Abstract: Based on the probability of exceeding threshold, the wind environment at pedestrian height around the tower and the air traffic control building of Zhuhai Airport, which is located in the southeast coast of China, was investigated by combining the near-field wind speed measurement data and wind tunnel tests. Moreover, the impact of meteorological data representing different levels of near field, district and city on the assessment results of pedestrian wind environment was analyzed. By statistically analyzing the meteorological data of the last ten years monitored by the airport anemometer tower, the wind rose maps under 36 wind angles were obtained and then their Weibull distribution functions were established by curve fitting. The mean and gust wind speed ratios for the 36 wind angles were determined by wind tunnel experiments of wind environment at pedestrian height. The comfort level and danger level were assessed respectively from four and two classes based on the probability of exceeding threshold and Lawson criteria using mean wind speed and gust equivalent mean wind speed. The results show that, compared with the assessments based on mean wind speed, the assessments based on gust equivalent mean wind speed are more likely to meet the assessment criteria, suggesting that the effect of the transient of the flow field is not significant. Except for the corridor between the tower and the air traffic control building and some areas at building corners, most of the monitoring areas meet the requirements for a quick walk at the comfort level, and meet the requirements of non-entry for sensitive persons or cyclists at the danger level. The monitored area at the corridor between the tower and the air traffic control building exhibits a "Venturi effect", in addition, vortex shedding occurs at the corners of the building, which leads to a higher wind speed ratio in these areas. Therefore, it is necessary to avoid setting entrances and main corridors between buildings and at building corners. The closer the meteorological station is to the building, the more accurate the assessment of pedestrian wind environment is, and the impact of distance on the comfort level assessment is more significant than that of the danger level assessment.
