abstract = "Cloud microphysical data obtained from aircraft measurements
during the GoAmazon2014/5 campaign were analyzed to examine the
differences in cloud microphysical properties and relationships
between the wet and dry seasons and their implications on cloud
microphysical processes. Basically, the distinct differences in
cloud microphysical properties between the wet and dry seasons
were considered to be due to higher concentration of aerosols and
their larger sizes in the dry season, leading to higher droplet
concentration. Analyses of cloud microphysical relationships and
mixing diagrams strongly suggest homogeneous mixing for most cloud
segments in both the wet and dry seasons: diluted cloud parcels
with smaller liquid water content (L) and lower droplet
concentration (N) generally had smaller mean volume of cloud
droplets (V). However, in the dry season some cloud segments
included cloud parcels that had high N of small cloud droplets,
which led to a low correlation between N and V and also between N
and L. These features are speculated to be due to secondary
activation of cloud droplets from the cloud condensation nuclei in
the entrained air, which seemed more likely to occur in the dry
season due to more favorable conditions for such a process,
including larger sizes of entrained aerosols, higher fluctuation
of vertical velocity and lager turbulent dissipation rate.",
