Weather forecasting is one of the most challenging problems in environmental sciences. It has inspired and engaged many of the great scientists of our times, dating back to the turn of the 20th century. Many of the most popular numerical techniques for solving partial differential equations were first developed for the purpose of predicting weather.
The basic equations of weather are programmed into computer codes, which are often called numerical weather prediction models. These models are run daily to produce weather forecasts. Such models also form the basis for global climate models (GCMs), which are used to study and project climate change.
