===Impact of gusts on pitch | ===Impact of gusts on pitch stability=== | ||
Gusts are brief fluctuations in wind strength and direction. One problem is that gusts can sometimes occur very unexpectedly, even if there was almost no wind a short time before. Moreover, they are typically invisible and therefore difficult to predict. Often it only takes a few seconds before the blast is over again. There are many reasons for this: it can be turbulence, wind shear, vortices, wakes, etc. . The spatial extent of this disturbance can vary by orders of magnitude. | Gusts are brief fluctuations in wind strength and direction.
