[PDF] Top 20 Weak interaction in the African Easterly Jet

... The duration of the interaction between waves is given by half of the period of the elliptic function (2K), since ε k is proportional to ψ 2 k . The energy ε k of each wave as a function of time for N 2 /N 1 =0.7 ... See full document

... precipitation: the SMD increases total accumulated rainfall by ∼10% and shifts the region of precipitation ∼5° north. The strength of AEWs and their track locations are also important for tropical cyclogenesis, since ... See full document

... note was that during these seasons the AEJ propagated northward, moving into the Saharan Desert rather than staying by the rainforests to the south. This result is easier seen using the every 10 day plots rather than ... See full document
