motion of a
particle traversing 3 unit - lengths.
«Probability density function,» a statistical representation of the likelihood of something
occurring at any point in time, was used to examine cloud properties, including vertical
motion, liquid and ice water content, and the conditions of cloud
particle growth, including how ice crystals grow at the expense of liquid droplets.
