Snowflakes swirling in turbulent air as they
<p>In Physics of Fluids, researchers from the University of Utah report snowflake accelerations in atmospheric turbulence. Using a device they invented that employs a laser light sheet, they gathered information about snowflake mass, size, and density and found that snowflake accelerations follow an exponential frequency distribution with an exponent of three halves. In analyzing their data, they also discovered that fluctuations in the terminal velocity frequency distribution followed the same pattern.</p>
