Query: A Chi Distribution Model of Hail Storm Damage   This paper addresses the pattern of damage, and investigates its properties,
of a theoretical hail storm which gathers in intensity before subsiding, and
which travels linearly across the landscape at constant velocity. We start by
assuming a simpler model, that of a storm which does not move, restricted to
having an uncorrelated binormal distribution of damage. This model, expressed
in the natural polar coordinates, leads to a 1-dimensional pattern of damage as
a function of the marginal radial distance conforming to the
$\chi$-distribution with two degrees of freedom. The model is then extended to
the traveling form, allowing further for a correlation of the variables,
extending, as well, to the multidimensional case. In its full florescence the
model produces hyperellipsoidal hypersurfaces of equal intensity for the
correlated multinormal assumption. We provide closed-form solutions for the
totality of damages upon these hypersurfaces as proxies for the insurance
claims to follow. Finally the model is applied to extensive datasets of hail
events, as detected by the NEXRAD network of weather radars.
