The Charge Structure of a Typical Thunderstorm in Chinese Inland Plateau
Six-station measurements on electric field change of lightning flashes were carried out in the northeastern verge of Tibet Plateau. The height and magnitude of charge neutralized by return strokes have been fitted. According to the electric field changes of cloud-to-ground (CG) flashes in a typical thunderstorm with a larger-than-usual lower positive charge center (LPCC), a total of 65 return strokes of 16 negative CG and 2 positive CG flashes have been analyzed.The results showed that the height of charge region neutralized by negative CG flashes ranged from 3 km to 5 km above the ground. For the two positive CG flashes, the neutralized charge regions were located in a height from 5 km to 6 km. This was the first evidence of upper positive charge in the thunderstorm with larger-than-usual LPCC. The triple charge structure of thunderstorm in Chinese Inland Plateau was confirmed consequently.
