Vertical Structure of Tropical Waves Maintained by Internally-Induced Cumulus Heating
Publisher: American Meteorological Society
Abstract: Solutions to the wave-CISK (conditional instability of the second kind with cumulus heating being induced by low-level internal wave convergence) system are obtained to study the vertical structure of orginally unstable ...
Forcing of Stratospheric Kelvin Waves by Tropospheric Heat Sources
Publisher: American Meteorological Society
Abstract: The problem of scale-selection of Kelvin waves in the stratosphere by forcing from tropospheric heating is analyzed using a simple linear model. The effect of vertical wind shear is excluded because the phase speed of the ...
On the Depth of the Equatorial Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: The solutions of the linear equatorial boundary layer are evaluated and found to be dependent on both the depth of the modelled boundary layer and the mode of symmetry about the equator. The inclusion of the frictional ...
Viscous Internal Gravity Waves and Low–Frequency Oscillations in the Tropics
Publisher: American Meteorological Society
Abstract: In this paper we deal with the interpretation of observed oscillations in the tropical troposphere and stratosphere within the framework of the equatorial wave theory. A difficulty with this problem arises when one compares ...
Westward Propagating Cloud Patterns in the Tropical Pacific as seen from Time-Composite Satellite Photographs
Publisher: American Meteorological Society
Abstract: A new method of using satellite photographs in the study of large-scale cloud motions in the tropics is presented. Cloud clusters are seen to be propagating westward with a phase speed ?9 m sec?1 in the summer of 1967, and ...
A Numerical Study of the Interaction between the Large-Scale Monsoon Circulation and Orographic Precipitation over South and Southeast Asia
Publisher: American Meteorological Society
Abstract: regional climate model is used to simulate the summer monsoon onset in South and Southeast Asia during the year 2000 to explore the interaction between orographic precipitation and the large-scale monsoon circulation. In ...
Unusual Late-Season Cold Surges during the 2005 Asian Winter Monsoon: Roles of Atlantic Blocking and the Central Asian Anticyclone
Publisher: American Meteorological Society
Abstract: The highest frequency of late-winter cold-air outbreaks in East and Southeast Asia over 50 years was recorded in 2005, when three strong successive cold surges occurred in the South China Sea within a span of 30 days from ...
