We can only hear the wind when it hits an object, be it leaves, a dead tree, a steel door,  and so on. How strange is that!

And what when air hits air?
I have been studying a little bit on that issue and it shows that air may hit air, eg. higher up in the atmosphere, resulting in turbulence, which coincides with infrasound in the frequency band of 0.2 to 4 Hz. These sounds may be heard over very long distances. Currently, I do not have a recording system for such low frequencies. Maybe something for a new project.

Sun & Wind - 2019/05/12 - Kloster Muhde

5–8 Beaufort wind on an otherwise dry and sunny day. Testing new windshield and pseudo-binaural setup in our garden. Wind is flowing through the leafless trees, small birds and geese can be heard from time to time. Some cars passing by are almost absorbed by the wind sound......not bad.

Wind & Birds - 2019/12/15 - Kloster Muhde

Second track of the wind blowing ahead of the 'Dennis' storm forecasted for tomorrow. This particular tree was hit by 'Ciara' (UK,NL) alias 'Sabine' (GER) and landed in his neighbour. The sound is different from that of the dead tree. In the third minute a Bussard flies over crying loudly. The stronger wind sounds are from a Douglas fir wood some 100 meters away.

Headphones recommended.

Wind & Wood - 2020/02/15 - Oldehave, Ostfriesland

Peak of the storm 'Dennis' is over. This recording was made in Emmen (NL), Emmerdennen near Haantjebak with 30m above sea level the highest point in the province Drente. Wind is strong and comes in long waves that sound like if an air-jet is passing by. The rumble is made by leafless branches of trees, mainly beeches. Different species of small birds are singing.

Headphones recommended.

More wind - 2020/02/16 - Haantjebak, Emmen, NL

This is my last recording covering the storm 'Dennis'. Sustrum Moor lies in the former Bourtanger Moor. This moorland formed a natural border between the Netherlands and Germany for over thousands of years. All peat has been removed during the last 150 years and the remaining landscape is flat and empty. Soils are sandy and of low fertility. They are used mainly for non-food crop farming, animal feed and intensive livestock production (pigs & poultry). Also you will find many wind-parks in this region. It was difficult to make the recording, the only hide I had was behind the car. I tried behind the mill but was literally blown away...no chance. 
Listen how the blades of the mill cut the storm in slices...

Headphones recommended.
