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.
