List some of the factors that affect the accuracy of weather forecasts
Computer weather models have inherent flaws that limit the accuracy of weather forecasts. The models idealize the real atmosphere, meaning that each model makes certain assumptions about the atmosphere. These assumptions may be right for some weather situations and may be wrong for others. Therefore, the prog may one day be quite accurate and not so close on another.
Another forecasting problem arises because the majority of models are not global in their coverage, and errors are able to invade along the model's boundaries.
?
Models are also limited by the availability of data. Weather observations are sparse in some areas of the open ocean and in the polar regions. Satellites have helped to alleviate this problem.
?
Many computer models cannot adequately interpret many of the factors that influence surface weather, such as the interactions of water, ice, surface friction, and local terrain on weather systems.
