Mémoire
Résumé : | In this study, we investigate the convective vortices and the existing horizontal, zonal and meridional correlations. We focus on 400 Martian (sol) days, corresponding to Earth dates from 30 November 2018 to 11 January 2020. Using data from the InSight lander, we have analysed the pressure profiles of more than 400 Martian days to explore the pressure drops, with a focusing on formation conditions and hence the potential presence of dust devils. Our analysis revealed distinct patterns in the periods of dust activity, zonal wind speeds and the intensity of pressure drops, influenced mainly by the presence of dust. The greatest number of convective vortices was observed during the calm period from sol 118 after InSight’s landing, which also corresponds to a period when a strong correlation is found between zonal winds and the formation of convective vortices. Given the metereological conditions at the landing site, we support the presence of dust devils among the results found in this work, even though InSight has never been able to photograph this type of event. |
