| 摘 要： | By adopting the β plane approximation in the neighbourhood of the equator and neglecting the nonlinear terms in the barntropic primitive equations, particular solutions art obtained under the steady condition. From these, we find that in the neighbourhood of the equator, the large scale low level jet (LLJ) is mainly determined by the inertia effect of the earth's rotation, the depth of the equivalent fluid layer and the frictional effect of the earth's surface. By using the Green function to obtain an exact solution for the system of equations, the meridional component is obtained. However, the low level wind fields obtained by both approaches generally agree with the actuality.
