Simulated diurnal range and variability of surface temperature in a global climate model for present and doubled CO2 climates

The large-scale geographical patterns of the standard deviation of temperature in a global climate model for climates at the present level of CO2 and doubled CO2 levels were simulated, using data from groups of individual stations to assess the simulation of the diurnal range of temperature.

Description
Summary:The large-scale geographical patterns of the standard deviation of temperature in a global climate model for climates at the present level of CO2 and doubled CO2 levels were simulated, using data from groups of individual stations to assess the simulation of the diurnal range of temperature. It was found that the simulated patterns of interannual standard deviation of surface temperature agree with observations, except over the tropical oceans and in high latitudes in winter, where the respective model values were found to be smaller or larger, respectively, than observed. The changes on doubling CO2 were found to be generally small and not statistically significant. However, there were reductions along the sea-ice margins in winter and increases in some regions of northern midlatitudes in summer. (I.S.)
