Embodiment Construction
[0088] In this embodiment, the radar base data in the Nanjing area during the time period from 05:39 to 07:11 on August 10, 2016 is selected as the experimental object.
[0089] Step 1) Read the radar base data at 06:10 and the previous 5 moments of the day. For the convenience of expression, define these base data as BD(T), BD(T-1), BD(T-2), BD (T-3), BD(T-4), BD(T-5). The base data of this radar is in CINRADSA format, the volume scanning time interval is 6 minutes, and the number of effective detection elevation angles of the basic reflectivity is 9.
[0090] Step 2) Read the basic reflectivity values of each detection elevation angle in BD(T). Define the basic reflectance value of a certain elevation angle as BRV(T,a,b,c), where a represents the elevation angle, and a∈[0.5°,1.5°,2.4°,3.4°,4.3°,6.0°,9.9 °, 14.6°, 19.5°]; b represents the azimuth, and b∈[0,360); c represents the range library number detected by the radar, and c∈[1,MaxDis], the value of MaxDis depends on t...
