Weather folklore has probably been around as long as humans have been able to communicate verbally. Is there any truth to these, or are they just part of human myths and legends? Here, we will classify some of the weather folklore as truth or myth. “Red sky at night, sailor’s delight; red sky in the morning, sailors … Read more
Snow is a precipitation type that results from the build-up of ice deposition upon condensation nuclei. The snowflake size is amplified as ice crystals join together as the crystals move in the wind. A common theme in ice crystal development is the 6-sized structure of the ice crystals. The chemical bonding of ice molecules produces … Read more

The evolution of broadcast meteorology goes hand in hand with scientific advances and the method that it is communicated to the consumer. Timeline of broadcast meteorology (1915-1982) The evolution of broadcast meteorology has worked hand in hand with advances in technology. This is true both with the scientific advances of meteorology itself, and the way that … Read more
The snow-to-liquid equivalent is the amount of liquid precipitation that is produced after melting snow. The temperature profile of the troposphere and the surface temperature are important factors that determine this value. The “average” snow-to-liquid ratio is 10:1. This is saying that if 10 inches of snow fell and that snow was melted it would … Read more
