The Tropical Easterly Jet is the meteorological term referring to an upper level easterly wind that starts in late June and continues until early September. This strong flow of air that develops in the upper atmosphere during the Asian monsoon is centred on 15°N, 50-80°E and extends from South-East Asia to Africa.
The 2023 forecast was crafted meticulously and took a number of critical environmental factors into account. ... The strength of the African easterly jet usually plays a big role in the number of ...
The jet exhibits both barotropic and baroclinic instability, which produces synoptic scale, westward-propagating disturbances in the jet known as African easterly waves or tropical waves. These instabilities, particularly in the presence of moist-convection, cause intense lower-layer cyclonic vortices at the northern flank of the jet. [5]
The 2023 Atlantic hurricane season was the fourth-most active Atlantic hurricane season on record with 20 named storms forming, [nb 1] tied with 1933.Among them, 7 became hurricanes, with 3 reaching major hurricane strength.
The jet exhibits both barotropic and baroclinic instability, which produces synoptic-scale, westward-propagating disturbances in the jet known as African easterly waves, or tropical waves. A small number of mesoscale storm systems embedded in these waves develop into tropical cyclones after they move from west Africa into the tropical Atlantic ...

Two high elevation winds, the African Easterly Jet and the Tropical Easterly Jet modulate atmospheric air flows over Africa and thus also the amount of precipitation; the Tropical Easterly Jet comes from India and is powered by temperature gradients between the tropics [74] and the subtropics while the African Easterly Jet is powered by ...
