What is a prevailing wind apes?

What is a prevailing wind apes?

prevailing winds. differing directions of air movement, major surface winds that blow almost continually and help to distribute heat + moisture over earths surface, drive ocean currents. ocean currents.

How are winds affected by global climate change apes?

Connects most of life on earth; global circulation of air and water that uses different amounts of rain fall at different latitude. As the Earth spins on the axis, the equator spins faster than the poles; north to south air currents are deflected, which curves the global wind patterns (called the prevailing winds).

What is the Coriolis effect apes?

Coriolis effect. The apparent curving of the path of an moving object moving through the air from an otherwise straight path due to the earth’s rotation; objects are deflected clockwise in the Northern hemisphere and counter-clockwise in the Southern hemisphere.

What are La Nina apes?

La Niña. When a La Niña occurs, it is a cooling of the Pacific Ocean between Papua New Guinea and South America. This is the opposite of an el niño. The formation of a la niña begins when the trade winds strengthen causing warm surface water to be pushed further away from the west coast of South America.

What is Enso apes?

El Nino-Southern Oscillation (ENSO) a periodic ocean anomoly caused by upper atmosphere changes in the Southern Hemisphere that weaken or reverse the trade winds and cause warm water to move eastward across the Pacific basin.

How does wind control ocean currents apes?

As prevailing winds blow over the ocean surface, it produces currents. These ocean currents redistribute heat from the warmer waters at the equator into colder regions. Water also mixes vertically as denser colder water sinks and warmer water rises.

What does a La Niña winter mean?

Meaning “little girl” in Spanish La Niña simply refers to “a cold event”. During a La Niña year, winter temperatures are warmer than average in the south and cooler than normal in the north.

What is loam apes?

LOAM. a soil with roughly equal proportions of sand(40), silt(40), and clay(20), the ideal soil.

What is permeability and porosity?

Porosity: is a measure of the void spaces in a material. Permeability: a measure of the ability of a material (such as rocks) to transmit fluids. Porosity and permeability are related properties of any rock or loose sediment. Both are related to the number, size, and connections of openings in the rock.

What do you mean by prevailing winds?

A wind that blows predominantly from a single general direction. The trade winds of the tropics, which blow from the east throughout the year, are prevailing winds. See illustration at wind. QUIZ YOURSELF ON AFFECT VS.

Why do winds rise above the equator?

PREVAILING WINDS. Air from the upper levels of the atmosphere flows in on top of it increasing the weight and creating an area of high pressure at the poles. The air that rises at the equator does not flow directly to the poles. Due to the rotation of the earth, there is a build up of air at about 30° north latitude.

Why do the wind speed and direction vary?

Even allowing for the effects of surface friction, the winds, locally, do not always show the speed and direction that would be expected from the isobars on the surface weather map. These variations are usually due to geographical features such as hills, mountains and large bodies of water.

What direction do winds blow in the upper levels?

Winds in the upper levels will blow clockwise around areas of high pressure and counterclockwise around areas of low pressure. The speed of the wind is determined by the pressure gradient. The winds are strongest in regions where the isobars are close together.
