Topic: Wind speed comparison at two sites - a question

[piote]

Hi all,

I'd like to ask your opinion on the issue below. Perhaps you would be able to point to the approximate solution.

We have 2 sites - the first one on the sea (ST1), the second one (situated about 10km away from the first one) on the shore - the shore is covered with a coniferous forest (ST2).

At ST2 there is a sodar, which is able to measure wind speed at various levels above ground. The idea is to find an approximation of wind speed at ST1 using the sodar measurements at ST2. How can this be done? Eg. can we find an approximate height above the ground at ST2 where the wind speed would be comparable to the wind speed at ST1 (the sensor here is situateed 4m above sea level)?

I would expect there would be way too many variables and unknowns to make any assumptions?

What Is A Coffee Maker?

✩ The coffee maker is an invention for people who really love enjoying a good cup of coffee. Coffee is one of the favorite drinks in many countries. As you might know, there are more and more people who prefer having 1 or 2 cups of coffee a day. However, many of them find it complicated and time-consuming to make it in a traditional way. In fact, grinding beans, spooning out the coffee, or boiling the kettle can be a problem for some. That is the reason why the coffee maker was invented. Coffee makers make the process much easier. Furthermore, they can make large quantities of coffee in a short time

I have had dead calm in my front yard while the tops of trees just a few hundred feet away are swaying a lot.

I think the microclimate is so variable that any attempt at estimating wind even a few hundred feet away is a wild goose chase.

On my 80' tower I have three RMYoung 5103s, and in light wind they can be showing far different directions and conditions.  In heavy wind, especially during storms, they are changing a lot.

At airports, the wind given by the tower is often different from what one sees on a wind sock at the end of the runway, too.
