Fig. 2: Backwards trajectories of the flights for each Anopheles capture event.
From: Windborne long-distance migration of malaria mosquitoes in the Sahel
Backward 9-h trajectories were estimated by HYSPLIT (Table 2), and are overlaid on a map showing parts of Mali and neighbouring countries. Map data are from Google, Landsat/Copernicus 2019. Each line represents one of four simulated trajectories of one (or more) mosquitoes intercepted at that location and on that night. The area encompassed by the four trajectories is shadowed. Migration season is shown by line colour. The Anopheles species is indicated above each panel. D, M, S and T are the balloon launch locations in the villages of Dallowere, Markabougou, Siguima and Thierola, respectively. Scale bars, 100 km. The seasonal-wind rose diagrams, reflecting wind conditions at 180 m above ground level averaged from 2013 to 2015, are shown at the right.
