ABSTRACT:
A two-layer theoretical
model of hurricanes traveling (quasi-) steadily over open seas has been
developed. The use of coherency concept allowed avoiding the common turbulent
approximations, except a thin sub-layer near the air/sea interface. The model
analytically describes 3D distributions of dynamic and thermodynamic variables
in hurricanes and analyzes processes of evaporation and condensation. Using
this modeling, the following fundamental problems were naturally resolved-change
in the cyclonic/anti-cyclonic directions of hurricane rotation and the directions
of radial wind in lower and upper parts of hurricane; increase in wind angular
momentum in hurricane boundary layer; dramatic effect of ocean spray and its
radial distribution; and a high increase in temperature at the upper region of
boundary layer. Additionally, integral balances allowed expressing the
governing parameters of field variables via two external parameters, the
sailing wind and temperature of a warm air band, in which direction the
hurricane travels. A rude model for the hurricane genesis and maturing has also
been developed.
