How much does snow cover affect temperatures? Does snow reflect enough sunlight that it makes it colder?

Answered by John Hinsberger Meteorologist, National Weather Service-Pocatello, ID Office Daytime TemperaturesThe amount of incoming radiation from the sun that gets reflected back into space is known as albedo. Higher albedo means more of that radiation gets reflected back. Thus, less radiation can be absorbed by the surface, so temperature is affected. One of the…

Due to the fluctuations of the Earth’s temperature over time, who is to say that we aren’t currently living at the Earth’s natural temperature?

Question Answered by NOAA, Air Resources Laboratory, Field Research Division, Idaho Falls, ID The Earth’s climate does vary over time due to factors such as the movement of continents, large-scale volcanic activity, changes in the Earth’s orbit, and variations in the Sun’s energy output. Because of these changing factors, there is not one fixed temperature…

What makes a foggy day?

Answered by Nicole Peterson, Meteorologist, National Weather Service-Pocatello Office Fog is simply a cloud, but on the ground. In order for fog to form, there needs to be moisture in the air. Fog typically forms overnight when the air near the ground cools, and disappears in the morning when the sun warms up the air.…

We are currently studying clouds and rain. We were wondering what percentage of a cloud is actually water and what percentage of a rain cloud is dust and or other things?

Answered by Dennis Finn, Research Meteorologist, NOAA, Idaho Falls Most water in the atmosphere is in the form of water vapor, a gas. Warm air holds more water vapor than cold air. For a climate like Idaho Falls, water vapor content is typically about 0.4-0.5% in the summer and less than half of that during…
