“…These contributions should be quantified and recognized as the value of green water to socio-economy, which expands the scope of water management and water security maintenance (Keys et al, 2017;Rockström et al, 2023). Emerging moisture tracking technologies offer feasible ways to quantify green water flow across regions at large scale (Keys et al, 2019;Li et al, Recent studies analyzed green water flows at the national or regional scale to identify the source and sink areas of specific regions, like the Tibetan Plateau (Zhang et al, 2024) and Europe (Pranindita et al, 2022). However, green water flows from different regions are interlinked because different regions could become sources and sinks of each other, especially for large countries like China.…”

Abstract. Green water (terrestrial evapotranspiration), flowing from source regions and precipitates downwind via moisture recycling, generates surface water resources and sustains socio-economy in sink regions. However, unlike blue water, there has been limited assessment of green water flows and their tele-connected effects on socio-economy. This study used the moisture tracking dataset of 2008–2017 to quantify interprovincial green water flows in China and their socio-economic contributions. Results reveal a complex flow network where green water of each province reciprocally exchanges with each other. Despite self-recycling, green water from source provinces mainly forms precipitation in neighboring provinces, with average interprovincial flow directions from west to east and south to north. About 56 % of total green water exported from 31 provinces retains at home and contributes 43 % of precipitation in China. Our assessments show that green water from source provinces embodies substantial socio-economic values for downwind provinces with regionally varying importance. Western provinces are the largest contributors to surface water resources while southwestern and central provinces embody the highest GDP, population, and food production. About 40 % surface water resources, 45 % GDP, 46 % population, and 50 % food production of China are supported by green water from 31 provinces. There is an overall increase in embodied socio-economic value of green water flow from source to sink provinces, suggesting that less developed provinces effectively support the higher socio-economic status of developed provinces through green water supply. The results emphasize the substantial tele-connected socio-economic values of green water and the need to incorporate it for a more comprehensive and effective water resources management.

The storms over the Bay of Bengal (BoB) often combine with the weather systems such as the South Branch Trough (SBT) and the West Pacific Subtropical High (WPSH) to transport plenty of moisture inducing extreme precipitation on the Tibetan Plateau (TP). Determining the fine moisture structures of storms helps understand mechanism of this kind of extreme precipitation. An extreme precipitation occurred on the TP influenced by storm Rashmi (2008). A Lagrangian approach is scrutinized the forward and backward moisture transport trajectories of Rashmi and the TP, respectively. The moisture source of this extreme precipitation is relatively clear, which comes from the collaborative influence of Rashmi with the southwest jet generated by the SBT and the WPSH. Utilizing a three‐dimensional K‐means clustering method devised in this study, the Rashmi's forward trajectories are classified into three categories, the particles ascending with the northward movement of Rashmi (45%), consistently below 1 km (37.5%), and rapidly ascending into the southwest jet stream (17.5%). Notably, 97.5%, 1.2%, and 91% of these categories impact the TP, respectively. The moisture transport structure of storm is verified by backward tracking of moisture over the TP. In addition, the three‐dimensional moisture trajectories classification method is recommended when trajectories suffer rapid altitude changes.
