报告题目:

Long-Standing Anomalies in Cloud Physics, Turbulence and Beyond

摘要:

Despite great effort and progress over the past few decades, a number of challenges are still confronting the field of cloud physics. These cloud physics challenges further hinder progress in areas wherein the role of cloud physics is becoming increasingly critical. In this seminar, I will introduce two long standing anomalies in cloud physics -- droplet spectral broadening and rain initiation. I will discuss their intimate connections with turbulence and entrainment-mixing processes, and the resultant challenges facing the development of various atmospheric models (e.g., large-eddy simulation, cloud-resolving, weather and climate models), and progress of weather modification. I will also discuss my take on the pathways forward from the perspectives of observations, modeling, and development of theoretical understanding and parameterization.

专家简介

Yangang Liu is a Senior Scientist and Leader of the Climate and Process Modeling group of Environment and Climate Sciences Department. His scientific interests have been centering on atmospheric particle systems (aerosols, clouds and precipitation, associated processes and interactions with Earth’s climate. Research spans over a wide spectrum of topics, including aerosol/cloud physics, turbulence, light scattering, radiative transfer, remote sensing, and climate (change). Current research concentrates on development and evaluation of cloud-related parameterizations for models of various scales (from large eddy simulations to cloud-resolving models to numerical weather production models to climate models), and on the effects of aerosols on climate and climate change. Research activities combine development, application, and integration of theory, modeling, and observations. A related interest is to consider particle systems as special examples of broader multiscale complex systems, and seek to quantify fluctuations and explore theories as applied to such complex systems. Research has resulted in 104 peer-reviewed publications in prestigious journals like Nature, Nature-Geo, and Physical Review Letter. Work has been featured by Nature News, American Physical Society, American Institute of Physics, American Geophysical Union, DOE Office of Science, and various news media.
