Does precipitation need ice nuclei
A typical raindrop is about 2 mm in diameter, a typical cloud droplet is on the order of 0.02 mm, and a typical cloud condensation nucleus (aerosol) is on the order of 0.0001 mm or 0.1 µm or greater in diameter. The number of cloud condensation nuclei in the air can be measured at ranges between around 100 to 1000 per cm . The total mass of CCNs injected into the atmosphere has been estimated at 2×10 kg over a year's time. WebDec 9, 2024 · 7: Precipitation Processes. 6.9: 6.9. Review. Hydrometeors are liquid and ice particles that form in the atmosphere. Hydrometeor sizes range from small cloud droplets and ice crystals to large hailstones. Precipitation occurs when hydrometeors are large and heavy enough to fall to the Earth’s surface. Virga occurs when hydrometeors …
