In order to deeply explore the deformation mechanism and response mechanism of the retaining structure and the surrounding soil during the excavation process of the subway in the soft soil area of Suzhou, the construction project of the foundation pit of 8 metro stations in the area was selected, the foundation pit construction projects of 8 metro stations in the area was selected, and the evolution of underground continuous wall displacement and surface settlement was researched during excavation by arranging monitoring points. The results show that, the horizontal displacement curve in the depth direction of diaphragm wall is similar to the “bow” type during excavation, and the trend of “bow” type increases with the increase of excavation depth. The maximum horizontal displacement of the whole foundation pit is located at the midpoint of the long side, and it slowly moves down during excavation, and finally tends to be stable. The maximum horizontal displacement is about 0.6-0.8 of the excavation depth, and the maximum horizontal displacement is 0.1%-0.3% H. During the excavation of foundation pit, the surface settlement increases, and the overall deformation is “concave”, with the maximum value of 0.014%~0.326% of the excavation depth. The maximum horizontal wall displacement and maximum surface settlement are linearly distributed with the excavation depth of the foundation pit, and the maximum surface settlement is also positively correlated with the maximum horizontal wall displacement. The maximum horizontal displacement of the wall is 0.54~1.14 times of the maximum surface settlement. The influence of the horizontal wall insertion on the horizontal displacement of the maximum wall is significant, and the influence on the maximum surface settlement is not strong.

Haoran Jiang, Quda Zhaxi, Bo Yu, Jie Zeng, Junxiang Jin — Thu, 02 Jan 2025 15:04:36 +0800

This study investigates the influence of sea surface temperature (SST) anomalies in the Indian Ocean Warm Pool, represented by the Indian Ocean Warm Pool Strength (IOWPS) index, on extreme precipitation (RX1day) over the Tibetan Plateau. Using daily precipitation data from the Climate Prediction Center and SST data from the National Climate Center, we assess the relationship between IOWPS and extreme precipitation from 1994 to 2023. Results show a strong positive correlation (r = 0.610) between IOWPS and regionally averaged RX1day. Spatial analysis indicates that the strongest positive correlations are located in the southeastern and southern parts of the plateau, where the South Asian monsoon, modulated by the Indian Ocean warm pool, brings substantial moisture. The findings highlight the significant role of the Indian Ocean warm pool in driving extreme precipitation, particularly through monsoonal moisture transport. This research underscores the importance of understanding ocean-atmosphere interactions for predicting extreme precipitation events in this climate-sensitive region.

Climatologies of mean wind in the Tibetan Plateau as revealed from a state-of-the-art global atmospheric reanalysis

Yongbin Li, Fangyong Xiao, Chao Liu, Gui La, Ciren Pingcuo — Thu, 02 Jan 2025 15:04:40 +0800

This study investigates the mean wind speed characteristics over the Tibetan Plateau using ERA5 reanalysis data from 2014 to 2023. The analysis reveals significant spatial and seasonal variability in wind speeds, driven by the interaction of large-scale atmospheric circulations, particularly the westerly jet stream and the Asian summer monsoon, with the plateau’s complex topography. The highest mean wind speeds, exceeding 4.5 m/s, are observed in the northern and central plateau, where the westerlies dominate, especially during the winter and early spring. In contrast, the southern and southwestern regions, shielded by the Himalayan range, experience much lower wind speeds, typically below 2.0 m/s, largely due to the monsoon’s influence. These seasonal variations highlight the importance of understanding wind dynamics for renewable energy development and regional climate modeling. The study provides valuable insights for optimizing wind power generation and improving climate simulations in this key region.

Analysis of extreme wind speed characteristics over the tibetan plateau based on ERA5 reanalysis data

Huabo Pan, Feng Li, Chao Yang, Dafei Wang, Weiwei Zhao — Thu, 02 Jan 2025 15:04:42 +0800

This study analyzes the extreme wind speed characteristics over the Tibetan Plateau using ERA5 reanalysis data from 2014 to 2023. The spatial distribution of extreme wind speeds reveals that the northern and central regions experience the highest wind speeds, with maximum values exceeding 15 m/s, driven primarily by the influence of the westerly jet stream. In contrast, the southern plateau, particularly near the Himalayas, shows much lower extreme wind speeds, typically below 5 m/s, due to the Himalayan barrier and the stabilizing effect of the Asian summer monsoon. Extreme wind speeds exhibit strong seasonal variability, peaking in winter and early spring when the westerlies are strongest, and reaching their lowest values in summer due to the monsoon. These findings offer important insights into the risks associated with extreme wind events and their potential impact on infrastructure, renewable energy development, and climate resilience strategies in the region.
