Computation of Climatological Vertical Velocities by the Thermodynamic Method
نویسنده
چکیده
Vertical velocities compatible with climatological heating functions are computed. The physical assumptions in the thermodynamic equation incorporate radiational heating, heat flux from the underlying boundary, and heat of condensation. The computation is performed for the four seasons, and a comparison with other studies indicates that the method gives fairly good results that may be related to climatological cloudiness and rainfall.

The power of vertical geolocation of atmospheric profiles from GNSS radio occultation
High-resolution measurements from Global Navigation Satellite System (GNSS) radio occultation (RO) provide atmospheric profiles with independent information on altitude and pressure. This unique property is of crucial advantage when analyzing atmospheric characteristics that require joint knowledge of altitude and pressure or other thermodynamic atmospheric variables. Here we introduce and demo...
متن کاملImprovement of vertical and residual velocities in pressure or hybrid sigma-pressure coordinates in analysis data in the stratosphere
Stratospheric vertical winds from analysis data in pressure (p) or hybrid pressure (σ -p) coordinates, for use in e.g. chemical transport models (CTMs) or trajectory models, often suffer both from excessive noise and errors in their mean magnitude, which in turn can introduce errors in important dynamical quantities like vertical mixing or constituent transport with the residual circulation. Si...

Thermodynamic analysis of a steady state flow and heat transfer of an Oldroyd 8-constant fluid with effect of heat source, velocity slip and buoyancy force under tranverse a magnetic field is is carried out in this paper. The model for momentum and energy balance is tackled numerically using Method of Weighted Residual (MWR). Partition method is used to minimize the associated residuals. The re...
متن کاملVelocity Modeling in a Vertical Transversely Isotropic Medium Using Zelt Method
In the present paper, the Zelt algorithm has been extended for ray tracing through an anisotropic model. In anisotropic media, the direction of the propagated energy generally differs from that of the plane-wave propagation. This makes velocity values to be varied in different directions. Therefore, velocity modeling in such media is completely different from that in an isotropic media. The vel...
