How do clouds affect the Earth’s albedo?
Cloud albedo, along with the greenhouse effect of clouds, strongly influence the Earth’s energy budget.
Thick clouds (such as stratocumulus) reflect a large amount of incoming solar radiation, meaning they have a high albedo.
Thin clouds (such as Cirrus) tend to transmit most solar radiation, so have low albedo..
Can cloud seeding cause thunder and lightning?
Cloud seeding has been subsequently used to enhance precipitation, dissipate fog, modify hurricanes, and decrease lightning and hail in thunderstorms. Cloud seeding can occur naturally but is more often done by humans.
What’s a precipitation?
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. … This process is typically active when freezing rain occurs.
What is the formula for silver iodide?
Can man make it rain?
Cloud seeding is when humans try to modify the weather by targeting certain areas within clouds, with the goal of increasing rainfall, mitigating the potential damage from hail and clearing fog, according to the American Meteorological Society.
Does it ever rain in Dubai?
Rainfall in Dubai is infrequent and does not last for a long period. It mostly rains during the winter period between December and March in the form of short downpours and an occasional thunderstorm. On average, rain falls only 25 days a year.
Is silver iodide toxic?
Numerous controlled laboratory studies have shown that silver, silver nitrate and even silver iodide when added to laboratory aquariums, even at trace levels, can be toxic to some fish and other aquatic life when exposed over long time periods; the toxicity is related to specific compounds, concentrations and other …
How does cloud seeding affect the environment?
Cloud seeding involves putting particles, gasses or chemicals like silver iodide, dry ice or SO2… [+] The changes can increase the amount of heat radiated back into space and help cool a warming world.
Does the US government seed clouds?
WASHINGTON, July 2—The United States has been secretly seeding clouds over North Vi etnam, Laos and South Viet nam to increase and control the rainfall for military purposes.
Who invented rain?
Vincent J. SchaeferVincent J. Schaefer, a self-taught chemist who invented cloud “seeding” and created the first artificially induced snow and rainfall, died on Sunday at a hospital in Schenectady, N.Y. He was 87 and lived in Rotterdam, N.Y. Mr.
Why is silver iodide yellow?
The compound is a bright yellow solid, but samples almost always contain impurities of metallic silver that give a gray coloration. The silver contamination arises because AgI is highly photosensitive. … Silver iodide is also used as an antiseptic and in cloud seeding.
Which clouds can be chosen for seeding?
In mid-latitude clouds, the usual seeding strategy has been based upon the vapor pressure being lower over water than over ice. When ice particles form in supercooled clouds, they grow at the expense of liquid droplets and become heavy enough to fall as rain from clouds that otherwise would produce none.
Who invented cloud seeding?
Vincent SchaeferVincent Schaefer, a self-taught chemist who invented cloud seeding and created the first artificially induced snow and rainfall, died Sunday in Schenectady, N.Y. He was 87 and lived in Rotterdam, N.Y. Mr. Schaefer drew worldwide attention with his 1946 experiments for General Electric Co.
What is artificial rainfall?
Rainmaking, also known as artificial precipitation, artificial rainfall and pluviculture, is the act of attempting to artificially induce or increase precipitation, usually to stave off drought or the wider global warming.
Where did cloud seeding start?
Cloud seeding began in France during the 1950s with the intent of reducing hail damage to crops.
What are the dangers of cloud seeding?
Silver iodide, the material used in cloud seeding, is toxic to aquatic life. So precipitation from seeded clouds can harm the environment. In response to these concerns, scientists have tested nontoxic replacements for silver iodide. They have found calcium chloride to be effective.
How do clouds rain?
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. … Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
How do you stop rain from falling?
Here’s a DIY guide to cloud seeding.Step 1: Get an airplane.Step 2: Fly into clouds.Step 3: Release salt into the air.Step 4: Aim for the turbulence.Step 5: Repeat.
How do you dissolve silver iodide?
Some results are now given which show that, whereas silver iodide is practically insoluble in pure acetone, it is easily soluble in solutions of alkali iodide in acetone-more than 3 g. of silver iodide being soluble in 50 c.c of an N/10- sodium iodide solution in acetone.
Is cloud seeding still done?
Today California, Idaho, Nevada, Utah and Wyoming have winter cloud seeding programs, and Texas and North Dakota have summer programs, which aim to increase rain and decrease hail. Cloud seeding machines are nothing like the “snow guns” used to blast water over ski slopes.
Can we make it rain?
Farmers have long wished they could control the rain, and now weather manipulation can do just that. Cloud seeding, the most common way to modify weather, involves shooting silver iodide or other chemicals into clouds to encourage precipitation. In other words, a silver bullet can make it rain.
