A short description of a new thematic mapping system for complex climatic conditions on a local and regional scale is given. The mapping system is mainly based on the contributing processes in the local earth/air system and the wind systems associated with the actual terrain conditions. The main climatic conditions are indicated by a number of symbols — all indicating the character of several atmospheric factors. The symbols have relative values and cover certain ranges of variations, but none indicates numerical values.As a basis for the mapping of climatic conditions, topographic maps of 1:50 000, 1: 20 000 or 1: 10 000 are used, depending on terrain conditions and detail requirements.The system has been tested both in teaching planners and in practice, and the Norwegian governmental planning authorities are attempting to include it in the official use of thematic maps.
