Typhoon Damrey was a compact tropical cyclone, which became the strongest to affect the area north of the Yangtze River since 1949. It was the tenth named storm and the fifth typhoon of the 2012 Pacific typhoon season. The name Damrey means elephant in Khmer, the official language of Cambodia.
Damrey developed into a tropical storm north of the Tropic of Cancer on July 28 and drifted slowly. By late on July 30, Damrey began to accelerate west-northwestward. The storm struggled to make deep convection wrap around itself due to vertical wind shear and dry air since formation, until it passed near Kyushu on August 1. Damrey finally intensified into a typhoon early on August 2, a half of day before it made landfall over the northern Jiangsu.
Late on July 26, a tropical disturbance formed southwest of Minamitorishima, which was originally associated with the divergent north of a tropical upper tropospheric trough (TUTT). On July 27, as the original TUTT cell weakened, an upper-level anticyclone was building on the system. Although not being a fully warm-core system initially, it intensified into a tropical depression according to the Japan Meteorological Agency (JMA), when sea surface temperature ranged from 29 to 31°C. However, the low-level circulation center (LLCC) became exposed later. On July 28, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert on the system, before JMA upgraded it to a tropical storm and named it Damrey. Late on the same day, JTWC upgraded Damrey to a tropical depression, with a partially exposed LLCC under moderate northwesterly vertical wind shear.
