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 ...

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".
Tunahawk is correct. In the US, "upwind leg" properly is *not* an alternative term for departure or climb out because it is in-line with the runway and below TPA. Strictly speaking, Departure is no more upwind than is final. Upwind is the opposite of downwind, both of which are at or near TPA and parallel to but offset from the runway.
An overhead join is a conventional method for an aircraft to approach and safely land at an airfield. It helps a pilot to integrate with any air traffic pattern near an airfield, join any circuit, and land.
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 ...
Just before the flare, opposite rudder (downwind rudder) is applied to eliminate the crab, with a simultaneous application of opposite aileron to maintain a wings-level attitude, so that at touch down, the body, velocity vector, and bank angle are all aligned with the runway, and the aircraft is positioned near the center.
For instance, if a vessel sails alternately in the directions 45° from the downwind direction, it will sail √ 2 (≈1.4) times farther than it would if it sailed dead downwind. However, as long as it can sail faster than 1.4 times its dead downwind speed, the indirect route will allow it to arrive at a chosen point sooner.
