to January 1999 (a–c)
south of Tenerife (Figs. 5.4g and 5.6c). Once the coalescence process was completed, A1 resumed its southwestward displacement (Figs. 5.4h, 5.5 and 5.7a) at
an estimated mean speed of ∼ 4.6 cm s

middle of December (Fig. 5.7b), when the eddy reached a latitude next to 26
◦ N, it
advanced westward (Figs. 5.4i, 5.5 and 5.7c) at an estimated mean speed of ∼ 3.5 cm
