The PRECIS (Providing Regional Climates for Impacts Studies)
system has been developed at the Met Office to provide a tool
for predictions on a regional scale. PRECIS generates high-
resolution climate change information and can be applied in any
region of the world. Adaptation to change will require high-
quality climate change information, often with a lot of spatial
detail. This is where PRECIS is the ideal tool to use. Global
climate models predict large-scale changes in climate but are
not yet capable of providing the fine-scale information, about
areas such as mountains and inland water basins, or representing
high-resolution climate phenomena such as fronts and cyclones,
all of which are needed for some adaptation planning. One of the
first applications of the assessment of uncertainty using PRECIS
was in the Caribbean and Central America. PRECIS was run using
boundary conditions from different global climate models (GCMs).
Sea-surface temperatures are determined by the global models and
are very differe
