Summary: This study investigates the impact of Tibetan Plateau vortex (TPV) on extreme precipitation events (EPEs) using TPV and precipitation datasets. The results show that TPV has a significant positive contribution to EPEs. EPEs tend to occur near the center and the southeastern quadrant of TPV. The structure and circulation of TPVs associated with EPEs are significantly different from those without EPEs.

Summary: In this study, the characteristics of large-scale thermodynamic anomalies prior to extreme precipitation events over the Southeastern edge of the Tibetan Plateau (SETP) were analyzed. The results showed that summer extreme events in SETP were influenced by the strengthened Southern Asia high (SAH), the westward-extended Western Pacific subtropical high (WPSH), and an intensified eastern Asia trough. An analogue of low-level vortex embedded in the background large-scale circulations developed at least 4 days prior to extreme events. These anomalies created a favorable environment for precipitation extremes in the SETP region.

Summary: Previous studies have shown that the South Asia monsoon contributes most moisture to the southern Tibetan Plateau, while the westerlies supply moisture to the Northern Tibetan Plateau. However, the sources of moisture for extreme precipitation events were unclear. In this study, external moisture sources were tracked for extreme precipitation events in the Northern Tibetan Plateau from 2010 to 2018. It was found that the South Asia monsoon is the main source of external moisture, except for the easternmost subregion where East Asia contributes the most. The westerlies are the second source of moisture for the western Northern Tibetan Plateau. Additionally, more than 40% of extreme precipitation events in the Northern Tibetan Plateau occur under the interaction of weak westerlies and enhanced South Asia monsoon, and these events have a longer duration.

Summary: The Tibetan Plateau vortices are the major precipitation-producing weather systems on the plateau, with a more significant impact in the warm season but also important in certain regions during the cold season. The interannual variation of vortices and associated precipitation is mainly determined by the number of vortices, while the heating anomaly caused by the Tibetan Plateau thermodynamic effect is also a significant factor.

Summary: Glacier mass loss in the southeastern Tibetan Plateau has accelerated due to increased warming, with the majority of the loss occurring during the monsoon months. Changes in precipitation amount and ratio have played a significant role in the mass loss, with increased solid precipitation in spring mitigating the loss. However, prolonged exposure to warmer temperatures has unsustainably intensified ice melt and catchment discharge, raising concerns for long-term water supply and hazards in the region.

Summary: This study examines the impacts of wintertime western disturbances (WDs) on precipitation over the southeastern Tibetan Plateau (SETP). It finds that WDs, accompanied by warm temperature anomalies and cold temperature decreases, contribute to wintertime precipitation over the SETP. The intensity of WD-induced precipitation is mainly influenced by WD strength and moist static energy variations, while the size and latitudinal position of the WD play minor roles.

Summary: In this paper, the Holocene record of extreme flood events in the upper Minjiang River valley of the eastern Tibetan Plateau, China is analyzed. The study identifies eight palaeoflood slackwater deposits and dates them to between 6.0 ± 0.9 ka and 4.6 ± 0.9 ka. These palaeoflood events are consistent with the mid-Holocene flood events in the mainstream of the Yangtze River and are influenced by ENSO activity and monsoon climate variability. The findings are important for improving regional flood records and developing risk analysis for rare flood events.

Summary: The study examined the temporal and spatial characteristics of persistent extreme heat events (PEHEs) in eastern China during the period of 1961-2018. It found that in terms of spatial distribution, North China is dominated by multi-frequency and short-duration EHEs, while South China experiences PEHEs mostly in July and August. The frequency and duration of PEHEs in North China have increased since the 1990s, showing a response to global warming.

Summary: In an urban agglomeration in the tropics, Singapore, future global warming is predicted to increase the frequency and intensity of extreme precipitation events. The intensification of extreme precipitation can reach maximum rates, implying that extreme events will become more extreme. However, the increase in intensity is less for moderate and light precipitation. Furthermore, global warming dampens the urban effect on extreme precipitation events.

Summary: The present study emphasizes the role of high-resolution land data assimilation in improving the prediction of radiation fog and near-surface meteorological variables. The performance of the Weather Research and Forecasting (WRF) model coupled with the High-Resolution Land Data Assimilation System (HRLDAS) is evaluated for a dense fog event in Delhi, India. The study finds that the combination of HRLDAS and Pleim-Xiu land-surface parameterizations significantly improves the accuracy of predicting micro-meteorological variables and Turbulent Kinetic Energy (TKE) during the fog event.

Summary: This study investigates the response of diurnal temperature range (DTR) to future global warming using a high-resolution climate model. The results demonstrate that global warming will lead to a faster increase in minimum temperature (T-min) compared to maximum temperature (T-max), resulting in a reduction in DTR.

Summary: This study develops a general method to evaluate the contributions of localized urbanization and global climate change to long-term urban land surface temperature change. The method is applied to Lagos as an example, and the results show that both localized urbanization and global warming contribute to the increase in urban land surface temperature, with daytime temperature increasing the most and urbanization being responsible for a significant portion of urban warming in Lagos.

Summary: This study investigates the change of hourly extreme precipitation in Tokyo, Japan under warmer climate regimes. The results show a substantial enhancement of local hourly precipitation in terms of both frequency and intensity. The intensification of extreme precipitation is attributed to the convective inhibition enhancement caused by global warming. The study highlights the geographic diversity in the response of precipitation to global warming.

Summary: This study examines historical changes and possible future projections of temperature extremes in China using observations and multiple models. The observations show that temperature extremes are primarily driven by changing mean climate, but natural variability also plays a significant role depending on the variability index. The models simulate warm extremes well but underestimate the spatial and temporal trends of cold extremes in China. The CMIP6 models show higher skill in simulating temperature extremes and indicate a continued increase in warm extremes in the north and cold extremes in most parts of China in the future.

Summary: Detailed urban information, such as LULC, AH, and UCP, significantly influence meteorological field simulations, particularly when using the WRF model coupled with the SLUCM. This study develops high-resolution datasets for Nanjing, China, and conducts numerical experiments to evaluate the impacts of urban parameters on the thermal environment. Results show that LULC change affects various factors, including temperature, wind speed, and heat flux, leading to urban warming. UCP and AH also contribute to the increase in temperature and other thermal effects.

Summary: Secondary organic aerosol (SOA) formed from vehicle exhaust is a significant contributor to urban particulate matter in the atmosphere. However, there are uncertainties in the simulation of SOA by air quality models due to differences in SOA formation between vehicle types, exhaust aftertreatment devices, and oxidation conditions. This study conducted smog chamber experiments to investigate the formation of SOA from different vehicles under different conditions. The results showed that there are differences in the formation of SOA and its precursors under different conditions, highlighting the need for further examination of the characteristics of SOA.
