Based on the basic theory of air water resources, the water substances in the atmosphere locked by the secondary circulation formed by the special boundary layer and with the potential of phase transformation into clouds and precipitation are defined as effective water vapor, and then the effective water vapor identification algorithm is developed based on the water vapor convergence area, and the regional exploitable air water resources (i.e. effective water vapor) The total amount and air water resources precipitation potential are evaluated.
& emsp; The source data is the monthly grid data of the new generation typical concentration emission path scenario (rcp4.5) in the fifth coupled mode comparison plan (cmip5). The download address is: https://esgf-node.llnl.gov/search/cmip5/
& emsp; Based on cmip5 three-dimensional specific humidity data, the data resolution is unified as spatial resolution of 0.75 ° × 0.75 °, the precipitable water matrix is calculated by using the integral formula of the whole layer, and the data points in the study area are cut by using Python statistical analysis library to obtain the regional average precipitable water data. Then carry out quarterly average and annual average to obtain seasonal data at all levels in the region.
Statistical analysis was carried out in strict accordance with relevant methods, standards and specifications, and the data quality was good.
