The model

PRECIS contains two regional climate models; HadRM3P and the HadRM3Q0 regional model used in the QUMP project. HadRM3P is a regional model based on the

General Circulation Model A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean. It uses the Navier–Stokes equations on a rotating sphere with thermodynamic ter ...

PRECIS workshops

PRECIS is made available at workshops run regularly by Met Office Hadley Centre staff, generally in the region where it is to be used. Workshops are provided to give scientific and technical training necessary to use PRECIS and address the many issues involved in its application. There are generally three international and one UK based PRECIS workshops held each year. PRECIS workshops have provided training covering over 100 countries and over 300 participants. The workshops have been successful in encouraging collaboration between PRECIS users in groups of countries.
