Abstract: Seasonal and interannual variations in Sierra Nevada winter storms are discussed with reference to precipitation augmentation. Seasonal variations occur with respect to freezing level, storm type, vertical cloud distribution, ...

Abstract: Ten-year climatologies from the Sierra Cooperative Pilot Project (SCPP) show diurnal variations of clouds, precipitation, supercooled liquid water, stability and temperature. Diurnal variations were generally more pronounced ...

Abstract: This note discusses a Geostationary Operational Environmental Satellite product that can reveal the low clouds associated with tropical cyclones at night. It is based on a pixel-by-pixel difference of the longwave (10.8 ...

Abstract: Advanced Very High Resolution Radiometer channels 4 (11 ?m) and 5 (12 ?m) are used together to produce images which greatly enhance contrails. Four steps are required: 1) select coregistered digital data sets from the two ...

Abstract: Visible and infrared (IR) images from the National Oceanic and Atmospheric Administration's (NOAA's) Advanced Very High Resolution Radiometer are composited to improve the depiction of airborne dust over coastlines. On IR ...

Abstract: The 3.7-?m channel on-board the National Oceanic and Atmospheric Administration's (NOAA) Advanced Very High Resolution Radiometer (AVHRR) provides the unique capability to detect small, but hot, surface features. We present ...

Abstract: Near-surface wind speed analyses from the Special Microwave/Imager (SSM/I) are compared with those from an operational numerical forecast system. Substantial agreement exists, especially over open ocean. Nevertheless, the ...

Abstract: The authors develop and discuss satellite image enhancements of sea ice boundaries to the north and west of Alaska. Using data from the NOAA Advanced Very High Resolution Radiometer (AVHRR), the authors illustrate how a ...

Abstract: Overprediction of the spatial extent of aircraft icing is a major problem in forecaster products based on numerical model output. Dependence on relative humidity fields, which are inherently broad and smooth, is the cause ...
