In the January issue of the Bulletin of the American Meteorological Society (BAMS), I came across an article addressing the forecasting needs for outdoor sports venues. The article states that NCAA has a rule dictating a delay in game play (perhaps only for football) if lightening occurs within 6 miles of the venue.
Since the AMS is quite comfortable with and competent in using metric units, I doubt very much that this is a case of the NCAA saying "within 10 km" and the AMS converting it to "within six miles". But I do wonder if the NCAA rule arose from lightening studies that suggested a 10 km danger zone centered on the last strike and the NCAA converting this to six miles. Any NCAA experts out there? Anyone wishing to dig into the NCAA rulebooks and tracking down their sources? Jim -- James R.
