[QUOTE="Bart B, post: 737362, member: 5302"] Recently got confirmed that wind speed varies with height above ground as well as the terrain type it's blowing across. Here's a table showing the wind speeds above the line of sight and where two cartridges' maximum ordinate is for a mph wind 15 feet above the LOS. [img]http://farm9.staticflickr.com/8178/8029408404_bdcc406050_z.jpg[/img] If you look at the trajectory path of a bullet, it spends only about 25% of its time at the top of its arc where wind speed's the fastest. 50% of its time in the middle wind speed range and about 25% in the lowest speed range. I don't think any ballistic software corrects for the different wind speeds above the line of sight. [/QUOTE]
