Hong Kong witnessed a record number of lightning strikes last Saturday, data from the Observatory showed.
Most of the lightning strikes, including both cloud-to-ground and cloud-to-cloud types, centered on Lantau island and New Territories East, the Hong Kong Economic Journal reports.
A spectacular photo taken by a local resident and posted on a Facebook page shows a lightning hitting the sea surface from the sky.
The Observatory said the number of lightning strikes, most of which belonged to the cloud-to-ground type, reached as many as 7,887 on Saturday, the most in one day so far this year.
Including the 5,235 strikes between midnight and 7 p.m. Sunday, the total number of lightning strikes over the weekend was 13,122.
The historical one-day record was seen on Sept. 9, 2010, when there were more than 14,000 cloud-to-ground lightning strikes.
The great number of lightning strikes over the weekend is believed to have been influenced by Typhoon Nepartak, which slammed eastern Taiwan last Friday before it weakened and entered southeastern China’s Fujian province.
The Observatory issued a thunderstorm warning between 6:45 p.m. Saturday and 6:45 a.m. Sunday.
Within those 12 hours, Lantau saw 3,229 lightning strikes, more than any other district in the city, Apple Daily reported.
Wong Wai-kin, senior scientific officer of the Observatory, said the thunderstorm was mainly caused by high temperature resulting from the downdraft of a tropical cyclone near Hong Kong and then led to intensive lightning strikes, according to am730 newspaper.
