Good information, Lancermania. However, I take that adjustment calculator with a grain of salt. As an engineer who has some basic knowledge of fluid mechanics, of which the movement and forces involved with the movement of air on an object (i.e., runner), there is no way to effectively evaluate the influence (time-wise) upon a runner to an exact amount. The force imparted on an object by a steady-state wind (constant velocity & direction) is directly proportional to effective area profile of that object with respect to the wind. Given that arms & legs are changing direction over 4 times/second during the course of a run in a sprint, it is difficult to create a reasonably accurate area profile that the runner provides with respect to the wind.
That said, Mureika's work may be the only current source that provides a reasonable assessment of the wind's influence upon a runner.
What is more problematic is the methodology by which wind readings are made. They in effect averages calculated over the course of a run/jump in direction of the track/runway. It gives no information with regard to the variability of the wind/direction over the course of the event. For example, stadiums and other objects (trees, buildings, etc.) create varying wind speeds and direction that influence runners/jumpers, and frequently, quite substantially. Welcome Stadium, Ohio Stadium, Jesse Owens Stadium are prime examples where the winds can vary greatly depending upon where you are in the stadium at any given moment. Ohio & Welcome Stadiums were notorious for their massive headwinds on the backstretch given the relative North-South orientations of those stadiums with their start/finish lines being near the southwest corners of the stadium. Likewise, frequently one would see a strong tailwind (from the north) near the early stages of a 100m/110mH/100mH in those stadiums, while the wind would drop off during the latter part of the sprint. IUPUI's facility (a West-to-East orientation) in Indianapolis where FloJo set the women's world record of 10.49 (of which I had the fortune of being there in person to see that!) had a situation where the official reading of +0.0 wind was confirmed despite the fact that winds upward of +5 mps were being recorded on the nearby triple jump runway. That facility, having been there many times myself, has a lot of swirling winds nearer the east end of the facility as you get nearer the grandstand and away from the open east end of the stadium. Stadiums and objects near them affect winds quite profoundly at times depending on the direction of the wind at any given time. For anyone who has flown airplane or other aircraft (as I have), they will tell you that when coming into a landing situation, wind variability can be quite profound when you get near the ground where buildings and other objects disturb the wind that one sees just a few hundred feet higher. In fluid mechanics terms, laminar air flow (constant speed/direction) becomes quite turbulent upon the introduction of objects (buildings, etc.) near the ground.
While quite long-winded, I hope this helps those who haven't thought about the subject much as to the nature of influence of wind upon athletic performances and how variable it can be. This also applies particularly to the discus & javelin throws where the wind can and does have profound influences upon the flight of the implement. Same thing goes with the pole vault where vaulters have to account for wind direction/speed when vaulting.
Anyway, you all have a good day!
