However, with regard to lightning forecasts, meteorological forecasts are still in the process of being researched, and it is still rough that weather forecasts are added by adding weather conditions to trends due to movement of lightning spots, and lightning warning devices that monitor only one point are installed. The reality is that you can only get forecasts of lightning strikes.

へ緊急避難を促す等の行動をとればよい。When a wide range of lightning observation signals are received from the above-mentioned lightning observation radar RD, first, a lightning strike warning signal is transmitted to the slave station information processing device in the thundercloud generation monitoring area. Further, a lightning strike warning signal is transmitted to the slave station information processing device included in the region forming the electric field distribution of the positive electrode based on the ground electric field distribution data due to the development of the thundercloud thereafter. More specifically, in the thundercloud occurrence monitoring area, to the slave station information processing device of the slave station that has been positively determined even once in the positive electrode or the negative electrode,
Automatically sends a lightning strike warning signal. In the vicinity of the slave station that receives the lightning strike warning signal, it can be understood that the possibility of lightning strike is extremely high after 20 to 30 minutes, and therefore the staff member should immediately take actions such as urging people on the course to make an emergency evacuation.

It was found from the observation result of the ground electric field distribution before the start of the lightning strike by comparing the ground electric field distribution with the lightning strike location system (LPATS) and the meteorological radar. Since the behavior of lightning strikes is still under study, further data collection is needed in the future, and although it has not been fully clarified yet, it is effective for detecting a local thundercloud occurrence and providing a lightning forecast.
