Not sure if anyone has any data, but if windspeed seriously affect internal air pressure, a couple of barometers could pick up this difference. I have a barometer on my landing, I could look at that and compare it to the one from the local weather station (if I can find that data). I would expect it to be sightly lower when it is very windy.
I decided to have a look at the data from my house.
I worked with half hour means, corrected for altitude and sensor difference, worked out the anomalies, took one from the other and plotted the results against windspeed.
The higher the pressure difference, the lower the internal air pressure is.
There is a lot of variation below 4 ms-1
but after that the difference is more pronounced.
Here is a picture of the very weak correlation.
