摘要：

Wind discomfort criteria are compared and optimised using a U/U-pot framework; U-pot is the 10 m wind speed at an ideal meteorological site. A new estimate of turbulence intensity is proposed for the conversion of criteria to a U/U-pot ratio. Using this estimate, differences between existing criteria turn out to be much larger than remarked upon in the past. The criteria are also checked against empirical evidence. For the test case of Amsterdam, the maximum recommended value of U/U-pot varies between 0.3 (for sitting) and 0.7 (safety only). Optimum thresholds are proposed as well.
