The distance to which a vessel is carried off from her desired course by the wind, currents, or other causes.
One of the slower movements of oceanic circulation; a general tendency of the water, subject to occasional or frequent diversion or reversal by the wind; as, the easterly drift of the North Pacific.
To accumulate in heaps by the force of wind; to be driven into heaps; as, snow or sand drifts.
To drive into heaps; as, a current of wind drifts snow or sand.
That causes drifting or that is drifted; movable by wind or currents; as, drift currents; drift ice; drift mud.
Slow systematic movement in the same direction.
The speed (in knots) at which the current is moving. Drift may also be indicated in statute miles per hour in some areas such as the Great Lakes. This term is also commonly used to mean the speed at which a vessel deviates from the course steered due to the combined effects of external forces such as wind and current. With external inputs, such as heading devices and speed logs, many EPFS units and ECS can determine experienced set and drift.
1. The leeway of a boat; 2. The natural direction of movement of a boat caused by wind or current, when the boat is not under power; 3. The speed a boat is pushed sideways while under power; 4. The speed of current in knots; 5. To move along with the tide or current
When the wind blows loose snow over the surface. It generally happens when the wind is stronger than 15 knots. When the wind is stronger than 20 knots there will be snow up to head height and the visibility is seriously reduced.
The movement of airborne spray or dust particles outside the intended contact area.
(of baseline in a chromatogram) may be caused by movement of the stationary phase into the mobile phase.
Pesticide movement in air, away from the target site.
Pertaining to the movement of teeth. This movement is uncontrolled and irregular.
In ballistics, movement of a bullet to the left or right of a straight line connecting the gun muzzle and the target. Windage designates drift caused by wind pressure. Ballistic drift is caused both by the bullets tendency to rotate on the air and by the precessional rotation of the bullets nose around the trajectory's curve, the latter being a gyroscopic phenomenon
the sideways movement due to the action of the wind on the kite.
something that is heaped up by the wind or by water currents
a general tendency to change (as of opinion); "not openly liberal but that is the trend of the book"; "a broad movement of the electorate to the right"
be in motion due to some air or water current; "The leaves were blowing in the wind"; "the boat drifted on the lake"; "The sailboat was adrift on the open sea"; "the shipwrecked boat drifted away from the shore"
cause to be carried by a current; "drift the boats downstream"
be piled up in banks or heaps by the force of wind or a current; "snow drifting several feet high"; "sand drifting like snow"
A deviation of the system from setpoint that typically occurs over a long period of time. Drift may be caused by such factors as changes in ambient temperature or line voltage.
The portion of spray that is not deposited within the target area.
Pesticide movement off the target area due to air currents.
Letting your spray get where you don't want it, usually because of wind or poor application technique.
Effect of wind on smoke, retardant drops, paracargo, smokejumper streamers, etc.
The deviation in flight of a bullet from the center line of the bore due to the gyrational spin of bullet imparted by the rifling.
Lateral movement of a bullet away from the line of bore, caused by its rotation on its axis, in the direction of the rifling twist. With airguns, drift is not a significant value.
a movement of the specimen during the exposure time, which causes a blurring of the image. It leaves a characteristic signature in the diffraction pattern, from which the type, the direction, and the extent of the movement can be inferred (Frank, 1969).
the leeway, or movement of the boat, when not under power, or when being pushed sideways while under power the speed in knots, of a current.
The physical movement of prohibited substances from the intended target site onto an organic operation or portion thereof. Drip/trickle irrigation. Watering plants so that only soil in the plant's immediate vicinity is moistened. Water is supplied from a thin plastic tube at a low flow rate. It is the most efficient use of water for irrigation and also reduces the chance of pathogens because the entire plant is not wetted, thereby denying moisture to the microorganisms.
Movement of a boat due to wind and current; velocity (speed) of current.
the leeway, or movement of the boat, when not under power, or when being pushed sideways while under power ase - to loosen or let out airlead - a fitting used to change the direction of a line without chafing
the movement of a pesticide (which may be applied as a spray, a fine granule or in another form) outside the target area due to air currents.
The airborne movement of a pesticide spray or dust from the target area to an area not intended to be treated.
Unwanted movement of teeth.
The inability for a kite to keep on a straight line, or in buggying and kite-surfing, the sideways pressure due to the action of the wind on the sail.
(1) Floating or non-mineral burden of a stream. (2) Deviation from a normal course in a cross current, as in littoral drift.
Pesticide that moves out of the treatment zone or is off target.
The varying amounts of adulticide spray which is lost to the targeted area because of the effects of wind. (See Adulticide).
The movement of airborne particles by air motion or wind away from the intended target area.
The lateral movement of a projectile due to rotation in flight through the atmosphere. If the gun has rifling with a left hand twist, the movement will be to left and vice versa, OR, The lateral movement of a projectile due to wind.
sideways movement of the ball through the air on its flight towards the batsman when bowled by a spin bowler, may be caused by differential airflow around the spinning ball and/or the wind. v.t. to achieve some drift with the ball. The bowler drifted the ball in to the batsman.
Deviation from a course caused by crosswise currents of air.
The movement of particles or droplets through the air from the area where it is being applied to locations outside the targeted area. Through drift or runoff, pesticides can affect more than just the crops it is intended for. Organic crops must use buffer zones to help guard against drift.
A reference to the impact of the wind on the spreading of dry fertiliser products.
The crabwise motion of an aeroplane over the ground due to a side wind; also used to denote head resistance
In exterior ballistics, the deviation of a projectile from the line of departure due to its rotation or spin. Also commonly but incorrectly applied to the effects of wind. See wind deflection.
A term applied to either a natural developmental phenomenon (mesial drift) whereby the posterior teeth continually move slightly forward as the interproximal surfaces wear or where contiguous teeth are missing and there is movement into that space.
The movement of a portion of airborne particles of a dust or spray away from an intended point of application.
