The relationship between ground-level ozone concentrations, surface pressure gradients, and 850 mb temperatures in the Lower Fraser Valley of British Columbia / Bill Taylor.: En57-45/92-3E-PDF

"During the summer season, the Lower Fraser Valley of British Columbia occasionally experiences very high concentrations of ground-level ozone (photochemical smog). It has been determined that the duration and intensity of these episodes depends solely on meteorological conditions. This paper investigates the relationship between ozone concentrations and certain meteorological variables. A high correlation was found between ozone concentration and the temperature at 850 mb, with higher than average temperatures being observed when levels of ozone are elevated. These high temperatures at 850 mb are generally associated with subsidence inversions and low level stability. The results of the study indicate that ozone events are unlikely to occur below certain temperature thresholds which vary from one month to the next as the summer progresses. It was also found that virtually all occurrences of elevated levels of ozone happen when the west-to-east surface pressure gradient in the valley is negative"--Abstract.
