Problems solved by technology

Due to the lack of corresponding atmospheric detection means during operations, when judging the potential of artificial rain and snow enhancement operations, we usually mainly refer to the human shadow numerical model forecast products released by the National Human Shadow Center to roughly analyze the liquid water content and ice crystal number concentration in the cloud, and Its development and change trend is carried out, so there are certain deviations and non-objectivity in the operation decision-making

Embodiment 1

[0030] Table 1 shows the hourly observations of liquid water content in clouds, surface precipitation, and PM2.5 concentration of atmospheric fine particles near the surface during a precipitation process in Dalian on November 28, 2016. Through the analysis of the potential index of rain-snow-increasing operation on the hourly observation values ​​of the three elements in this example, it is possible to objectively decide and judge the operation potential in the cloud at any time, as shown in Table 1 and analyzed as follows:

[0031] Table 1 Values ​​of each element in the precipitation process on November 28, 2016

[0032]

[0033] From the analysis of the three elements of the precipitation process in the above table, it is not difficult to see that in different time periods, some clouds have the potential to increase rain and snow, and some time periods have no potential to increase rain and snow. For example, during the time periods of 1, 10, 11, 12, and 13, there is no...

Embodiment 2

[0035] Table 2 shows the hourly observations of liquid water content in clouds, surface precipitation, and PM2.5 concentration of atmospheric fine particles near the surface during a precipitation process in Dalian on November 13, 2015. The analysis of the operational potential index of rain and snow enhancement based on the observed values ​​can objectively make decisions and judge the operational potential in the cloud at any time, as shown in Table 2. The analysis is as follows:

[0036] Table 2 Values ​​of each element in the precipitation process on November 13, 2015

[0037]

[0038] From the hour-by-hour mutual configuration relationship of the three elements observations in the table, combined with the analysis of its operating potential discriminant indicators, it can be seen that there is a lack of ice cores in the precipitation clouds from early morning to 2, 3, 4, 5, and 6 o'clock in the morning, which has great potential Good artificial rain and snow enhancemen...

Abstract

The invention discloses a method for determining the potential of artificial precipitation enhancement, and belongs to the field of weather modification. The method, by selecting three essential elements for cold cloud catalysis, namely liquid water content, ground precipitation and near-surface atmospheric particulate matter concentration, establishes an index system for determining the atmospheric microphysical operation potential of artificial precipitation enhancement. The method uses the real-time observation data in a process of precipitation as an analysis basis of the precipitation enhancement potential, so as to be accurate and objective in the determination of the potential of the artificial precipitation enhancement. The observation data is simple and easy to obtain so that theartificial precipitation enhancement decision is more scientific and practical. The method is an effective method to effectively protect and fully develop the air cloud water resources under a currentair pollution situation.

Description

technical field [0001] The invention relates to the field of artificial weather modification, in particular to a method for decision-making and discrimination of operational potential of artificial rain and snow enhancement. Background technique [0002] Artificial rain and snow enhancement is a technical means commonly used in my country to develop cloud water resources in the air. By choosing the best time to spread the catalyst in the rain cloud system in an appropriate amount to fully develop the cloud water resources in the air and increase the precipitation on the ground, so as to achieve the purposes of agricultural drought resistance, reservoir water storage, forest fire prevention, and urban ecological environment protection. In the process of cold cloud precipitation, not all natural clouds have the conditions to implement artificial rain and snow enhancement operations. Artificial rain and snow enhancement requires that there should be more liquid water in natura...
