Summary: The rainbands in the East Asian summer monsoon migrate northward from spring to summer and are influenced by extratropical northerly winds and persistent lower-tropospheric southerly winds. The background northerlies may originate from the interaction between the jet stream and the Tibetan Plateau.

Summary: The study investigates the relationship between the Atlantic multidecadal variability (AMV) and atmospheric heat source over the Tibetan Plateau (TPHS), as well as their combined impact on the East Asian summer rainfall (EASR). Results show that the AMV has a remote effect on the EASR through an atmospheric teleconnection, and the TP plays a enhancing role in this effect. The TP amplifies the impact of the AMV on the EASR through the orographic effect and further strengthens the summer monsoon and the East Asian tripole rainfall pattern.

Summary: Recent studies have highlighted a significant change in the impact of summer snow cover over the western Tibetan Plateau on East Asian summer precipitation. Prior to the early 2000's, higher snow cover correlated with positive precipitation anomalies in Southeast China, but post-2000, reductions in snow cover led to abnormal precipitation in Northern China and Northeast Asia. The shift in the influence of Tibetan Plateau snow is linked to changes in atmospheric circulation patterns with contrasting wind anomalies observed before and after the early 2000's.

Summary: Recent studies show that the position of the Tibetan Plateau plays a crucial role in determining the precipitation of the East Asian summer monsoon. The strength of monsoon aspects is entirely determined by the location of the plateau, with north-south displacement affecting precipitation intensity significantly.

Summary: Heavy summer precipitation over the southern slope of the Tibetan Plateau has significant impacts on water resources and hydrological disasters in South Asia. The trends of this precipitation have shown an increase from 1979 to 1996, followed by a decrease from 1996 to 2022, which are not well understood. This study suggests that stratospheric ozone plays a significant role in the long-term trends of summer precipitation in this region by affecting deep convection and precipitation over the southern slope of the Tibetan Plateau. It is crucial for future water resource management in South Asia to consider the potential reduction in summer precipitation due to ozone recovery.

Summary: The study reveals that summer precipitation in the southern Tibetan Plateau is significantly influenced by precipitation intensity, with a strong correlation between precipitation amounts and PGs. The precipitation characteristics between different catchments show consistency, but vary greatly under different precipitation intensities.

Summary: Understanding the evolution of the East Asian Summer Monsoon (EASM) at different time scales is important for revealing the interactions between the hydrosphere, land, oceans, and atmosphere. By studying the late Miocene period, researchers have reconstructed the EASM precipitation and found that it is influenced by global climate and the uplift of the Tibetan Plateau. Additionally, on orbital time scales, the eccentricity periodicity plays a dominant role in the EASM precipitation cycles.

Summary: This study finds that the persistent suppression of transient eddies by the Tibetan Plateau weakens the East Asian westerly jet stream, leading to changes in precipitation patterns over East Asia, particularly in early summer. This suppression causes a southward shift of the East Asian rain belt, promoting increased rainfall in the southern region.

Summary: The total column ozone (TCO) over the Tibetan Plateau (TP) is lower than other regions at the same latitude, especially in summer, forming the TP ozone valley. CMIP6 models simulate the TCO and ozone valley changes well, with the coupled chemical-radiative-dynamical processes playing a key role in the simulation of the TP ozone valley. Most CMIP6 models predict that the TP ozone valley will deepen in the future during summer months.

Summary: This paper investigates the formation mechanism of the ozone valley in the upper stratosphere over the Tibetan Plateau. The results suggest that the different distributions of NO2 during the day and night, as well as the temperature difference between the Tibetan Plateau and other regions at the same latitude, may contribute to the diurnal and nighttime variation of the ozone valley.

Summary: The study reveals that ENSO significantly influences summer rainfall over the southwestern Tibetan Plateau by impacting both vertical motion and moisture deficit. Additionally, the strengthening of the India-Burma monsoon trough during El Nino developing summer contributes to the deficit of rainfall in the southwestern region.

Summary: The study shows a significant interannual relationship between the meridional displacements of the upper-tropospheric westerly jet streams over West Asia and East Asia. The Silk Road pattern and precipitation anomalies in the tropical region are important factors affecting this relationship. Enhanced or suppressed tropical precipitation can induce a northward or southward displacement of the jet stream, contributing to the in-phase relationship between West Asia and East Asia.

Summary: This study explores the influences of interannual surface potential vorticity forcing over the Tibetan Plateau on East Asian summer rainfall and upper-level circulation. The results indicate that this surface potential vorticity forcing is closely related to the EASR and associated circulations. The positive phase of the potential vorticity leads to increased rainfall in certain regions, while the negative phase leads to decreased rainfall. Furthermore, the mechanism behind this influence is proposed, involving the stimulation of upward motion and anomalous cyclone by the positive phase of the potential vorticity.

Summary: The study on precipitation trends in the Tibetan Plateau reveals significant interdecadal changes in the past few decades, which are closely related to the changes in the area of TP lakes. The southern TP has experienced an increasing-then-decreasing trend in precipitation, while the northern TP has shown a decreasing-then-increasing trend. The changes in the southern TP are mainly attributed to the weakening sensible heat source, while the northern TP is influenced by the cold interdecadal Pacific oscillation (IPO) and warm Atlantic multidecadal oscillation (AMO).

Summary: Rapid warming over the Tibetan Plateau has led to an increasing trend in atmospheric water vapor content, particularly in the western region. The study shows that both internal and external cycles contribute to the wetting phenomenon, with the western TP experiencing increased PRE, evaporation, and moisture convergence. Additionally, the atmospheric heating source is also rising in the western TP, leading to a shift in moisture transportation and the formation of a positive feedback loop.
