杭州亚运会皮划艇和赛艇项目气候背景分析

Climatic Background Analysis for Canoeing and Rowing Event in the 19th Asian Games Hangzhou 2023

  • 摘要: 利用杭州亚运会北支江水上运动中心场馆附近的气象观测站2010—2021年逐日和逐小时气象观测资料,对场馆9月23日—10月8日的天气气候特征进行分析,并对赛艇、皮划艇赛事进行气象条件适宜性分析。结果表明:1)亚运会期间会对比赛成绩影响较大的气温出现频率较低,从气温角度看,赛事适宜安排在08:00—11:00和17:00—20:00;降水概率较大,每2~3 d就会出现1次降雨天气,但以小雨为主。2)亚运会期间会对比赛项目产生影响的大风天气出现次数较少;逐小时平均风速在13:00—16:00较大,建议将受风影响较大的比赛项目尽量安排在风速相对较小的上午或傍晚。偏北风为水上运动中心最多风向,偏东风次之;15:00—18:00风向摆动角度最小,从该指标来看,水上运动赛事适宜安排在15:00—18:00。3)日平均人体舒适度指数在9月下旬为舒适或偏热等级,在9月末到10月上旬为舒适等级;人体舒适度达到4级的天数最多,3级的天数次之。4)综合赛事各项气象条件分级指标来看,赛艇项目和皮划艇项目最适合开展时间为08:00—09:00,其次为10:00和17:00—20:00。

     

    Abstract: Using the daily and hourly observational data of the automatic weather station near Beizhijiang water sports center from 2010 to 2021, the climatic characteristics of the venue during 23 September to 8 October 2023 are statistically analyzed to identify the suitability of meteorological conditions for rowing and canoeing events. Research results show as follows: (1) The occurrence frequency of temperature that will have a great impact on canoeing and rowing performance is low. From the perspective of temperature, it is suitable to hold the events at 08:00-11:00 BT and 17:00-20:00 BT. It is rainy in every 2-3 days, but it is mainly light rain. (2) There will be low occurrence frequency of gale weather that will have a great impact on performance. The wind speed is high at 13:00-16:00 BT, so it is recommended to arrange the events greatly affected by the wind in the morning or evening. The dominating wind direction is the northerly, followed by the easterly wind. The smallest wind swing angle occurs during 15:00-18:00 BT. Therefore, from the perspective of wind swing, the time period of 15: 00-18:00 BT is the proper choice for the water sports. (3) The daily average human comfort index is comfortable or slightly hot in late September, and comfortable from late September to early October. The number of days when human body comfort index reaches level 4 is the highest, followed by level 3. (4) Based on the overall analysis of the meteorological factors, the most suitable time for rowing and canoeing is 08:00-09:00 BT, followed by 10:00 BT and 17:00-20:00 BT.
