Unit for Wind Run with speed m/s

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Unit for Wind Run with speed m/s

Post by HansR »

I have added Wind Run to my graphs. However according to to the wiki : Wind run is calculated by adding in a minute's worth of 'distance' corresponding to that speed.
If the speed is in km/hr the distance would be in km, for kts it would be knots (kn) and for mph it would be miles (mi). Is that correct?
But how is the distance recorded for m/s. I assume it is in km. Is that correct?

Yes, in Scandinavia we use m/s for wind speed and km for distance.

Being picky, if the speed is knots, then the distance is nautical miles (M, NM, or nmi).

I missed this, otherwise I would've mentioned it. You're not being picky - just factual. 1 knot is 1 nautical mile per hour, so distance will definitely be nautical miles.

@sutne: OK, thnx. (and I'll change the graph accordingly ;)
@mcrossley: true, my bad. As I use mi for the landmile, I'll start using nmi for the nautical mile. But does CMX actually do store those figures or is there an internal conversion (like there is for m/s)

Cumulus stores the wind run (and lightning distance) in km, mi, or nm
