California Storms as Viewed by Sacramento Radar
نویسنده
چکیده
The WSR-57 radar a t Sacramento provides an opportunity to observe mountain effects on precipitation and on radar echo patterns. Radar patterns representing a wide range of weather situations are described and interpreted in light of concurrent gage precipitation measurements. The frequent underestimation by radar of rainfall on windward slopes is attributed to the small drop size and low formation level of the orographic precipitation. Overestimation on lee slopes is in part due to evaporation before the precipitation reaches the ground. Comparisons are made between gage precipitation depth and that indicated by the radar.

متن کاملRainfall Interception by Sacramento's Urban Forest
A one-dimensional mass and energy balance model was developed to simulate rainfall interception in Sacramento County, California. The model describes tree interception processes: gross precipitation, leaf drip, stem flow, and evaporation. Kriging was used to extend existing meteorological point data over the region. Regional land use/ land cover and tree canopy cover were parameterized with dat...
