Does the Senate really need to confirm 1,200 executive branch jobs? By Brad Plumer By Brad Plumer July 16, 2013 Follow @bradplumer The Senate has been bickering all day over how to confirm President Obama's nominees for various executive-branch positions.
The climate calculated by the GCM is used as input at the edges of the RCM for factors such as temperature and wind. RCMs can then resolve the local impacts given small scale information about orography (land height) and land use, giving weather and climate information at resolutions as fine as 50 or 25km.
Using climate models in an experimental manner to improve our understanding of how the climate system works is a highly valuable research application. More often, however, climate models are used to predict the future state of the global climate system. Forecasts (or projections) can be made from a single model forecast, or from an ensemble of forecasts which are produced by slightly perturbing the initial conditions and/or other aspects of the model used.
