Boundary current It is because of western intensification that the currents on the western boundary of a basin (such as the Gulf Stream, a current on the western side of the Atlantic Ocean) are stronger than those on the eastern boundary (such as the California Current, on the eastern side of the Pacific Ocean).he main ocean currents involved with the North Pacific Gyre. Boundary currents are ocean currents with dynamics determined by the presence of a coastline, and fall into two distinct categories: western boundary currents and eastern boundary currents.

Ocean Currents Warm surface currents invariably flow from the tropics to the higher latitudes, driven mainly by atmospheric winds, as well as the earth's rotation. Western boundary currents are good examples of warm surface currents: they are warm and fast, and they move from tropical to temperate latitudes § .Cold surface currents come from polar and temperate latitudes, and they tend to flow towards the equator.he California current is an eastern boundary current. It's broad, slow, cool, and shallow. Eastern boundary currents are often associated with upwelling. The Somali current, off Africa's eastern coast, is unusual because it reverses direction twice a year.

Wind Driven Surface Currents: Western Boundary Currents Background Transport of surface waters toward the western boundary of the ocean basins causes the ocean-surface slope to be steeper on the western side (versus eastern side) of a gyre (in either hemisphere). A steeper ocean-surface slope translates into a faster geostrophic flow on that side of the gyre.

Why do ocean currents in the northern hemisphere move in a clockwise direction while currents in the southern hemisphere move in a counterclockwise direction? So in Northern hemisphere, the west-moving northern equatorial warm current gets deflected towards north due to Coriolis effect and bifurcation at the continents, and in similar way a full circle/ gyre gets completed. In a nutshell, two major factors are: wind direction and landmass (continents) diversion/ interruption.

Upwelling If the wind blows parallel to the coast in the northern hemisphere (such as the coast of California, where the wind blows South), then Ekman transport can produce a net movement of surface water 90° to the right. This may result in coastal upwelling. If the wind blows parallel to the coast in the northern hemisphere (such as the coast of California, where the wind blows South), then Ekman transport can produce a net movement of surface water 90° to the right.

- Gulf Stream. The Gulf Stream is one of the fastest moving warm currents. The current is strong and the waters have a high salinity. The Gulf Stream originates in the deep waters of the Gulf of Mexico, travels around the tip of Florida and moves at nearly 6 miles per hour to the North Atlantic.This warm current is approximately 62 miles wide and 3,000 feet deep on average.arm currents invariably originate in the earth's tropical regions, along and near the equator. Atmospheric winds, the earth's rotation, even the salinity of the water affect the movement of these warm currents. Usually they flow from warmer regions to cooler ones, helping balance the earth's temperatures.

Wind Driven Surface Currents: Upwelling and Downwelling Background Hence, westward-flowing, wind-driven surface currents near the equator turn northward on the north side of the equator and southward on the south side. Surface waters are moved away from the equator and replaced by upwelling waters. Equatorial upwelling.

- In contrast, cold water currents cool the air above them and since cold air has less of an ability to hold moisture than warm air, these currents tend to bring cool, dry weather to adjacent land areas. Fog is often found along the land-sea borders where cold ocean currents exist.n contrast, cold water currents cool the air above them and since cold air has less of an ability to hold moisture than warm air, these currents tend to bring cool, dry weather to adjacent land areas.

- The Gulf Stream is a powerful western boundary current in the North Atlantic Ocean that strongly influences the climate of the East Coast of the United States and many Western European countries.Click the image for a larger view.here are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).

Why is the west coast warmer in winter months and cooler in summer months than the east coast? Water cycles up the east coast from the equatorial region (Caribbean Sea) in what's know as the Gulf Stream, so it's relatively warm. Water on the west coast cycles down from … the arctic (Bering Sea and Gulf of Alaska), so its relatively cold.

- Since cooler air is denser and heavier than warm air, high pressure tends to form over the water and low pressure over the land. Air begins to flow inland cooling the temperature. At night, the land cools more than the water and the reverse pressure and offshore wind flow tends to occur (called a land breeze).

