Physical Climate and Modelling
Earth’s climate system is an extremely complex, interactive system which consists of the atmosphere, land surface, snow, ice, oceans, and any other bodies of water and all the living things that call it home. When observing physical climate, this is often defined in terms of weather events, e.g. temperature and precipitation in various regional, on different time scales such as days, years, decades, etc.
Climate models are the tools researchers use to demonstrate the complex physical climate systems taking place around the world every day, and while there is a great deal of uncertainty, in recent years these models have improved significantly. Models are now able to include elements of the carbon and nitrogen cycles, interactive or dynamic vegetation ecosystems and an improved description of atmospheric circulation and processes. Predicting future climate change at both global and regional levels, researchers move closer every day to representing physical processes as close to reality as possible.
