CATALYSTS. "Clouds are a very special subset of the atmosphere because they present substantial amounts of condensed-phase water (liquid or solid) that can dissolve gases that would otherwise be present in the gas phase, and, as a consequence of condensed-phase reactions, permit reactions to occur that would not otherwise occur or would be much slower. In this sense "clouds may be considered to serve as catalysts of atmospheric reactions." https://lnkd.in/dHZs9ca View in LinkedIn

SUPERCOOLING. "Water droplets commonly remain as liquid water and do not freeze, even well below 0 °C (32 °F), because of the high surface tension of each microdroplet, which prevents them from expanding to form larger ice crystals. Without ice nuclei supercooled water droplets can exist down to about −40 °C (−40 °F), at which point they will spontaneously freeze." https://lnkd.in/dYECyJe View in LinkedIn

WHY CLOUDS DON'T FALL. "Upward vertical motions, or updrafts, in the atmosphere also contribute to the floating appearance of clouds by offsetting the small fall velocities of their constituent particles. Clouds generally form, survive and grow in air that is moving upward. Even a large droplet having a radius of 100 microns has a fall velocity of only about 27 centimeters per second (cm/s). And because ice crystals have more irregular shapes, their fall velocities are relatively smaller." http://www.scientificamerican.com/article/why-do-clouds-float-when/ View in LinkedIn

ASPERITAS, NEW CLOUD SYSTEM ADDED. "Since 2008, we have argued that this dramatic and distinctive cloud formation deserves a classification of its own. Now The World Meteorological Organisation have announced that they’re going to be making it the first new cloud classification since 1951." https://lnkd.in/dHirZbh View in LinkedIn
