Simulation of Climate and Weather Extreme Indices with the INM-CM5 Climate Model

详细

The simulation of extreme weather indices with the INM-CM5 and INMCM4 climate models for modern climate which were developed in the Institute of Numerical Mathematics of Russian Academy of Sciences is considered. It is shown that the INM-CM5 model improved the simulation of almost all indices concerning temperature (especially to its minimum values) and precipitation (mean total precipitation, mean precipitation intensity) extremes and concerning consecutive dry days and consecutive wet days. At the same time, the simulation of indices connected with extreme heavy precipitation became worse. It was found that this shortcoming can be minimized by introducing the vertical mixing of horizontal wind for the large-scale condensation and deep convection.
