Measuring peak wind gusts


wxdudemike

Recommended Posts

I've had an Oregon Scientific wx station for several years now and have always had one problem with wind gusts.  It never measures them high enough due to its long average time.  (It takes a 16+ seconds average I believe)  Now i don't have an excellent area to measure the wind at the appropriate altitude so I understand I may not ever be measuring gusts of 60 mph.  However, it would be nice to have something that doesn't average out the higher wind gusts that do occur. 

 

Does anyone know of any non-budget breaking wx stations that measure peak gusts in a relatively low sample rate?  The problem with 16 second averages is that a gust to 40 would come back significantly lower as it is highly likely the wind will calm down for the majority of the remaining "sample" time.  Does the Davis VP2 (or any others) offer a better peak gust measurement?

I know the VP2 sample rate is 2 seconds. I couple mine with Cumulus freeware and I set it to automatically tabulate and record the peak gust and 2 minute average (ie. sustained). It also uploads that info to WU/CWOP. 

 

That sounds much better.  So you are able to capture (what seems to be) fairly accurate actual peak wind gusts with that?

Yes, I believe it does. The station always reads within good reason of what I experience.  Like any mechanical anemometer there is a slightly noticeable 1-2 sec spin up lag if you watch extremely closely  on a big gust. But, outside of a $$$ sonic, this is the best you're gonna get.

They don't sell the anemometer separately do they? I would rather not buy a whole new station...but I guess I might have to if I want the gusts measurement.

No. You might want to consider getting the Davis Vantage Vue. It has the same anemometer components as the VP2 and I've seen no degration in quality/precision between the VP2 and Vue. The only drawback to the Vue is that it doesn't have extra ports for Solar radiation/UV or other probes. In essence, the vue is a self contained package using the same instruments as the VP2.

 

Either way, if you end up going with Davis for your new station, I highly suggest you buy it from Scaled Instruments they are a re-seller with factory prices and always have had great service and value with them. I always email the owner with my order and ask for the discount price.

Awesome! Can the anemometer be mounted separately?

Not with the Vue. The vue takes all it's obs where you mount it. The VP2 does have a 10m cable (telephone wire essentially) that you can separate the radiation shield/ rain gauge from the anemometer. If you need more than 10m there is a wireless option (extra $) that can operate within 300m of the main station.
