Response of the West African Monsoon to the Madden–Julian Oscillation [PDF]

open access: yes, 2009
Observations show that rainfall over West Africa is influenced by the Madden-Julian Oscillation (MJO). A number of mechanisms have been suggested: 1) forcing by equatorial waves; 2) enhanced monsoon moisture supply; and 3) increased African easterly wave
