Northern hemisphere extratropical ocean-atmosphere interactions from a coupled climate network perspective

In recent years extensive studies on the Earth’s climate system have been carried out by means of advanced complex network statistics. The great majority of recent studies, however, have been focusing on investigating interaction structures within single climatological fields directly on or parallel to the Earth’s surface. It is well-known, however, that many processes observed in the Earth system can only be explained by analyzing interactions between different climatological variables, especially those taken from the two major subsystems atmosphere and ocean.
