Problems solved by technology

[0003] The Qinghai-Tibet Plateau is a huge natural body raised on the surface of the earth. The average altitude is about 4000m, but the actual effective height can reach 6000-7000m. The distribution of water vapor has a great influence on the regional weather and climate. Therefore, the observation of atmospheric water vapor on the Qinghai-Tibet Plateau is very important. Air sounding observation is a common method for atmospheric water vapor observation. However, there are large errors in sounding observation, which leads to data No, the observation of atmospheric water vapor cannot be accurately realized, which affects the accuracy and effectiveness of atmospheric observation. In the existing technology, there are very few studies on the error of atmospheric water vapor in radiosonde observation, especially how to improve There is no effective method for observing the accuracy of atmospheric water vapor

Abstract

The invention discloses a method for observing atmospheric water vapor of Qinghai-Tibet Plateau through sounding. The method comprises the steps of S100 collecting data and processing the data; S200 performing sounding observation to obtain data; and S300 calculating the total amount of sounding observation atmospheric water vapor in the sounding observation area. According to the the method for observing atmospheric water vapor of Qinghai-Tibet Plateau through sounding, a database is established by collecting meteorological data over the years of an area with a foundation GPS station and a sounding observation station; a GPS remote sensing atmospheric water vapor total amount curve graph of the foundation GPS station over the years is creatively used as a basis; the solar zenith angle isproposed; the ground temperature of the environment where the sounding observation station is located is an important factor influencing the total amount of atmospheric water vapor for sounding observation; a revision formula for sounding observation of the total amount of atmospheric water vapor is creatively proposed; and the accuracy of sounding observation of the total amount of atmospheric water vapor is greatly improved.

Description

technical field [0001] The invention relates to a method for air sounding observation of atmospheric water vapor in the field of meteorology, in particular to a method for air sounding observation of atmospheric water vapor in the Qinghai-Tibet Plateau. Background technique [0002] Water vapor is a trace gas in the earth's atmosphere. It accounts for a very small proportion in the atmosphere, only 0.1% to 3%, but it is the most active component in the atmosphere. Compared with other trace gases, water vapor is more important. Weather phenomena are mostly the result of changes in atmospheric water vapor. Water vapor absorbs and releases a large amount of latent heat during the phase transition process, directly affecting the ground and air temperature, and further affecting the vertical stability of the atmosphere and the formation of convective weather systems. The three-dimensional distribution of atmospheric water vapor, vertical transport of water vapor and phase transit...
