This study analyzes the occurrence of days with dew in the city of São Paulo and correlates it with air temperatures and the dew point, as well as with the relative and absolute humidity of the air, based on daily data for the period from 1958 to 2007, obtained at the Meteorological Station of the University of São Paulo Institute of Astronomy, Geophysics, and Atmospheric Sciences (IAG-USP), Parque Estadual Fontes do Ipiranga (PEFI). Statistical analysis of linear regression and analysis of variance (ANOVA) show an increase in the frequency of days with dew, especially in autumn, as well as an increase in temperature and absolute humidity and a decrease in relative humidity during these 50 years.Downloads
