Answer:
Correlated-dot motion
Explanation:
Motion perception is a process of inferring the direction of elements and the speed of the motion during a scene which is based on the visual or vestibular or proprioceptive inputs.
In the context, inferring the motion in a snowstorm by seeing which way the wind is blowing and by what percentage of the snowflakes are been moving in same direction is analogous to the correlated dot motion.
