Abstract: The theory of generalized Hough modes developed in a companion paper is applied here to investigate the structure of the migrating diurnal tide in the mesosphere and lower thermosphere. A series of simple examples illustrate ...

Abstract: The technique of classical tidal theory in which linear disturbances to a background flow at rest are expanded in terms of Hough modes is generalized for damped disturbances to a general zonal mean state under the assumption ...

Abstract: The terdiurnal, or 8-h, tide has been seen in a number of midlatitude radar measurements and has recently been mapped globally at 95 km. A series of calculations and model simulations are used to examine the processes ...

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 ...

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 ...

Abstract: onvective heating profiles are computed from one month of rainfall rate and cloud-top height measurements using global Tropical Rainfall Measuring Mission and infrared cloud-top products. Estimates of the tropical wave ...

Abstract: quatorial atmospheric waves in the upper troposphere and lower stratosphere (UTLS), excited by latent heating, are investigated by using a global spectral model. The latent heating profiles are derived from the 3-hourly ...

Abstract: AbstractUsing an idealized model framework with high-frequency tropical latent heating variability derived from global satellite observations of precipitation and clouds, the authors examine the properties and effects of ...
