Abstract
The behavior of hygroscopic particles in the atmosphere under various humidity conditions has long been of interest to the field of atmospheric science. These particles absorb water vapor from the atmosphere and dissolve into droplets at high humidities. The condensation process is simple and well understood. However, when the humidity is decreased to a level lower than the humidity at which the droplets are formed, the droplets do not readily give up all the water until a much lower humidity condition is reached. Often a long waiting time is required. The mechanism of this process is closely related to the nucleation process and it has caused much confusion in the past. This study was undertaken to reveal some of the behavior of solution droplets in this region.
