Future predictions for wind Making accurate predictions on how the wind environment may change the future is very difficult. Predictions of the changes in the wind climate are among the least certain of the UKCIP02 scenarios, they do, however, indicate:
The consequences of these predicted are:
However, it must be noted that the magnitude of these predicted changes is generally less than the inter-annual variability that we would expect to occur naturally.
What would be the potential impact of these changes? A slight increase in mean windspeed or a shift in seasonally is unlikely to have an observable impact on woodlands or forestry. The likelyhood is that their effects will be masked by those associated with the other impacts of the changing environment. An increase in the frequency of intense storms could potentially have a significant effect. Mean windspeed is not necessarily the most important element of windspeed - the distribution of windspeed, and also wind direction during storm events are equally important when making predictions of the effect of a changing wind climate on woodland and forestry.
