We’ve been having a lot of wind this past week. What happens to make the wind speed faster than normal?

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.…

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.…

Why does lightning sometimes hit the ground and other times go from cloud to cloud?

Answered by Travis Wyatt, National Weather Service, Pocatello Office All lightning comes from thunderstorms. When a thunderstorm develops, electrical charges (either positive or negative) within the cloud separate. This creates two different electric fields between the top of the cloud and the base of the cloud. When these electric fields build up enough, there is…

What does an strong El Niño winter mean for Idaho?

Answered by Mike Huston, Meteorologist, National Weather Service Unusually warm sea surface temperatures across the tropical Pacific continue to support El Niño conditions and forecasters at the Climate Prediction Center unanimously favor the development of a “strong” El Niño which is expected to persist through the winter and gradually weaken during the spring of 2016. Across the United States, temperature and precipitation impacts…
