Advancements in Solar-Terrestrial Research and Meteorology

The Solar-Terrestrial Centre of Excellence (STCE) focuses on ongoing activities and opportunities in the field of meteorology, with a special emphasis on Antarctica. Their annual meetings cover topics like water vapor feedback mechanisms, extreme weather events forecasting, cloud and precipitation studies, and advancements in nowcasting systems. Collaborations with various meteorological fields aim to improve convective cell forecasts. The STCE is at the forefront of research and innovation in solar-terrestrial studies.
