A method implementable in a weather-radar system of an aircraft, the weather-radar system configured to generate to a display device, in response to radar return information indicating reflectivity levels below a predetermined reflectivity threshold, an image in a first presentation format. The method includes determining if the altitude of the aircraft is above a predetermined threshold altitude, and, if the altitude of the aircraft is above the threshold altitude, displaying, in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, the image in a second presentation format different from the first presentation format.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A method implemented in a weather-radar system of an aircraft, the method comprising: generating to a display device, in response to radar return information indicating reflectivity levels below a predetermined reflectivity threshold, an image in a first presentation format, determining if the altitude of the aircraft is above a predetermined threshold altitude; and if the altitude of the aircraft is above the threshold altitude, displaying, in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, the image in a second presentation format different from the first presentation format. 2. The method of claim 1, further comprising: determining if the radar return information is reflected from within a threshold distance from the aircraft's present position; and wherein displaying the image comprises displaying the image in a second presentation format if the radar return information is reflected from within the threshold distance. 3. The method of claim 2, wherein determining if the radar return information is reflected from within a threshold distance from the aircraft's present position further comprises determining if the return information is reflected from a position at the same altitude as the aircraft and that the position is along at least one of the aircraft's current heading, track and flight plan. 4. The method of claim 1 stored in a three-dimensional buffer. 5. The method of claim 1, further comprising generating, if the altitude of the aircraft is above the threshold altitude and in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, an audible alarm. 6. The method of claim 1, further comprising generating, if the altitude of the aircraft is above the threshold altitude and in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, a textual image and displaying the generated textual image. 7. The method of claim 1, wherein the first presentation format comprises a first color and the second presentation format comprises a second color. 8. The method of claim 1, wherein the first presentation format comprises a first texture and the second presentation format comprises a second texture. 9. The method of claim 1, wherein the image is generated in the second presentation format only if the radar return information is associated with a reflection within a predetermined altitude range. 10. An aircraft weather-radar system comprising: a display; and a processor coupled to the display, the processor configured to: generate to the display, in response to radar return information indicating reflectivity levels below a predetermined reflectivity threshold, an image in a first presentation format, determine if the altitude of the aircraft is above a predetermined threshold altitude, and if the altitude of the aircraft is above the threshold altitude, displaying, in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, the image in a second presentation format different from the first presentation format. 11. The system of claim 10 wherein the processor is further configured to determine if the radar return information is reflected from within a threshold distance from the aircraft's present position; and wherein displaying the image comprises displaying the image in a second presentation format if the radar return information is reflected from within the threshold distance. 12. The system of claim 10, further comprising a memory configured to store radar return information in a three-dimensional buffer. 13. The system of claim 10, wherein the processor is further configured to generate, if the altitude of the aircraft is above the threshold altitude and in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, an audible alarm. 14. The system of claim 10, wherein the processor is further configured to generate, if the altitude of the aircraft is above the threshold altitude and in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, a textual image and displaying the generated textual image. 15. A computer-readable medium including instructions that, when executed by a processor onboard an aircraft, enable the processor to perform steps comprising: generating to a display, in response to radar return information indicating reflectivity levels below a predetermined reflectivity threshold, an image in a first presentation format; determining if the altitude of the aircraft is above a predetermined threshold altitude; and if the altitude of the aircraft is above the threshold altitude, displaying, in response to radar return information indicating reflectivity levels below the predetermined reflectivity threshold, the image in a second presentation format different from the first presentation format. 16. The medium of claim 15 wherein the steps further comprise storing radar return information in a three-dimensional buffer. 17. The medium of claim 15, wherein the steps further comprise determining if the radar return information is reflected from within a threshold distance from the aircraft's present position; and wherein displaying the image comprises displaying the image in a second presentation format if the radar return information is reflected from within the threshold distance. 18. The medium of claim 15, wherein the first presentation format comprises a first color and the second presentation format comprises a second color. 19. The medium of claim 15, wherein the first presentation format comprises a first texture and the second presentation format comprises a second texture.
