Typhoon Nuri, known in the Philippines as Typhoon Paeng, was the third most intense tropical cyclone worldwide in 2014. Nuri developed into a tropical storm and received the name Paeng from the PAGASA on October 31, before it intensified into a typhoon on the next day. Under excellent conditions, especially the synoptic scale outflow, Nuri underwent rapid deepening and reached its peak intensity on November 2, forming a round eye in a symmetric CDO. Having maintained the impressive structure for over one day, the typhoon began to weaken on November 4, with a cloud-filled eye.

Because of increasing vertical wind shear from the mid-latitude westerlies, Nuri lost the eye on November 5, and deep convection continued to diminish. The storm accelerated northeastward and completely became extratropical on November 6. However, on November 7, Nuri’s circulation split, and the new center absorbed the storm.

A low-pressure area formed approximately 590 km (365 mi) east-southeast of Guam early on October 28, and a tropical disturbance formed within the area on the next day. After having slowly consolidated for two days, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert to the system on October 30, for its quickly consolidating but broad low-level circulation center (LLCC) under a favorable environment. Additionally, the Japan Meteorological Agency (JMA) upgraded the low-pressure area to a tropical depression at noon on the same day. The agency upgraded the system to a tropical storm and named it Nuri early on October 31, shortly after the JTWC upgraded it to a tropical depression and designated it as 20W. Under low vertical wind shear and good outflow, a central dense overcast (CDO) started to flare over the LLCC with the tighter wrapped banding, prompting the JTWC upgrading Nuri to a tropical storm in the afternoon. As it entered the Philippine Area of Responsibility, the PAGASA named it Paeng at 23:00 PST (15:00 UTC).
