Probabilistic Forecast of Visibility at Gimpo, Incheon, and Jeju International Airports Using Weighted Model Averaging
Autor: Hee-Wook Choi, Keunhee Han, Chansoo Kim
Publikováno v: Atmosphere, Vol 13, Iss 12, p 1969 (2022)
In this study, weighted model averaging (WMA) was applied to calibrating ensemble forecasts generated using Limited-area ENsemble prediction System (LENS). WMA is an easy-to-implement post-processing technique that assigns a greater weight to the ens

Probabilistic Forecast of Low Level Wind Shear of Gimpo, Gimhae, Incheon and Jeju International Airports Using Ensemble Model Output Statistics
Autor: Hee-Wook Choi, Yeon-Hee Kim, Keunhee Han, Chansoo Kim
Publikováno v: Atmosphere, Vol 12, Iss 12, p 1643 (2021)
Wind shear can occur at all flight levels; however, it is particularly dangerous at low levels, from the ground up to approximately 2000 feet. If this phenomenon can occur during the take-off and landing of an aircraft, it may interfere with the norm

Inter-Comparison of Ensemble Forecasts for Low Level Wind Shear against Local Analyses Data over Jeju Area
Autor: Young-Gon Lee, Sang-Boom Ryoo, Keunhee Han, Hee Wook Choi, Chansoo Kim
Publikováno v: Atmosphere, Vol 11, Iss 2, p 198 (2020)
Ensemble verification of low-level wind shear (LLWS) is an important issue in airplane landing operations and management. In this study, we conducted an accuracy and reliability analysis using a rank histogram, Brier score, and reliability diagram to

Comparison of Statistical Post-Processing Methods for Probabilistic Wind Speed Forecasting
Autor: JunTae Choi, Keunhee Han, Chansoo Kim
Publikováno v: Asia-Pacific Journal of Atmospheric Sciences. 54:91-101
In this study, the statistical post-processing methods that include bias-corrected and probabilistic forecasts of wind speed measured in PyeongChang, which is scheduled to host the 2018 Winter Olympics, are compared and analyzed to provide more accur

Comparison of prediction performance using statistical postprocessing methods
Autor: Chansoo Kim, JunTae Choi, Keunhee Han
Publikováno v: Asia-Pacific Journal of Atmospheric Sciences. 52:495-507
As the 2018 Winter Olympics are to be held in Pyeongchang, both general weather information on Pyeongchang and specific weather information on this region, which can affect game operation and athletic performance, are required. An ensemble prediction
