Thunderstorm cloud point charge positioning data complementation method based on atmospheric electric field instrument array group

Abstract

The invention discloses a thunderstorm cloud point charge positioning data complementation method based on an atmospheric electric field instrument array group. The method comprises the specific steps: firstly, building an atmospheric electric field instrument electric field component measurement model, and defining azimuth parameters of thunderstorm cloud point charges; according to a mirror image method principle, obtaining thunderstorm cloud point charge coordinates by utilizing a potential distribution formula, the positioning parameters comprising a horizontal deflection angle and an elevation angle, and also comprising the distance from an electric field instrument to thunderstorm cloud; and taking the main electric field instrument as a reference, building the atmospheric electric field instrument array group. According to the thunderstorm cloud point charge positioning data complementation method based on the atmospheric electric field instrument array group, the data measuredby each electric field instrument is subjected to complementation processing, and the thunderstorm cloud point charge position is obtained again, so that the problem that data loss or distortion can generate adverse effects on the accuracy and stability of thunderstorm cloud point charge positioning is effectively solved; and results show that the method can accurately reflect the orientation of the thunderstorm cloud point charge, and has a good positioning effect.

Description

technical field [0001] The invention relates to the technical field of thunderstorm cloud detection, in particular to a thunderstorm cloud point charge positioning data complementary method based on an array group of atmospheric electric field instruments. Background technique [0002] Thunderstorm clouds are cumulonimbus clouds produced after a certain intensity, while thunder and lightning are produced by the accumulation of electric charges in thunderstorm clouds. With the development of social modernization, effects such as electrostatic induction caused by lightning will cause immeasurable losses to the social economy. The large current and strong electromagnetic radiation generated during lightning discharge will cause damage to ground forests, buildings, power electronic equipment, communication systems, etc., and even endanger personal safety. Therefore, an effective thunderstorm cloud detection method will help reduce lightning hazards. [0003] In the field of me...
