Observations show that the deep equatorial circulation is surprisingly energetic,with alteroating eastward and westward soml currents (these flows are commonly referred to as the deep equatorial jetis) betwew 1 000 and 3 000 m.This paper shows that the waves generated by an off-equatorial deep buoyancy oscillation,and their energy radiation as well as the equatorial focus of waves energy are the viable dynamic mechanisms of forming the deep equatorial jets. The results of testing the effects of vertical mixing coefficients on the jets show that as the coefficients increase,the jets become waster and their tonal coherent scales become longer. The solatbns for different periada of forcing indicate that lengthening the period of forcing results in the position of the core of the deep jets to moving westward and also enhances the tonal coherent scales of the jets.
