what is the difference between air current and wind?

Air that moves horizontally along the earth's surface is called wind. The temperature and humidity varies in the wind system. Air current: The vertical or nearly vertical movement of air is referred to as air current.

Upwind is the direction the wind is coming from. If the wind is blowing from the Northwest (blowing toward the Southeast) then the upwind direction is toward the Northwest and the downwind direction is toward the Southeast.

There is a difference. Electricity is a general term used to call electric energy. But electric current is a physical quantity of electrical energy which defines amount of electrons. ... Electric current refers to the movement or flow of charge.

Wind is air in motion. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind: speed and direction.

In an AC generator, the coil through which current flows is fixed and the magnet usually moves. The south and north poles of the magnet make the current flow in opposite directions, thereby creating an alternating current. In contrast, the coil in a DC generator is not fixed; rather it rotates in a fixed field.

In an AC generator, the electrical current reverses direction periodically. In a DC generator, the electrical current flows only in one direction. In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less.

Explain how the Coriolis effect, friction, and pressure gradients affect wind direction. Wind is the product of pressure gradients established between high and low pressure systems. These systems are constantly moving and changing.

Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

Wind pressure is the force of the wind nlowing against something. Air pressure is the wieght of the atmosphere. ... Between an area of high pressure and low pressure, wind is the movement of air in order to (attempt to) equalise the pressure. The greater the difference in pressure, the faster the air will move.

Wind has two important characteristics—direction and speed. The direction of wind can be gauged using an instrument called the wind vane. It is also called a weather vane. Every wind vane has two parts, the front and the rear.

An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. In an AC generator, the coil through which current flows is fixed and the magnet usually moves. ... The two backup generators are used for different purposes.

Wind direction is measured relative to true north (not magnetic north) and is reported from where the wind is blowing. An easterly wind blows from the east or 90 degrees, a southerly from the south or 180 degrees and a westerly from the west or 270 degrees.

Originally Answered: What is the difference between electricity and electric current? Electricity is the word for electrical power provision, whereas electrical current designates the flowing of electrons or the displacement current that is a factor in the transport of electricity.

The greater the difference in pressure, the faster the winds. When a high- and a low-pressure air mass are far apart, air moves slowly from high to low pressure. When a high- and a low-pressure air mass are close together, air moves slowly from high to low pressure.

Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. ... Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions.

Water current is the continuous direct movement of water generated by forces acting upon these flows, (wind, breaking waves, temperature, Coriolis effect, etc.) ... Air currents are caused by differences in temperature, pressure, or impurity concentration.

Wind results from a horizontal difference in air pressure and since the sun heats different parts of the Earth differently, causing pressure differences, the Sun is the driving force for most winds.
