What is wind run?

Can someone give me an easy explanation of what WIND RUN is and how it relates to how much wind energy that can be created?

Hi,

Did a search on Wind Run and came up with this topic.

Hope this helps some.

According to Davis:

Wind run is measurement of the “amount” of wind passing the station during a given period of time, expressed in either “miles of wind” or “kilometers of wind”. WeatherLink calculates wind run by multiplying the average wind speed for each archive record by the archive interval.
For Example:

Average Wind Speed = 5 mph
Archive Interval = 30 minutes (0.5 hours)
Wind Run = 5 mph x 0.5 hours = 2.5 miles of wind

think of it like the odometer on your car

My question is “what does it mean?” or 'what is it telling me?" What is the measurement used for or what does it indicate? Is it a measurement of energy? Is it a way of comparing windy days - eg: Day A might have higher wind speeds but only for a short time, but day B may have lower wind speeds over a longer period of time, and therfore day B may actualy be more windy than A.

the wind enery is more usefull for that type of comparisons
see under view, wind energy

My explanation to others is:

“Assuming the wind blows in the same direction all day, if you were to fart outside at midnight, the windrun tells you how far away it would be 24 hours later.”

Is that about right ?

Ian,

That is correct!

However, must be one heck of a fart if it were to smell all the way… :smiley:

A more technically correct description might be “an integration of wind speed over time” (but definitely not “the integration of wind velocity over time”.

Ian

Love it!

“How far it would have travelled” would be more correct. Just think, with a change in wind direction you could get it back :lol:

Nice. Hate to see that 180 degree shift.

Wind Run - Wind run is the total distance that the air has traveled past a measuring point during a 24 Hr period. For example, a wind run of 200 Km measured at 6pm means that a ‘length of air’ 200 Km long has past the measuring point from 6pm the previous day to 6pm on the day of the measurement.
In the area that I live in it is used to tell how much electricty that the wind turbins can make.

Whow------- Now if the average wind speed going past my station = 35 mph and the archive interval = 24 hours that means the wind run = 35 mph X 24 hours = 840 miles of wind and if the station next to me is at a distance of 30 miles to the North and has a wind speed of 5 mph. he is in for one big pile of wind at his door step. 8O

Man, if you do this wind run thing for 24 hrs. and the wind is constantly changing from 5 mph. to 30 mph. with gusts up to 70 mph every 3 to 9 min. Your going to burn up your station with all of the calculations. #-o

How do you mark the wind, so you know where it starts and stops. :greenjumpers:

Imho, the suggestion by windy to compare it to the odometer in your car is clear enough :roll:.

:big4:

Some one swat that bug :slight_smile:
