Protection zone
Based on the calculation of factors such as the speed, range, spacing between operation points and rocket impact radius of the weather system, it is necessary to set up the first line of defense at a distance of 6h~4h(t) from the system to the protection zone: set up the second line of defense at a distance of 4h~3h(t) from the system to the protection zone: set up the third line of defense at a distance of 3h~2h(ts) from the system to the protection zone. The distance (D) between the defense line and the protection zone is calculated as shown in formula (A.1): D=uXt
Where:
System movement speed, unit is thousand techniques per day (ikin/h); time to move to the protection zone, unit is hour (h). The calculation steps are as follows:
a) According to radar echo statistics, the cloud system moves at a speed of 30h. It can be calculated that the first line of defense is 170km~110km away from the protected area (D); the second line of defense is 120km85km~10km away from the protected area (D).
10km (D,); the third line of defense is 10km away from the protected area (D,). b) According to the angle of each wind direction is 22.5°, set the defense line at an angle of 30°, and set the length of the first defense line as L2Lz = 170km × tan (30°/2) × 2 ~ 91km, so the length of the first defense line is set to 90km ~ 150km. Suppose the length of the second defense line is L2Lz = 125km × tan (30°/2) × 2 ~ 67km, then the defense line is set to 60km ~ 120km. Suppose the length of the third front line is Ls; L, = 80km × tan (30/2) × 2 ~ 43km, then the defense line is set to 20km ~ 60km. c) According to the width of the general precipitation cloud echo 6 = 30km, considering that two rows of rocket points are required for operation, the defense line width (W) should be at least about 60km.
QX/T492—2019
B.1 Operation interval
Appendix B
(Informative Appendix)
Ground operation intervals and methods for artificial rain reduction According to the different distances between the three lines of defense for artificial rain reduction activities on a certain day and the operation protection zone, the rocket operation trajectory is used as the line source, and its diffusion width is used as the protection range to calculate the impact width of rocket operations on different lines of defense. According to the calculation results, the impact width of the rocket for the first line of defense is about 9km, the impact width of the rocket for the second line of defense is about 6km~7km, and the impact width of the rocket for the third line of defense can be considered to be about 3km~4km. In general, the first line of defense has the longest interval operation time, and the second and third lines gradually reduce the operation interval. Usually, the first line of defense has an operation interval of about 30min, the second line of defense is 10min~15min, and the third line is 5min~10min. B.2
Operation method
Ground operations should be carried out vertically in the direction of cloud movement. Industry Standard Information Service Platform
