Precipitation (Water Falling from the Sky) There are many different types of precipitation —rain, snow, hail, and sleet for example—yet they all have a few things in common. The period used for computing the climatology is 1979-2000. Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. The temperature of the cloud and the air between the cloud and the ground create different kinds of precipitation. Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. The droplets that do land on the ground … all forms in which water falls to Earth from the atmosphere. (The reduction of cloud droplets to temperatures below the normal freezing point is termed supercooling.) White House climate czar John Kerry traveled to Iceland by private jet in 2019 to accept an environmental award and defended his transportation choice to a reporter at the time by calling it, “the only choice for somebody like me.” Kerry flew to Iceland in October, 2019 to receive the Arctic Circle award, an iceberg sculpture, for his leadership on climate issues and being “a consistent voice … Very large rain drops (larger than 4.5 millimeters (.177 inches)) have a huge indent and look more like a parachute.
