Patterns are typically rectangular in basic shape, and include the runway along one long side of the rectangle. Each leg of the pattern has a particular name: [3] Upwind leg. A flight path parallel to and in the direction of the landing runway. It is offset from the runway and opposite the downwind leg. Crosswind leg. A short climbing flight ...
Similarly, if is negative the traveling wave solution propagates towards the left, the left side is called downwind side and right side is the upwind side. If the finite difference scheme for the spatial derivative, ∂ u / ∂ x {\displaystyle \partial u/\partial x} contains more points in the upwind side, the scheme is called an upwind-biased ...
Windward is upwind from the point of reference, i.e., towards the direction from which the wind is coming; leeward is downwind from the point of reference, i.e., along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side".
With other traffic present in the circuit, the aircraft might be positioned downwind in the circuit behind or between other traffic in order to land in turn. Alternatives to the overhead join are to directly join the circuit by entering at a suitable corner, or a straight-in approach.
On very slippery runways, landing the airplane using crab only reduces drift towards the downwind side of a touchdown, and may reduce pilot workload since the airplane does not have to be de-crabbed before touchdown. However, proper rudder and upwind aileron must be applied after touchdown to ensure directional control is maintained.
In central differencing scheme and second order upwind scheme the first order derivative is included and the second order derivative is ignored. These schemes are therefore considered second order accurate where as QUICK does take the second order derivative into account, but ignores the third order derivative hence this is considered third ...

A ship at sea is said to possess the weather gage if it is in any position upwind of the other vessel. [1] Proximity with the land, tidal and stream effects and wind variability due to geography (hills, cliffs, etc.) may also come into play. An upwind vessel is able to manoeuvre at will toward any downwind point, since the relative wind then ...
