Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an analysis method, device and storage medium for the effect of artificial heat warming. Background technique [0002] Anthropogenic heat emission refers to a large amount of waste heat discharged into the surrounding environment due to insufficient utilization of energy in people's production and life. It is one of the important input variables of urban energy systems. Production and living activities in cities, including industry, transportation, and residential life, all emit a large amount of waste heat, which affects the energy balance of the urban surface and intensifies the urban heat island effect. One of the important prerequisites for quality improvement. [0003] At present, the existing methods for assessing the effect of man-made thermal warming mainly include the energy inventory method, the remote sensing inversion method and the numerical simulat...

Problems solved by technology

[0003] At present, the existing methods for assessing the effect of man-made thermal warming mainly include the energy inventory method, the remote sensing inversion method and the numerical simulation method. With the city as the smallest unit, it is impossible to quantitatively express the anthropogenic warming effect inside the city, and has the defect of low resolution; the remote sensing inversion method involves more empirical equations, and the addition of empirical parameters often reduces the simulation accuracy, and The acquisition of most variables needs to be replaced by a difference or a single point value, so that the anthropogenic thermal simulation of the entire area can only be determined by one value, which greatly reduces the accuracy of the inversion results; the numerical simulation method has high requirements for computing resources and a long computing cycle , it is difficult to grasp. In addition, the anthropogenic heat emission in the WRF model is a default fixed value, which cannot reflect the real situation of anthropogenic heat emission
