Weather Forecasting Has Improved Greatly


Most weather forecasting models currently in use have resolutions ensuring accuracy to within 100 km which is a great improvement on the accuracy levels of approximately 300 km which were in use 15 years ago. Climate forecasts are based on computer models developed by using physics and advanced calculations and equations aimed at forecasting climate and weather patterns. Presently there is a great deal of international co-operation to co-ordinate weather forecasting globally at any given time by means of advanced computer models.

Dr Alan Thorpe, Director- General of the European Centre for Medium Weather Forecasting, recently indicated that with the development of these models it is possible to prepare more accurate weather forecasts. He said that it was anticipated that within a matter of years the levels of accuracy will be down to a few kilometres. This will be of great benefit to economic sectors such as agriculture, leisure and construction and it will also be a useful aid to those responsible for disaster management in times of floods and storms caused by extreme weather conditions as result of the increasing incidence of climate change.
