Web12 hours ago · The upper troposphere (UT) nucleation is thought to be responsible for at least one-third of the global cloud condensation nuclei. Although NH 3 was considered to be extremely rare in the UT, recent studies show that NH 3 is convected aloft, promoting H 2 SO 4-HNO 3-NH 3 rapid nucleation in the UT during the Asian monsoon. In this study, … WebJan 22, 2024 · The first step is to establish the physical chain of events that occurs when seeding material is introduced into a supercooled cloud. Once this is established, the next step is to determine the conditions under which these changes (due to seeding) occur and how often they might exist for a particular region.
WebAround 40 to 70% of global cloud condensation nuclei (CCN) ( 4 – 6) are thought to originate as nucleated particles, so the process has a major influence on the microphysical properties of clouds and the radiative balance of the global climate system. WebJan 11, 2024 · To form clouds and ultimately enable precipitation, tiny particles called aerosols are crucial. Sometimes, water condensates directly on an aerosol, which functions as cloud condensation nuclei. Other times aerosols will act as ice-nucleating particles (INPs), which means they are seeds for tiny ice crystals instead of water droplets.
