Is warmer air ‘heavier’?
We are now in the heart of the baseball season and even the casual fans begin to tune in a bit more regularly to the summer game. One of the long-standing pieces of baseball wisdom suggests that the heat and humidity of oppressive summer heat waves render the air “heavy” and lead to a decrease in offensive power, particularly in home runs.
The veracity of this “wisdom” is testable. Continue reading
Did weather forecasting play a role in D-Day?
Wednesday was the 74th anniversary of the Allied invasion of Europe that began with the landings on the beaches at Normandy.
The combined land, air and sea assault of June 6, 1944, remains the largest such event in history. The success of the invasion was extraordinarily dependent on weather conditions. Continue reading
If we stopped emitting carbon dioxide right now, would Earth stop warming?
No. Objects, even the atmosphere, will warm as long as the energy gains exceed the energy losses to their environment.
When the energy gains balance the energy losses, the object’s temperature remains constant. If the carbon dioxide levels were to suddenly remain constant, the atmosphere would continue to warm. Continue reading

Is this hot start to summer unusual?
Beginning on Saturday, Madison has experienced two straight days in May at or above 90 degrees for the first time since 1991 and for only the third time in nearly the last half-century (the others were in 1975 and 1978).
What’s more, the forecast is for temperatures to soar into the mid-90s again today and Tuesday which, if it happens, would be the first time since at least 1971 (and perhaps in its history) that Madison has had four consecutive May days at or above 90. Continue reading
Will the recent volcanic eruptions in Hawaii lead to a change in global weather patterns?
While the recent Hawaiian eruptions are impacting the weather and air quality of the immediate area, they are not likely to have a global impact nor to affect Wisconsin’s weather.
The reason is that the ash cloud debris, while reaching 30,000 feet, has remained in the troposphere, the layer where local weather occurs. To have a global impact, the volcano must eject debris into the stratosphere. There it can last for a couple of years and spread over the entire globe. By the ash reaching only into the troposphere, it can stay airborne for no more than a week due to precipitation processes, wind and gravity. Continue reading
