Short Summary

This study assesses the atmospheric water vapour and potential mechanisms in the northern slope of Kunlun Mountains using MERRA-2 data sets, revealing increasing trends in evapotranspiration, precipitation, and atmospheric water resources from 1980 to 2023.

Objective

• Investigate the characteristics of atmospheric water vapour resources in the northern slope of Kunlun Mountains (NKM) and their potential mechanisms.

Study Configuration

• Spatial Scale: Regional scale, focusing on the NKM.
• Temporal Scale: Long-term analysis from 1980 to 2023.

Methodology and Data

• Models used: MERRA-2 reanalysis data sets.
• Data sources: Satellite, observation, and reanalysis datasets (ERA5 and NCEP).

Main Results

• Increasing trends in evapotranspiration (0.51 mm/decade) and precipitation (0.55 mm/decade) from 1980 to 2023 in the NKM.
• Rising atmospheric water resources, consisting of water vapour content (99.65%) and cloud water (0.35%), closely related to perturbed circulations of an anticyclone over the NKM.

Contributions

• Provides a comprehensive understanding of atmospheric water vapour resources in the NKM and their potential mechanisms.
• Offers scientific support for the utilization of these resources, contributing to regional economic development and ecological security.
