RISThe Sensitivity of Mountain Snowpack Accumulation to Climate Warming
Publisher: American Meteorological Society
Abstract: Controls on the sensitivity of mountain snowpack accumulation to climate warming (?S) are investigated. This is accomplished using two idealized, physically based models of mountain snowfall to simulate snowpack accumulation ...
The Simulated Response of Diurnal Mountain Winds to Regionally Enhanced Warming Caused by the Snow Albedo Feedback
Publisher: American Meteorological Society
Abstract: AbstractThe snow albedo feedback (SAF) is an important climate feature of mountain regions with transient snow cover. In these regions, where patterns of snow cover are largely determined by the underlying terrain, the SAF ...
Mesoscale Variations of the Atmospheric Snow Line over the Northern Sierra Nevada: Multiyear Statistics, Case Study, and Mechanisms
Publisher: American Meteorological Society
Abstract: bservations from several mountain ranges reveal that the height of the transition from snowfall to rainfall, the snow line, can intersect the terrain at an elevation hundreds of meters below its elevation in the free air ...
Characterization of the Simulated Regional Snow Albedo Feedback Using a Regional Climate Model over Complex Terrain
Publisher: American Meteorological Society
Abstract: idlatitude mountain regions are particularly sensitive to climate change because of an active snow albedo feedback (SAF). Here, the SAF is characterized and quantified over the complex terrain of the Colorado Headwaters ...
The Simulated Impact of the Snow Albedo Feedback on the Large-Scale Mountain–Plain Circulation East of the Colorado Rocky Mountains
Publisher: American Meteorological Society
Abstract: AbstractThe Front Range mountain?plain circulation (FRMC) is a large-scale diurnally driven wind system that occurs east of the Colorado Rocky Mountains in the United States and affects the weather both in the Rocky Mountains ...
The Dynamics of Ascent-Forced Orographic Convection in the Tropics: Results from Dominica
Publisher: American Meteorological Society
Abstract: he mountainous Caribbean island of Dominica was chosen as a natural laboratory for studying orographic convection in the tropics. Here, the authors focus on a prototypical case study, taken from the Dominica Experiment ...
Mesoscale Controls on the Mountainside Snow Line
Publisher: American Meteorological Society
Abstract: bservations show that on a mountainside the boundary between snow and rain, the snow line, is often located at an elevation hundreds of meters below its elevation in the free air upwind. The processes responsible for this ...
Wind Speed Control of Tropical Orographic Convection
Publisher: American Meteorological Society
Abstract: his study compares observations from the Dominica Experiment (DOMEX) field campaign with 3D and 2D Weather Research and Forecasting Model (WRF) simulations to understand how ambient upstream wind speed controls the transition ...
Downstream Evolution and Coastal-to-Inland Transition of Landfalling Lake-Effect Systems

The Character and Causes of Elevation-Dependent Warming in High-Resolution Simulations of Rocky Mountain Climate Change
Publisher: American Meteorological Society
Abstract: AbstractThe character and causes of elevation-dependent warming (EDW) of surface temperatures are examined in a suite of high-resolution ( km) regional climate model (RCM) simulations of climate change over the Rocky ...
