THE HEATING FIELD IN AN ASYMMETRIC HURRICANE PART II:RESULTS OF COMPUTATIONS

This is the second part of a paper on the distribution of heating fields in a hurricane. The first part dealt with the mathematical framework. The second part, i. e. the present paper deals with numerical calculations for an actual hurricane. The following sequence of calculations has been performed after the analysis and tabulation of an initial field of the tangential velocityU (r, , p): (1) the radial equation of motion is used to determine the geopotential heights; (2) the hydrostatic equation is used to determine the temperature field; (3) the tangential equation and the mass continuity equation are combined to obtain an omega equation whose solution determines the vertical velocity; (4) the radial velocity is next determined from the mass continuity equation; and (5) the heating function is finally determined from the first law of thermodynamics. The results of this study show an asymmetric banded structure (eye wall and rainband) of the vertical motion field as well as the heating field; these show close resemblence to observations. An analysis of the non-linearities of the asymmetric momentum distribution is shown to be crucial in the analysis of the hurricane heat sources.
