If the earth were not rotating, the wind would blow exclusively from high to low pressure. Close to the earth, it would be slowed by friction between the atmosphere and the earth's surface but would maintain the same direction with height. However, since the earth undergoes rotation, there is an apparent force acting on horizontal atmospheric motions when examined from a point of reference on the earth's surface. For example, [as] viewed from space(the absolute frame of reference), the [wind] flow [continues] in a straight line.

The jet stream is a fragmented global wind flow that encircles the mid-latitudes in a wavelike pattern. Embedded within this global wind belt are jet streaks. A jet streak is a segment of the jet stream that has relatively high velocity winds. ... Jet streaks are caused by a large low-level temperature gradient, thus they are more intense in the cool season when the differential in temperature between the polar regions and tropical regions is largest.

Actuator disk theory. The simplest model of a horizontal axis wind turbine(HAWT) is one in which the turbine rotor is replaced by an actuator disk which removes energy from the wind. As the wind strikes the actuator disk on the upwind side, the pressure rises there, and the wind is deflected away from the disk, causing a large wake downstream of the disk. Actuator disk theory relates the pressure drop across the disk to the change in wake size and the energy which can be extracted from the wind.  2, record 27, English, - actuator%20disk%20theory

At these high altitudes advective currents and prevailing winds can transport these pollutants vast distances very quickly.

For those wind machines that have a circular cross section, the rotor diameter is determined by measuring from the center of rotation to the tip of the blade and multiplying by two. Rotor diameter is usually associated with horizontal axis machines, but the term also has meaning for the vertical axis machines. In case of a Darrieus, the rotor diameter is the maximum dimension in the horizontal plane that is projected to the wind.  3, record 52, English, - rotor%20diameter
