Have decided to go with just the Top 20 from last years thread with different points scoring. The points will be whatever the minimum is so say Aboyne gets -6.0C they get -6.0 points, the highest negative points at the end of the trial will win, OR if there are no negative points at the end the station with the lowest points per se wins. However theres a twist! Maximum temperatures are also included to deduct points so if Aboyne then had a max of 2.0C then their score goes to -4.0 points.
First day of activation will be when the first of the 20 stations have an air frost, then scoring commences for that day for everyone, min and max temps used. Thereafter if no station gets an air frost then no points awarded and only if one station or more gets an air frost then the rest are scored accordingly, for that day.
The end will happen when the group has its first No Air frost day after 1st April 2012
Will be using Ogimet and the UKMO for temperatures. Below is an example of the table, the figures are ficticious, however the 20 stations on there are the stations i will be using as they were the top 20 from last year, and it makes my life easier, hopefully. We now await the 1st air frost from one of the 20 stations
Any questions please ask
