Assessment method for influence of aircraft contrail generation on global surface temperature

Abstract

The invention provides an assessment method for an influence of aircraft contrail generation on global surface temperature. The method comprises the following steps of (1) building a meshing assessment model of a global range; (2) according to meteorological conditions in to-be-assessed meshes, judging a contrail generation situation; (3) according to an air route structure and a flight flow distribution characteristic, calculating a contrail generation frequency index (CFI); (4) through an absolute global temperature potential (AGTP), assessing the influence of the contrail generation on the surface temperature in the to-be-assessed meshes after K years; and (5) performing statistics on heating conditions of all the to-be-assessed meshes, and drawing a global surface heating graph. According to the assessment method for the influence of the aircraft contrail generation on the global surface temperature, the blank of research on a technology for assessing a range of the influence of the aircraft contrail generation on the global surface temperature at home and abroad is made up for, and the global heating graph is accurately drawn on the basis of obtaining historical data of the meteorological conditions, the air route structure and the flight flow.

Description

[0001] Technical field: [0002] The invention relates to a method for evaluating the influence of contrail formation of aircraft on the global surface temperature, in particular to a method for judging the formation of contrail formation of aircraft and an evaluation method for the influence of formation of contrails on surface temperature. [0003] Background technique: [0004] A comprehensive and accurate assessment of the impact of the greenhouse effect on surface temperature is conducive to the reasonable and efficient control of global warming. Aircraft contrails are one of the important indicators of the global warming effect. At present, qualitative and quantitative analysis and assessment of the impact of warming are mainly carried out. With the rapid increase of air traffic volume and the enhancement of people's awareness of environmental protection, the environmental impact of air traffic is also increasingly concerned, especially the need to control the impact of g...

AI Technical Summary

Problems solved by technology

[0005] Scholars at home and abroad mainly study the impact of surface temperature changes from the perspective of greenhouse gases, and have not comprehensively considered the impact of aircraft contrail formation on surface temperature changes. The research is still blank, but the environmental carrying capacity is limited. In order to ensure the continuous stability of air traffic development, environmental capacity is an insurmountable gap, so the impact of aircraft contrail formation on global surface temperature is an important research that needs to be carried out urgently
