The reference wind pressure q {\displaystyle q} is calculated using the following equation: q = 1 2 p v 2 {\displaystyle q={\frac {1}{2}}pv^{2}} where p {\displaystyle p} is the air density and v {\displaystyle v} is wind speed. For the purposes of this model, the wind speed in the first 1000 or so feet is the most important, since this is when the rocket is most vulnerable to the destabilizing effects of the wind, but it would of course also be great to model wind during the rest of the flight as accurately as possible. Go to the U.S. Wind Climatology site and use the pull down menus to select a year and month. For each month and parameter, the tool shows the climatological mean wind (average over the previous three decades), observed winds, and wind anomaly (how much faster or slower wind blew compared to the long-term average for that month). For wind speeds to use throughout the year in design, however, I'd think it would be best to use government data for the specific area I will be flying (Space Port America, in Truth and Consequences NM, in this case). There are two presentation styles used to convey wind speed and direction. Marlene; Dec 15, 2019; I gave the CD as a birthday present.
