RISFrom CMIP3 to CMIP6: Northern Hemisphere Atmospheric Blocking Simulation in Present and Future Climate
Publisher: American Meteorological Society
Abstract: A comprehensive analysis of the representation of winter and summer Northern Hemisphere atmospheric blocking in global climate simulations in both present and future climate is presented. Three generations of climate models ...
Northern Hemisphere Atmospheric Blocking Representation in Global Climate Models: Twenty Years of Improvements?
Publisher: American Meteorological Society
Abstract: he correct simulation of midlatitude atmospheric blocking has always been a main concern since the earliest days of numerical modeling of Earth?s atmosphere. To this day blocking represents a considerable source of error ...
Impact of Anomalous Ocean Heat Transport on the North Atlantic Oscillation
Publisher: American Meteorological Society
Abstract: Coupled atmosphere?ocean dynamics in the North Atlantic is studied by means of a simple model, featuring a baroclinic three-dimensional atmosphere coupled to a slab ocean. Anomalous oceanic heat transport due to wind-driven ...
Coherent Structures in Large-Eddy Simulations of a Nonprecipitating Stratocumulus-Topped Boundary Layer
Publisher: American Meteorological Society
Abstract: AbstractThe properties of coherent convective structures are analyzed in a nonprecipitating marine nocturnal stratocumulus-topped boundary layer (STBL) with a series of high-resolution large-eddy simulations (LESs). A new ...
Linking Warm Arctic Winters, Rossby Waves, and Cold Spells: An Idealized Numerical Study
Publisher: American Meteorological Society
How Do Ocean Warm Anomalies Favor the Aggregation of Deep Convective Clouds?
Publisher: American Meteorological Society
Abstract: We investigate the role of a warm sea surface temperature (SST) anomaly (hot spot of typically 3 to 5 K) on the aggregation of convection using cloud-resolving simulations in a nonrotating framework. It is well known that ...
Hot European Summers and the Role of Soil Moisture in the Propagation of Mediterranean Drought
Publisher: American Meteorological Society
Abstract: Drought in spring and early summer has been shown to precede anomalous hot summer temperature. In particular, drought in the Mediterranean region has been recently shown to precede and to contribute to the development of ...
Triggering Deep Convection with a Probabilistic Plume Model
Publisher: American Meteorological Society
Abstract: model unifying the representation of the planetary boundary layer and dry, shallow, and deep convection, the probabilistic plume model (PPM), is presented. Its capacity to reproduce the triggering of deep convection over ...
Stationary Atmospheric Responses to an Idealized Sea Surface Temperature Anomaly in the Southern Ocean
Publisher: American Meteorological Society
Abstract: he stationary atmospheric response to an idealized sea surface temperature anomaly (SSTA) is studied with a quasigeostrophic atmospheric model of the Southern Hemisphere. Sensitivity of the stationary response to the ...
Surface and Atmospheric Controls on the Onset of Moist Convection over Land
Publisher: American Meteorological Society
Abstract: he onset of moist convection over land is investigated using a conceptual approach with a slab boundary layer model. The authors determine the essential factors for the onset of boundary layer clouds over land and study ...
