Land utilization and urban land use planning

Structural settlement measures always have an influence on the local climate and, as a rule, will influence the natural (prevailing) climatic conditions. Not only current global climate discussions have increasingly brought this issue to the fore, particularly in local context. Citizens are also questioning impact on their immediate surroundings in this respect. The importance of this issue is revealed in that settlement related climatic effects are directly reflected in planning law. More information in german...

 

 

Thermal wind systems

Thermal wind systems develop in autochtonal weather conditions, i.e. with little cloud coverage and weak winds. In orographically structured terrain, down-slope or mountain breezes occur in the evening and at night, and predominantly up-slope or valley breezes occur during the day. A land/onshore circulation develops at the coast and at larger lakes. Such weather conditions can lead to local urban wind field near larger towns. These wind systems are of significance to urban planning. More information in german...

 

 

Cold air drainage flows

Locally formed cold air is the result of air being cooled down due to a negative surface energy buget during night hours. Generally high air-pressure and low prevailing winds are favourable conditions. The cold air follows local terrain slopes (drainage flows). Characteristically, the wind direction changes within short distances according to the orientation of the local slope. Very often, several cold air flows merge into larger scale flow systems, which are able to overflow lower ridges and reach out several kilometres even into flat terrain.

Hour-by-hour time series measurements (AKTerm)

Wind measurements are often of great significance for the assessment of meteorological conditions. The frequency of their occurrence at a location is also important. Such measurements can play a key role in the preservation of evidence, e.g. when investigating the relevance of a neighbourhood complaint. In addition, wind measurements can be accordingly planned and executed so that important meteorological input data. More information in german...

 

 

Dispersion category statistics (AKS)

Wind measurements are frequently of great significance for the assessment of meteorological conditions at a location. Furthermore, they can play a key role in the preservation of evidence, e.g. when investigating the relevance of a neighbourhood complaint. In addition to the hourly values, for example, the statistical distribution of the measured parameters is frequently of relevance. If information on turbulence is integrated in addition to wind direction and wind velocity, dispersion category statistics (AKS) can be prepared, e.g. for use in a dispersion analysis.
