Abstract:On 21 March 2019, an instantaneous maximum wind speed of 60.3 m·s-1 was recorded at 21:13 BT by national observation station in Lingui District, Guangxi. On 13 April 2019, an instantaneous maximum wind speed of 50.7 m·s-1 was recorded at 14:11 BT by observation station in He’an Town, Guangdong Province. Significant wind damages were observed at the two places. By analyzing surveillance video, drone aerial data, site survey and visiting witnesses, the following conclusions were obtained. The wind damage which occurred at Lingui National Station and its surrounding area from 21:09 BT to 21:14 BT was a EF2 microburst lasting at least 6 minutes and affecting 1.6 km×2.0 km. It belonged to micro α scale microburst and contained seven micro β scale embedded. The damage area was featured with small aspect ratio, discontinuous spatial distribution and divergent wind pattern. The wind damage that occurred in Xuwen of Guangdong Province from 14:09 BT to 14:15 BT was a EF3 tornado which lasted for 7 minutes. The damage path was about 3.2 km long and 30-280 m wide. The surveillance video showed that there was a rotational wind tunnel existing shortly near the damage site. Compared with Lingui microburst, the damage area has larger aspect ratio, more continuous spatial distribution and convergent wind pattern.
