The Second Canadian Conference on Micrometeorology was held in Montreal, Canada, from May 10 to 12, 1971. Fifty-four scientific papers were presented to the over 140 scientists in attendance. The areas of research discussed generally followed the program of the First Canadian Conference on Micrometeorology (Toronto, 1965).
Invited papers by H. H. Lettau, R. W. Stewart and H. E. Landsberg were highlights of the conference. The lively discussions of these and other papers contributed importantly to the success of the meeting. In this regard we must mention the comments of C. Tanner and W. C. Swinbank who acted as invited discussants for two of the sessions.
A group of six papers was included in the first session on Agriculture and Forestry. The first two papers, presented by N. Barthakur and P. Schuepp, discussed the applicability of wind or fluid tunnel measurements to the heat and mass transfer from plant leaves. The following paper by L. H. Allen concerned the measurement of the flux divergence of water vapour and CO 2 in a corn field. This interesting case study focussed attention on the practical problems of conducting micrometeorological research on a typical site, that is, not an infinite plane. T. A. Black and E. Mukammal also stressed this problem as it applied to their forest energy-balance studies. The session was closed with a paper by T. Sinclair on a Bowen-ratio method for calculating energy flux densities.
Climatonomy was the subject of the invited paper by H. H. Lettau. Climatonomy is described as a theoretical modelling technique for local climates which is analogous to the approach of systems engineers to design problems. The technique provides for prediction of the climate change resulting from modification of any single parameter in the system. Several applications of the concept were discussed as well as some fascinating specific examples.
The five papers on Air Pollution (K. Yoshida, G. Csanady, R. Rowe, P. Slawson and 0. Johnson) were concerned with the dispersion of pollutants. Areas of interest included atmospheric dispersion of herbicide sprays, the effects of wind shear on diffusion, turbulent jets, and moisture effects on plumes.
The session on Heat and Water Budgets of Small Lakes was introduced by P. J. Barry. From the discussion that followed the four papers, it was clear that although this area of study is very pertinent to Canada, the experimental and interpretative difficulties of such studies are very formidable. Three of the papers (H. Ferguson, R. Polavarapu, and W. Selander) were concerned with the Perch Lake study. In the Boundary-Layer Meteorology 2 (1971) 255-257.
