Cloud seeding is a form of weather modification that aims to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air. en.wikipedia.org/wiki/Clo…
The Weather Channel admits to exaggerating the probability of rain. This is because if the correct low probability of precipitation is given, viewers may interpret the forecast as if there were no probability of rain, and then be upset if it does rain. en.wikipedia.org/wiki/Wet…
Antarctica is considered a desert, because the annual precipitation is 2-20 inches. en.wikipedia.org/wiki/Ant…
The technical term for precipitation is hydrometeors. glossary.ametsoc.org/wiki…
When a meteorologist gives a 'chance of precipitation' it's based on a calculation. I.E. if they are 50% confident that 80% of an area will receive rain, the chance of rain is 40%. srh.noaa.gov/ffc/?n=pop
Graupel is the official term for precipitation that lies between snow and hail. weather.about.com/od/g/g/…
Today I learned of Pyrocumulonimbus clouds that form above sources of heat, such as wildfires. These clouds form from condensing smoke and can cause precipitation, hail, lightning, even tornadoes. en.wikipedia.org/wiki/Pyr…
Today I learned of graupel, a type of frozen precipitation distinct from snow, hail, or sleet. en.wikipedia.org/wiki/Gra…
The different percentages of precipitation given by your weather station signifies what percentage of the viewing area will actually get precipitation feedback.weather.com/know…
Most civilian aircraft are fitted with "static dischargers" or "static wicks" which are long thin extensions fitted to the trailing end of an airplane's wings or stablizers. These wicks serve to dissipate precipitation static and help eliminate audio disturbances, weak radios, etc. flyingmag.com/technique/t…
The expression "desert island" has nothing to do with precipitation. It only reflects the presence of inhabitants. In the phrase "desert island," the adjective "desert" is meant to connote a "desolate and sparsely occupied or unoccupied area." en.wikipedia.org/wiki/Des…
A weatherman can not use 50% when describing the Chance of Precipitation (CoP) ec.gc.ca/meteo-weather/de…
Seattle receives less annual precipitation than New York, Houston, and several other US cities en.m.wikipedia.org/wiki/S…
By the process named concretion a rock can sort off grow another rock around it when buried by mineral precipitation. ww2.kqed.org/quest/2012/0…
Someone took over half a year's worth of forecasted temperature/precipitation data and compared it with the actual temp/rain on that day. Among other things, he found that over 11 days out, a forecast is worse than the average high by a 95% confidence margin. josh-rosenberg.com/2013/0…
Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds. en.wikipedia.org/wiki/Clo…
The "percent chance" precipitation on a weather forecast is not actually a chance, but a product of formation of precipitation and viewing area. weather.aol.com/2013/02/2…
There is a company outside of Bowman, ND that offers 'weather modification' services to increase precipitation and augment snowfall through a process called 'cloud seeding' weathermodification.com/
"Pineapple Express" is a non-technical term for a meteorological phenomenon characterized by a strong and persistent flow of atmospheric moisture and precipitation en.wikipedia.org/wiki/Pin…
In weather forecasts, the "Percentage of Precipitation" otherwise know as "Probability of Precipitation" (PoP) describes the chance of precipitation occurring at ANY point forecasters select in the area. Not just for that day the public checks. weather.gov/ffc/pop
A 50% chance of rain can occur in a forecast as it's raining. Probability of Precipitation is an average over a forecasted area. In one part of a forecasted area there can be a 100% chance of rain, and in another part of the same area there can be 0% - we are then told "50% chance of rain". metoffice.gov.uk/news/in-…
The Atacama Desert (Chile), the driest place on Earth, has some weather stations which have never recorded precipitation en.wikipedia.org/wiki/Ata…

Houston, New York, and D.C. receive more average anual precipitation than seattle. infoplease.com/ipa/A07621…
The Sahara is not actually the largest desert in the world. The largest is in fact Antarctica (with the Arctic in second). A desert is defined by extremely low levels of precipitation. en.wikipedia.org/wiki/Lis…
