Stochastic versus Dynamical Downscaling of Ensemble Precipitation Forecasts
Publisher: American Meteorological Society
Abstract: The assessment of hydrometeorological risk in small basins requires the availability of skillful, high-resolution quantitative precipitation forecasts to predict the probability of occurrence of severe, localized precipitation ...
Multidecadal Variations in the Relationship between the NAO and Winter Precipitation in the Hindu Kush–Karakoram
Publisher: American Meteorological Society
Abstract: inter precipitation over the Hindu Kush?Karakoram (HKK) range in the western Himalayas is generated by westerly perturbations whose dynamics is affected by the North Atlantic Oscillation (NAO). Larger precipitation is ...
Sensitivity of Precipitation Statistics to Resolution, Microphysics, and Convective Parameterization: A Case Study with the High-Resolution WRF Climate Model over Europe
Publisher: American Meteorological Society
Abstract: e explore the impact of different resolutions, convective closures, and microphysical parameterizations on the representation of precipitation statistics (climatology, seasonal cycle, and intense events) in 20-yr-long ...
Snowpack Changes in the Hindu Kush–Karakoram–Himalaya from CMIP5 Global Climate Models
Publisher: American Meteorological Society
Abstract: he Hindu Kush, Karakoram, and Himalaya (HKKH) mountain ranges feed the most important Asian river systems, providing water to about 1.5 billion people. As a consequence, changes in snow dynamics in this area could severely ...
RainFARM: Rainfall Downscaling by a Filtered Autoregressive Model
Publisher: American Meteorological Society
Abstract: A method is introduced for stochastic rainfall downscaling that can be easily applied to the precipitation forecasts provided by meteorological models. Our approach, called the Rainfall Filtered Autoregressive Model ...
Precipitation Nowcasting by a Spectral-Based Nonlinear Stochastic Model
Publisher: American Meteorological Society
Abstract: A novel rainfall nowcasting method based on the combination of an empirical nonlinear transformation of measured precipitation fields and the stochastic evolution in spectral space of the transformed fields is introduced. ...
Verification of Quantitative Precipitation Forecasts via Stochastic Downscaling
Publisher: American Meteorological Society
Abstract: The use of dense networks of rain gauges to verify the skill of quantitative numerical precipitation forecasts requires bridging the scale gap between the finite resolution of the forecast fields and the point measurements ...
High-Resolution Simulations of the 2010 Pakistan Flood Event: Sensitivity to Parameterizations and Initialization Time
Publisher: American Meteorological Society
Abstract: stimating the risk of flood-generating precipitation events in high-mountain regions with complex orography is a difficult but crucial task. Quantitative precipitation forecasts (QPFs) at fine resolution are an essential ...
