Water vapour transport through tropical tropopause layer and cirrus cloud variability over Indian summer monsoon region

Abstract

Climate change is a matter of utmost concern in today s world. Extensive research has newlinedemonstrated that climate change affects the entire ecosystem of our planet, including newlinethe crucial water cycle. While carbon dioxide and methane are commonly identified as newlinethe primary culprits of global warming, it is important to recognise that water vapour newlineis the most prevalent greenhouse gas in the atmosphere. In fact, water vapour in the newlineTropical tropopause layer (TTL) plays a pivotal role in climate feedback due to its newlineexceptional ability to trap heat. The TTL, situated between the troposphere and the newlinestratosphere, serves as a critical layer for regulating the transport of heat, moisture, newlineand pollutants. Changes occurring in the tropical tropopause, such as variations in newlineits height, temperature, and composition, can significantly impact Earth s climate and newlinecontribute to global climate change. Therefore, comprehending the dynamics of the newlinetropical tropopause is crucial for accurately predicting weather patterns, understanding newlineclimate trends, and formulating effective strategies to mitigate the adverse effects of newlineclimate change on human society. newline
