Abstract
We suggest a procedure selecting the optimum size of narrow snowbreak woods. The procedure involves examining the following items in this order:
1) Snowbreak effect in relation to planting conditions and tree height
2) Setting of quantitative targets for controlling blowing snow
3) Calculation of cumulative frequencies of visibility and wind velocity
4) Conditions for installation of narrow snowbreak woods
We demonstrate that the conditions for effective installation of narrow snowbreak woods can be determined through knowledge of the maximum wind velocity and the frequency of poor visibility (less than 200 m) in the survey area.
