cont;iiiul i c s u l t s of inc;i~urcnieiits in wind tunnels describing some aspects
of the structure of turbulence in the boundary layer. In addition to the
statistical characteristics, enpcrimental wind-tunnel studies of flow in
turbulent shear layers involve the observation of well-ordered flow structures including bursts and turbulent intermittencies. Studies of such
phenomena and of their similarity in the laboratory and in nature appear
to be of particular importance.
Onc 01 thc sessions was devoted to the studies of turbulent diffusion in
the sea and in stratified waters. A report was also presented on some
preliminary studies of air-sea interactions in a large wind-water tunnel.
Several papers were concerned with atmospheric pollution and with
rnitherncltical modeling of urban pollution. it should be noted that the
first use of mathematical modeling of urban pollution reported in 1957
and based on the statistical theory of turbulence was only mentioned in
the first IIJTAM--1CJGG Symposium held in Oxford; however. during the
second IIJTAM. IUGG Symposium there were several papers presented on
this sub-iect. The use of mathematical modeling of pollution has now become
more practical. but scveral fundamental questions about the methodology
of simulation modeling require further studies. Of particular importance is
the possible application of the statistical theory of turbulence to such
studies and the availability ofappropriate data on the structure of turbulence.
Discussions of the laboratory simulation of atmospheric turbulence and
the comparison between turbuient diffusion in the wind tunnel and in
the atmosphere appeared in several papers. Such studies appear to be of
special interest and could involve the use of mathematical modeling of the
laboratory experiments whose main purpose would be to improve the
methodology of simulation modeling. While such studies have not been
reported during the Symposium, they appear to be quite promising.

devoted to regional and global pollution studies. Both experimental and
tlicorctical results of such studics were reported.
