RELATIVE HUMIDITY TRENDS
|
Relative humidity strongly affects atmospheric visibility, directly influencing cloud height as well as the formation of smog and fog. Nonetheless, compared to the number of studies of temperature and precipitation records, relatively little work has been done examining archival data of relative humidity searching for evidence of climate change.
In the first study of relative humidity in Canada analyzing data taken on an hourly basis over the period 1953-2003, we have found no discerni...
