Can we make it rain? Cloud Seeding. Does it work?

Cloud seeding is focused primarily on increasing snow pack and precipitation over farmland. The key to cloud seeding is supercooled water.  Supercooled water is a liquid with a temperature below freezing.  Adding silver iodide, liquid nitrogen, or dry ice causes supercooled water droplets to freeze.  As the liquid droplets freeze, the growing ice crystals become heavy and fall to the ground. How is the silver iodide dispersed? Once the ideal weather condition has been determined, dispersal is performed by both ground based generators and aircraft.  Aircraft can be fitted with pyrotechnic flares or dry ice dispersal.     Read more »

Rainbows

Rainbows... Beautiful but what are they? Rainbows are raindrops and sunlight interacting in the perfect way. Just like a prism, light hits a drop of water and forms brilliant colors. White light enters a raindrop which has a different density than the surrounding air. Due to the changes in density, raindrop density compared to the density of air, the speed of the light changes. The change in speed causes the light to bend (angle of refraction). The light bends as it enters the raindrop (refraction) and then reflects off the back of the raindrop. When the light leaves the raindrop, the light speeds up and bends again (refraction). It is the two refractions, that are not parallel, that cause the light to break up into a spectrum of colors.    Read more »
