Multi‐<scp>GCM</scp> by multi‐<scp>RAM</scp> experiments for dynamical downscaling on summertime climate change in Hokkaido

Abstract

Abstract The experiments with three general circulation models ( GCMs ) by three regional atmospheric models ( RAMs ) for the dynamical downscaling ( DDS ) have been performed to evaluate the uncertainty in the global warming response during summertime in Hokkaido, Japan. The results of a 10‐year RAM integration nested into GCM under present or future climate conditions were synthesized after applying bias correction. For the target decades during which the global‐mean temperature increases by 2 K in each GCM , the DDS results indicate that surface air temperature and precipitation mostly depend on the GCM imposed as the lateral boundary condition.
