Using a special setup that combined a bellows camera and a microscope, he captured the amazing shapes and patterns of snow crystals in great detail. Keith C. Heidorn explores Bentley’s life, showing how his curiosity and hard work helped reveal the hidden beauty of snow and made an important contribution to both science and photography.

Description
Scientists often need to know how much wind direction changes over a day, especially when studying air pollution. One way to measure this is the Consistency Index, which can be used with data recorded in degrees or compass directions. Researchers compare this Index with the standard deviation of wind direction. By doing this, they can set clear limits that help them decide whether the wind data is reliable enough to use in their studies.

This book explores everyday weather wonders like sundogs, halos, dust devils, snow pillars, lightning, rainbows, and more. Keith C.
