| Abstract: |
| In this talk a model of the evolution of a typhoon is considered
and studied numerically. We consider the motion of the air in a
cylindrical domain with axial symmetry. Neglecting the viscosity
and the heat-conductivity, we transform the equations in those on
the trajectories of the air. On each trajectory the process of
condensation of water vapor in ascending flow of wet air and the
consequent heating by the latent heat are described. The force
pushing upwards the air is determined directly by the relation
with the pressure in the external region. The result of numerical
computation shows the increase of the wind due to the latent heat
of the condensation and the stabilization due to the accumulation
of liquid or solid water in the air, which brakes down the
ascending motion of the air. |
