one Principle and significance of lightning monitoring and early warning system
one point one Lightning warning principle
The essence of lightning is that there are constantly changing charges in the thundercloud. In addition, lightning will also have an impact on the electromagnetic field strength when it appears. The lightning weather can be judged according to the change of electromagnetic field intensity, and at the same time, the historical lightning strike data information and self mastered knowledge can be introduced to judge the impact range, start and end time, location information, etc. of the lightning weather. On the basis of relevant equipment software, the real-time monitoring of the change information of thunderstorm cloud on the ground electric field strength is carried out. By setting the electromagnetic field strength standard, once the value reaches a certain standard, the early warning equipment will send out an alarm signal message, reminding that lightning will occur in the area in the future, which is called lightning early warning.
one point two Principle of lightning monitoring and early warning system
In fact, a lightning monitoring and early warning system can be formed by combining the lightning early warning network and the ground electric field instrument, which can monitor the lightning weather in real time and send early warning information to the corresponding area after the lightning weather is found. There are many similarities between lightning potential system and ground flash detection system, both of which can give real-time warning to ground flash location information. When lightning occurs, it will produce electromagnetic waves. The relevant statistical practice results show that the electromagnetic waves radiated by cloud to ground lightning are not very different. Based on this principle, the number of detection points can be appropriately increased to achieve the time required for the monitoring waveform feature points to reach the detection station, so that the cloud to ground flash warning level can be greatly improved.
one point three Significance of lightning warning system
Lightning is a kind of severe convective weather and a serious natural disaster phenomenon. In the process of building a lightning monitoring and early warning system, local weather and climate conditions should be considered. When conducting lightning early warning, it is necessary to combine sounding data, ground observation data, lightning data, etc., and actively introduce modern instruments and equipment to further improve the lightning early warning system essence Degree level. Because the ground electric field instrument can only realize short-term lightning weather early warning, the lightning monitoring and early warning system can visually observe and forecast the lightning weather. In particular, long-term lightning observation can ensure that observers understand the activity rules of local thunderstorm weather, and the obtained data information can provide data support for the study of the relationship between small and medium-sized thunderstorms and ground electric fields. In the process of building a lightning monitoring and early warning system, we should always take into account the lightning service business system, ensure that lightning data information can be transmitted and shared normally in the corresponding industries, and further enhance the level of lightning protection and disaster reduction in the region. In addition, the establishment of lightning monitoring and early warning system can improve the essence The level of timeliness plays a very important role in carrying out lightning protection and disaster reduction work and ensuring social safety production, which can reduce casualties and property losses caused by lightning.
Level I early warning: in the process of thunderstorm formation, lightning may occur, prompting operators to pay attention to possible thunderstorms, and notifying them to pay attention and prevent.
Level II early warning: when thunderstorm is about to occur, further confirm the information. At this time, the lightning flash time is at least about thirty About minutes, remind users that they can take safety protection plans to avoid lightning damage.
Level III early warning: lightning will occur soon, and the system will be automatically operated. At this time, the time from lightning flash to occur is about ten About minutes, pop up and remind the user to take safety protection measures to avoid lightning damage.
