Wind profile in the planetary boundary layer during morning hours over a tropical semi-arid station

چکیده
The land surface processes associated with heat and momentum, govern the heating of atmospheric boundary layer (ABL) in morning hours. In present study, we investigate structure wind ABL depicted hours its role establishing ABL. For this purpose, Radiosonde/Radiowind observations collected during Land Surface Processes Experiment (LASPEX) over tropical station Anand, India, have been used. It is observed that profiles changed from one season to another form rotation prominent low level jet (LLJ) stream. During monsoon season, LLJ played a significant double mixing line elevated wind-backing layer.

Analytical Solution of The Laminar Boundary Layer Flow over Semi-Infinite Flat Plate: Variable Surface Temperature
In this paper, the problem of forced convection over a horizontal flat plate under condition of variable plate temperature is presented and the homotopy perturbation method (HPM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing the problem. This paper provides good supplements to the existing literature and generalizes the previ...
متن کاملPlanetary Boundary Layer Turbulence
In previous chapters boundary layers were evident as thin layers across which thermal, dynamic, and material properties of a free interior flow make a transition to their boundary values and/or boundary fluxes. In those cases the thinness of the boundary layer was typically a statement of the smallness of the relevant diffusivity; e.g., the depth h of the laminar Ekman boundary layer scales as ...
متن کاملDimensional Analysis Applied to the Wind Distribution in the Planetary Boundary Layer
In an attempt to understand the implications of Long's " generalized dimensional analysis, " this method was applied to the problem of the wind distribution in the planetary boundary layer. The assumption was made that the equations of motion, together with an appropriate set of boundary conditions, define a unique relationship among the wind, the stress, and certain other variables and paramet...
متن کاملHigh-level Warmings Over a Tropical Station
Examination of the available rocketsonde data for the tropical station, Thumba, India, has shown that warmings, less pronounced than in the case of middleand high-latitude stations but of noticeable magnitude, and coolings of similar magnitude occurred in the mesopheric and upper stratospheric levels during the period, December 1970-htarch 1971. This was the only winter period when observations...
متن کاملTropical Cyclone Boundary Layer Shocks
This paper presents numerical solutions and idealized analytical solutions of axisymmetric, f -plane models of the tropical cyclone boundary layer. In the numerical model, the boundary layer radial and tangential flow is forced by a specified pressure field, which can also be interpreted as a specified gradient balanced tangential wind field vgr(r) or vorticity field ζgr(r). When the specified ...
