Analysis and Application of Data Obtained by Wind Profiler Radar on the Coast of South China

A comparison of data detected by wind profiler and balloon-mounted radars revealed no significant differences between the two types under conditions of weak wind power. The variation rules of space and time were studied by using the data of wind profiler radar at the seaside of Huilai. The results show that the wind profiler radar has stronger detecting capability on the vertical structure of three-dimensional winds and can detect sea-land breeze vertical shear in real time. Such data could be used to analyze the rules of pollutant diffusion and migration in coastal areas. In addition, data obtained by the wind profiler radar was studied to determine the rule of periphery wind shear of Typhoon Chanthu. The results show that the wind profiler radar also has stronger detecting capability on the typhoon peripheral sinking airflow area of high-altitude wind in a three-dimensional wind vertical structure. Moreover, this type of radar can detect the rules of typhoon space shear in real time to improve the efficiency of the typhoon prevention in coastal areas.
