Summary: This study investigated the variability of extreme precipitation in eastern central Asia during summer and its corresponding mechanisms from a multiscale synergy perspective, finding an increasing trend in extreme precipitation since 2000, likely due to high-latitude North Atlantic SST anomalies. Various factors, such as cyclonic anomalies, quasi-stationary wave trains, and synoptic transient wave trains, contributed to the increase in extreme precipitation in eastern central Asia.

Summary: This study aimed to explore the changing characteristics and underlying mechanisms of extreme hot-humid events over eastern China in recent decades. Results showed an increasing trend in these events, with strong interannual variability. The key factors linked to these variations were identified as anomalies in sea surface temperatures over the northwest Pacific and western tropical Pacific, as well as Arctic sea ice concentration anomalies in May.

Summary: The variation of the tropical rain belt is largely driven by equatorial precipitation inhibition. The tropical modality is a fundamental characteristic of tropical climate, which is associated with the width of the rain belt and the meridional overturning circulation. Low modality regions exhibit monsoonal seasonal variations, while high modality regions have three independent seasonal modes of variation.

Summary: This study investigates the synoptic atmospheric patterns responsible for regional extreme high-temperature events in northern Asia. Three subregions in northern Asia are identified: western, central, and southeastern. Six synoptic circulation patterns are categorized, which influence the occurrence of extreme high-temperature events through different radiation and advection processes. Six wave trains originating from the North Atlantic Ocean and Europe serve as precursors for these synoptic circulation patterns, affecting the extreme high-temperature events in northern Asia.

Summary: Investigation of atmospheric circulation patterns causing extreme precipitation events in South Eastern Siberia (SES) and Mongolia from 1982-2019 revealed increased instability within the precipitation area and enhanced moisture transport by the East Asian summer monsoon. Positive and negative anomalies of potential vorticity were amplified in subtropical and mid-latitude regions, respectively, around Lake Baikal. Extreme precipitation events were characterized by cyclonic wave breaking and cutoff low. The study suggests a shift of extreme precipitation to the northwest, possibly due to changes in wave propagation.

Summary: Extreme precipitation events in Norway are often linked to atmospheric rivers, with the coastal regions experiencing the highest association with AR. During AR events, Norway sees stronger winds and a temperature increase at 850 hPa. Cyclones are commonly found near AR landfall points, with precipitation peaking ahead of the arrival of the atmospheric river.

Summary: The study examined the spatial and temporal variation of extremal temperature and precipitation indices in mainland China from 1960 to 2016. It found consistent warming trends in temperature indices, with increases in warm days and nights and decreases in cold days and nights. Large-scale atmospheric circulation indices were identified as significant factors influencing extreme temperature and precipitation events in mainland China.

Summary: Recent advancements in climate modeling have improved the horizontal resolution in different components of the simulating system. This study focuses on the potential improvements in representing extreme events of high temperature and precipitation using high-resolution versions of the CMCC-CM2 model. The results show that the high-resolution model performs better in representing both mean and extreme climate conditions compared to the standard resolution model. However, the adoption of a higher horizontal resolution does not improve extreme precipitation events.

Summary: This study investigates the moisture sources of extreme precipitation events in arid Central Asia (ACA), showing that both Northern and Southern ACA are influenced by multiple sources of water vapor, with anomalous moisture from the North Atlantic and Arctic Ocean playing a key role in precipitation development. Additionally, atmospheric pressure anomalies are also crucial in determining precipitation patterns in ACA.

Summary: The study systematically identified and quantitatively analyzed synoptic patterns associated with extreme summer precipitation events over East China during 1961-2018, revealing that the events are mainly driven by the East Asian summer monsoon, Meiyu front, landfalling tropical cyclones, and low-pressure vortices. Most sub-regions have experienced increasing trends of extreme rainfall events in the past six decades, with comparable contributions from the two main drivers, while the North China Plain has seen a decreasing trend caused by low-level southeasterly winds.

Summary: Focusing on major cities in southeast Australia, the study aims to distinguish between heavy rainfall events (HREs) and extreme rainfall events (EREs) based on environmental factors, finding that HREs are associated with specific circulation patterns and moisture transport, while EREs show amplified upper-level troughs and stronger vertical motion.

Summary: This study analyzed the spatiotemporal variability of extreme precipitation events (EPE) in China's Loess Plateau and explored the combined effects of multiple factors on EPE. The results showed evident spatial gradients in EPE indices, with wet EPE increasing in the north and the southernmost areas and decreasing in the middle-south areas. Temperature had a greater correlation with the duration of EPE in summer and the intensity and frequency of EPE in winter. The El Nino-Southern Oscillation (ENSO), Pacific North American teleconnection pattern (PNA), ENSO-Arctic Oscillation (AO), and ENSO-AO-PNA were identified as the main factors influencing EPE.

Summary: The study identified two types of atmospheric circulation anomalies that are favorable for extreme precipitation events over southwest China during the rainy seasons. Rossby wave trains from the Northeast Atlantic and the Ural Mountains are critical precursors of the extreme precipitation events. The low-latitude atmospheric circulation anomalies mainly determine the spatial differences and the extremeness of the events.

Summary: The study evaluated the accuracy of global climate models in predicting changes in precipitation extremes under current climate conditions, with most models performing well in this aspect. These models passed two key tests in current climate supporting the use of fractional measures to evaluate future changes in the probability of precipitation extremes.

Summary: A process-oriented diagnostic (POD) is introduced to measure the thermodynamic sensitivity of convection in climate models based on the observed tropical precipitation-buoyancy relationship. The study diagnosed 24 coupled model inter-comparison project phase six (CMIP6) models and found that half of them exhibited sensitivity close to observed, while six models were excessively sensitive.

Summary: General Circulation Models (GCMs) have difficulty in accurately modeling the diurnal cycle of precipitation, particularly in representing the interactions between convection and environmental conditions. Unified convection schemes improve the simulation of precipitation onset time, while the performance of models in capturing deep convection influences accuracy. Detecting elevated convection is crucial for simulating nocturnal precipitation, highlighting the importance of model capability in this aspect.

Summary: This review examines the relationship between precipitation and its thermodynamic environment, specifically water vapor and temperature, and the implications for extreme precipitation changes in a warmer climate. It discusses empirical relationships, changes in precipitation extremes under warming scenarios, and fundamental processes that influence precipitation distributions. The findings suggest that while water vapor increases are governed by temperature, precipitation extreme changes are more complex and can increase rapidly, particularly in the tropics. Integrating different research threads and developing a comprehensive explanation of precipitation probability distribution could advance the understanding in this field.

Summary: A set of diagnostics is used to assess the behavior of the Coupled Model Intercomparison Project (CMIP6) models with respect to precipitation. The models show significant errors in the relationship between precipitation and column water vapor (CWV). Models also exhibit biases in column relative humidity (CRH) statistics, with compensating biases often occurring.
