The basic advantage of the downwind machine is thus, that it may be built somewhat lighter than an upwind machine. The basic drawback isthe fluctuation in the wind power due to the rotor passing through the wind shade of the tower. This may give more fatigue loads on the turbine than wit...
Downwind is the opposite of upwind, so instead of tilting the rig back, bring it forward and across the board, opening out the sail slightly. Hold the position until you're on course then bring the rig back to the sailing position. Is windsurfing difficult? Windsurfing can be a very diffi...
One plant was infested and placed upwind and the others were uninfested and placed downwind. The downwind plants were later exposed to the cutworm caterpillar. The results showed that plants that had previously been near sick neighbors were able to defend themselves better against the caterpillar. ...
A typical course starts from downwind side to upwind side, and goes around a mark (buoy) set up upwind side, and race to the downwind mark or finish line. The number of legs (between marks) and the position of the marks can take many forms depending on the race. ...
If one specifies the lift to drag ratios of the air-foil (sail) and water foil (keel) than that does indeed bound the upwind and downwind performance of the vehicle. Because there is not theoretical limit to these ratios, there is no theoretical limit to the upwind and downwind performance...
The sudden, abrupt, and unexpected absence of wind in a restricted area is not rare and happens all the time. Disturbed airflow zones are more frequent downwind of obstacles. The wind shadow results from the objects obstructing or creating turbulence upwind of the wind flow, including: ...
This is usually an upwind downwind style course, but it really depends on the race director and the weather on the day as to how it works. The event will feature 20 men and 20 women competing in races up to four times a day, battling winds that will range between five to 4...
Orographic rainfall is rain that is produced from the lifting of moist air over a mountain.The moist air rises and cools, producing orographic clouds, which are the source of the rain. Most orographic rain falls upwind of the mountain range, with some also falling a short distance downwind. ...

Anderson examines housing values and shows no difference in values upwind and downwind of highways, so there is no obvious evidence of non-random sorting of people into upwind and downwind houses. Air pollution Use of Modified Equation to examine the stability of upwind scheme USE OF MODIFIED EQU...
