KLIWAS North Sea Climatology

In the frame of the research program KLIWAS (Klimawandel und Wasserstraßen) of the Bundesministerium für Verkehr, Bau und Stadtentwicklung new hydrographic and meteorological climatologies of the North Sea and surrounding regions (47 to 65 °N, 15 °W to 15 °E) were established in a cooperation of the Exzellenzcluster CliSAP of the University of Hamburg, the Bundesamt für Seeschifffahrt und Hydrographie, Hamburg, and the Deutscher Wetterdienst, Hamburg.

Observational data from several sources were collected and processed for the calculation of the quality-controled climatologies. The climatologies consist of gridded, yearly and monthly mean hydrographic and surface meteorological data, respectively. It is planned to expand the climatologies including additional and especially actual data in future versions.

 

Hydrographic Climatology

Fig.: Mean temperature (°C) and salinity (psu) at the sea surface using all yearly means. The white lines show the bottom contours of 100, 500, and 2000 m depth.

The first version of the hydrographic climatology contains temperature and salinity data at 179 depth levels of the ocean on a 0.25° x 0.5° latitude-longitude grid for the period 1890 to 2011.

Meteorological Climatology

Fig.: Monthly mean air temperature in °C, July 1971-2000, data: DWD
air temperature / air pressure climatology Jul 1971-2000
Fig.: Monthly mean sea level pressure in hPa, July 1971-2000, data: DWD

The first version of the meteorological climatology contains air temperature, air pressure and dew-point temperature at the sea surface on a 1° x 1° latitude-longitude grid for the period 1950 to 2010.
