I can honestly say, i have heard it all.
Interesting that you say that.....here is a link ....

"The construction of a building inevitably changes the microclimate in its vicinity. In particular near high-rise buildings, high wind velocities are often introduced at pedestrian level that can be experienced as uncomfortable or even dangerous. Therefore, the design of a building should not only focus on the building envelope and on providing good indoor environment, but should also include the effect of the design on the outdoor environment. The outdoor environment of a building, in particular related to wind, has received relatively little attention in the Building Physics community."

"The presence of a nearby structure influences the pressures on a high-rise building due
to interference. The present paper describes the results of an experimental study
carried out on rigid models of buildings in a boundary layer wind tunnel in order to study
the interference effect. A model of a low-rise building is placed on the upstream side of
a high-rise building model and the wind environment between the two is measured.
Spacing between the two models is varied in order to study the influence of spacing on
the wind environment. It is observed that the wind environment between the two
buildings is changed and thus wind pressures on high-rise buildings are adversely
affected. This influence is quite distinct for the spacing values up to 5 times the height of
the low-rise building model."
