Seminar has concluded. Please refer to the Event Wrap-Up below.<\/strong><\/p>\n\n\t\tEvent Wrap-Up\n\t<\/h2>\n\tThank you for joining us at CFI Singapore’s recent seminar featuring Professor Seon Ki Park from Ewha Womans University, South Korea.\nProf. Park, a renowned expert in severe storm and climate modeling, delivered an insightful session on the complex dynamics driving coastal heavy rainfall along South Korea’s eastern coast. Drawing from high-resolution mesoscale simulations, he examined the role of mountainous topography, typhoon interactions, and the Kor’easterlies in two significant extreme weather events.\nHis talk highlighted the influence of mesoscale convective systems (MCS) and terrain-induced mechanisms-contributing to our understanding of flood resilience and informing future coastal modeling efforts.\nWe also extend our appreciation to Professor Shie-Yui Liong, Advisor to CFI Singapore, for chairing the seminar, and to all participants for your active engagement.\n

\n\t\tAbstract\n\t<\/h2>\n\t
Coastal cities in South Korea, especially in the east coast, often experiences heavy precipitation events affected by terrain, i.e., the Taebaek Mountains (TM), and winds blowing from the East Seacalled the Kor’easterlies. Cities are located on a narrow coast along the TM. Here, two extreme rainfall events are analyzed in the coastal cities using the mesoscale model simulations: case A induced by a typhoon circulation, and case B related to a mesoscale convective system (MCS). <\/p>\n
In case A, a coastal city, Gangneung, underwent a record-breaking 24-hr accumulated rainfall of 870.5 mm under the influence of Typhoon Rusa (2002) in late August. It was mainly caused by the followings: 1) strong low-level convergence of moist air by the Kor’easterlies into the coastal area; 2) consequent orographic lifting over the TM; and 3) release of potential instability to trigger deep convection. <\/p>\n
In case B, a back-building MCS produced a daily rainfall of 226.2 mm on 6 August 2018 via the following mechanisms: 1) low-level convergence by the Kor’easterlies, carrying moist air into the coast; 2) strong vertical wind shear, making the updraft tilted and sustained; 3) coastal fronts and back-building convection bands, formed through interactions among the Kor’easterlies, cold pool outflows, and orography; 4) mid-level advection of cold air and positive relative vorticity, enhancing vertical convection and potential instability; and 5) vigorous updraft releasing potential instability.<\/p>\n
