Urbanization: Its Detection and Effect in the United States Climate Record

摘要: Abstract Several equations were developed that related the effect of urban growth, measured by increasing population, to mean seasonal and annual temperature: diurnal maximum, minimum, average, range. These derived from a network 1219 stations across United States, which analyzed for years 1901–84. The results indicate effects on temperature are detectable even small towns with populations under 10 000. Stations near 000 shown average 0.1°C warmer than nearby located in rural areas less 2000. Urbanization decreases daily maxima all seasons except winter range seasons. It increases minima means that, temperature, urbanization during twentieth century accounts warm bias about 0.06°C U.S. Historical Climatology Network (HCN). ...
