Power of atmosphere and skyscraper windows?

    Power of atmosphere and skyscraper windows???

    Hi i was wondering about a question dealing with atmosphere and windows....If you could help me out by understanding somethings id really appreciate it..thanks alot...


    In a large cities when wind is forced to blow between two rows of skyscrapers, windows in the skyscrapers are sometimes blown outwards. Why does this happen? Is it something with the atmoshpere and pressure of air??

    You are indeed correct. The air passing over the outside of the window causes a decrease in pressure leading to a higher pressure inside the building compared to outside, thus forcing the glass outwards.

    Doesn't the wind increase dramatically in speed when it's forced through the narrow gap between two buildings, thus increasing the pressure difference?

    I'm not entirely sure whether that is the case, but it certainly would make sense, intuitively.

    Heh, I'm just going by something I heard on a Discovery show, though, heh, so the OP should take it with a grain of salt. ^^;
