A Stochastic Skeleton Model for the MJO
(American Meteorological Society, 2013)he Madden?Julian oscillation (MJO) is the dominant mode of variability in the tropical atmosphere on intraseasonal time scales and planetary spatial scales. Despite the primary importance of the MJO and the decades of ... -
Simulated Convective Invigoration Processes at Trade Wind Cumulus Cold Pool Boundaries
(American Meteorological Society, 2014)bservations of precipitating trade wind cumuli show convective invigoration on the downwind side of their cold pools. The authors study convection and cold pools using a nested?Weather Research and Forecasting Model ... -
Barotropic and Baroclinic Annular Variability in the Southern Hemisphere
(American Meteorological Society, 2013)he leading patterns of large-scale climate variability in the Southern Hemisphere are examined in the context of extratropical kinetic energy. It is argued that variability in the Southern Hemisphere extratropical flow can ... -
Multiscale Interactions in an Idealized Walker Circulation: Mean Circulation and Intraseasonal Variability
(American Meteorological Society, 2013)high-resolution cloud-resolving model (CRM) simulation is developed here for a two-dimensional Walker circulation over a planetary-scale domain of 40 000 km for an extended period of several hundred days. The Walker cell ... -
Influence of the Background Wind on the Local Soil Moisture–Precipitation Feedback
(American Meteorological Society, 2013)he importance of soil moisture anomalies on airmass convection over semiarid regions has been recognized in several studies. The underlying mechanisms remain partly unclear. An open question is why wetter soils can result ... -
The Atmospheric Response to Surface Heating under Maximum Entropy Production
(American Meteorological Society, 2014)n numerous studies, midlatitude storm tracks have been shown to shift poleward under global warming scenarios. Among the possible causes, changes in sea surface temperature (SST) have been shown to affect both the intensity ... -
Detecting and Classifying Events in Noisy Time Series
(American Meteorological Society, 2013)ime series are characterized by a myriad of different shapes and structures. A number of events that appear in atmospheric time series result from as yet unidentified physical mechanisms. This is particularly the case for ... -
The Sensitivity of Springtime Arctic Mixed-Phase Stratocumulus Clouds to Surface-Layer and Cloud-Top Inversion-Layer Moisture Sources
(American Meteorological Society, 2013)n this study, a series of idealized large-eddy simulations is used to understand the relative impact of cloud-top and subcloud-layer sources of moisture on the microphysical?radiative?dynamical feedbacks in an Arctic ... -
The Atmospheric General Circulation in Thermodynamical Coordinates
(American Meteorological Society, 2013)he zonal and meridional components of the atmospheric general circulation are used to define a global thermodynamic streamfunction in dry static energy versus latent heat coordinates. Diabatic motions in the tropical ... -
A Total Flow Perspective of Atmospheric Mass and Angular Momentum Circulations: Boreal Winter Mean State
(American Meteorological Society, 2014)his paper reports a comprehensive diagnostic analysis of mass and angular momentum (AM) circulations and their budgets in boreal winter using the 32-yr daily NCEP?Department of Energy (DOE) reanalysis (1979?2010). The ... -
The Linkage between the Warm and the Cold Conveyor Belts in an Idealized Extratropical Cyclone
(American Meteorological Society, 2013)his study continues the investigation of airstreams in idealized moist baroclinic waves and addresses the formation of the cold conveyor belt (CCB), its linkage to the warm conveyor belt (WCB), and their impact on the ... -

Observations of Temperature, Wind, Cirrus, and Trace Gases in the Tropical Tropopause Transition Layer during the MJO
(American Meteorological Society, 2013)atellite observations of temperature, optically thin cirrus clouds, and trace gases derived from the Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC), Cloud?Aerosol Lidar and Infrared Pathfinder ... -
The Formation of Wider and Deeper Clouds as a Result of Cold-Pool Dynamics
(American Meteorological Society, 2014)his study investigates how precipitation-driven cold pools aid the formation of wider clouds that are essential for a transition from shallow to deep convection. In connection with a temperature depression and a depletion ... -
Convective Cells in Altocumulus Observed with a High-Resolution Radar
(American Meteorological Society, 2014)ery-high-resolution Doppler radar observations are used together with aircraft measurements to document the dynamic and thermodynamic structure of a dissipating altocumulus cloud system associated with a deep virga layer. ... -
Mesoscale Gravity Waves in Moist Baroclinic Jet–Front Systems
(American Meteorological Society, 2013)series of cloud-permitting simulations with the Weather Research and Forecast model (WRF) are performed to study the characteristics and source mechanisms of mesoscale gravity waves in moist baroclinic jet?front systems ... -
Development of an Intense, Warm-Core Mesoscale Vortex Associated with the 8 May 2009 “Super Derecho” Convective Event
