Comparison of precipitation data between the Arctic and East Africa — •Naoki Itoh1 and Jürgen Kurths2 — 1Interdisciplinary Center for Dynamics of Complex Systems, Potsdam, Germany — 2Potsdam-Institut für Klimafolgenforschung e.V., Potsdam, Germany
The comparison of climate change between the Arctic land (71.25oN and 179.75oE) and the equatorial area (Kenya) is performed by singular spectrum analysis (SSA) which is applied to the monthly precipitation of 1900’s. This method can be used to decompose the time series into some useful components. From the climate data such as precipitation trends, periodic-(annual cycle), quasi periodic and noise components can be extracted as information in the time series. Their results give us reasonable interpretation in the climate sense.
