Is our recent cold snap a harbinger of things to come?
Our recent cold snap has brought the November average to just 0.5 degrees above normal through the first 17 days of November after a relatively warm October in Madison, where the average temperature was 5.9 degrees above normal. It is … Continue reading

What is La Niña and the impact on Wisconsin’s coming winter weather?
La Niña refers to a departure from normal in the sea-surface temperature across much of the eastern tropical Pacific Ocean.
The water temperatures off the west coast of South America are typically 60 to 70 degrees. During a La Niña these waters get as much as 7 degrees colder than normal. La Niña conditions recur every few years and last nine to 12 months, though some events have lingered for as many as two years. This cooling results from a strengthening of the winds over the tropical Pacific and its interaction with the underlying ocean waters. Continue reading

How is the Artic Sea ice situation?
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?
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 impact did Sputnik have on weather monitoring and predictions?
Sixty-four years ago the Soviet Union launched Sputnik, the first artificial satellite. This was not welcome news in the United States as it confirmed that the Soviets were well ahead of us in the development of rocket technology. In fact, … Continue reading
