Introduction


      The 23rd Olympic Winter Games and the 13th Paralympic Winter Games will be held in PyeongChang, Korea on February 9-25 and March 9-18 respectively, 2018. The Winter Games are great opportunities to understand severe winter weather over complex terrain areas and to improve the predictability of nowcasting and very-short range forecasting.

      The World Weather Research Program (WWRP) of the World Meteorological Organization (WMO) has approved and supported several international projects such as Forecast Demonstration Project (FDP) and Research and Development Project (RDP) to enhance the capability of member countries in the area of convective scale numerical weather prediction modeling, and to understand the high impact weather systems.

      KMA (Korea Meteorological Administration) and NMC (Numerical Modeling Center) have a responsibility to provide weather information for the management of the Games and the safety of the public. To accomplish this mission, NMC will carry out RDP/FDP for PyeongChang 2018 Winter Olympic Game named ICE-POP 2018 (International Collaborative Experiments for Pyeongchang 2018 Olympic and Paralympic winter games). These projects focus on intensive observation campaigns to understand severe winter weathers over the PyeongChang region, and the research results from RDP will be used to improve the accuracy of nowcasting and very-short-range forecast systems, which will be run in real time and the forecast will be provided to forecasters during the Games.

Goal and scientific challenge in the ICE-POP2018




      The goal of the ICE-POP 2018 is advancing seamless prediction from nowcasting to short-range forecast for winter weathers over complex terrains based on an intensive observation campaign. The scientific challenges related to the goal are;

1) to understand orographic effects in complex terrain considering small scales wind flow and its interaction with a large scale flow, vertical structure specifically at a lower level where snows forms and phased changes related to the wind flow and vertical structures,

2) to study the ocean-air interaction in the east bound of the PyeongChang such as moisture and heat flow, and low level rolling cloud formation process depending on the flow pattern and air-sea temperature difference.

3) to improve the prediction of low level wind, poor visibility, and precipitation amount and type through improved understanding in physical processes over the region and demonstrating the usefulness of the observations.
