[摘要] (i) Discussion of the criterion of horizontal stability in frontal zone.Estimating the magnitude of each factor in determining horizontal stability in frontal zone, we obtained the following simple results: where l denothes the horizontal velocity gradient and β the angle that the frontal zone makes with the meridional circle. From the above formula, we have derived the relation between the width of the frontal zone and latitude.(ii) Stability of secondary discontinuity produced between two cyclones.Using the above criterion, we discussed the orientation of the secondary discontinuity produced between two cyclones.
