摘要:An urban climate and air pollution study in the small
town of Biel (Switzerland; population: 85000 including suburbs) aims not only at the analysis of a very
dense distribution of emissions, dispersion climate
and depositions, but also attempts to correlate these
factors with selected effects on man. These effects
include the impacts on children's respiratory organs
and the growth of plants (liehen). The findings of this
study will have direct application in land use planning
and related political decisions for new highway
Systems, selection of new housing developments and
industrial districts, as well as future fuel supply
options.<br>
Initial results show that future activities should
concentrate on case studies during anticyclonic
wintertime weather types with north-northeasterly
synoptic flow. These weather types are associated with
cold air advection, weak winds, strong temperature
inversions and consequently, high air pollution rates
in the Biel area. A first draft of a very dense analysis of
the air pollution potential for a similar weather type
has been worked out (figure 5). This analysis will be
used for the design of additional mobile measurements and modeling studies.
