Sea spray effects on typhoon prediction in the Yellow and East China Seas: Case studies using a coupled atmosphere-ocean-wave model for Lingling (2019) and Maysak (2020)
This study investigates the impact of sea spray parameterization on typhoon prediction in the Yellow and East China Seas (YECS) region. Using an air-sea-wave coupled model, we evaluate changes due to sea spray effects in the simulated intensity and structure of Typhoons Lingling (2019) and Maysak (2020). Enabling sea spray effect enhances surface turbulent heat fluxes considerably around the typhoon centers (74% increase for Lingling, 92% for May…
Siberian heat extremes caused by Eurasian atmospheric teleconnections and amplified by local land surface conditions
This study aims to examine the mechanisms that drive extreme heat events in Siberia during boreal spring. The results from this study suggest that the upper-level atmospheric waves across Eurasia induced by the warm sea surface temperature (SST) in the eastern North Atlantic and large snow melting in southern Siberia are responsible for a large temperature increase in Siberia. These suggested mechanisms are examined by both observed data analysis…
Causes on the 2018 record-breaking heatwave in South Korea: Compound impacts from recurrent large-scale atmospheric teleconnections
This study analyzed the causes of the extreme heatwave in East Asia in 2018, which brought a record-breaking event in South Korea in terms of the number of hot days and the intensity in history. Long-lasting atmospheric patterns were observed during the 2018 heatwave, and the patterns were similar to those known as the Pacific–Japan (PJ), circum-global teleconnection (CGT), and Arctic Oscillation (AO) patterns identified in a previous study. In 2…
The difference in the uncertainty sources between future projections of mean and extreme precipitation over East Asia
As the incidence of extreme precipitation events attributable to global climate change increases, providing policymakers with accurate model predictions is of the utmost importance. However, model projections have inherent uncertainties. The present study attempted to distinguish the sources of the uncertainty of the mean and extreme precipitation projections in the East Asia region using the mean boreal summer precipitation, simple precipitation…
Unveiling the pivotal influence of sea spray heat fluxes on hurricane rapid intensification
Predicting rapid hurricane intensification remains a challenge, partially due to neglected factors like sea spray-mediated heat flux. To shed light on the specific roles of spray-mediated sensible and latent heat fluxes, we conducted sensitivity experiments with heat flux parameterizations. Our results demonstrate that the inclusion and variation of the spray-mediated sensible heat significantly reduce model errors when compared against dropsonde…
Future changes in extreme heatwaves in terms of intensity and duration over the Cordex-East Asia Phase Two domain using multi-GCM and multi-RCM chains
An extreme heatwave, in terms of intensity and duration, is projected to occur at the end of the 21st century (2071–2100) over the whole of East Asia. The projection is calculated using daily maximum temperature data of 25 km horizontal resolution produced by 12 general circulation model-regional climate model chains participating in the CORDEX-East Asia Phase 2 project. An ‘extreme’ heatwave is defined as one in which the heatwave magnitude (HWM…
Uncertainty analysis of future summer monsoon duration and area over East Asia using a multi-GCM/multi-RCM ensemble
This study examines the spatiotemporal characteristics of the summer monsoon rainy season over East Asia using six regional climate models (RCMs) participating in the Coordinated Regional Domain Experiment (CORDEX) East Asia Phase II project. The framework combining multiple global climate models (GCMs) with multiple RCMs produces a larger spread in summer monsoon characteristics than driving GCMs only, enabling a better quantification of uncerta…
