__** Making It Rain - Seeding Your Clouds (by Noah A., Dylan S., and Sherman S.) **__

=How "Seeding" Works (by Zach S.)= Cloud seeding helps keeps it raining. How it works is they get tiny particles called ice nuclei. They freeze water so it helps keep things cold. So it doesn't drop the rain. They can also add silver iodine to keep it cold in the cloud.

=The Theoretical Use of Seeding (by Dylan S.)=

Use in War
 The United States Navy and Air Force have joined with the University of Alaska, Fairbanks, to build a prototype for a ground based weapon system located in the country of Alaska.The individuals who are demanding answers about HAARP are all around As well as bushers in Alaska. They include a physician in Finland a scientist in Holland an anti nuclear protester in Australia independent physicists in the United States a grandmother in Canada, and countless others. There all around having questions about haarp. What it will do what it can do and why do we need it. HAARP

The Haarp Lazer is always questioned if it will be used for war. It’s a cheaper more efficient way to kill of a bunch of people wouldn't it. No bombs. No man power. Just a lazier and a bunch of rain! The conspiracy of the weapon is that over time it could replace the nuke.  "The lazer Boils the Upper Atmosphere. Then HAARP will zap the upper atmosphere with a focused lazer and steerable electromagnetic beam. It is an advanced model of an "ionospheric heater." (The ionosphere is the electrically-charged sphere surrounding Earth's upper atmosphere. It ranges between 40 to 60 miles above the surface of the Earth.)” Here is a video that shows the process of the [|HAARP Laser]. (2) (5)

Water Sources
Taken from en.wikipedia.org/wiki/Water_resources <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">We couldn't shake the mental picture of a gardener in the sky, digging little holes in the clouds and dropping in seeds, but we were pretty sure that wasn't how cloud seeding worked. We set out to learn more by doing a little rain dance, then typing "﻿<span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;">cloud seeding ﻿" into the Yahoo! search box. Here's what we learned.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">"Cloud seeding is a form of <span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;">weather modification <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">. It can be used to disperse fog, suppress hail, or control winds, but is most often used to increase precipitation. In order to understand the process, however, a basic understanding of clouds and how ﻿<span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; vertical-align: baseline;">precipitation ﻿<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> is formed is needed.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">"As warm air rises from the Earth, it begins to cool and forms tiny droplets of water that condense into cloud droplets. Cloud droplets are formed around particles of dust, salt, or soil (called <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-weight: normal; text-decoration: none; vertical-align: baseline;">//cloud condensation nuclei// <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">) that are always present in the atmosphere. These cloud droplets group together into clouds, which can form precipitation in one of two ways. In warm temperatures, the droplets in the clouds merge with many other droplets and become heavy enough to fall to the Earth as rain. (It takes millions of cloud droplets to form a single raindrop.) In colder temperatures, the droplets of water form ice crystals. Other droplets freeze onto these ice crystals, which grow larger and heavier until they fall to the ground as rain, snow, or hail. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Cloud seeding is actually a very complex process. In the simplest terms, it introduces other particles into a cloud to serve as cloud condensation nuclei and aid in the formation of precipitation. There are three types of cloud seeding: static mode, dynamic mode, and hygroscopic seeding.

<span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;">"Static mode <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> cloud seeding seeks to increase rainfall by adding ice crystals (usually in the form of silver iodide or dry ice) to cold clouds. <span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;">[|Dynamic mode] <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"> cloud seeding increases rainfall by enhancing "vertical air currents in clouds and thereby vertically process more water through the clouds." Basically, in this method of seeding, a much larger number of ice crystals are added to the cloud than in the static mode. In ﻿<span style="background-color: transparent; color: #000099; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; vertical-align: baseline;">hygroscopic seeding ﻿<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 11pt; font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">, salt crystals are released into a cloud. These particles grow until they are large enough to cause precipitation to form.

Many question the validity of the results, since they are difficult to prove. Others feel that science shouldn't interfere with nature. Still others claim that increasing rain in one area decreases it in another, in effect, "stealing" rain from other lands that may be in need. Many states have also passed legislation that attempts to regulate cloud seeding and other forms of weather modification." (4)

=The Use of Seeding Today=

Who Decides (by Noah A.)
<span style="background-color: #ffffff; color: #000000; font-family: Arial,Helvetica,sans-serif; font-style: normal; font-weight: normal; vertical-align: baseline;">The local weather station decides when and where to cloud seed depending on the facts and data on the weather.(1)

Who Pays (by Zach S.)
<span style="background-color: #ffffff; color: #000000; font-family: Arial,Helvetica,sans-serif; font-style: normal; font-weight: normal; vertical-align: baseline;">The people who pay for cloud seeding is us. They use our tax money to pay for the chemicals to cloud seed. (1)

Real World Examples (by Zach S).
Cloud seeding is widely used in modern day. It is used either to prevent large hail storm, help a reagion out when they are in a drought season, or a ski reasort so there will but lots of snow. seeding the clouds is used in many different ways.

"In the United States, cloud seeding is used to increase precipitation in areas experiencing drought, to reduce the size of hailstones that form in thunderstorms, and to reduce the amount of [|fog] in and around airports. Cloud seeding is also occasionally used by major ski resorts to induce snowfall. Eleven western states and one Canadian province (Alberta) have ongoing weather modification operational programs. In January 2006, an $8.8 million cloud seeding project began in Wyoming to examine the effects of cloud seeding on snowfall over Wyoming's Medicine Bow, Sierra Madre, and Wind River mountain ranges."
