What is ice fog?

Meteorologist Brett Collar breaks down a weather phenomena called Ice

Here in the Miami Valley we see all kinds of weather phenomena, including freezing fog and ice fog. While the two have similar dynamics, they do vary a bit.

Fog that turns to ice upon contact with a solid surface that has a temperature of 32 degrees Fahrenheit or less is known as freezing fog. This often occurs on elevated surfaces such as trees, power lines, bridges and overpasses. 

Ice fog is fog that freezes mid-air, simply because temperatures are so cold. The fog is not able to live long enough as water vapor and touch a solid surface before it crystallizes. 

Ice fog is not something that is often seen, and it only occurs while conditions are very cold and winds are light. The ice fog is noticed as a shimmering fog, often times referred to as frost flakes.

Weather-related events make Google top trending searches for 2017

Published: Thursday, December 14, 2017 @ 6:11 AM

Major hurricanes and a solar eclipse topped Googles 2017 list of trending searches.

Google released their top searched items for 2017 and three of the searches were weather related, according to Storm Center 7 Meteorologist Kirstie Zontini.

Here’s the list:

1. Hurricane Irma

Hurricane Irma was Google's the most searched topic in 2017. Irma was the first category 5 hurricane of the 2017 Atlantic hurricane season. The powerful hurricane devastated Barbuda where it destroyed 95 percent of the island. Irma also moved to Florida where it made landfall twice, once in Cudjoe Island and again in Marco Island. Winds peaked for Irma at 185MPH.

4. Super Bowl 

5. Las Vegas Shooting 

6. Mayweather vs. McGregor Fight 

7. Solar Eclipse

The first coast to coast solar eclipse in almost a century was a sight to see...Safely of course. A solar eclipse occurs when the moon passes between the sun and the earth casting a shadow on the earth. The solar eclipse August 21 had a path of totality that went from Oregon to South Carolina. On April 8, 2024, Dayton will be in the path of totality.

8. Hurricane Harvey

Another one of the devastating hurricanes of the 2017 season. Texas and Louisiana will never forget Harvey. Hurricane Harvey was a major Category 4 storm which sat over south Texas and Louisiana for days dumping record breaking rain and creating catastrophic flooding. Harvey was the first major hurricane to make US landfall since 2005.
