The Golden State usually has clearly defined wet and dry seasons. In the summer, hardly any water falls and sunlight bathes the coast. When winter comes and much of the country lies under a frozen blanket, Californians await rainstorms that roll in on the jet stream from the Pacific to water their plants and fill their reservoirs. That atmospheric current is vital to the health of California. Without it, the state is vulnerable to crop failures, forest fires, and water scarcity. Researchers peg agricultural cost of the current drought at $2.2 billion and 17,000 seasonal and part time jobs--and that's just for 2014.
