We expect a numerical simulation to improve upon our first guess; typically some sort of climatology. If a model is not better than this initial estimate of the ocean state, the model provides no new information and serves no purpose. Very often in coastal regions we are interested in predicting events—episodes when the ocean state differs greatly from the climatology. The ability of a model to...

Highlights of the 6th International GEWEX Science Conference and Joint GEWEX/iLEAPS Sessions Melbourne, Australia, 24–28 August 2009 See page 11 Global Precipitation Climatology Project (GPCP) Version 2.1 precipitation climatology, 1979–2008, in mm/day. This combination of satellite estimates based on infrared, microwave, and sounding data, together with gauge analyses, yields a global average ...

The structure of the wind-driven circulation in the subtropical South Pacific is studied using simple diagnostic and analytical models. The diagnostic calculation is based on the Levitus climatology. The analytical model is forced by observed winter mixed layer density and depth calculated from the Levitus climatology and by the surface wind stress data from the Hellerman and Rosenstein climato...

Climatology is a comparatively new science which has been progressing rapidly in recent decades. Essentially, conceptualization of its subject—“climate”—is not yet complete. The concept of climate has been transforming along with the development of climatology. At the beginning of the new century climatology is in front of necessity to extend the sense of the concept of climate as compared to t...

The wind/wave climatology for the Arctic Seas will be developed based on altimeter observations. It will have a major scientific and applied significance as presently there is no reference climatology for this region of the ocean available. The new versions of wave models for the Beaufort and Chukchi Seas will include new physics that is already under development, and the novel physics presentl...

Solar surface irradiance is an important variable in many different fields, e.g., climate monitoring and solar energy. Remote sensing data are nowadays well established and the only observational data source in many regions of the world. Aerosols significantly affect the clear sky radiation and hence also the all sky radiation. In order to achieve the optimal accuracy for surface radiation, inf...

The inter-comparison of different soil moisture (SM) products over the Tibetan Plateau (TP) reveals the inconsistency among different SM products, when compared to in situ measurement. It highlights the need to constrain the model simulated SM with the in situ measured data climatology. In this study, the in situ soil moisture networks, combined with the classification of climate zones over the...

In this experience report we consider some issues in the development of a data warehouse for meteorological and climatology data at MeteoSwiss. The paper describes the meteorological and climatology data process, the data warehouse architecture developed to support this process while integrating legacy systems and some of the modelling issues encountered.
