..wake up to tomorrow, stick around for a while. the state's been dry for two years now, on what california does when the sky refuses to open up.

there's a lot of water in those storm clouds, but the problem is that the water is up there, not on the ground where it's needed. california's reservoirs tell the story, in that line that looks like a bathtub rith's where the water level used to be. just about four-inches so far this year, rainfall is the lowest it's been in california since it was first measured 164 years ago. part of the problem is what is in the clouds or really what is not in the clouds. here, for instance, at the top of the ski area over lake tahoe.
they don't have a lot of particles that water can form either droplets or ice chris calls.
if you want water you have to help those clouds. many areas are depend on cloud seeding to squeeze nor water and snow. cloud seeding increases the amount of water that comes out of storms. and studies have shown that around here, that percentages anywhere from ten to 20%. cloud seeding injects crystals into storm clouds either from a ground base generator or an airplane. it gives water something to grab on to to start forming a rain drop or freezing into snow. it takes about 15 minutes for the precipitation to occur, once you have seeded based on wind direction, and wind speed at the altitude where the storm is. they can pretty much predict where that wattser going to land and it is cheaper. it is extremely difficult to show any real serious and significance positive impacts. never the less, scientists believe it makes a big difference near lake tahoe. normally is provides anywhere between 15,000, and about 23,000-acre feet of water per year. an acre foot is an amount that covered an acre of surface. it requires storm clouds to have something to seed. it's tough to do in a drought year, where most days look like this. al jazeera, los angeles.
