<div>I have a script that pulls wind speed and direction out of selected METAR files, and I would like to plot wind barbs from this data within GrADS. However, when I 'set gxout model', and 'd spds;dirs' - I get wind barbs that are either out of the south or west (depending on which I put 1st, spds, or dirs), and the magnitude of the wind barb is actually drawn up as the wind direction. So earlier today when I tried to make this plot, I all of my sites were showing wind out of the west at 200-250 knots (wind direction was varying from 200-250, with speeds around 10 kts). Is there a way I can use the data I am pulling out to plot wind barbs that are representative of current conditions, or is there a way that I can calculate the individual u and v components of the wind at each of my points for a given wind speed and direction? I've yet to come across a formula to break a wind speed and direction into individual components, so if this could be done and someone knows how to do so, I'd appreciate it!
