Prof. Sergey K. Gulev is a member of the Russian Academy of Sciences and holds a Doctor of Science degree in Physics and Mathematics. He is the head of the Sea-Air Interaction and Climate Laboratory (SAIL) at the Shirshov Institute of Oceanology, Russian Academy of Sciences. Prof. Gulev has made significant contributions to the fields of sea-air interaction, marine meteorology, and climate dynamics. To date, he has published over 400 papers in journals such as Nature, Nature Geoscience, and BAMS. He played a key role in designing and organizing unique experiments such as NEWFAEX-88 and ATLANTEX-90. He was the first to develop a wind-wave climatology for the North Atlantic using observational data, laying the foundation for estimating wind-wave interaction momentum fluxes. Under his leadership, his research team developed a century-scale global ocean wind-wave climatology, which has become widely used in ocean climate studies. Additionally, he led the creation of the most comprehensive climatology of cyclone activity to date and developed numerical methods for cyclone identification, which have been widely used.

[Rachel White]

Dr. Rachel White is an Assistant Professor in the Department of Earth, Ocean and Atmospheric Sciences at the University of British Columbia, Canada. Her work focuses on large-scale climate dynamics and their impacts on extreme weather events, including the simulation of atmospheric dynamics and climate extremes in climate models. Her research includes studies on the June 2021 heatwave in the Pacific Northwest of North America, one of the most extreme heat events on record, research on whether we can use the connections between large-scale atmospheric dynamics and extreme weather events to improve sub-seasonal to seasonal (S2S) forecasts of extremes, through to more theoretical questions, such as work to understand the role of topography and sea surface temperature asymmetries on the atmospheric circulation patterns that can lead to temperature extremes. Rachel serves as an Associate Editor for the Journal of Atmospheric Sciences, is a lead author for two chapters for the latest Canada’s Changing Climate Report (2025), and a lead author for a chapter on Stationary Waves in Climate models in new Elsevier Encylopedia of Climate System Science.

[Fangqun Yu]

Prof. Fangqun Yu is a tenured faculty member and research professor of the Atmospheric Sciences Research Center at the University at Albany, State University of New York. Recognized recently with the 2024 SUNY-Albany President's Excellence in Research and Creative Activities Award, he is an internationally renowned scientist on the formation of particles and contrails in aircraft plumes, theories of new particle formation in the atmosphere, size-resolved particle microphysics, and climatic and environmental impacts of atmospheric particles. He develops and applies a size-resolved advanced particle microphysics (APM) model across plume, local, and global scales. The APM model has been coupled with widely used community models, including GESO-Chem, WRF-Chem, WRF-CMAQ, CESM2, and E3SM. His recent research employing APM at both plume and global scales has shed significant new insights into solar radiation modification (SRM) via stratospheric aerosol injection (SAI). His group is also working on connecting the contrail cirrus study to cirrus cloud thinning (CCT) and shipping emission to marine cloud brightening (MCB), the other two proposed approaches of SRM. With over 180 peer-reviewed publications and a Google Scholar h-index of 57, his work spans fundamental particle microphysics, aerosol-cloud-climate interactions, contrail formation and climate implications, health effects of ultrafine particles, machine learning applications in global aerosol modeling, and climate intervention.
