| Abstract: | Observations show that the deep equatorial circulation is surprisingly energetic, with alternating eastward adn westward zonal currents(these fkows are commonly referred to as the deep equatorial jets) between 1 000 and 3 000 m. This paper shows that the waves generated by an off-equatorial deep buoyancy oscillation, and their energy radiatin as well as the equatorial focus of waves energy are the viable dynamic mechanisms of forming the deep equatorial jets.The results of testinh the effects of vertical mixing coefficients on the jets show that as the coefficients increase, the jets become weaker and their zonal coherent scales become longer.The solutions for different periods of forcing indicate that lengthening the period of forcing results in the position of the core of the deep jets moving westward and also enhances the zonal coherent scales of the jets. |
