wx station wind directions

[LongRanger]

How do various current wx station models handle normally-varying wind directions? Do any update the direction display many times per second? Many models display what the wind direction happened to be when that instrument was last queried.

As most here probably know, air does not always move in a straight line. A real-time wind vane will show the direction changing frequently, for example, anything from W to N, or even beyond, when the average direction is NW.

To learn, I acquired a low-end station because the maker was practically giving them away. When I know the predominant direction to be NW, this unit sometimes displays S or E or others because the wind happened to swirl a bit when the vane was last queried. A few seconds later, the next query might return a very different direction. It's basically useless for determining the predominant direction. Some better stations quote a 2-second sampling rate, which seems too low to me, perhaps because I am used to a wired, real-time vane.
