What does RCM mean in Military?

RCM

Three-dimensional regional atmospheric models, or Regional Climate Models(RCMs), are supposed to have a resolution on the order of 101 km and domains of up to a sub-continental size. Depending on the problem to be solved at their lateral boundaries, RCMs can be driven by (or, in other words, downscale) either GCM outputs or global atmospheric reanalyses. Finer scale RCMs can be nested into coarser scale RCMs. Though dependent on the quality of driving GCMs, RCMs allow for meaningful utilization in a broad spectrum of applications, particularly in climate change projections. Usually, an RCM will undergo a complex procedure of calibration and testing before it can be used for a certain region (i.e. it is “customized” to the region). If compared to other parts of the world, NEA (especially its northeastern part) is a region for which few RCMs exist (e.g. Shkolnik et al., 2001)The above description was taken from this source.
