Interhemispherical delay of the current warming gives a first evidence of the greenhouse gases signal
- Hydrometeorological Research Centre of Russia, Moscow (Russian Federation)
The most accurate TRENDS`93 time series of the hemispherical surface air temperatures and the corresponding greenhouse gases concentrations were processed by means of the technique of wavelet transform. The technique easily admits splitting the time series of interest to statistically stationary oscillations and a trend. Such temperature oscillations of interannual-interdecadal scales were extracted which include differences between both hemispherical temperature series. In particular, these oscillations depict an increasing of the temperature during 1900--1930s in both hemispheres. A relative cooling in the Northern Hemisphere (a temperature stabilization in the Southern one) during 1940--1970s, and a strong warming in both hemispheres are depicted in the latest decades. One can assume that the contributions of these oscillations to global warming will be negative during the next decade.
