How is the Artic Sea ice situation?

Posted on October 18, 2021 by WeatherGuys Editor

The sea ice cover in the Arctic Ocean is one of the key components of our climate system.

The brightness of the sea ice reflects more solar energy to space than open water. Global warming is amplified in the Arctic as the ice cover decreases. This is referred to as the ice-albedo feedback. Continue reading →

Why did two meteorologists receive the Nobel Prize?

Posted on October 11, 2021 by WeatherGuys Editor

It was with great excitement that we learned last week that the Nobel Prize in Physics was shared among three scientists who had each made “groundbreaking contributions to our understanding of complex systems.” Two of the three so awarded were meteorologists, professor Syukuro (Suki) Manabe of Princeton University and professor Klaus Hasselmann of the Max Planck Institute for Meteorology.

Together, they were cited for their work in “the physical modeling of Earth’s climate, quantifying variability and reliably predicting global warming.” Continue reading →

What is the ozone hole?

Posted on September 27, 2021 by WeatherGuys Editor

Ozone is a colorless gas made up of three oxygen atoms (chemically denoted as O3). It occurs naturally in small amounts in the upper atmosphere (the stratosphere), about 18 miles above the surface.

Ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it. Ozone is created when oxygen (O2), is split apart by ultraviolet energy emitted by the sun into single oxygen atoms. The single oxygen atoms can rejoin to make O2, or they can join with O2 molecules to make ozone. Continue reading →

When does autumn begin?

Posted on September 20, 2021 by WeatherGuys Editor

The changes are subtle but apparent to the keen observer at this time of year — the first changes of color on trees, the earlier sunset and the rapid temperature drop that follows.

Summer is ending and fall is taking its place. This fact is formalized at 2:20 p.m. Wednesday when the autumnal equinox occurs. Continue reading →

Why do tornadoes happen in hurricanes?

Posted on September 13, 2021 by WeatherGuys Editor

When hurricanes make landfall, they can spawn tornadoes.

The friction over land is much stronger than friction over water, where the hurricanes form. Frictional force quickly weakens the farther you get from the ground. Continue reading →
