Abstract
The impact of the major meteorological processes on the concentration of formaldehyde in the city of Tomsk is studied. It is shown that the highest concentrations are mostly established at low atmospheric pressures in a combination with high air temperatures. The relative humidity effect is insignificant. The weak precipitation reduces the pollution concentration. The amount of background formaldehyde pollution caused by the permanent man-made and natural sources is determined. The grouping of various types of synoptic processes in five compact classes being signs of possible formation of high concentration of formaldehyde is proposed.
