RISUsing Satellite Observations to Constrain Parameterizations of Gravity Wave Effects for Global Models
Publisher: American Meteorological Society
Abstract: Small-scale gravity waves are common features in atmospheric temperature observations. In satellite observations, these waves have been traditionally difficult to resolve because the footprint or resolution of the measurements ...
Summer Season Squall-Line Simulations: Sensitivity of Gravity Waves to Physics Parameterization and Implications for Their Parameterization in Global Climate Models
Publisher: American Meteorological Society
Abstract: ravity waves have important effects on the middle atmosphere circulation, and those generated by convection are prevalent in the tropics and summer midlatitudes. Numerous case studies have been carried out to investigate ...
Linear Stratospheric Gravity Waves above Convective Thermal Forcing
Publisher: American Meteorological Society
Abstract: The spectra of linear gravity waves generated by a time-varying tropospheric thermal forcing representing organized convection are compared to the spectra of stratospheric gravity waves generated by organized convection ...
Model Study of Intermediate-Scale Tropical Inertia–Gravity Waves and Comparison to TWP-ICE Campaign Observations
Publisher: American Meteorological Society
Abstract: 2-day inertia?gravity wave (IGW) was observed in high-resolution radiosonde soundings of horizontal wind and temperature taken during the 2006 Tropical Warm Pool?International Cloud Experiment (TWP-ICE) experiment in the ...
The Residual-Mean Circulation in the Tropical Tropopause Layer Driven by Tropical Waves
Publisher: American Meteorological Society
Abstract: atent heating estimates derived from rainfall observations are used to construct model experiments that isolate equatorial waves forced by tropical convection from midlatitude synoptic-scale waves. These experiments are ...
On the Intermittency of Gravity Wave Momentum Flux in the Stratosphere
Publisher: American Meteorological Society
Abstract: n this article, long-duration balloon and spaceborne observations, and mesoscale numerical simulations are used to study the intermittency of gravity waves in the lower stratosphere above Antarctica and the Southern Ocean; ...
Tropical Precipitation Variability and Convectively Coupled Equatorial Waves on Submonthly Time Scales in Reanalyses and TRMM
Publisher: American Meteorological Society
Abstract: ropical precipitation characteristics are investigated using the Tropical Rainfall Measuring Mission (TRMM) 3-hourly estimates, and the result is compared with five reanalyses including the European Centre for Medium-Range ...
Solutions to the Vertical Structure Equation for Simple Models of the Tropical Troposphere
Publisher: American Meteorological Society
Abstract: bservation and modeling studies indicate that the wave flux from tropical heating sources that propagates into the lower stratosphere is sensitive to the buoyancy frequency profile N(z) in the troposphere. This sensitivity ...
Characteristics of Gravity Waves from Convection and Implications for Their Parameterization in Global Circulation Models
Publisher: American Meteorological Society
Abstract: haracteristic properties of gravity waves from convection over the continental United States are derived from idealized high-resolution numerical simulations. In a unique modeling approach, waves are forced by a realistic ...
Latitudinal Variations Observed in Gravity Waves with Short Vertical Wavelengths
Publisher: American Meteorological Society
Abstract: Knowledge of the latitudinal variations in the occurrence of gravity waves is important for their parameterization in global models. Observations of gravity waves with short vertical scales have shown a pronounced peak in ...
