% Surface wind arrows associated with a specified event at a
% specified time. The radial wind profile is calculated in _windprofilem.m_
% using parameters set in _params.m_ One may also plot the track of the
% event up to the specified time. The wind field includes the effects of
% background wind and wind shear. The parameters _wreduc_ and _wheight_ in
% the _params.m_ file determine whether gradient or surface wind is
% plotted, and what altitude the surface winds represent.

% This version of the script uses the free _m_map_ routines, which are
% included with the script set. Various map properties can be set in
% _params.m_ .
