摘要:

利用国内外气象因素对马拉松比赛适宜气象条件、运动员成绩影响及体育赛事活动气象灾害风险等相关研究结论, 设计了马拉松比赛气象指数的评分方法和计算公式, 通过特征要素分类、区间阈值设定和指数等级划分, 构建了指数预报方法。结果表明: 影响马拉松比赛的主要特征要素为气温、降水、风速、湿度、气压、日照及紫外线、空气污染和强对流天气, 计算出的指数等级能够反映气象条件对比赛的影响程度以及首要影响气象条件。马拉松比赛气象指数为一级时, 气象条件最适宜比赛; 指数为二级和三级时, 可能出现对比赛有一定影响的不利气象条件; 指数为四级和五级时, 可能出现对比赛有较高影响的不利气象条件; 指数为六级时, 可能出现对比赛有严重影响的灾害性天气。马拉松比赛气象指数预报方法能够更好地满足“直观反映气象条件适宜度”的气象服务需求, 有效提高赛事气象保障服务的专业性和针对性。

Abstract:

Based on the research conclusions on the suitable meteorological conditions for Marathon races at home and abroad, the impact of weather factors on athletes' performance, and the meteorological disaster risk of sports events, the scoring method and calculation formula of meteorological index for marathon races were designed.Moreover, an index forecasting method was constructed by the characteristic element classification, interval threshold setting, and index level division.The results indicate that the main characteristic elements affecting Marathon races are temperature, precipitation, wind speed, humidity, air pressure, sunshine, ultraviolet radiation, air pollution, and severe convective weather.The calculated index level can reflect the impact of meteorological conditions on the races and the primary influencing meteorological conditions.When the meteorological index for Marathon races is level 1, the weather conditions are most suitable for the races; when the index is 2~3, there may be some adverse weather conditions that have a certain impact on the races; when the index is 4~5, there may be adverse weather conditions that have a high impact on the races; when the index is level 6, there may be disastrous weather conditions that have a serious impact on the races.The forecasting method of meteorological index for Marathon races can provide better meteorological service by "directly reflecting the suitability of meteorological conditions", thereby effectively improve the professionalism and pertinence of meteorological support services for the races.
