Initial data
A constant creaking sound was heard by an eyewitness from the city of Shidam:
The screeching continued, it couldn't have been the wind, because I had never heard this sound before. I can't describe it any other way than a beep and/or a separate alarm/warning.
Original news
Aanhangend piepend geluid
SCHIEDAM, ZH — De piepend geluid bleef aanhangen, het kon geen wind zijn want dit geluid heb ik nog nooit gehoord. Ik kan het niet anders verwoorden dan piepend en of een hele aparte alarm/waarschuwing
Hypotheses
The wind
Wind — flow of air, which quickly moves parallel to the earth's surface.
Wind is the result of uneven distribution of atmospheric pressure and is directed from areas of high pressure to the low pressure zone. Due to the continuous pressure changes in time and space speed and wind direction are constantly changing. With height wind speed varies with the decrease of the friction force.
Winds can affect the formation of the relief, causing Eolian deposits that form different kinds of soils (e.g., loess) or erosion.
