The control experiment used large scale fields of the interval February-October 1995 (the winter of 1995-1996 had a strong negative NAO/AO phase). Firstly, we remove the snow cover over the key region in Southern Siberia in the interval February-July.

    Then, the snow amount:
  1. A.is left to melt itself normally, with melted snow going in runoff and soil;
  2. B.is totally put in runoff term, without contributing to the soil moisture. 
The same type of experiments are conducted for October, too.
