Sensitivity Of Urban Water Consumption To Weather And Climate Variability At Multiple Temporal Scales: The Case Of Portland, Oregon, Heejun Chang, Sarah Praskievicz, Hossein Parandvash
International Journal of Geospatial and Environmental Research
The sensitivity of municipal water consumption to climate and weather variability is investigated for Portland’s water provider service area between 1960 and 2013. The relationship between detrended seasonal urban water use (the difference between total water use and base use) and weather and climate variables (precipitation, maximum temperature) is examined at daily, monthly, and seasonal scales using stepwise multiple regression and autoregressive integrated moving average (ARIMA) models. At a seasonal and a monthly timescales, interannual variation in maximum temperature is the most important predictor of seasonal water consumption per capita, explaining up to 48% of the variation in seasonal monthly …

Precipitation Patterns And Trends In The Metropolitan Area Of Milwaukee, Wisconsin, Anke P.M. Keuser
International Journal of Geospatial and Environmental Research
This study investigated changes in mean and extreme precipitation in the metropolitan area of Milwaukee, Wisconsin in an attempt to find the effects of urban areas on precipitation patterns. Precipitation data were obtained from a gridded (8-km spacing) historical climatic dataset for Wisconsin for 1950-2006. The Mann-Kendall test and the Sen’s slope test were applied to investigate temporal trends. Monthly wind directions were examined against monthly precipitation patterns. Main findings from the study include the following: (1) Annual precipitation significantly increased in the northern part of the study area during 1950-2006, whereas extreme precipitation showed virtually no trends; (2) The …
