Stratospheric Gravity Wave Fluxes and Scales during DEEPWAVE
(American Meteorological Society, 2016)uring the Deep Propagating Gravity Wave Experiment (DEEPWAVE) project in June and July 2014, the Gulfstream V research aircraft flew 97 legs over the Southern Alps of New Zealand and 150 legs over the Tasman Sea and Southern ... -
Aerosol Impacts on Thermally Driven Orographic Convection
(American Meteorological Society, 2016)bservations from the Dominica Experiment (DOMEX) field campaign clearly show aerosols having an impact on cloud microphysical properties in thermally driven orographic clouds. It is hypothesized that when convection is ... -
Warm Cores, Eyewall Slopes, and Intensities of Tropical Cyclones Simulated by a 7-km-Mesh Global Nonhydrostatic Model
(American Meteorological Society, 2016)ased on the data of a 1-yr simulation by a global nonhydrostatic model with 7-km horizontal grid spacing, the relationships among warm-core structures, eyewall slopes, and the intensities of tropical cyclones (TCs) were ... -
What Flow Conditions are Conducive to Banner Cloud Formation?
(American Meteorological Society, 2016)anner clouds are clouds that are attached to the leeward slope of a steep mountain. Their formation is essentially due to strong Lagrangian uplift of air in the lee of the mountain. However, little is known about the flow ... -
Analytical Infrared Delta-Four-Stream Adding Method from Invariance Principle
(American Meteorological Society, 2016)he single-layer solutions using a four-stream discrete ordinates method (DOM) in infrared radiative transfer (IRT) have been obtained. Two types of thermal source assumptions?Planck function exponential and linear dependence ... -
Atmospheric Response to a Midlatitude SST Front: Alongfront Winds
(American Meteorological Society, 2016)atellite observations and modeling studies show that midlatitude SST fronts influence the marine atmospheric boundary layer (MABL) and atmospheric circulation. Here, the Weather Research and Forecasting (WRF) mesoscale ... -
Weak Jets and Strong Cyclones: Shallow-Water Modeling of Giant Planet Polar Caps
(American Meteorological Society, 2016)iant planet tropospheres lack a solid, frictional bottom boundary. The troposphere instead smoothly transitions to a denser fluid interior below. However, Saturn exhibits a hot, symmetric cyclone centered directly on each ... -
Growth and Decay of a Convective Boundary Layer over a Surface with a Constant Temperature
(American Meteorological Society, 2016)he growth and decay of a convective boundary layer (CBL) over a surface with a constant surface temperature that develops into a linear stratification is studied, and a mathematical model for this system is derived. The ... -
An Analysis of Gravity Wave Spectral Characteristics in Moist Baroclinic Jet–Front Systems

Moisture and Precipitation Evolution during Tropical Cyclone Formation as Revealed by the SSM/I–SSMIS Retrievals
(American Meteorological Society, 2016)he simultaneous precipitation and column water vapor retrievals from the SSM/I and SSMIS passive microwave instruments were used to examine the convective and moisture evolution during tropical cyclone formation. Using a ... -
Limitations of One-Dimensional Mesoscale PBL Parameterizations in Reproducing Mountain-Wave Flows
(American Meteorological Society, 2015)esoscale models are considered to be the state of the art in modeling mountain-wave flows. Herein, the authors investigate the role and accuracy of planetary boundary layer (PBL) parameterizations in handling the interaction ... -
A Unified Theory for the Great Plains Nocturnal Low-Level Jet
(American Meteorological Society, 2016)theory is presented for the Great Plains low-level jet in which the jet emerges in the sloping atmospheric boundary layer as the nocturnal phase of an oscillation arising from diurnal variations in turbulent diffusivity ... -
Natural and Anthropogenic Aerosol Trends from Satellite and Surface Observations and Model Simulations over the North Atlantic Ocean from 2002 to 2012
(American Meteorological Society, 2016)erosols contribute to Earth?s radiative budget both directly and indirectly, and large uncertainties remain in quantifying aerosol effects on climate. Variability in aerosol distribution and properties, as might result ... -