Climate Change & The Jet Stream But just as certainty builds for a poleward shifting jet, there still remain questions about whether the jet is amplifying and promoting more blocking patterns. The work of Dr. Jennifer Francis and Steven Vavrus shows that as the Arctic warms faster than the tropics, a lessening of the temperature gradient between the equator and the North Pole slows the jet stream.

- Figure 8.14 Jet stream winds and surface systems. Recall that surface air converges and rises in low pressure systems. To maintain low pressure at the surface the rising air must diverge at the top. It is this upper air divergence in the jet stream that pulls air upward to help form surface cyclones.In so doing, surface cyclones tend to follow the path of the jet stream.Figure 8.14 shows the relationship between upper-level flow and surface pressure systems.eather Systems Surface Cyclones and the Jet Stream Above the polar front lies the polar front jet stream, a zone of faster moving air in the upper troposphere. The jet stream takes on a meandering pattern with regions of faster and slower air. Within the jet stream there are regions air convergence and divergence.

Hot water freezes faster than cold - and now we know why. Hot water seems to freeze faster than cold water, known as the Mpemba effect. The effect was named after the Tanzanian student who in 1963 noticed that hot ice cream mix freezes faster than a cold one.

Melting Arctic Sea Ice and Ocean Circulation Melting Arctic Sea Ice and Ocean Circulation Seawater moves through the Atlantic as part of the thermohaline circulation (also called the Global Ocean Conveyor), the regular pattern by which seawater travels the world’s oceans. The water in the Global Ocean Conveyor circulates because of differences in water density, which are caused by differences in temperature and salinity. Colder water is denser than warmer water, while saltier water is denser than less salty water or fresh water. Water heated near the Equator travels at the surface of the ocean north into cold high latitudes where it becomes cooler. As it cools, it becomes denser and sinks to the deep ocean.

- Normal sea surface temperatures in Pacific tend to be warmer in the west because of upwelling, where warm water flows west because of trade wind … s and colder water rises up to replace the warm water in the Eastern Pacific. During El Nino, the trade winds get all screwed up and warm water is spread out more evenly in the Pacific.

Can Hot Water Freeze Faster Than Cold Water? 1 Supercooling-Hot water tends to experience less of a supercooling effect than cold water. 2  This makes it more likely to become solid when it reaches the freezing point of water.3  Convection-Water develops convection currents as it cools. This makes it more likely to become solid when it reaches the freezing point of water. 2  Convection-Water develops convection currents as it cools. 3  Water density usually decreases as temperature increases, so a container of cooling water typically is warmer on top than on the bottom.

Which currents carry warm water away from the equator? Why do warm ocean currents cool as they flow along a coastline away from the equator? Warm ocean currents cool as they flow along a coastline away from  the equator because sand and minerals are transported by ocean  currents away from the equator. Making the world better, one answer at a time.

Currents in the Earth's System Large convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading centers, creating divergent plate boundaries. As the plates move away from the spreading centers, they cool, and the higher density basalt rocks that make up ocean crust get consumed at the ocean trenches/subduction zones.

Is schizophrenia genetic? As with many mental health disorders, the causes of schizophrenia are complex and not yet fully understood. What we do know indicates that an interaction between genetic and environmental factors is what determines whether someone will develop schizophrenia. There is no question that genes play a role in schizophrenia. People with a close relative who is schizophrenic (such as a parent or sibling) are at an increased risk of developing the disease themselves--a 10% risk compared to the 1% found in the general population.

Wind Driven Surface Currents: Western Boundary Currents Background Flows in the major western boundary currents are 50 to 100 times the total water discharged by all the world's rivers. As shown here for the North Atlantic but also true for all ocean basins, the ocean surface slope is steeper on the western side of an ocean basin than on the eastern side. Consequently, surface ocean currents are stronger, narrower, and deeper in all western boundary regions.

05.02 Ocean Currents Strong winds moving across an expanse of water move the surface of the water. These strong winds are not random breezes; the major winds that most often effect the creation of ocean currents are the Westerlies, which blow west to east, and the Trade Winds, which blow east to west. 2.
