The D-day landings: the fate of 2.5 million men, 3000 landing craft & the entire future of Europe depends on the right weather conditions on the English Channel on a single day. A team of Allied scientists is charged with agreeing on an accurate forecast five days in advance. But is it even possible to predict the weather so far ahead? & what is the relationship between predictability & turbulence, one of the last great mysteries of modern physics? Wallace Ryman has devised a system that comprehends all of this
- but he is a reclusive pacifist who stubbornly refuses to divulge his secrets. Henry Meadows, a young maths prodigy from the Met Office, is sent to Scotland to discover Ryman`s system & apply it to the Normandy landings. But turbulence proves more elusive than anyone could have imagined & events, like the weather, begin to spiral out of control.
