摘要

在这项工作中,我们利用卫星数据和云解析模式模拟,记录了季风前和季风季节印度地区和周围海洋的云水成物特征。我们已经确定了水成物的时空变异性,并借助大气的物理性质对其进行了解释。此外,我们还对WRF-Chem进行了云分辨模拟,以了解观测到的云液态水和降雨的变化。我们还发现,在气溶胶高负荷和低负荷期间,云性质的变化导致了印度夏季风的季节内振荡特征的变化。

Aerosols-cloud interaction during active-break cycle of Indian summer monsoon from satellite observations and cloud resolving model simulations
In this work, we have documented the characteristics of cloud hydrometeors over Indian region and surrounding oceans during pre-monsoon and monsoon seasons, using satellite data and cloud resolving model simulations. We have identified spatio-temporal variability of hydrometeors and explained them with the help of physical properties of the atmosphere. Further, we have performed cloud-resolving simulations of the WRF-Chem to understand the observed variability of cloud liquid water and rainfall. We have also found changes in cloud properties during high and low aerosol loading, leading to changes in the characteristics of intraseasonal oscillation of Indian summer monsoon.
