Summary: Cold fronts are an important weather system that produces precipitation in East Asia. This study proposes an objective identification method for cold-front precipitation and investigates the climatological characteristics and trends of cold-front precipitation over East Asia in the past three decades. The results show that cold fronts significantly contribute to winter precipitation in East Asia and have a considerable impact on the trend of total precipitation.

Summary: The Northern Hemisphere often experiences cold air outbreaks and heavy snowfalls during La Nina winters. However, the climate predictions for the 2022/23 winter suggest that abnormal warming may cover most parts of Europe, despite the cooling effects of La Nina. On the other hand, mid-latitude Asia is expected to experience frequent cold conditions due to the synergistic effect of a warm Arctic and a cold tropical Pacific. However, the future climate evolution in the 2022/23 winter is still uncertain due to unpredictable internal atmospheric variability.

Summary: This study examines the drivers behind the increasing trend in the Genesis Potential Index (GPI) of tropical cyclones in the Arabian Sea during the post-monsoon season. The study finds that increased atmospheric moisture loading, ocean heat content, and reduced vertical wind shear are the main factors contributing to the intensification of cyclone GPI. The study also identifies the influence of changes in the northern high-latitude climate on the cyclone genesis through the alteration of the subtropical jet and upper atmospheric circulation.

Summary: Psychological impact plays a significant role in adaptive thermal comfort models, with perceived control being an important factor. Studies in China's Hot Summer and Cold Winter zone found that different heating systems can affect residents' thermal neutral temperatures, and perceived control can improve thermal comfort.

Summary: The design parameters of a building envelope, such as windows, apertures, shading, and materials, have a significant impact on a building's performance. However, few studies have simultaneously optimized these parameters to find trade-off solutions between energy consumption, indoor daylighting, and thermal comfort. This study presents a multi-objective optimization framework that evaluates various design and performance parameters to investigate their interactive relationships. The results help architects in the design, refurbishment, and renovation of building envelopes by providing optimal solutions for energy performance, thermal comfort, and visual comfort.

Summary: An enhanced Warm Arctic-Cold Eurasia (WACE) pattern has been observed in recent winters in the Northern Hemisphere, but there are divergent results between model and observational studies. This study evaluates the performance of 39 climate models and finds that the multimodel ensemble can better simulate the WACE pattern compared to most single models. The ability of the models to simulate the range and intensity of the warm anomaly in the Barents Sea-Kara seas region is a key factor for accurately simulating the WACE pattern.

Summary: The study revealed that during winter, residents' thermal sensations in Beijing, Xi'an, and Hami were primarily affected by air temperature and globe temperature. Xi'an residents had the highest neutral Universal Thermal Climate Index (NUTCI), while Hami residents had the lowest. Residents in Beijing and Hami preferred lower wind speeds, while residents in Xi'an and Hami preferred higher relative humidity.

Summary: The warm Arctic-cold Eurasia (WACE) pattern is a significant feature of Eurasian climate variations in winter, which is related to sea ice loss in the Barents-Kara (BK) seas. A statistical decomposition approach reveals that an anticyclonic circulation anomaly over subarctic Eurasia forces the WACE anomalies, peaking 3 days before BK sea ice loss. The weakened moisture transport associated with enhanced BK downstream ridge and East Asian trough due to BK sea ice loss results in mature East Asian cooling about 15 days later. BK sea ice loss contributes to 65% and 81% of the WACE-related East Asian cooling and Arctic warming, respectively, at interannual timescale.

Summary: This paper explores the physical cause of the decadal variability of the warm Arctic-cold Eurasia (WACE) pattern observed in recent decades. The study finds that the phases of the Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) mediate the decadal variability of the WACE pattern. The study also highlights the influence of PDO and AMO on the meridional structure of the WACE pattern, leading to different spatial distributions of warm and cold anomalies.

Summary: This study focuses on the outdoor thermal comfort in factory areas and investigates the effect of different built environments on workers' thermal sensations. Through field measurements and questionnaire surveys, the research establishes the outdoor thermal benchmark suitable for factory areas and identifies the factors influencing thermal comfort. The findings could provide theoretical guidelines for the design of factory areas.

Summary: A series of extreme cold events occurred across Eurasia and North America during winter 2020/21. Reduced Arctic sea ice, La Nina, and a sudden stratospheric warming were identified as factors contributing to the extreme cold wave in February 2021. The Arctic and Pacific Ocean surface conditions in winter 2020/21 increased the probability of cold days by approximately 17%-43%.

Summary: Individual differences in thermal sensation are influenced by age, gender, and BMI. Among these factors, age has the greatest impact, followed by gender, and then BMI. The results showed that the neutral temperature increases with age, females have a higher neutral temperature compared to males, and an increase in BMI leads to an increase in neutral temperature.

Summary: This study demonstrates that the loss of autumn sea ice in the Kara-East Siberian Sea (KESS) intensifies the Eurasian cold spells in winter. The weakening of the polar vortex and the enhancement of Ural blocking contribute to the prolonged and intensified cold events.

Summary: Eurasia and North America experienced a strong subseasonal swing of surface air temperature extremes in the 2020/21 winter. This swing had severe impacts on human activities and the global economy. The alternating extremes were caused by annual cycle anomalies of surface air temperature and the phase transition of the North-Pacific-Oscillation-like Rossby wave.

Summary: Long-lasting regional extreme low-temperature events have severe impacts on human societies, with decreasing frequency but increasing intensity and affected area. Winter long-lasting RELTEs in Eurasia exhibit distinct trends under various climate backgrounds, possibly showing a recovery in the slowdown period of global warming.
