These extra-large drops usually end up splitting into two smaller droplets.
Very large rain drops (larger than 4.5 millimeters (0.177 inches)) have a huge indent and look more like a parachute. They look more like kidney beans when falling. Larger raindrops (two to three millimeters (0.078-0.118 inches) across) are also round, but with a small indent on their bottom side. In fact, smaller raindrops (ones that are approximately one millimeter (0.039 inches) across) are almost perfectly spherical. This helps water droplets gather together and become large enough to fall to the earth.Ī common misconception is that when raindrops fall, they have a teardrop shape. These particles, called “condensation nuclei,” provide a surface for water vapor to condense upon. Particles of dust or smoke in the atmosphere are essential for precipitation. As the snowflakes fall through warmer air, they become raindrops. Most rain actually begins as snow high in the clouds. These ice crystals then fall to the earth as snow, hail, or rain, depending on the temperature within the cloud and at Earth’s surface. If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice. When the drops are heavy enough, they fall to the earth. Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle.
It comes in many forms, like rain, sleet, and snow.

Isabella Fertel, USA TODAY, Nathan Cormier While dust storms are becoming more prevalent in the Southwest, other regions will likely experience fewer dust storms as overall precipitation continues to increase. Nouran Salahieh, CNN, Radar technology has a broad range of uses, including tracking weather and precipitation, monitoring airspace for aircraft and airborne weapons, tracking ships at sea and calculating the speed of moving objects. Shepard Price, San Antonio Express-News, The region has also seen a lack of precipitation which may have contributed to the extreme fire conditions in Alberta, drying out land and making fires more difficult to contain, CNN Meteorologist Robert Shackelford said. Maggie Shipstead Anthony Cotsifas, New York Times, Tuesday is expected to see thunderstorms throughout the day, with winds as high as 20 miles per hour and the chance of precipitation at 60 percent. Tony Reyes, Arkansas Online, The storms also proved how vulnerable the desert’s tiniest denizens are to precipitation.
