Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for verifying the effect of artificial rainfall in cloud seeding are indirect and struggle to directly analyze the main chemical ingredients of precipitation, particularly in distinguishing between cool and warm clouds, limiting the ability to confirm the impact of seeding materials like silver iodide and calcium chloride.
Innovation Solution
A method and system that calculate the scope of seeding material diffusion, select affected and unaffected regions, perform water sampling before and after seeding, and analyze chemical ingredients based on cloud temperature to verify the effect of artificial rainfall by detecting changes in heavy metal or water-soluble ion components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indirect verification methods (precipitation amount observation, cloud physics observations, radar reflectance analysis) are used, then the verification process can be performed, but the main chemical ingredients (icing nucleus matter or hygroscopic matter) of artificial rainfall cannot be directly verified
Solution Approach 1:
The patent extracts and analyzes specific chemical ingredients (ions and heavy metals) from precipitation samples to directly verify the presence and effect of seeding materials. By taking out and measuring specific chemical components rather than relying on indirect physical observations, the method enables direct verification of cloud seeding effectiveness.
Solution Approach 2:
The patent uses chemical ingredients (ions and heavy metals) as intermediary indicators to verify cloud seeding effects. These chemical components serve as mediators that can be measured in precipitation to infer the presence and impact of seeding materials, providing a direct link between seeding activities and their effects.
2Ease of operation
If a unified analysis method is used for all cloud types, then the verification process is simplified, but the ability to distinguish between cool cloud (silver iodide) and warm cloud (calcium chloride) seeding effects is lost
Solution Approach 1:
The patent applies different analysis methods tailored to specific cloud types and seeding materials. For cool clouds with silver iodide seeding, one analysis approach is used, while for warm clouds with calcium chloride seeding, a different approach is applied. This localized customization ensures optimal verification precision for each specific conditions.
Solution Approach 2:
The patent changes the analysis parameters and methods based on cloud temperature and seeding material type. By adjusting the verification parameters according to whether it is a cool or warm cloud event, the method maintains high precision across different conditions while managing operational complexity through systematic parameter selection.
3Measurement precision
If chemical ingredient analysis is performed on all precipitation, then direct verification is achieved, but the complexity of sampling and analysis procedures increases
Solution Approach 1:
The patent segments the verification process into distinct phases: sampling phase (before and after seeding), analysis phase (separating ions and heavy metals), and verification phase (comparing regions). This segmentation allows complex chemical analysis to be performed systematically and efficiently, managing overall system complexity through structured procedures.
