- Headwind and tailwind. A tailwind is a wind that blows in the direction of travel of an object, while a headwind blows against the direction of travel. A tailwind increases the object's speed and reduces the time required to reach its destination, while a headwind has the opposite effect.

Docking (animal) Two lambs having their tails docked by the use of rubber rings for elastration. The tight rubber rings block blood flow to the lower portion of the tail, which will atrophy and fall off. Docking is the intentional removal of part of an animal's tail or, sometimes, ears. The term cropping is more commonly used in reference to the cropping of ears, while docking more commonly—but not exclusively—refers to the tail. The term tailing is also commonly used.

wind wind. n. 1. (Physical Geography) a current of air, sometimes of considerable force, moving generally horizontally from areas of high pressure to areas of low pressure. See also Beaufort scale. 2. (Physical Geography) the direction from which a wind blows, usually a cardinal point of the compass.

Severe Storm Definitions & Whirlwind Classification Vortex, whirlpool and whirlwind. As a preamble, a vortex may be defined as a rotation within a fluid. If the fluid is a liquid, the vortex may be more accurately termed as a whirlpool, while if it is a gas it is termed a whirlwind. Major, minor and other whirlwinds.

Spin (aerodynamics) Spin (aerodynamics) A spin is a special category of stall resulting in autorotation about the vertical axis and a shallow, rotating, downward path. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. In a normal spin, the wing on the inside of the turn is stalled while the outside wing remains flying; it is possible for both wings to be stalled but the angle of attack of each wing, and consequently its lift and drag, will be di

The Jet Stream The Jet Stream. How the earth's rotation the effects the west to east direction of the jet stream. Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blows from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air. Since these hot and cold air boundaries are most pronounced in winter, jet streams are the strongest for both the northern and southern hemisphere winters.

jet stream jet stream. A narrow current of strong wind circling the Earth from west to east at altitudes of 10 to 15 miles (16 to 24 kilometers) above sea level. There are usually four distinct jet streams, two each in the Northern and Southern Hemispheres.

backdraft 2. backdraft. An explosive surge in a fire produced by the sudden mixing of air with other combustible gases. This is caused by a condition in a fire where oxygen is depleted and the fire dies down until a door is opened and the fire flares violently from the sudden intake of oxygen.

Tidal tail Tidal forces can eject a significant amount of a galaxy's gas into the tail; within the Antennae Galaxies, for example, nearly half of the observed gaseous matter is found within the tail structures.

Wind A short burst of high speed wind is termed a wind gust, one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval by 10 knots (19 km/h). A squall is a doubling of the wind speed above a certain threshold, which lasts for a minute or more.

Definitions &Translations A backdraft is an explosive event caused by a fire, resulting from rapid re-introduction of oxygen to combustion in an oxygen-depleted environment, for example, the breaking of a window or opening of a door to an enclosed space. Backdrafts present a serious threat to firefighters.

What are the White Streaks in the Sky? This horizontal tornado is called wingtip vortices and is also termed wake turbulence. Note the word wake in wake turbulence, just like a boat has a wake behind it when moving through the water. Wake turbulence can be a serious hazard to small aircraft landing or taking off after a larger, heavier aircraft.

- Wind shown in red. ① Broad reaching on port tack. Prepare to jibe! ② Bearing away, or turning downwind, and hauling in the sail(s) to begin the jibing maneuver. Bearing away! ③ Heading downwind, the wind catches the other side of the sail and it jibes, then is quickly let out to its new position. Jibe-ho! ④ Steadying up on the new tack.

- In storm spotting, a backing wind usually refers to the turning of a south or southwest surface wind with time to a more east or southeasterly direction. Backing of the surface wind can increase the potential for tornado development by increasing the directional shear at low levels.
