Did weather forecasting play a role in D-Day?
Last week was the 78th 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. More than three months before the invasion, a combined British and American forecasting team began rigorous forecast exercises designed to iron out the physical and logistical kinks of such a coordinated effort.

Immediately after World War II, it became fashionable to imagine technologies that might allow human beings to control the weather.
In fact, one goal advanced by influential scientists was actually to explode nuclear bombs in the right locations and in the right quantity so as to alter the weather in favorable ways. Such an enterprise would require accurate forecasts of the weather thought possible by using the brand new computer technology to make the millions of requisite calculations. Continue reading

Perhaps unsurprisingly to Madisonians, April snow is by no means unusual here in town. Thirty Madison Aprils — out of 84 — since 1939 have had at least one 1-inch snowfall event. Continue reading
Is mathematical pi used in meteorology?
The ratio of a circle’s circumference to its diameter is a constant value. The size of the circle does not matter; this ratio is always the same value and is called pi.
The existence of this constant was known by the Babylonians and the Egyptians dating back to at least 2000 B.C. The numerical value is represented by the Greek letter for p, or π. Continue reading
