英文简介By altering the moisture and energy exchanges between land surface and atmosphere, land use plays an important role in affecting the dynamical process of PBL, thus modulating the formation of cloud. Many studies have been carried out to investigate the relationship between the land use change and cloud properties, while further efforts are required to understand the feedback and mechanism. This project aims to study the impact of different types of land use on cloud properties over arid/semiarid Hetao region. With satellite datasets, the relationship between the properties of cloud with heterogeneous land surface (desert, grass and crop) over Hetao region will be analyzed, with the purpose to understand how the land use change affects the cloud formations. Then numerical experiments will be designed and carried out by high resolution regional climate model to simulate the mechanisms of the influence of the land use change on the cloud properties. Using combination of satellite observation and high-resolution model simulation, the impacts of thermal-dynamical processes on cloud formation and the interactions with large scale monsoon circulation are analyzed over Hetao region. The implement of this project will further our understanding on the mechanism of cloud formation and evolution over the climatically vulnerable regions such as Hetao region. It will contribute to the impact studies of land use changes on the regional climate over arid/semi-arid region as well.
