Estimation of frequency response of the global temperature to change in radiative forcing

Authors: Bogdanov M. B., Chervyakov M. Y.

The Earth’s climate system (ECS) is considered as a linear system whose input is a change in the solar constant ΔI( t) and the output is an anomaly of the globally averaged surface temperature ΔT( t). The system input can be affected by other factors, and at the output their own temperature fluctuations and a random noise manifest themselves. All these factors are assumed to be independent of ΔI( t). The spectral analysis of monthly mean values of ΔI( t) and ΔT( t) shows the existence of statistically significant coherence.

Estimation of Frequency Response of Earth’s Climate System to External Radiative Forcing

We consider the Earth’s climate system (ECS) as a linear system whose output is the global mean temperature anomaly DТ(t). The input the system, along with changes in the solar constant DI(t), can be affected by other factors, and at the output manifest themselves own temperature fluctuations and a random noise. The spectral analysis of the data shows the existence of statistically significant coherence between DI(t) and DТ(t).
