Problems solved by technology

The above inversion methods of existing technologies have the problem of low spatial and temporal resolution, and cannot meet the requirements of the mesoscale characteristics of the dynamic tropopause and other related synoptic and climate studies. Therefore, a new method for inverting the height of the atmospheric dynamic tropopause is needed (atmospheric pressure) method to obtain dynamic tropopause height with higher spatio-temporal resolution

Abstract

The invention discloses a meteorological satellite dynamic tropospheric top height inversion method, and the method comprises the following steps: obtaining the data and positioning information of a real-time static meteorological satellite imager, and calculating the brightness temperature of a middle-layer water vapor channel, the brightness temperature of a high-layer water vapor channel and the brightness temperature of a long-wave infrared channel; acquiring real-time three-dimensional temperature field information of the numerical forecasting mode, and performing space-time matching witha meteorological satellite; obtaining the average specific humidity of the middle layer and the high layer of the troposphere, inputting the obtained prediction factor data into a regression prediction model, and obtaining the top height of the dynamic troposphere through an inversion calculation formula; and outputting a result obtained by inversion calculation according to pixels. The tropospheric top height result obtained through the inversion method is consistent with the inversion result in the prior art, effectiveness is achieved, dynamic tropospheric top height data with higher spatial resolution and time resolution than an existing inversion method can be obtained, and obtaining of mesoscale structure information and weather and climate characteristics of the tropospheric top isfacilitated.

Description

technical field [0001] The invention relates to the technical field of meteorological remote sensing, in particular to a method, device, storage medium and computer equipment for retrieving the height of the tropopause powered by a meteorological satellite. Background technique [0002] The tropopause is the upper boundary of the troposphere, the transition layer between the troposphere and the stratosphere. In this region, atmospheric properties such as potential vorticity, water vapor, temperature, and chemical property levels such as ozone, sulfur dioxide, carbon dioxide, and many nitrogen oxide concentrations undergo abrupt changes. The tropopause of the atmosphere is not only affected by weather development and has diurnal variation characteristics, but also changes with latitude and seasonal changes. [0003] From the end of the 19th century to the present, various definitions of the tropopause have been given internationally from different perspectives, for example, ...
