As one of the aero-exploring system,wind profiler already gradually dives into the test of scientific research and the probation of operation in our country,but the wind profiler requires high electromagnetic environment in the around of the location of wind profiler.

In order to improve the measurement velocity and precision of signal processor of wind profiler, a solution of software and hardware proposed which can process signal at real -time.

Wind profilers are used for detecting the wind distribution of the atmosphere.

Wind profiles in and over trees;

The result indicated that threshold wind velocity of soil erosion is non-linearly and positively related to shrub coverage;and the wind profile is influenced remarkably by shrub coverage;wind erosion rate increases exponentially with the coverage reduction;there exists power relationship between aerodynamic roughness length and shrub coverage,as well as displacement height.

With the help of the algorithm presented in this paper, the effects on the trajectories of the saltating grains and the wind velocity profiles are displayed and analyzed for the interaction between wind and grains and the other factors such as aerodynamic lift, Magnus effect, and electrostatic force.

It was found that for a given condition of underlying surface,pattern of wind velocity profile in sand flow conforms to the form of power function =azb and its power exponent is about 0.

Data diversity in multi-mode detection of wind profile and integration strategy

Wind measurement data processing system is to tie in with the wind profile equipment in the aviation meteorological services and applications.

In this paper,we present the structural design of a P-band wind profile radar and give a detailed introduction to the main parts of its structure.
