Conceptual Model Approach

The physical-meteorological evaluation of a combination of such different data as descriptions of image structures, irregular distributed point measurements from synoptic observations and numerical parameter fields on a defined grid is not a simple task. There is, however, one tool already widely used in synoptic research and operations - the Conceptual Model Approach.

Definition of conceptual models

A definition of conceptual models as well as examples showing the usefulness have been derived among European countries in the frame of the COST 78 action (Development of forecasting techniques):

A conceptual model describes essential features of a meteorological phenomenon and identifies the principal processes taking place.

A complete conceptual model provides a:

Additional Explanatory Statements

There are some additional, explanatory statements to this definition about satellite images and conceptual models:

Many instances of the same weather system have to be investigated to develop a specific CM. In SatManu about 100 cases have been diagnosed for frequent weather systems, while for rarer cases the number is about 30. Those features and configurations that are common to all cases and can be explained by the relevant physical-meteorological processes are described in a single SatManu chapter on CM structure and presentation (link to chapter "Structure and Presentation of CMs in SatManu").

Conceptual models provide the meteorologist with:
