I am a 2nd year engineering student at École Centrale de Nantes where I study statistics and data science. My internship at INRAE and AgroParisTech revolves around studying the risk of late spring frost in the context of climate change. To this purpose, we model two indicators used to quantify the risk of damaging late frost, using extreme value theory. We then extend our modeling to a spatio-temporal study of the phenomenon with the use of hierarchical models, which explain in different ways the evolution of the said risk in light of climate change. This evolution can be complex in the sense that it can vary spatially and our study could identify sites that have a higher risk of spring frost damage, motivating more efficient preventive measures.
