AB: PRECIS, Providing REgional Climates for Impacts Studies, is a regional climate modelling system developed by the Hadley Centre. The PRECIS system is based on the latest RCM version developed by the Centre, it has been designed to be user-friendly and easily implemented on any fast PC with Linux system. Due to the versatility and capability of the system in providing high-resolution climate simulations over any area of the globe, users of PRECIS are gaining confidence quickly. More than a pedagogical and portable tool for teaching regional climate modelling, PRECIS have been tested over North America domains. The simulations of PRECIS were generated over North America with different domain sizes by applying lateral boundary conditions (dynamical atmospheric information) from ECMWF ReAnalysis data provided from 12/1978 to 05/1982. Monthly and seasonal means fields have been used for the different realizations. The author presents results of these experiments and provides comparisons between PRECIS, the driving GCM (ERA) and observational datasets (e.g. CRU).
