Patent attributes
Systems and methods for improving relevant weather determination for aircraft at altitude. An exemplary system includes a weather radar component and memory that stores weather radar data in a three-dimensional (3D) buffer. A processor calculates vertically integrated reflectivity using the stored weather radar data at a predefined reference altitude at one or more locations from the aircraft. The processor then adjusts a lower boundary of a relevant weather envelope from a first value to a second value, if the vertically integrated reflectivity is greater than a predefined threshold. The range of the adjusted lower boundary of the envelope is associated with the weather radar data having the calculated vertically integrated reflectivity greater than the predefined threshold. A display device displays the weather radar data located within the envelope in a first manner and displays the weather radar data located outside of the envelope in a second manner.
