Abstract: | A plane problem of generation of barotropic seiches in a bounded rotating basin by traveling atmospheric fronts is studied
within the framework of the linear theory of long waves. The front is characterized by disturbances of the baric field and
the corresponding field of tangential wind stresses. We deduce the modified Ackerblom formulas for the wind stresses according
to the given anomalies of atmospheric pressure in which the uniform transport of disturbances of the baric field is taken
into account. We perform the numerical analyses of the dependences of the amplitudes of oscillations of fluid in the basin
on the parameters of the atmospheric front and the choice of the formulas for the tangential wind stresses. The influence
of the wind stresses leads to significant quantitative and qualitative changes in the oscillations of fluid in the basin as
compared with the case of pure baric action. |
