Horizontal wind systems in the ionospheric
E region are deduced from the dynamo theory by using the same total electric field as in Part I. [1] In Part II the effect of the Coriolis force is taken into consideration and a further study is made about the wind motion in the
E region. The wind velocity is obtained by solving the equation of motion of the atmosphere for the rotating earth simultaneously with the dynamo equation.
It is shown as in Part I that the diurnal wind motion predominates over the semi-diurnal one in the
E region and the semi-diurnal pressure variation is almost in phase with that observed at the ground.
The conspicious differences in the results between Part I and Part II are: (1) The diurnal pressure variation in the
E region reaches its maximum value at about 7p.m. local solar time in Part II instead of at 9a.m. as in Part I. (2) Amplification of the semi-diurnal pressure variation in the
E region is estimated to be 25-30 at low latitudes in Part II instead of 50 as in Part I.
The vertical drift velocity in the
F2 region is calculated by using our wind-systems.
In Appendices the mathematical consideration is given to our treatment.
