Lightning is created from the discharge of electric particles in the atmosphere and on the ground. As a thunderstorm moves it gathers positively…
Question answered by Jason RichMeteorologist, NOAA ARL Field Research Division Spring is typically windy as we transition from the cool season to the warm season. Uneven heating of the Earth’s surface creates differences in atmospheric pressure across the globe. When differences in the pressure exist, winds flow from the high pressure to the low pressure.…

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…
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…
Answered by Alana Jensen, INL ESER Program This is not simple question to answer because they are several factors that help determine how fast snow and ice will melt. This conditions are constantly changing and form kind of a tug-of-war in the melting process. The most obvious factor is temperature. If the air temperature is…
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.…
