Could anyone be so kind to tell me if the direction my Anemometer is correct
or not ? I mean judging by the direction of most of the wind gusts today it looks more like SE / E but is this correct or not. I guess the Anemometer should point south is this correct ? -- Adrian www.vengaboy.plus.com |

Find the station nearest you at this site:- http://www.xcweather.co.uk/ then compare over a period. Gust directions won't necessarily be from the *mean* direction (as on this site), but it will give you a good idea: Depending upon your height, the obstructions in the vicinity etc., the direction may fluctuate wildly near convective activity.

I mean judging by the direction of most of the wind gusts today it looks more like SE / E but is this correct or not. I guess the Anemometer should point south is this correct ? Several points here Adrian. Looking at your wind direction graph for today the direction has been between NE and SE. The anemometer may have been wrongly set up in the first place. First of all you need to check using a compass so that directions are known, a long stick to keep the wind vane steady and then see how this known direction relates to what is shown on the display. You may/may not then have to re-set the wind vane either at the business end or by rotating the pole. All this assumes that the wind vane is in a safe and accessible location. What you will probably find is that the wind vane is set properly but you are experiencing the effect of urban topography causing a channelling effect on the local wind direction. I noticed this with my setup some time ago but despite checking all the settings and an even higher pole I still get directions which are a little too clockwise. BTW you will probably need an assistant at the console end to help you with checking/resetting, a mobile phone at each end and just make sure you don't fall off the roof.
