Summary of Available Hail Literature and the Effect of Hail on Aircraft in Flight


Book Description

Available information on the hail phenomenon affecting aircraft in flight has been examined. This paper attempts to coordinate the present knowledge of hail with the effect of hail on aircraft in flight and includes (1) a digest of the literature on the physical properties, the occurrence, and the formation of hai; (2) a survey of the hail effect on aircraft in flight from analyses of 57 cases of airplanes damaged by hail; (3) a resume of hail information for the benefit of pilots, forecasters, and ground operational personnel; (4) an annotated bibliography of 552 articles for use of research personnel.







When Hail Hits


Book Description

Most of the time, hail occurs as tiny pellets not much bigger than gravel or sand. But when the conditions are right, hailstones can be as big as golf balls or even baseballs! They crack car windshields, take down power lines, and even injure people outside when they fall. Readers learn lots of cool science about not just how hail forms, but what conditions need to be for hail to be destructive. Full-color photographs emphasize just how big hailstones can be and how much damage they can cause. Relatable sidebars tackle important details and highlight real-life hail events for interested readers.?




Automatic Detection of Hail by Radar


Book Description

An automated model algorithm for identifying hailstorms by radar is described. Hailstorms are identified by totaling seven weighted indicators based on a three-dimensional reflectivity structure of an ideal hailstorm. The weighting functions for each indicator and the total identifying the storms were determined by testing the algorithm with radar data that were verified by ground truth data. By use of these findings, the probability of detecting hail is 94 percent with a false alarm ratio of 6 percent for a critical success index (CSI) = 0.886 for this test sample.
