Typhoon Bavi triggered a rare “reverse waterfall” phenomenon at the Dalongqiu Waterfall in Yandang Mountain, Zhejiang province, on July 11, 2026. As the storm brought winds exceeding ten levels, the water flow was forced upward against the mountain face, creating a visual effect of water surging toward the sky.
Impact of Typhoon Bavi on Yandang Mountain
The meteorological conditions caused by Typhoon Bavi led to the temporary closure of the Yandang Mountain scenic area. According to park staff, the sites including Lingfeng, Lingyan, and Dalongqiu were closed starting at 6:00 p.m. on July 9, with no immediate date provided for reopening.
The typhoon’s path involved two separate landfalls in the region. The storm first made landfall on the coast of Kanmen Street, Yuhuan City, at approximately 11:20 p.m. on July 11. It subsequently made a second landfall near Qingjiang Town in Yueqing City, Wenzhou, at approximately 12:00 a.m. on July 12. At the time of the second landfall, the typhoon recorded maximum wind speeds of 13 levels (38 meters per second) and a minimum central pressure of 960 hectopascals.
Did You Know?
Dalongqiu Waterfall is recognized for having the highest single-stage drop in China, measuring 197 meters. Its appearance frequently shifts based on seasonal changes, rainfall, and wind conditions.
Implications for Local Infrastructure
The “reverse waterfall” effect occurs when extreme wind pressure overcomes the gravitational force typically driving the water downward from the Lianyunzhang cliff. While such phenomena are visually notable, they are a direct consequence of the high-velocity winds accompanying the typhoon’s landfall in the Wenzhou area.
Frequently Asked Questions
What caused the waterfall to flow backward?
The phenomenon was caused by strong winds from Typhoon Bavi, which reached over ten levels in intensity, forcing the water flow upward instead of its natural downward path.
When did the typhoon make landfall in the area?
The typhoon made its first landfall at 11:20 p.m. on July 11 in Yuhuan and a second landfall around midnight on July 12 in Yueqing.
Is the Yandang Mountain scenic area currently open?
No. The scenic area has been closed since 6:00 p.m. on July 9, and the reopening date remains to be determined.
Have you ever observed how extreme weather conditions can alter the appearance of natural landmarks?
