RESUMEN
The effect of the equatorial electrojet on the
velocity vector and the temperature of the surrounding environment is modeled by the classical magnetohydrodynamic equations.
Under the assumption of small hydrodynamic and magnetic Reynolds numbers and an
electrojet magnetic field which oscillates along its
axis, z, the nonlinear governing equations are solved
by asymptotic approximation. The effect of the intensity of the magnetic field,
inter alia, on the flow variables are deduced quantitatively. For example, when
the field intensity is small, the temperature distribution is large and vice versa.
Also at the higher approximation, there is a component of the flow variables
which is completely independent of the axis, z, of the magnetic field
variation. Since the classical equation for the temperature is quite similar to
the mass diffusion equation, the present study also sheds light on the effect
of the electrojet on the atmospheric ozone I its
vicinity. Indeed the thermal field and the ozone concentration are affected
similarly.
