The Choco low-level jet (Chocojet) is a westerly low-level jet, an extension of the southwesterly cross-equatorial flow that converges over the far eastern Pacific (EPAC) and western Colombia, which exerts a strong modulation over the region's hydroclimate (Poveda and Mesa 1997, 1999, 2000; Mapes et al.
A low-level wind maximum or low-level jet was identified near 5000feet at 215 degrees at 25 knots, with winds less than 10 knots below 1000feet AGL.
The term 'low-level jet' (LLJ) describes a state where the vertical distribution of the horizontal wind speed has a maximum in the lower kilometre of the atmosphere.
In addition, the event site was within or just south of 850 hPa [[theta].sub.e] advection maximum (and convergence maximum) allowing one to infer the low-level jet from the south-southwest.
Although much research has investigated the forcing mechanisms of the low-level jet, no universally applicable paradigm has emerged.
Low-level flows occur during the boreal summer, particularly the Gulf of California low-level jet (Douglas, 1995; Douglas, Valdez-Manzanilla, & Garcia-Cueto, 1998), the Choco low-level jet (CJ, Poveda & Mesa, 2000), and the CLLJ (Amador, 1998, 2008).
Flowing across the Gulf Stream from the east is a low-level jet of air called the warm conveyor belt, which carries the boundary-layer moisture and energy up over the cold-air dam, where the moisture and energy are released, producing heavy precipitation over the coast.
In an active weather pattern, there will be a strong low-level jet in the upper portions of the tropical air, with winds often exceeding 50 knots with a risk of low-level wind shear.
The existence of a low-level jet off the west coast of South America at about the 950 hPa level has been stated for regions further south from northern Chile to central Peru (Garreaud and Munoz [15], Toniazzo et al.
Four key features were then identified: (1) cyclogenesis in the Gulf of Mexico, (2) an anticyclone advecting cold arctic air into the region, (3) an upper level shortwave trough approaching the region and (4) a low-level jet (LLJ) in advance of the trough.
