Anemometer problem and a storm coming
There’s been a recurring issue over the past few days witn the wind data dropping out from the Ski Club Hut automatic weather station on CairnGorm Mountain.
The intermittent rather than constant nature of the problem suggests a poor connection and/or damaged wiring is to blame. The anemometer has functioned when temps have been lowest, suggestive that water ingress into the AWS unit might be a contributing factor.
Weather permitting if the forecast lull does indeed come over during Saturday the Weather Station will be taken apart and checked out, connections cleaned out, cables checked and hopefully it will function OK given the predicated storms. The weather station will if time/weather allows also be switched over to cable link rather than radio link which should improve reporting of stronger gusts due to more frequent sampling.
The mariginal nature of the snow event at times though means the likelyhood of wet driving snow for a time at the SSC Hut level which greatly increases the potential risk for anemometer icing. If anyone has a couple of grand going spare for a heated sensor array, drop us a line!
