| Clear air turbulence (CAT) is one of the most significant causes of delay and economic losses for airlines (e.g. Kauffmann, 2002; Sharman, 2016), as well as being a source of passenger discomfort and incidents, which can lead to physical injury (Williams, 2017; Kharoufah et al., 2018). Several studies have shown that CAT on transatlantic flights between Europe and the United States has increased due to global warming (e.g. Storer et al., 2017 and 2019; Williams et al., 2013). In a recent study (see below) based on ERA5 reanalysis data at pressure levels of 200 and 225 hPa, variant 1 of the Ellrod index has been used to evaluate the CAT at cruising altitudes over Europe. The study analyzes trends at monthly, seasonal and annual timescales, and the probability of finding moderate or intense turbulence (MOG) following the methodology of Prosser et al. (2023). This study has shown interesting preliminary results, but a more detailed analysis in aspects is recommended.
The work proposed here aims to: - Analyze CAT over a larger domain centered in Europe that includes southern latitudes to determine the role of the subtropical jet stream in the formation of CAT. - Extend the analysis period, from the mid-20th century to the present, to be able to detect possible CAT patterns and relate them to other cycles (for example, solar cycles, ENSO phenomena, NAO, ...). - Analyze the role of the great mountain ranges of Europe (especially the Alps) in the formation of CAT - Apply additional indexes to quantify CAT. https://mitra.upc.es/SIA/PFC_PUBLICA.DADES_PFC?w_codipfc=11889 |
