Momentum Transport by Gravity Waves
Publisher: American Meteorological Society
Abstract: The momentum flux by orographic gravity waves and the turbulent heat flux in wave-breaking regions are estimated from aircraft data from ALPEX. The fluxes on 6 March 1982 are controlled by low-level directional shear of ...
A Multiyear Regional Climate Hindcast for the Western United States Using the Mesoscale Atmospheric Simulation Model
Publisher: American Meteorological Society
Abstract: In preparation for studying the effects of increased CO2 on the hydrologic cycle in the western United States, an 8-yr hindcast was performed using a regional climate model (RCM) driven by the large-scale forcing from the ...
Numerical Prediction of Precipitation and River Flow over the Russian River Watershed during the January 1995 California Storms
Publisher: American Meteorological Society
Abstract: Precipitation and river flow during a January 1995 flood event over the Russian River watershed in the northern Coastal Range of California were simulated using the University of California Lawrence Livermore National ...
The Impact of the Sierra Nevada on Low-Level Winds and Water Vapor Transport
Publisher: American Meteorological Society
Abstract: To understand the influence of the Sierra Nevada on the water cycle in California the authors have analyzed low-level winds and water vapor fluxes upstream of the mountain range in regional climate model simulations. In a ...
The Impact of Direct Aerosol Radiative Forcing on Surface Insolation and Spring Snowmelt in the Southern Sierra Nevada
Publisher: American Meteorological Society
Abstract: To understand the regional impact of the atmospheric aerosols on the surface energy and water cycle in the southern Sierra Nevada characterized by extreme variations in terrain elevation, the authors examine the aerosol ...
Uncertainty Propagation of Regional Climate Model Precipitation Forecasts to Hydrologic Impact Assessment
Publisher: American Meteorological Society
Abstract: A Monte Carlo framework is adopted for propagating uncertainty in dynamically downscaled seasonal forecasts of area-averaged daily precipitation to associated streamflow response calculations. Daily precipitation is modeled ...
Influence of GPS Precipitable Water Vapor Retrievals on Quantitative Precipitation Forecasting in Southern California
Publisher: American Meteorological Society
Abstract: The effects of precipitable water vapor (PWV) retrievals from the Southern California Integrated GPS Network (SCIGN) on quantitative precipitation forecast (QPF) skill are examined over two flood-prone regions of Southern ...
Geostatistical Mapping of Precipitation from Rain Gauge Data Using Atmospheric and Terrain Characteristics
Publisher: American Meteorological Society
Abstract: A geostatistical framework for integrating lower-atmosphere state variables and terrain characteristics into the spatial interpolation of rainfall is presented. Lower-atmosphere state variables considered are specific ...
On the Relationship between Spring NAO and Snowmelt in the Upper Southwestern US
Publisher: American Meteorological Society
Abstract: his study examines the relationship between the North Atlantic Oscillation (NAO) and snowmelt in spring in the upper southwestern states of the US (UP_SW) including California, Nevada, Utah, and Colorado, using SNOTEL ...
The Effects of the Gulf of California SSTs on Warm-Season Rainfall in the Southwestern United States and Northwestern Mexico: A Regional Model Study
Publisher: American Meteorological Society
Abstract: The impacts of the sea surface temperatures (SSTs) in the northern Gulf of California (GC) on warm-season rainfall in the Arizona?New Mexico (AZNM) and the northwestern Mexico (NWM) regions associated with the North American ...
