Background
The atmospheric water resources in China are very abundant, however, researches show that 14% -18% of water vapor in the atmosphere can form precipitation at most, and even 2% of water vapor in some arid areas, such as Xinjiang areas, only 1.78% of water vapor drops to the ground, and more than 98% of water vapor becomes passing water, so that the atmospheric water resources in China have great development potential. The first step in developing water resources is to accurately evaluate the amount of cloud water resources in the air, i.e. the cloud precipitation potential, in a certain area. Attempts have been made to evaluate existing cloud water data in the air using pattern data, but since no direct observation data is provided, the pattern data has a lot of bias and uncertainty. Cloud precipitation potential is not an isolated value, and comprises cloud water existing in the cloud, horizontal input cloud water and vertical input cloud water, and is closely related to various macro-micro parameters in the cloud. Whether precipitation occurs during northern atmospheric stabilization periods depends primarily on the water vapor supply and the distribution of the updraft, i.e., the amount of condensable water in the atmosphere. The rising motion of air is one of the important conditions of clouding and raining to convey the water vapor of the lower layer to the high altitude. And scholars at home and abroad develop a lot of observation researches on macro-micro physical characteristics of the cloud through foundation equipment, airplanes and satellite detection. However, in cloud water condensables observation due to updraft, no instrument or method is currently available.
