Накратко на български

Облаците влияят на климата чрез промяна на състоянието си – например когато ледът в тях се превръща в течност при затопляне. Разбирането на този процес помага за по-точни прогнози относно бъдещите климатични промени, причинени от човека.

Cloud-Phase Feedback and Climate: bridging the gap between observation and simulation

Clouds shape global climate by controlling the amount of solar radiation that is reflected to space and the amount of thermal infrared radiation that is emitted to space. Thus, changes in clouds that are caused by climate warming act as a radiative feedback process that affects climate change. One such feedback mechanism involves changes in cloud thermodynamic phase. As the atmosphere warms, some cloud condensate that would have been ice in the unperturbed climate is replaced by liquid. This makes clouds more opaque, causing them to reflect more solar radiation. It has been hypothesized that cloud-phase changes cause a powerful negative radiative feedback, which dampens climate warming. However, the magnitude of the feedback has been highly uncertain. CPFC seeks to develop new observational and modelling techniques to quantify and understand this feedback mechanism. This is an important step for building confidence in model projections of anthropogenic climate change.

Цел на проекта

Earth’s climate is rapidly changing, with major socioeconomic consequences. A key scientific challenge is to improve climate-model projections by reducing uncertainty in cloud-climate feedbacks. The proposed research will investigate a cloud-feedback mechanism that has a potentially powerful but highly uncertain effect on global climate change. The feedback involves a conversion of ice cloud to liquid cloud that is caused by a warming atmosphere. Our goal is to attain the first quantitative estimate of this feedback based on satellite observations and to develop climate-model software that enables a direct model-to-observation comparison of the feedback. This will close gaps between observational and modeling studies of cloud feedbacks, and it will provide a clear benchmark for assessing climate projections.This fellowship will be carried out in the Department of Geosciences at the University of Oslo under the supervision of Prof. Trude Storelvmo. The research will leverage my expertise in satellite observations and that of the host in climate modeling, thus facilitating a two-way transfer of knowledge. I will gain several new experiences during the fellowship, including working in an interdisciplinary research group, studying in Europe, co-advising graduate students, and engaging with different outlets for public communication. The skills, knowledge, and international network that I will develop will put me in an excellent position to achieve my long-term goal of leading a research group.
