Storm type

Tropical cyclone

Subtropical cyclone

Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression

An area of convection developed approximately 250 miles east of Pohnpei late on August 13. By August 16, the disturbance had passed 40 miles north of Chuuk. It developed enough organization to be designated a tropical depression on August 19, about 400 miles west of Guam. From there, it moved northwest at 12 mph along the southwestern periphery of a mid-level steering ridge. The system reached tropical storm status on August 20, gaining the name Aere. ^[2]

Aere subsequently crossed into the Philippine Area of Responsibility, and was assigned the name Marce. Tropical Storm Aere was upgraded to typhoon intensity on August 21, and its strength leveled off during August 21 and August 22. On August 23, the typhoon was briefly downgraded to a tropical storm due to vertical wind shear while located 200 miles south of Naha, Okinawa. Aere quickly regained typhoon status and maintained its intensity for the rest of August 23 and developed a 50-mile wide eye. The tropical cyclone reached its peak intensity of 85 kn (98 mph) late on August 24, when the pressure lowered to 955 mb.^{[ citation needed ]}

As the storm crossed the northern tip of Taiwan, it began to weaken. Typhoon Aere turned west-southwestward on August 25 and made its closest approach to Taipei, Taiwan, passing only 30 miles to the city's north. Aere turned southwestward later that day, a trajectory that carried the storm past Xiamen early the next day and close to Shantou later that day before weakening to tropical storm intensity. The remnants of Typhoon Aere remained a tropical depression until August 31.^{[ citation needed ]}
