When Will We Detect Changes in Short-Duration Precipitation Extremes?
Publisher: American Meteorological Society
Abstract: AbstractThe question of when the influence of climate change on U.K. rainfall extremes may be detected is important from a planning perspective, providing a time scale for necessary climate change adaptation measures. ...
Robustness of Future Changes in Local Precipitation Extremes
Publisher: American Meteorological Society
Abstract: Reliable projections of future changes in local precipitation extremes are essential for informing policy decisions regarding mitigation and adaptation to climate change. In this paper, the extent to which the natural ...
Using and Designing GCM–RCM Ensemble Regional Climate Projections
Publisher: American Meteorological Society
Abstract: Multimodel ensembles, whereby different global climate models (GCMs) and regional climate models (RCMs) are combined, have been widely used to explore uncertainties in regional climate projections. In this study, the extent ...
Realism of Rainfall in a Very High-Resolution Regional Climate Model
Publisher: American Meteorological Society
Abstract: he realistic representation of rainfall on the local scale in climate models remains a key challenge. Realism encompasses the full spatial and temporal structure of rainfall, and is a key indicator of model skill in ...
Large-Scale Predictors for Extreme Hourly Precipitation Events in Convection-Permitting Climate Simulations
Publisher: American Meteorological Society
Abstract: AbstractMidlatitude extreme precipitation events are caused by well-understood meteorological drivers, such as vertical instability and low pressure systems. In principle, dynamical weather and climate models behave in the ...
The Value of High-Resolution Met Office Regional Climate Models in the Simulation of Multihourly Precipitation Extremes
Publisher: American Meteorological Society
Abstract: xtreme value theory is used as a diagnostic for two high-resolution (12-km parameterized convection and 1.5-km explicit convection) Met Office regional climate model (RCM) simulations. On subdaily time scales, the 12-km ...
Do Convection-Permitting Regional Climate Models Improve Projections of Future Precipitation Change?
Publisher: American Meteorological Society
Abstract: egional climate projections are used in a wide range of impact studies, from assessing future flood risk to climate change impacts on food and energy production. These model projections are typically at 12?50-km resolution, ...
Greater Future U.K. Winter Precipitation Increase in New Convection-Permitting Scenarios
Publisher: American Meteorological Society
Abstract: For the first time, a model at a resolution on par with operational weather forecast models has been used for national climate scenarios. An ensemble of 12 climate change projections at convection-permitting (2.2 km) scale ...
The Effect of Explicit Convection on Couplings between Rainfall, Humidity, and Ascent over Africa under Climate Change
Publisher: American Meteorological Society
Abstract: The Hadley circulation and tropical rain belt are dominant features of African climate. Moist convection provides ascent within the rain belt, but must be parameterized in climate models, limiting predictions. Here, we use ...
Implications of Improved Representation of Convection for the East Africa Water Budget Using a Convection-Permitting Model
Publisher: American Meteorological Society
Abstract: AbstractThe precipitation and diabatic heating resulting from moist convection make it a key component of the atmospheric water budget in the tropics. With convective parameterization being a known source of uncertainty ...
