Sensitivity of Atlantic Tropical Storm Frequency to ENSO and Interdecadal Variability of SSTs in an Ensemble of AGCM Integrations
Publisher: American Meteorological Society
Abstract: A significant reduction (increase) of tropical storm activity over the Atlantic basin is observed during El Niño (La Niña) events. Furthermore, the number of Atlantic tropical storms displays an interdecadal variability ...
Uncertainties of Estimates of Inertia–Gravity Energy in the Atmosphere. Part II: Large-Scale Equatorial Waves
Publisher: American Meteorological Society
Abstract: This paper analyzes the spectra and spatiotemporal features of the large-scale inertia-gravity (IG) circulations in four analysis systems in the tropics. Of special interest is the Kelvin wave (KW), which represents between ...
Uncertainties of Estimates of Inertia–Gravity Energy in the Atmosphere. Part I: Intercomparison of Four Analysis Systems
Publisher: American Meteorological Society
Abstract: This paper presents the application of the normal-mode functions to diagnose the atmospheric energy spectra in terms of balanced and inertia?gravity (IG) contributions. A set of three-dimensional orthogonal normal modes ...
Balance of the Background-Error Variances in the Ensemble Assimilation System DART/CAM
Publisher: American Meteorological Society
Abstract: his paper quantifies the linear mass?wind field balance and its temporal variability in the global data assimilation system Data Assimilation Research Testbed/Community Atmosphere Model (DART/CAM), which is based on the ...
Small-Scale Structure of a Coastal Front as Revealed by Dual-Doppler Radar
Publisher: American Meteorological Society
Abstract: The analysis of the rainband structure and wind fields associated with a coastal front along the North Carolina shoreline is described. Dual-Doppler radar and the augmented GALE (Genesis of Atlantic Lows Experiment) ensemble ...
Impact of Large-Scale Circulation on Tropical Storm Frequency, Intensity, and Location, Simulated by an Ensemble of GCM Integrations
Publisher: American Meteorological Society
Abstract: Tropical storms simulated by a nine-member ensemble of GCM integrations forced by observed SSTs have been tracked by an objective procedure for the period 1980?88. Statistics on tropical storm frequency, intensity, and ...

The Boundary Layer Response to Recent Arctic Sea Ice Loss and Implications for High-Latitude Climate Feedbacks
Publisher: American Meteorological Society
Abstract: This study documents and evaluates the boundary layer and energy budget response to record low 2007 sea ice extents in the Community Atmosphere Model version 4 (CAM4) using 1-day observationally constrained forecasts and ...
Simulation of Interannual Variability of Tropical Storm Frequency in an Ensemble of GCM Integrations
Publisher: American Meteorological Society
Abstract: The present study examines the simulation of the number of tropical storms produced in GCM integrations with a prescribed SST. A 9-member ensemble of 10-yr integrations (1979?88) of a T42 atmospheric model forced by observed ...
