a JJA dust uplift potential (m3 s–3) in P25, b–d JJA dust uplift potential anomalies (m3 s–3, filled contours) and 925 mb geopotential height gradient anomalies (m, line contours) for P25-CP4: b all day average, c 0600–1200 UTC and d 1300–0300 UTC, e, f JJA mean wind speed anomalies (m s–1, colours) and 925 mb geopotential height gradient anomalies (m, lines) for P25-CP4: d 0600–1200 UTC and e 1300–0300 UTC. Grey shading represents non-statistically significant differences at the 5% level. Red symbols in panel a show the locations of the ground stations shown in Fig. 1, where + symbols are the ‘Sahel’ stations (AMMA field campaign), x symbols are ‘Sahara’ stations and the circle is the ‘South Sahara’ station (Fennec field campaign).
