The frequency of forest fires during the past 600 yr was studied on 281 sample plots within boreal forest ecosystems in a river valley in northern Sweden. Fire scars in living and dead trees were used for dating past fires. Before fire suppression started in the 19th century the…

Plume trajectory measurements were made at a power station on the South African Highveld under mainly near-neutral stability conditions. The maximum distance of observation ranged from 1050 to 6750 m. The fit of the models of Briggs (1969, 1970) and of Moore (1973, 1974) to the…
