Abstract

The invention discloses a method for continously observing and determining the vertical distribution of atmospheric water vapor by using superconductive gravity and relates to a method for determining the vertical distribution of the atmospheric water vapor. The method comprehensively uses earth tide theory, observation technology, atmosphere load gravity correction theory and simulates global surface pressure temperature observation data and the like which eliminate other phenomena except that the atmosphere acts on the gravity on the station above 50 kilometers away from the surface of the ground point of an observation station, to obtain ground point gravitation which the atmosphere in an area acts on; and then atmosphere vertical water vapor is inversed. The method is a fire-new method, is added with a new observation means, and can increase the observation time and spatial resolution of the atmosphere vertical water vapor. Combined with the observation of the wind speed and wind direction, the method can be used for observing three-dimensional water vapor distribution and increases the accuracy of weather forecast.

Description

technical field [0001] The invention relates to a method for determining the vertical distribution of atmospheric water vapor, in particular to a method for determining the vertical distribution of atmospheric water vapor by using superconducting gravity continuous observation. Background technique [0002] The water vapor content in the air is an important parameter in meteorology, especially weather such as precipitation and snow is closely related to production, life and military operations, and the accuracy of forecasting is particularly important. For a long time, the observation of water vapor distribution in space has mainly relied on sounding balloons and water vapor radiometers. The spatial and temporal density distribution of the data is very limited. People have been trying to improve the observation of water vapor content in space, and have spared no expense in researching ground-based and space-based meteorological element observation technologies, such as wate...
