- Abstract
The Korean Integrated Model (KIM) was developed for global weather forecasting at the first Phase (2011–2019) of the Korea Institute of Atmospheric Prediction Systems (KIAPS), and it has become the operational model of the Korea Meteorological Administration (KMA) since April 2020. To improve the predictability beyond 2 weeks, it is necessary to better represent the physical process and interaction between the atmosphere and surface. Therefore, the KIAPS Phase 2 project (2021–2026) aims to advance the land surface model and to newly couple the ocean/sea-ice/wave/riverrouting models to the operational KIM. At the first stage (2020–2022), ocean (the Nucleus for European Modelling of the Ocean; NEMO) and sea-ice (Sea Ice modelling Integrated Initiative; SI3) models were successfully coupled to KIM by means of the own coupler based on Model Coupling Toolkit. The evaluation result showed that the performance of the KIM coupled version is promising on medium-range forecast as well as seasonal simulations when compared to the uncoupled version. The state-of-the-art land surface models, Noah with multiple parameterization (NoahMP) and community land model (CLM), became optional to explicitly consider the geographical processes within snow and canopy layers. In addition, the river-routing (Catchment-based Macro-scale Floodplain; CMF) and wave (Wave Watch III; WW3) models were coupled at a preliminary stage and their sensitivity are being explored. The second stage (2023–2026) involves building an ‘fully coupled operational model at
variable resolution’ that would allow KIM to enable a seamless prediction of weather and climate. To this end, KIAPS is trying to advance the dynamical/physical processes in the coupled modeling
system, construct an ensemble-based robust evaluation system, and introduce a (weakly) coupled data assimilation system. This seminar will cover the current status and future plan of the new KIM
focusing on the coupled modeling system.
