A time-varying regression model is considered, based on monthly precipitation data from gauge measurements. The model accounts for orographic effects, that is elevation and aspect of the terrain. The study area is NCDC climate division 2 in a mountainous area in northern New Mexico. We assess spatio-temporal variability and also trace the dependence of precipitation on El Niño/Southern Oscillat...
