What is cold dry dense horizontal air currents?
Cold dry dense horizontal air currents refer to the movement of air that is sinking toward the Earth's surface. These currents are often associated with high pressure systems and can bring clear skies and stable weather conditions. They are common in regions where cold air masses are present, such as polar regions.
What is the direct cause of surface currents?
The correct answer is differences in temperature *and* differences in salinity between the tropic and polar regions. However in the tropic regions the currents are started by the prevailing winds. And in the polar region the more saline and therefore, denser waters in the current sink to the bottom, which of course is caused by gravity.
What is the difference between tropical and polar air mass?
Tropical air masses are warm and moist, originating from the equator, while polar air masses are cold and dry, originating from the polar regions. Tropical air masses bring warm temperatures and humidity, while polar air masses bring cold temperatures and dry conditions. When these air masses meet, they can create weather changes and precipitation events.
How cold can the polar regions get?
Temperatures in the polar regions can drop as low as -90°C (-130°F) during the winter months. These extreme cold temperatures are due to the lack of sunlight, thick ice cover, and freezing winds that are characteristic of polar climates.
Air currents that blow near the north and south poles are the?
Polar easterlies. They are cold, dry winds that blow from the polar high-pressure areas towards lower latitudes.
What are the possible temperatures of a surface current?
Surface currents can have temperatures ranging from freezing temperatures in polar regions to warm temperatures in tropical regions. The specific temperature of a surface current is influenced by factors such as the location of the current, the season, and the interaction with other currents or land masses.
Difference between cold and warm currents?
Warm currents are warm whereas cold currents are cold. Warm currents flow from the equatorial regions towards the polar regions whereas cold currents flow from the polar regions to the equatorial regions. By- Avyukt Sharma

What factors set surface ocean currents into motions?
Factors that set surface ocean currents into motions are the global circulation cells (Hadley, Ferrel, Polar), the Coriolis effect, and the continental deflection.

Surface currents are driven by what?
by the currents under it, if you have watches Finding Nemo (ARR) they go in the EAC East Atlantic Current, on the surface of this current, there is a similar current, although it is not as fast or as strong as Underwater in the eac.
What regions of the globe do warm surface currents originate?
The equator.From there they flow to the North or South Poles in order to cool them.
What direction do cold currents flow in the northern hemisphere?
warm surface currents come from the polar and temperate latitudes, and they tend to flow towards the equator. Like the warm surface currents, mainly atmospheric forces drive them. Gyres form when the major ocean currents connect. Water flows in a circular pattern-clockwise in the northern hemisphere, and clockwise in the Southern hemisphere.
Do cold surface currents generally originate near the North or South pole?
Both polar seas -- the Arctic in the north and the Southern Ocean in the south -- generate cold surface sea water.
What is the difference between maritime tropical and polar?
Compared to a maritime tropical airmass, a maritime polar airmass has lower temperature and less water vapor.
What type of current creates cooler climates in coastal areas?
Ocean currents that originate from high latitudes and flow towards the equator create cooler climates in coastal areas. These currents bring cold water from polar regions, which in turn cools the surrounding air and moderates temperatures along the coast. An example of this is the California Current along the west coast of the United States.
Where would the temperature of the ocean probably be lowest?
The temperature of the ocean is usually lowest at the poles, especially in the Arctic and Antarctic regions, where cold polar currents circulate and ice cover can form. These areas receive less direct sunlight and experience colder air temperatures, resulting in colder ocean temperatures.
