Getting creative with Rain🌧⛈🌦 - Cloud Seeding.
Rain, cloud thunderstorms all these are considered as nature's gift by each and every person on earth. But when out there exists a scientific method that can create weather itself as per needs and even is controlled by human beings, How will that put an effect on everyone?
Cloud seeding is a type of weather modifications that aims to change the amount or type
of precipitation that falls from clouds by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud.
HOW DOES IT WORKS?
When cloud seeding, increased snowfall takes place when temperatures within the clouds are between −4 and 19 °F (−20 and −7 °C).Introduction of a substance such as silver iodide, which has a crystalline structure similar to that of ice, will induce freezing nucleation.
In mid-altitude clouds, the usual seeding strategy has been based on the fact that the equilibrium vapor pressure is lower over ice than over water. The formation of ice particles in supercooled clouds allows those particles to grow at the expense of liquid droplets. If sufficient growth takes place, the particles become heavy enough to fall as precipitation from clouds that otherwise would produce no precipitation. This process is known as "static" seeding.
METHODOLOGY
Cloud seeding chemicals may be dispersed by aircraft or by dispersion devices located on the ground (generators or canisters fired from anti-aircrafts or guns) . For release by aircraft, silver iodide flares are ignited and dispersed as an aircraft flies through the inflow of a cloud. When released by devices on the ground, the fine particles are carried downwind and upward by air currents after release.
An electronic mechanism was tested in 2010, when infrared laser pulses were directed to the air above Berlin by researchers from the University of Geneva.The experimenters posited that the pulses would encourage atmospheric sulfur dioxide and nitrogen dioxide to form particles that would then act as seeds.
Cloud seeding has been the focus of many theories based on the belief that governments manipulate the weather in order to control various conditions, including GLOBAL WARMING populations, military weapons testing, public health, and flooding.
These theories never come up and neither are taught us by our teachers. Some of these
theories are very important of its related to being controlled by some of the humans.
