Has it been raining more lately?

Cloud seeding is a weather modification technique that involves dispersing substances into the atmosphere to encourage the formation of rain or other forms of precipitation. The substances used for cloud seeding are typically silver iodide, potassium iodide, or other chemicals that can act as ice nuclei.

The process of cloud seeding aims to enhance the natural processes of cloud formation and precipitation. By introducing these substances into clouds, it provides additional particles around which water vapor can condense and freeze, forming ice crystals. These ice crystals then grow and eventually fall as precipitation, such as rain, snow, or hail.

Cloud seeding can be performed in various ways. One common method is aerial cloud seeding, where aircraft disperse the seeding agents into targeted clouds. Ground-based generators can also be used to release the substances into the air. The choice of method depends on factors such as the type of clouds, atmospheric conditions, and desired outcomes.

Cloud seeding is often used in regions experiencing water scarcity or drought conditions. The goal is to increase precipitation and potentially augment water supplies. However, the effectiveness of cloud seeding can vary depending on several factors, including the availability of suitable clouds, atmospheric conditions, and the seeding techniques employed.

While there is scientific evidence suggesting that cloud seeding can increase precipitation under certain conditions, its effectiveness is still a subject of ongoing research and debate. The results of cloud seeding operations can be challenging to evaluate due to the complexity of weather systems and the difficulty in establishing controlled experiments.

It is worth noting that cloud seeding is regulated in many countries to ensure it is conducted safely and responsibly. Environmental considerations, potential impacts on ecosystems, and public safety are important factors in implementing cloud seeding programs.

I remember the Australian fires causing discolouration in our skies in Aotearoa New Zealand and reduction in sunlight for some time. So is regulation going to stop clouds from travelling from one area to another? 

All of this begs the question. What does mother nature think? Is she happy and does common sense say we wouldn't affect the natural balance? And just because we can, should we? I'll leave you to ponder and contemplate ...
