风对赛艇等户外静水项目有利赛道选择的影响

摘要

The 10 min wind data from two automatic meteorological stations at the Olympic Rowing-Canoeing Park in Rizhao are used to determine the favorable track under different wind conditions. Research results show that when the wind speed is less than 3 m/s, there is little effect on the choice of tracks; when the wind speed is higher than 3 m/s, the water track near the windward side maybe become favorable; when the wind speed is higher than 6 m/s and stability, the flat-water sport events cannot be hold. The results can be used as a basis for referee groups to choose the favorable water track.%利用山东日照水上运动训练基地奥林匹克水上公园静水赛道两岸自动观测站近两年的逐10 min最大风实况数据,对两岸风向、风速的变化特征进行了对比分析.结果表明,水面对风的加速作用使赛艇、皮划艇等水上静水项目的比赛需要根据不同风况设定或调整有利赛道次序,并给出了弱风环境下的赛艇、皮划艇等静水项目比赛,根据不同风向风速判断和选择有利赛道的方法.研究得出:沿赛道走向,顺风、逆风或侧风风速小于3 m/s时,风对有利赛道的选择影响不大；侧风风速稳定大于3 m/s时位于水面上风方的赛道可依次设定或调整为有利赛道；而在风速稳定大于6 m/s时,静水项目的比赛可能无法正常进行.分析结果可为此类水上赛事裁判组制定和调整有利赛道提供依据.
