RISThe Interannual Variability of Energy Transports within and over the Atlantic Ocean in a Coupled Climate Model
Publisher: American Meteorological Society
Abstract: To gain a new perspective on the interaction of the Atlantic Ocean and the atmosphere, the relationship between the atmospheric and oceanic meridional energy transports is studied in a version of HadCM3, the U.K. Hadley ...
Bjerknes Compensation and the Decadal Variability of the Energy Transports in a Coupled Climate Model
Publisher: American Meteorological Society
Abstract: In the 1960s, Jacob Bjerknes suggested that if the top-of-the-atmosphere (TOA) fluxes and the oceanic heat storage did not vary too much, then the total energy transport by the climate system would not vary too much either. ...
Can Polar Lows be Objectively Identified and Tracked in the ECMWF Operational Analysis and the ERA-Interim Reanalysis?
Publisher: American Meteorological Society
Abstract: olar lows are maritime mesocyclones associated with intense surface wind speeds and oceanic heat fluxes at high latitudes. The ability of the Interim ECMWF Re-Analysis (ERA-Interim, hereafter ERAI) to represent polar lows ...
Can Climate Models Capture the Structure of Extratropical Cyclones?
Publisher: American Meteorological Society
Abstract: Composites of wind speeds, equivalent potential temperature, mean sea level pressure, vertical velocity, and relative humidity have been produced for the 100 most intense extratropical cyclones in the Northern Hemisphere ...
The Ability of CMIP5 Models to Simulate North Atlantic Extratropical Cyclones
Publisher: American Meteorological Society
Abstract: he ability of the climate models participating in phase 5 of the Coupled Model Intercomparison Project (CMIP5) to simulate North Atlantic extratropical cyclones in winter [December?February (DJF)] and summer [June?August ...

Northern Hemisphere Extratropical Cyclones in a Warming Climate in the HiGEM High-Resolution Climate Model
Publisher: American Meteorological Society
Abstract: hanges to the Northern Hemisphere winter (December?February) extratropical storm tracks and cyclones in a warming climate are investigated. Two idealized climate change experiments with the High Resolution Global Environmental ...
Atmospheric Impact of Arctic Sea Ice Loss in a Coupled Ocean–Atmosphere Simulation
Publisher: American Meteorological Society
Abstract: he atmospheric response to an idealized decline in Arctic sea ice is investigated in a novel fully coupled climate model experiment. In this experiment two ensembles of single-year model integrations are performed starting ...
Extreme Daily Rainfall in Pakistan and North India: Scale Interactions, Mechanisms, and Precursors
Publisher: American Meteorological Society
Abstract: AbstractWhile much of India is used to heavy precipitation and frequent low pressure systems during the summer monsoon, toward the northwest and into Pakistan, such events are uncommon. Here, as much as a third of the ...
Representation of Western Disturbances in CMIP5 Models
Publisher: American Meteorological Society
Abstract: AbstractWestern disturbances (WDs) are synoptic extratropical disturbances embedded in the subtropical westerly jet stream. They are an integral part of the South Asian winter climate, both for the agriculture-supporting ...
