Embodiment 2

[0036] refer to figure 1 , the lightning early warning method based on radar data, comprises the following steps:

[0037] S1. Use radar to monitor lightning in the monitoring area, and transmit a set of monitoring data to the control center every 6s. The control center classifies the received data, classifies the radar data, and calculates the similarity of the data after classification. The similarity is greater than 97% of the data is regarded as duplicate data, which is directly eliminated. The number of radars is 2. The radars are marked, and the data transmitted by different radars are compared to judge the accuracy of the radar detection data. The phase state of the particles in the cloud is detected by the radar , arrangement orientation, spatial distribution and scale spectrum for detection;

[0038] S2, extracting the historical lightning data and lightning monitoring data of the radar monitoring area;

[0039] S3. Perform lightning simulation based on radar monito...

Embodiment 3

[0044] refer to figure 1 , the lightning early warning method based on radar data, comprises the following steps:

[0045] S1. Use radar to monitor the monitoring area for lightning, and transmit a set of monitoring data to the control center every 7s. The control center classifies the received data, classifies the radar data, and calculates the similarity of the data after classification. The similarity is greater than 97% of the data is regarded as duplicate data, which is directly eliminated. The number of radars is 3. The radars are marked, and the data transmitted by different radars are compared to judge the accuracy of the radar detection data. The phase state of the particles in the cloud is detected by the radar , arrangement orientation, spatial distribution and scale spectrum for detection;

Embodiment 4

[0050] refer to figure 1 , the lightning early warning method based on radar data, comprises the following steps:

[0051] S1. Use radar to monitor the monitoring area for lightning, and transmit a set of monitoring data to the control center every 8s. The control center classifies the received data, classifies the radar data, and calculates the similarity of the data after classification. The similarity is greater than 97% of the data is regarded as duplicate data, which is directly eliminated. The number of radars is 3. The radars are marked, and the data transmitted by different radars are compared to judge the accuracy of the radar detection data. The phase state of the particles in the cloud is detected by the radar , arrangement orientation, spatial distribution and scale spectrum for detection;

Abstract

The invention discloses a lightning early warning method based on radar data, and the method comprises the following steps: S1, detecting radar data, classifying the radar data, and removing repeated data; s2, extracting historical thunder and lightning data and thunder and lightning monitoring data of the radar monitoring area; s3, lightning simulation is carried out according to radar monitoring data and historical data; s4, performing grade judgment on the simulated thunder and lightning, and performing early warning in different modes according to different grades; s5, monitoring thunder and lightning occurrence time and thunder and lightning grades after early warning, and recording monitoring data; and S6, comparing the monitored thunder and lightning occurrence time and thunder and lightning level with early warning data, performing difference degree calculation, and evaluating early warning accuracy. Thunder and lightning early warning can be effectively performed, and evaluation of early warning accuracy is facilitated.

Description

technical field [0001] The invention relates to the technical field of lightning early warning methods, in particular to a lightning early warning method based on radar data. Background technique [0002] In recent years, the degree of harm caused by lightning disasters has been increasing, and the resulting impact on society and economic losses have also increased. Therefore, effective monitoring, forecasting and research of lightning activities have very important practical significance for the smooth advancement of lightning protection and disaster reduction work. [0003] In the prior art, lightning early warning cannot be performed based on radar data, so we propose a lightning early warning method based on radar data to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to solve the disadvantages in the prior art that lightning warning cannot be carried out based on radar data, and propose a lightning warning method ...
