3. The regional climate and air situation
Wind conditions



Fig. 3.2: Average frequency (in %) of the wind direction at Stuttgart airport (1961-1980)
The most frequent and also strongest winds in the region of northern Württemberg as a long-term average come from West to Southwest (prevailing wind direction). This can be seen in the wind rose (not restricted to this location) at the airport in Stuttgart-Echterdingen, which is represented in figure 3.2 (established on the basis of the data from Flugwetterwarte Stuttgart (a meteorological service indicating flying weather) from the German Meteorological Service).

The 12-parts wind rose at Stuttgart airport is dominated by a wind direction sector between Southwest and West (230 to 250 degrees) as the prevailing wind direction with a frequency of 18 %, besides 15 % lulls.

Southeast and East are rare wind directions with absolutely low wind speeds in this region and they represent the term "inversion weather condition". (The average wind speed of southeasterlies is only 1.6 m/s, compared to an average of 3.6 m/s for southwesterlies.)

The average wind speed in our climatic region is only 2.5 m/s. This means that Greater Stuttgart is a region with relatively low wind speeds. Hamburg, for example, has an average wind speed of about 5 m/s. Flat inland regions usually have average wind speeds of about 4 m/s.

The above-mentioned very low wind speeds of up to 1.5 m/s (including lulls) have an average annual frequency of about 44 %. The frequency of low wind speeds increases slightly during the winter half year and reaches 46 %.
