Abstract:
Relationships between key parameters in global ecological models with different degree of detailedness have been studied. It is shown that consideration of positive feedback between “global average temperature” and “increasing of water vapor” leads not only to growth of constant of the total equable climate sensitivity, but also to rise of constant of heat inertia. Constant of the effective climate sensitivity changes a little that makes difficulties for identification of the model parameters on the basis of instrumental observations. Regarding this, it is interesting to compare a quantitative value of the constant of the total equable climate sensitivity of the Earth obtained from theoretical evaluations with corresponding evaluations made from paleoclimatic data which is obtained from chemical and isotopic analysis of the two Antarctic ice cores: “Vostok” and “Dome C”. It is shown a good conformity between theoretical evaluations and paleoclimatic data analysis.
Key words:
climate sensitivity, overrating parameters, positive feedback, greenhouse effect, radiation-adiabatic model, paleoclimate, Antarctic ice cores: “Vostok” and “Dome C”.
