Typhoon Bavi
Overview
Typhoon Bavi (바비) was the 8th typhoon of 2020, a powerful tropical cyclone that directly impacted the Korean Peninsula. Forming in the northwestern Pacific, it moved northward along the west coast of the Korean Peninsula, bringing heavy rain and strong winds particularly to the Jeolla and Chungcheong regions, resulting in casualties and property damage. Typhoon Bavi was one of several typhoons that struck the Korean Peninsula in the summer of 2020 and remains a key case in discussions about the increasing intensity of typhoons related to climate change.

Formation and Development
Typhoon Bavi developed from a tropical disturbance east of the Philippines around August 22, 2020, gradually strengthening into a typhoon. The Japan Meteorological Agency (JMA) and the Joint Typhoon Warning Center (JTWC) designated it as the 8th typhoon, with maximum sustained winds of approximately 40 m/s (144 km/h), classifying it as "very strong." The typhoon intensified as it moved northward along the edge of the North Pacific high-pressure system, maintaining a powerful state with a central pressure dropping to 950 hPa as it approached the Korean Peninsula.
Path and Impact
Typhoon Bavi moved northward along the west coast of the Korean Peninsula between August 26 and 27, 2020. Its main path passed west of Jeju Island, approached the coast of South Jeolla Province, then moved through South Chungcheong Province and western Gyeonggi Province before exiting into North Korea. During this process, the Jeolla and Chungcheong regions, located in the typhoon's right semicircle (danger semicircle), experienced particularly strong winds and heavy rain. Maximum instantaneous wind speeds exceeded 50 m/s on Jeju Island, and winds of around 40 m/s were observed in areas such as Yeosu and Goheung in South Jeolla. Rainfall ranged from 100 to 300 mm depending on the region, with some mountainous areas receiving over 400 mm.
Damage Situation
Damage from Typhoon Bavi was primarily concentrated on strong winds and heavy rain. In South Jeolla and South Chungcheong provinces, signboards were damaged, trees were uprooted, and power outages occurred, with significant damage to crops (especially rice and fruit trees). Coastal areas reported vessel flooding and aquaculture farm damage due to high waves and storm surges. Human casualties included one death and two missing persons, with approximately 1,500 displaced individuals. Additionally, the typhoon caused widespread cancellations of flights and ferry operations, and landslides and flooding occurred in some areas.
Response and Recovery
The South Korean government activated the Central Disaster and Safety Countermeasures Headquarters in preparation for Typhoon Bavi and conducted preemptive evacuations of residents in high-risk areas. Notably, quarantine measures were strengthened at shelters due to the COVID-19 pandemic. After the typhoon, emergency recovery operations were carried out, and compensation and support were provided to affected farming households. This process revealed both the efficiency and limitations of the disaster response system, which were later reflected in improvements to typhoon preparedness manuals.
Latest Trends
As of 2024–2025, Typhoon Bavi is frequently mentioned in climate change research as one of the typhoons that affected the Korean Peninsula in 2020. Recent studies indicate that the intensity of typhoons forming in the northwestern Pacific is increasing due to global warming, with the average wind speed and rainfall of typhoons approaching the Korean Peninsula analyzed to have increased by 10–15% compared to the past. Typhoon Bavi is a representative example of this trend, cited in the 2024 IPCC report as an illustration of the increasing typhoon risk on the Korean Peninsula. Furthermore, in 2025, the Korea Meteorological Administration improved its typhoon prediction models, strengthening early warning systems for typhoons with paths similar to Typhoon Bavi. Concurrently, disaster prevention facilities (such as breakwaters and drainage systems) have been reinforced in areas affected by Typhoon Bavi, and the development of typhoon-resistant crop varieties is accelerating in the agricultural sector.
