摘　　要：0814(黑格比)和9615(莎莉)是登陆粤西沿岸的强台风,台风路径相似、强度相同、登陆点相近,两次台风均造成珠江口内高潮位,而前者形成超高潮位。通过现有资料的比较,对两场台风特点及产生风暴潮灾害程度不同的原因进行分析。0814台风造成珠江口内特高潮位的原因主要有:1.台风强度,0814台风低压控制时间较9615台风长;2.天文潮大小,0814台风登陆日珠江口外天文潮潮差超过9615台风25%;3.登陆时所遇天文潮涨落阶段不同,0814台风登陆时逢珠江口内处于高潮位时,而9615登陆时珠江口内处于落潮过程。Intense typhoon 0814 （Hagupit）, which landed at the west Guangdong coast with similar track, comparable magnitude and close landing site of typhoon 9615 （Sally）, caused super high water level in the Peal River Estuary in history. Based on observed data, we find aspects resulting in the historical highest water level in the estuary due to Hagupit as follows： （1） the low pressure control period of Hagupit was longer than that of Sally. （2） Hagupit landed with larger declination tide. Although both typhoons landed around middle tide periods, Hagupit happened to coincide with larger declination tide than typhoon Sally. （3） Hagupit landed with flood tide. The period of 4 hours before Hagupit landing happened to be flooding with huge amount of water pumped into the Peal River Estuary. On the contrast typhoon Sally landed around the ebb period.
