Typhoon Bavi’s recent landfall in China, which triggered the evacuation of nearly two million people and caused severe flooding, highlights the increasing frequency of extreme weather events in the region. According to reports from Yahoo News and MoneyDJ, the storm brought 10-meter waves and significant infrastructure damage, marking the second major typhoon to strike the country within a single week.
The Physical Impact of Consecutive Storms
MoneyDJ reports that Bavi’s second landfall led to immediate river surges and widespread urban flooding. Beyond the immediate water damage, the storm’s physical footprint has been unusual; social media footage cited by PChome Online captured significant amounts of marine debris and waste being washed back onto Chinese shores by the massive waves, a visual reminder of the ocean’s role in circulating human-made waste during high-energy weather events.
Environmental Anomalies and Forecasting Challenges
In Hangzhou, residents reported the sky turning a distinct shade of pinkish-purple shortly before landfall, a phenomenon captured in accounts shared by the United Daily News.
According to SET News, the typhoon’s path left behind a "cold water wake"—a trail of significantly cooler sea surface temperatures. Experts cited by the outlet suggest this creates a challenging environment for subsequent storms, as the depletion of surface heat energy alters the thermodynamic potential for following weather systems, effectively creating a "trap" for future typhoons that might attempt to follow a similar trajectory.

Frequently Asked Questions
Why do typhoons sometimes cause the sky to change color?
What is a "cold water wake" and why does it matter?
A cold water wake is a patch of cooler ocean surface temperature left behind after a storm. Because hurricanes and typhoons rely on warm water as "fuel," this cooler area can act as a natural brake for future storms.
