About
On an everyday basis, many people use weather forecasts to determine what to wear on a given day. Since outdoor activities are severely curtailed by heavy rain, snow and wind chill, forecasts can be used to plan activities around these events, and to plan ahead and survive them.Weather forecasting is a part of the economy. For example in 2009, the US spent approximately $5.8 billion on it, producing benefits estimated at six times as much.
