ABSTRACT: The RegCM model system was originally developed in the late 1980s, and it was the first limited area model applied to climate studies. Over the last 25 yr, the system has been improved through successive model versions (RegCM1 to RegCM4), incorporating increasingly comprehensive physics packages and interactively coupled components of the climate system (chemistry/aerosol, ocean, lake, biosphere). The present Climate Special includes studies using RegCM3 and the latest version RegCM4. The papers illustrate that RegCM is a flexible and versatile system which can be used for different regions of the World and for a wide range of applications. Plans for the development of the next non-hydrostatic version RegCM5 are also described.
