Abstract

The invention provides a data processing method for water-vapor fluxes under climatic change scenes. The method comprises the following steps of: obtaining environment data, comprising a wind direction, a wind speed and specific humidity data of a vertical layer, of a to-be-researched area; and determining a water-vapor flux by utilizing the environment data and a preset water-vapor flux corresponding relationship. According to the method, the wind direction, wind speed and specific humidity data of the vertical layer are considered in the environment data, so that the error problems caused byinsufficient reference quantity are decreased and the water-vapor flux processing results are more correct and reliable. The invention furthermore provides a data processing device for water-vapor fluxes under climatic change scenes.

Description

technical field [0001] The invention relates to the technical field of hydrometeorology, in particular to a data processing method and device for water vapor flux under climate change scenarios. Background technique [0002] In recent years, with the intensification of global changes, extreme drought and flood events have occurred frequently. In order to adapt to and mitigate the negative effects of climate change, it is necessary to accurately predict rainstorm events. One of the necessary conditions for the formation of rainstorm is to have enough water, and the rainstorm cannot be formed only with the existing water in the study area, and the rainstorm needs to be continuously input into the study area to form a rainstorm. Therefore, in order to predict rainstorm events, it is necessary to calculate the water vapor flux in the study area. [0003] Water vapor flux refers to the mass of water vapor flowing through a unit cross-section orthogonal to the velocity vector pe...
