APCC and PNU paper on the spatiotemporal characteristics of Human-Perceived Temperature (HPT) data in South Korea attracts public attention.
A research team, formed by scientists from the APEC Climate Center (APCC) and Pusan National University (PNU), wrote a research paper entitled “Human-Perceived Temperature Change in South Korea and Their Association with Atmospheric Circulation Patterns”. The research paper, published in the Journal of Climate, recently attracted public attention and media.※ Paper link : https://doi.org/10.1175/JCLI-D-20-0344.1The research team investigated the spatiotemporal characteristics of human-perceived temperature (HPT) data, which describe the joint effects of temperature and humidity on the human body, and examined the related large-scale atmospheric circulation patterns for the summer season (July–August) in South Korea using trend and composite analyses.The increasing trend of HPT was stronger than that of the maximum, mean, and minimum temperatures during 1981–2018. There was an abrupt change in HPT between 1981–2009 and 2010–18, which is likely caused by the northward upper-level subtropical jet, strengthened downward motion, anomalous anticyclones around South Korea, and increased sea surface temperature over the western North Pacific Ocean, which are related to the enhancement and western expansion of the western North Pacific subtropical high (WNPSH).Dr. Hyun-Ju Lee from APCC, the lead author of the paper, stated that monitoring and predicting the location of WNPSH, as well as understanding the mechanism and factors that are influencing the movement of WNPSH under global warming, are necessary for predicting and coping with extreme HPT.​​

Dr. Boksoon Myoung’s Research Paper on Occurrence Correlation between Cold Winters Followed by Hot Summers in South Korea Attracts Public Attention.
Dr. Boksoon Myoung from APEC Climate Center (APCC) wrote the research paper entitled"Recent Trend of Cold Winters Followed by Hot Summers in South Korea due to the Combined Effects of the Warm Western Tropical Pacific and North Atlantic in Spring". Her paper, recently published online in Environmental Research Letters, recently attracted the public attention and media.* Paper link : https://iopscience.iop.org/article/10.1088/1748-9326/ac1134Her paper finds a significant negative correlation between the December-February mean surface temperature and the following June-August mean surface temperature in South Korea for the period 1991-2017. This indicates that colder winters tend to precede hotter summers with extreme seasonality, while mild winters generally precede mild summers.This winter-to-summer association can be attributed to persistent atmospheric circulation anomalies on the Eurasian continent during the preceding winter and spring characterized by cyclonic circulations in Europe and East Asia and anti-cyclonic circulation in the Arctic region.These findings are expected to contribute not only to enhance the ability to predict summer temperatures and heat waves in Korea, but also to establish effective heat wave measures in the future. In addition, her study scientifically identified that this extreme climate phenomenon has become serious since 1991 due to climate change. These research results enable us to effectively cope with extreme climate by linking the prediction of heat waves with the occurrence of cold waves in the future.

The APEC Climate Center Held the APCC Working Group Meeting 2021
The APEC Climate Center (APCC) held the virtual APCC Working Group Meeting 2021 on 15 July 2021 with 11 Asia-Pacific Economic Cooperation (APEC) Member Economies.At this meeting, representatives from the National Hydro-Meteorological Services (NHMSs) from APEC member economies shared their current status of climate prediction and services and the status of extreme events in recent years, including communication strategies.Based on this, the meeting participants from the APEC member economies and APCC had the chance to present opinions on the use and improvement of climate prediction and its information provision service, and to discuss the future direction of climate services. The meteorological agencies from 9 APEC member economies delivered presentations on the current status and pending issues of external communication regarding the extreme climate and climate crisis. All participants shared the efforts and cases of each country's meteorological agency to communicate climate information service in various ways, even during the COVID-19 pandemic. By doing so, the meeting participants tried to find ways to effectively monitor and respond to extreme events across the Asia-Pacific region and to produce and utilize the necessary climate prediction information to prepare for these events.The meeting was attended by climate forecasting and service working groups from the National Hydro-Meteorological Services (NHMSs) from 11 APEC member economies including Malaysia, Australia, Indonesia, Japan, New Zealand, Singapore, Philippines, Taiwan, Thailand, Canada, and Korea (Korea Meteorological Administration, KMA).The APEC Climate Center collected opinions from the working group members on the use of APCC's climate prediction and provision services and future areas to improve. Strengthening cooperation with APEC member economies to enhance climate prediction capabilities, will also elevate the climate information user satisfaction in relation to APCC’s extreme climate event monitoring information across the Asia-Pacific region.The APCC Working Group is made up of representatives from the NHMS from all APEC Member Economies, as well as other relevant participating institutions. The Working Group members facilitate the exchange of regional climate information, particularly climate prediction information among the APEC member economies. The group works closely with the APCC Climate Research Department in the improvement of the multi-model ensemble (MME) forecasting system and for the development of new forecast application areas.​

APCC and MET Malaysia Co-hosted the APEC Climate Symposium 2021
The APEC Climate Center (APCC) andMalaysian Meteorological Department (MET Malaysia) virtually co-hosted the APEC Climate Symposium (APCS) 2021 on 13-14 July 2021 with the main theme of ‘Innovations in Climate Communication for Enhancing Human Security to Manage Risks of Climate Extremes’.This virtual event provided a unique opportunity to engage in discussion with experts from governments, academia, private sector, and NGOs on utilizing climate information against the climate crisis and communicating climate information services effectively.During the opening session of APCS 2021, the opening remarks were delivered by Dr. Won Tae Kwon, Executive Director of APCC and Mr. Jailan bin Simon, Director General of Met Malaysia.The APEC Climate Symposium 2021 was composed of 2 panel discussion sessions. The main topic of the first panel discussion, held on 13 July 2021, was ‘Enhancing Climate Crisis Preparedness through Climate Service’. The participants of this session had the opportunity to explore effective ways to use climate information services in the era of climate crisis.The main topic of the second panel discussion session, held on 14 July 2021, was ‘Exploring Innovative Communicating Strategies for Effective Climate Services’. The participants of this session discussed specific methods for enabling climate information to be utilized by various users to respond to climate disasters and extreme climates. In particular, they also explored the strategies and measures for climate communication to reduce the gap between climate information providers and users, and specific roles and efforts needed to facilitate communication of climate information.APCC hosts the APCS annually to facilitate knowledge exchange on the latest climate prediction techniques in the region and beyond. APCS also builds capacity for climate adaptation and provides a venue for interaction amongst the world’s leading scientists, researchers, meteorological services, decision makers, and other stakeholders. Themes related to climate prediction and its applications are developed each year which guide the organized sessions and presentations. ​
