin, label the following:
TROPICAL:
23.5°S - 23.5°N
TEMPERATE (in both hemispheres):
23.5° - 66.5°
POLAR (in both hemispheres):
66.5° - 90°
To the right of the map in the margin, label the following:
TROPICAL:
Warm-hot and humid (rainy)
TEMPERATE (in both hemispheres):
usu. MILD; both hot & cold
POLAR (in both hemispheres):
cold and arctic
