title: [Geostrophic deviation analysis of regional effects of protective forest system in reducing windspeed in north Liaoning plain].
abstract: East Asian synoptic charts and ground wind data in April and May of four counties of north Liaoning plain were selected to calculate the regional effects of protective forest system in reducing windspeed by geostrophic deviation method. The results show that the protection effects increased with increasing forestration area. Different protection effects of protective forest appeared at different daytime, with the greatest at 14:00 and smallest at 2:00, and the average windspeed reduced 13.3%. The characteristics of the geostrophic deviation method was also discussed.
