Abstract : An analysis of hurricane Able (1952) is presented which locates both the eye and the associated hyperbolic point. The results of 2 independent analyses are summarized in terms of the tracks of the cyclonic indraft points and hyperbolic points. The method of direct streamline analysis was employed. The streamlines were first sketched on the basis of strong winds alone, and then extended into the light-wind regions. The asymptotes of convergence and divergence were located on the basis of available wind reports, and greater weights were given to stronger winds. The wind field was analyzed at the reconnaissance flight level for the 2 days for which data were available. No flights were made once the storm entered the coast. The positions of the hyperbolic point at this level are indicated in a diagram together with several positions for higher level maps. The upper wind maps upon which these positions are based are appended. A set of surface streamline maps, together with a brief comment on those winds exceeding 8 knots that were disregarded in the neighborhood of singular points, is also presented in an appendix. The analysis indicated that it may be practicable to track the hyperbolic point as well as the cyclonic-indraft point, and once this is done, the disturbance has an orientation. However, the direction of storm movement may not in general be determined by this kind of analysis.
