AbstractVarious weather factors are assessed in relation to corrosion of metals. Published data are discussed and new results presented to show that time-of-wetness is a very important factor and that reasonable values may be obtained from analysis of meteorological records. These are applicable for predicting long-range corrosion effects. For short-term corrosion, data must be collected for the particular exposure conditions. Results are presented to show the effect of orientation on time-of-wetness, and recommendations are made for increasing this type of study. A summary of data on pollution by SO[2] in major cities of Canada is presented and the distribution in Metro Toronto given. It indicates that pollution by SO[2] has been decreasing in many areas of the world. The effects on corrosion of chlorides, corrosion products, and temperature are also discussed.
