Summary: Studies on precipitation changes in Central Asia show an increasing trend in total and extreme precipitation indices, especially in the wetter sub-regions. Model simulations suggest a robust increase in total precipitation, extreme precipitation, and consecutive dry days in the region under different climate scenarios.

Summary: This study tests the application of a rare event simulation (RES) algorithm to speed up the sampling of extreme winter rainfall over Europe in a climate model. The algorithm effectively reduces the computational effort required to estimate probabilities of extreme events, demonstrating the potential of RES for simulating seasonal precipitation extremes.

Summary: On May 7, 2017, two precipitation centers were observed over the urban edge of the Pearl River Delta in South China, generated by meso-beta-scale convective systems. The study found that most convection in the two precipitation centers was active below the freezing level, indicating warm rain processes dominated extreme rainfall production, and discrepancies in convective and precipitation features existed between the two centers. This suggests the possibility of developing a more suitable Z-R relationship for extreme precipitation events in operational now casting over South China.

Summary: This study analyzed the response characteristics of extreme climate to global climate change over arid regions, using temperature and precipitation data from meteorological stations in Xinjiang, China. The results showed a decreasing trend in extreme low temperature indices and an increasing trend in extreme high temperature indices. The extreme precipitation indices, except for consecutive dry days, exhibited increasing trends, with heavy precipitation concentrated in the Ili River and Altai Mountains in northern Xinjiang.

Summary: The study finds a strong association between extreme precipitation events and circulation patterns in the central-eastern China region. Based on data classification and comparison, it is found that circulation patterns have become more synchronized with extreme precipitation events since 1990, resulting in an increase in the frequency of extreme precipitation.

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: The study reveals a close relationship between the emergence of extreme precipitation events and moisture supply from the Atlantic or Mediterranean, as well as the ascent of moist air. By classifying EPEs into three different moisture flux variants, the research found distinct seasonal and spatial patterns in extreme precipitation distribution, indicating a direct link between anomalies in moisture flux and precipitation extremes, particularly in the case of events with dominating moisture flux from the north.

Summary: This research studied the characteristics and synoptic patterns of extreme precipitation events over the central and eastern areas of the Tibetan Plateau from 1981 to 2016, showing that the largest amount of extreme precipitation occurs in the southern and eastern regions with a quasi-biweekly oscillation in frequency. A total of 33 regional extreme precipitation events were identified, classified into plateau trough type, plateau shear line type, and plateau vortex type based on influence systems.

Summary: This study compares the representation of extreme precipitation events between a 12 km resolution RCM and a 2.2 km resolution CPM. The comparison reveals large differences in the location and movement patterns of extreme event tracks between the CPM and RCM, indicating different event types may be sampled in the two models, with differences extending to much larger scales. The study suggests that extreme precipitation projections from traditional coarse resolution RCMs need to be used with caution, due to the possible influence of grid-point storms.

Summary: Timely and systematic collection of landslide information is crucial in understanding landslide trends in response to climate change. A severe rainfall event in central Italy triggered 1687 landslides, causing widespread flash floods and affecting the road network. The collected data can be used for comparison with past landslides, validation of landslide susceptibility models, and understanding the interaction between landslides and structures/infrastructures.

Summary: Large solar coronal mass ejections can pose a threat to near-Earth space, damaging communications and energy networks and posing risks to life and the environment. Based on data analysis, the July 2012 solar coronal mass ejection had significant impacts on atmospheric ozone and similar extreme events could result in long-term ozone reduction and the expansion and deepening of the Antarctic ozone hole.

Summary: This study investigates the sub-seasonal drivers of extreme precipitation events (EPE) in the Central Sahel. A statistical approach is used to analyze the average EPE. It is found that EPEs occur within a large-scale moist anomaly, an upper-level divergence, and at shorter scales an intense vortex. These features are provided by multiple tropical waves, especially an Equatorial Rossby wave (ER) and an African Easterly Wave (AEW). Statistics show that the combination of AEW with ER and/or Kelvin wave increases the probability of EPE. Monitoring these tropical wave combinations could improve EPE forecasts.
