WIND MEASUREMENT IN THE TRACK EVENTS

 

WIND MEASUREMENT

Ø  All wind gauge equipment shall be manufactured and calibrated according to international standards.

 

Ø  The wind gauge for Track Events is placed beside the straight, adjacent to lane 1, 30m (50m and 60m races) or 50m (100m, 110m and 200m races) from the finish line. The measuring plane shall be positioned 1.22m ± 0.05m high and not more than 2m away from the track.

    

Ø  The wind gauge may be started and stopped automatically and/or remotely, and the information conveyed directly to the competition computer.

 

Ø  periods for which the wind velocity shall be measured from the flash / smoke of the Starter’s gun are as follows:

 

 

 

wind gauge operator                                wind gauge operator near by track

The measuring plane shall be positioned 1.22m ± 0.05m high and not more than 2m away from the track.

50m                                    5

50m Hurdles                      5

60m                                    5

60m Hurdles                      5

100m                                  10

100m Hurdles                    13

110m Hurdles                    13

Ø  In the 200m event, except for races on a 200m Standard Oval Track, the wind velocity shall normally be measured for a period of 10 seconds commencing when the first athlete enters the straight.

 

Ø  The wind gauge shall be read in meters per second, rounded to the next higher tenth of a meter per second, unless the second decimal is zero, in the positive direction (that is, a reading of +2.03 meters per second shall be recorded as +2.1; a reading of -2.03 meters per second shall be recorded as -2.0). Gauges that produce digital readings expressed in tenths of meters per second shall be constructed so as to comply with this Rule.
