Climate and climate change in western canada as simulated by the Canadian regional climate model

摘要: Abstract A þrst climate simulation performed with the novel Canadian Regional Climate Model (CRCM) is presented. The CRCM based on fully elastic non‐hydrostatic þeld equations, which are solved an efþcient semi‐implicit semi‐Lagrangian (SISL) marching algorithm, and parametrization package of subgrid‐scale physical effects second‐generation Global (GCMII). Two 5‐year integrations nested GCMII simulated data as lateral boundary conditions made for corresponding to current doubled CO2 scenarios. For these simulations used a grid size 45 km polar‐stereographic projection, 20 scaled‐height levels time step 15 min; nesting has spectral truncation T32, 10 hybrid‐pressure min. These serve document: (1) suitability SISL numerical scheme regional modelling, (2) use physics at much higher resolution than in nesti...
