Problems solved by technology

[0003] The determination of atmospheric stability requires the use of cloud cover data observed by surface meteorological observation stations. The observed cloud cover is combined with the sun's altitude angle and surface wind speed to determine the atmospheric stability. Low results in limited observation space coverage and too low time resolution to meet the operational requirements of atmospheric environmental assessment

Abstract

The invention provides a determination method of atmospheric stability. The method comprises the following steps: acquiring a plurality of observation subareas in a preset sky observation area of a target site; acquiring meteorological satellite cloud classification data in each observation subarea at each preset moment, and determining cloud types of cloud of different types; aiming at each observation subarea, based on the amount of cloud in the observation subarea, determining total amount of cloud and low amount of cloud of the observation subarea; based on the total amount of cloud and the low amount of cloud of each observation subarea, determining cloud amount information of the preset sky observation area, and determining atmospheric stability of the target site in combination withsolar altitude and ground wind speed. According to the method and the device provided by the embodiment of the invention, by determining the total amount of cloud and the low amount of cloud throughacquiring the meteorological satellite cloud classification data and the cloud amount data in the plurality of observation subareas at a plurality of preset moments, spatial coverage range of the cloud amount observation area is expanded, time frequency of acquiring the cloud amount is improved, and consequently, defects of relatively less weather stations for observing the cloud amount on the ground and poor time resolution are made up.

Description

technical field [0001] The present application relates to the technical field of atmospheric environment, in particular to a method and device for determining atmospheric stability. Background technique [0002] Atmospheric stability refers to the degree to which the buoyancy of the air mass in the air due to the density, temperature, and flow velocity differences with the surrounding air causes it to accelerate and rise or fall. It is an important factor affecting the diffusion of pollutants in the atmosphere. [0003] The determination of atmospheric stability requires the use of cloud cover data observed by surface meteorological observation stations. The observed cloud cover is combined with the sun's altitude angle and surface wind speed to determine the atmospheric stability. Low results in limited observation space coverage and too low time resolution to meet the operational requirements of atmospheric environmental assessment. Contents of the invention [0004] In...
