Ocean Currents and Climate Study Guide

Ocean water The ocean water never stands still. Ocean currents are like rivers that move within the ocean. This movement influences the surrounding climate.

Surface Currents Surface currents are caused by the wind and usually move only the upper few hundred meters of water. Surface currents are caused by the wind and usually move only the upper few hundred meters of water. These currents do not move in straight lines. These currents do not move in straight lines.

Examples of Surface Currents Gulf Stream-originates near the equator and travels up the east coast-it is a warm current. California Currents-originates in the north and travels down the west coast-it is a cold current.

The Gulf Stream Current

The Jet Stream A jet stream is defined as a current of rapidly moving air that is usually several thousand miles long and wide, but is relatively thin. They are found in the upper levels of Earth's atmosphere at the tropopause

Jet Stream

Density Currents Occur when more dense seawater sinks beneath less dense seawater. Seawater becomes more denser when it gets colder or becomes saltier. This movement causes currents. Cold salty water is very dense so it sinks and slowly flows southward along the ocean floor.

Upwelling  A current in the ocean that brings deep, cold water to the ocean surface.  Surface winds blow parallel to the land because of the Coriolis effect.  Cold, deep water continually replaces the surface water that is pushed away from the coast.  This cold water causes cool summers and fog in San Francisco.

How the oceans influence climate The oceans influence climate over both long and short time periods. The oceans influence climate over both long and short time periods. The oceans and atmosphere are tightly linked and together form the most dynamic component of the climate system. The oceans and atmosphere are tightly linked and together form the most dynamic component of the climate system. The oceans play a critical role in storing heat. The oceans waters are constantly being moved about by powerful currents. These currents influence the climate by transporting heat.

How the oceans influence climate continued…  Currents involved in “deep-water formation” are particularly important for climate.  An apparently small change in just one aspect of the oceans behavior can produce major climate variations over large areas of earth.

Climate is not weather Climate- the average pattern of weather in a place. Weather- is the condition of the atmosphere at a particular place and time measured in terms of such things as wind, temperature, humidity, cloudiness, precipitation, and atmospheric pressure.
