In Yowindow, the wind is measured in meters per second, kilometers per hour, knots etc.. depending on the chosen scale. When there is no wind, it seems CALM (Calmo in Italian).
Yowindow is a fun program for to spread the passion for meteorology, science and astronomy.
Since the data come from Yowindow METAR from YR.NO and many other stations PWS it is also a professional.
Why not show,(*) along with wind speed, the number on the Beaufort scale, (from 1 to 12) universally accepted by January 1, 1949, and the description of the wind (calm, light air, light breeze, gentle breeze, etc.).?
And why not add the name of the state of the sea ?

(*)(No hurry, when you lower the fever for lanscapes...)
