Re: Wind barbs

In the attached image in a planning route it shows an option for the wind barbs. I don't understand the three options. Shouldn't the options be "to" and "from" as in the wind is blowing "to" or the wind is blowing "from"? The "north up" does not always coincide with the way the particles are moving but seems to be the closest. Could you explain these three options?
It would be extremely helpful if the little white dot on a route was a wind pointer instead. I use an web site "DeepZoom" that has that feature. But they only use the GFS weather model.
