Problems solved by technology
In the past, data on thunderstorm days usually came from manual observations. For many observation stations, observation data for decades are often kept. The accumulation of observation data takes a long time, and the data are also very valuable.
However, the observation results of manual observation of thunderstorm days are easily affected by factors such as the environment of meteorological stations, hearing differences of observers, and background noise

The invention provides a method for calculating the number of thunderstorm days by using lightning location data. The method comprises the steps of acquiring lightning location data and historical thunderstorm day records of a lightning observation area the radius, wherein the radius of the lightning observation area is R and an observation point is used as the center; selecting n observation ranges the radii of which is Rn from the lightning observation area, wherein Rn is less than or equal to R, and obtaining thunderstorm day records in each observation range from the lightning location data; matching thunder and lightning day records in each observation range with the thunderstorm day records during the historical thunderstorm day recording period, and using the observation range withthe smallest error between the thunder and lightning day records and the thunderstorm day records as a matched observation range; in the matched observation range, using the number of thunder and lightning days obtained from the thunder and lightning day records in the matched observation range as the number of the thunderstorm days. According to the method, by studying a relationship between theobservation radii and the thunderstorm day records, the thunder and lightning days can be observed through an instrument to obtain the thunderstorm record information, and previous records obtained bymanually observing the thunderstorm days are saved.
Description
technical field [0001] The invention relates to the field of meteorological observation, in particular to a method for calculating the number of thunderstorm days by using lightning location data. Background technique [0002] As we all know, thunderstorm days are physical parameters that reflect the frequency and intensity of local lightning activities. In the past, the data of thunderstorm days usually came from manual observations. For many observatories, observation data of decades were often kept, and the accumulation of observation data took a long time, and the data was also very valuable. However, the observation results of manual observation of thunderstorm days are easily affected by factors such as the environment of meteorological stations, hearing differences of observers, and background noise. [0003] With the increasing modernization of meteorological observation, the lightning location observation system is gradually replacing the observation method of conv...
