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.
<p>  (1) The daily average data of real-time reanalysis data (era Interim) of European Mesoscale Weather Prediction Center (ECMWF) can be downloaded from: https://apps.ecmwf.int/datasets/data/interim-full-daily/levtype=sfc/
& emsp; (2) The grid data of monthly surface precipitation in China from the National Meteorological Information Center can be downloaded from: http://data.cma.cn/data/detail/dataCode/SURF_CLI_CHN_PRE_MON_GRID_0.5.html
& emsp; (1) Download the grid data of monthly surface precipitation in China from the National Meteorological Information Center, and unify the spatial resolution to 0.75 ° × 0.75°。
& emsp; (2) Download era interim runoff data and unify the spatial resolution to 0.75 ° × 0.75°。
& emsp; (3) The runoff coefficient can be obtained by calculating the ratio of precipitation to runoff at each grid point.
& emsp; (4) Finally, the seasonal average and annual average are carried out to obtain the seasonal data at all levels in the region.
<p> Statistical analysis was carried out in strict accordance with relevant methods, standards and specifications, and the data quality was good.
