Some Preliminary Theoretical Considerations of Tropospheric Wave Motions in Equatorial Latitudes
نویسنده
چکیده
Wave solutions to the linearized, quasi-hydrostatic equations for adiabatic, nonviscous flow on an equatorially oriented beta plane are obtained. The basic current is assumed to be zonal and invariant in both space and time. Only solutions for which the meridional wind component is symmetric with respect to the equator are considered. Disturbances with wavelengths on the order of 103 km. are found to be very nearly nondivergent. The solutions show the meridional wind component to be very nearly geostrophic even at very low latitudes. The perturbation of the zonal wind, however, is highly ageostrophic at the very low latitudes and significantly ageostrophic even in subtropical latitudes.

Further Theoretical Considerations of Tropospheric Wave Motions in Equatorial Latitudes
The known general solution of the system of linearized equations for non-viscous, adiabatic, quasi-hydrostatic flow on an equatorially oriented @-plane is examined in detail for various boundary conditions imposed on the motion. The base state is a space-time invariant zonal current. The particular solutions examined are those in which the meridional wind component is distributed either symmetr...
متن کاملSensitivity of the tropical nonlinear stationary Kelvin and Rossby waves to the vertical structure of heating
Idealized experiments using linear (LM) and nonlinear (NM) multilevel global spectral models have been carried out to investigate and understand the impact of nonlinearities on the stationary wave response in the tropical atmosphere and its sensitivity to the vertical profile of heating. It is found that nonlinearities exert a dominant influence on the low-latitude stationary Kelvin and Rossby ...
متن کاملPlanetary-scale Characteristics of Monthly Mean Long-wave Radiation and Albedo and Some Year-to-year Variations
Global patterns of monthly averages of outgoing long-wave radiation and albedo as derived from TIROS IV radiometer data for the period February-May 1962 are examined relative to each other and with respect to monthly mean mid-tropospheric flow patterns. It is found that long-wave radiation and albedo are inversely correlated on a broad scale, particularly over ocean and non-desert regions. Both...
متن کاملFeedbacks between the isentropic slope and wave generation at tropospheric levels and implications for stratosphere/troposphere coupling
Extratropical tropospheric variability is investigated during Northern Hemisphere winter in the context of feedbacks between the meridional slope of the isentropic surfaces and the generation of eddy activity in the lower troposphere. The results reveal that at mid-high latitudes, periods of anomalously large tropospheric eddy heat fluxes (and thus wave generation) are preceded by anomalously s...
