Fig. 1: 100 m performance changes with ambient weather conditions.

Relation of 100 m finishing time anomaly (unit: second) with (a) the ambient temperature anomaly, (d) tail wind speed anomaly, (e) atmospheric pressure anomaly and (f) relative humidity anomaly using rcs-GLM. 988 competition results of the current world-top 20 men and 20 women competitors with valid values of meteorological variables are used for obtaining the relation. The shadings denote the 95% confidence interval. b, c As in (a), but for the 499 results of world-top men and 489 results of world-top women competitors, respectively.
