Memories of Wind Disasters in the 20th Century: From Painful Lessons to Enhanced Defense
Looking back at Hong Kong's meteorological history, the first half of the 20th century saw typhoons often cause catastrophic consequences due to limited monitoring technology and weak disaster prevention infrastructure. Among these, the severe typhoon of 1937 remains one of the deadliest wind disasters on record in Hong Kong. Historical records indicate that the storm's fierce winds and heavy rain, combined with a powerful storm surge, caused numerous ships to sink and inundated low-lying coastal areas with seawater, with the estimated death toll reaching the tens of thousands. This tragedy profoundly revealed the vulnerability of early cities in the face of extreme weather and served as a wake-up call for the subsequent development of disaster prevention systems.
Entering the era of modern meteorological observation, Typhoon "Wanda" in 1962 became the benchmark for the strongest storm to hit Hong Kong after World War II. Wanda approached the Pearl River Estuary head-on as a severe typhoon, prompting the Hong Kong Observatory to hoist the No. 10 Hurricane Signal for nearly two days. Its core characteristics included extremely low pressure and high wind speeds, with Tate's Cairn recording a gust of 284 km/h, a record that remains unbroken to this day. More fatally, Wanda triggered a severe storm surge, causing water levels in Victoria Harbour to rise sharply. This led to widespread flooding along the coasts of the New Territories and Kowloon, resulting in collapsed houses, destroyed farmland, and significant casualties and economic losses. The Wanda disaster directly drove comprehensive upgrades in Hong Kong's wind-resistant building standards, warning mechanisms, and coastal protection engineering.
Recent Extreme Challenges and Scientific Responses
In the 21st century, although urban defense capabilities have significantly improved, the increasing uncertainty in typhoon intensity and tracks under the background of climate change has brought new challenges. Super Typhoon "Hato" in 2017 is a typical example. Hato made landfall in Zhuhai as a severe typhoon, posing a serious threat to Hong Kong. The strong northeasterly winds it brought, superimposed on an astronomical high tide, caused severe flooding in parts of Macau and Zhuhai, while Hong Kong also recorded record-breaking storm surge levels. This event highlighted the destructive power of the "triple threat" of wind, rain, and tides, prompting Guangdong, Hong Kong, and Macau to further strengthen cooperation in storm surge warnings and cross-border emergency response.
It is worth noting that judging the severity of a typhoon depends not only on wind force but also on comprehensive factors such as storm surges, rainfall, and geological risks. In recent years, Super Typhoon "Mangkhut" in 2018, although it did not make direct landfall, still dealt a devastating blow to Hong Kong with its massive circulation and extremely low-pressure center. It uprooted trees, paralyzed infrastructure, and halted social operations for several days. These cases indicate that even in modern cities, the highest level of vigilance is required when facing top-tier typhoons.
It should be emphasized that the assessment of typhoon disaster impacts involves complex meteorological data and socio-economic indicators. For specific disaster statistics and government emergency response measures, please refer to official information released by local governments and meteorological departments. The public should develop the habit of paying attention to authoritative warnings in daily life, stockpile emergency supplies in advance, and familiarize themselves with evacuation routes.
