Abstract
Systems and methods for representing a weather hazard without also including a large percentage of non-hazard area. An exemplary system includes a memory that stores radar reflectivity data in a three-dimensional buffer, a display device and a processor that is in data communication with the memory and the display device. The processor receives a two-dimensional shape based on a portion of the data stored in the three-dimensional buffer, then finds a center of the shape. Next the processor finds the furthest away point of the shape in a plurality of regions sharing the center as a common point and generates a polygon based on the furthest away points. The display device displays the generated polygon. The shape is associated with hazardous weather information determined from the radar reflectivity data stored in the three-dimensional buffer. The display device is an aircraft weather radar display.
