The INMCM5.0 numerical model of the Earth’s climate system is presented, which is an evolution from the previous version, INMCM4.0. A higher vertical resolution for the stratosphere is applied in the atmospheric block. Also, we raised the upper boundary of the calculating area, added the aerosol block, modified parameterization of clouds and condensation, and increased the horizontal resolution in the ocean block. The program implementation of the model was also updated. We consider the simulation of the current climate using the new version of the model. Attention is focused on reducing systematic errors as compared to the previous version, reproducing phenomena that could not be simulated correctly in the previous version, and modeling the problems that remain unresolved. 相似文献

Analysis of Simulation of Stratosphere-troposphere Dynamical Coupling with the INM-CM5 Climate Model
The simulation of stratosphere-troposphere dynamic coupling is considered in five 50-year realizations of ensemble calculations with the 5th version of the INM-CM5 climate model developed in the Marchuk Institute of Numerical Mathematics of Russian Academy of Sciences. The model also includes the ocean model and the improved vertical resolution in the upper stratosphere and lower mesosphere. 相似文献

The aerosol module is included into the INM RAS climate model. The module computes the evolution of main aerosols: sea salt, mineral dust, sulfate aerosol, and black and organic carbon. Aerosol surface fluxes, advection, gravitational sedimentation, surface absorption, and scavenging by precipitation are taken into account to compute aerosol concentration variations. Model aerosol distribution is used to compute radiation fluxes. The ten-year run of the climate model is performed. The climatology of model aerosol is considered. The aerosol mass, integral source values, optical thickness, and radiative forcing are presented. The results are compared with the data of other models and observations. 相似文献

An atmosphere-ocean general circulation model including the atmospheric chemistry and carbon cycle was used to perform numerical experiments to simulate the consequences of geoengineering. Out of the five emission scenarios considered here, the scenario where the injection of sulfur compounds occurs near the equator at an altitude between 22 and 24 km can be considered the most efficient in the sense of a maximum decrease in globally averaged surface temperature. We consider the equilibrium distribution of the sulfate aerosol and changes in temperature at the Earth’s surface and at different altitudes, in precipitation, in ozone concentration, and in primary plant productivity caused by geoengineering. 相似文献

The climate model of atmospheric and oceanic circulation is used to assess a potential of the geoengineering to stabilize the global temperature at the level of +2°C relative to the average for the 20th century. An anthropogenic forcing was set in accordance with the RCP8.5 scenario. The injection of H2S into the stratosphere transformed afterwards into the sulfate aerosol starts when the temperature reaches a threshold of +2°C. The intensity of the injection is chosen so that the estimated global temperature remains close to the threshold. It is demonstrated that the stabilization of temperature by geoengineering is possible within +(2 ± 0.11)°C during the 21st century. The stabilization of temperature by the end of the 21st century needs the yearly injection of 4.5 Mt S in the form of H2S. The specific efficiency of the method is about 0.09°C/Mt of aerosol. It was found that the stabilization of global temperature does not provide the stabilization of mean global precipitation. The maximum influence of aerosol is in the equatorial zone where its specific density in the atmosphere will reach 0.074 g/m2 by the end of the 21st century. Carried out is a comparison of regional features of temperature and precipitation fields with and without geoengineering. It is shown that the geoengineering will decrease significantly the regional anomalies in the most part of regions and will not increase them in the rest part. Estimated is an effect of the rapid growth in global temperature at the dramatic cessation of geoengineering impacts. Considered is a variant of the gradual decrease in geoengineering intensity, when the negative effects will be smoothed. 相似文献
