Biography

Xia Sun joined NCICS in August 2022 as a climate data analyst with the National Climate Assessment Technical Support Unit. After earning her bachelor’s degree from Nanjing Institute of Meteorology, also known as Nanjing University of Information Science & Technology, Xia attended North Carolina State University, where she continued her research in Atmospheric Science with enthusiasm. During her master’s study, Xia focused on coupling the atmospheric Weather Research and Forecasting (WRF) model with a modified oceanic POM model and adapting the completed version to carry out regional weather and climate research over Lake Victoria Basin, East Africa. Since then, Xia has participated in the Future Climate for Africa (FCFA) programs aiming to enhance the understanding of East African climate variability and change. In 2021, Xia completed her PhD study in Atmospheric Science, with a minor in Statistics. Her doctoral research has revolved around increasing preseason hurricane forecast accuracy. She developed and improved a probabilistic model to better predict the Atlantic hurricane season with optimization through machine learning techniques. Since 2017, the developed model has been used for hurricane forecasting, with Xia participating in the release of the hurricane season outlooks around mid-April every year. Additionally, her projects involved numerical modeling simulations of tropical cyclones,long-term climate predictions for different areas, and quantitative and qualitative data analysis and visualization. At this point, Xia is more broadly interested in hurricane forecasting, climate change, numerical modeling, and data analysis.
