Typhoon Dolphin struck eastern China this week, triggering severe flooding and the evacuation of more than one million people [1].
The storm's impact on one of the world's busiest economic hubs demonstrates the vulnerability of coastal urban infrastructure to intensifying tropical cyclones.
The storm made landfall on Sunday with Force 13 winds reaching 85 mph [4]. While the system weakened as it moved inland, it retained enough intensity to produce torrential rain and strong winds across eastern China and surrounding provinces [2, 5].
Authorities coordinated the evacuation of more than one million people to mitigate casualties from the rising waters [1]. The resulting flooding paralyzed transportation networks, particularly in the aviation sector. Hundreds of flights were grounded across the eastern region [1], with nearly 950 flights canceled in Shanghai alone [2, 3].
The weather patterns shifted rapidly following the storm's passage. While eastern provinces dealt with the aftermath of the deluge, Hong Kong experienced a period of sweltering heat [1, 2].
Local officials said the storm left a trail of extreme weather in its wake, moving from violent winds to heavy rain and eventually extreme heat in different regions [1]. The combination of high-velocity winds and sudden rainfall created a high-risk environment for residents in low-lying areas of Shanghai and neighboring provinces [3, 5].
“More than one million people evacuated”
The scale of the evacuations and the disruption to Shanghai's aviation hub highlight the systemic risk that tropical cyclones pose to China's eastern seaboard. The rapid transition from typhoon-strength winds to extreme heat in nearby Hong Kong underscores the volatile atmospheric instability characterizing current weather patterns in the region.
