Abstract

The invention provides an airspace convective weather information quantification method based on matrix operation, and the method comprises the steps: calculating an airspace structure matrix for a target sector according to a two-dimensional matrix of convective weather data subjected to two-dimensional lattice processing, wherein the airspace structure matrix uses different element values to represent different airspace properties in the target sector; and then in combination with transformation of the spatial domain structure matrix elements, calculating and using convective weather quantitative indexes in the spatial domain for quantitatively describing convective weather intensity and range information in the spatial domain range, wherein the convective weather quantitative indexes comprise coverage rate and intensity of convective weather reflectivity in a target sector. The convective weather information in the airspace is objectively quantified by using matrix operation thinking, quantitative index reference can be provided for air traffic control decisions such as capacity evaluation and flow control strategy making in the airspace, and safe and orderly operation of air transportation under the convective weather condition is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aviation meteorology, in particular to a method for quantifying airspace convective weather information based on matrix operation. Background technique [0002] Civil aviation passenger planes need to follow the planned route and fly according to the control instructions of the air traffic control department. The air traffic control department uses the sector as the control unit to control the flow of aircraft in the sector, monitor and control in real time. When convective weather occurs in the sector, especially on the route within the sector, the controller's workload will suddenly increase, and the safe flight of the aircraft will also face challenges. In the current air traffic control operations, the impact of convective weather on the flight of a sector or route is mostly represented by qualitative impact levels of red, yellow, and green. On the basis of such qualitative conclusions, the flow manag...
