The side labelled 'North' on the wind vane mount should face ''True North'', remember that the magnetic north deviation from true north varies from year to year, see details on maps or online. Most wind vanes have a large surface that follows the wind and a thin end that points where the wind comes from, it is the latter direction that is reported. | |||
In the UK, the standard climatological measuring height is 10 metres. Advice varies on whether you should apply a correction factor for any lower height. Cumulus allows you to apply such a factor to either just wind speed, or wind speed and gust speed, by using the Calibration screen within the configuation menu. In the Cumulus Help it recommends that you also adjust wind chill - in practice this means ask Cumulus to ''calculate wind chill'' by selecting this in the settings frame on the '''station settings screen accessed from configuration menu''' (i.e. ignore any wind chill output by your weather station). | In the UK, the standard climatological measuring height is 10 metres.
