Abstract

The time series of the global mean temperature in the last century shows different periods of steeply increasing temperature and periods where the temperature stagnates. A possible reason for these differences might be internal variability of the climate system. Here I apply singular spectrum analysis (SSA) to surface climate data in order to find long-periodic oscillations. Therefore different regions in the northern and tropical Atlantic and Pacific are analysed, where variations on interannual to multidecadal timescales are already known (except for the tropical Atlantic). The Atlantic Multidecadal Oscillation (AMO), the Pacific Decadal Oscillation (PDO) and the El Nino / Southern Oscillation (ENSO) can be proofed by using the SSA. Comparing these oscillations with the time series of the global mean temperature, evidence that these oscillations can cause the different phases of the temperature profile can be found. Thus, this might be the reason for the current global warming hiatus.
