Laitin took advantage of his timeout from Harvard to work in cloud forest as part of a Global-Roots volunteer program in Monteverde, Costa Rica. Because it does not rain year-long in that area, it is considered a cloud, and not a rain, forest, Laitin explains...
Before VORTEX, scientists had a general idea of how tornadoes come to be. They knew, for example, that big twisters are most likely to be generated by what are termed supercell storms--towering cloud structures that sometimes top out at 65,000 ft. and concentrate energy in dangerous ways. Supercells typically form in spring as warm, moist air from the Gulf of Mexico flows north and pushes through colder, dryer layers of air. As it rises, this upwelling of warm air begins to cool, and the moisture it contains condenses first into cloud droplets and then into rain. At that...
Mesocyclones are the broad spinning cloud structures from which tightly coiled tornadoes seem to drop. What scientists are trying to find out is how one turns into the other...
Until VORTEX, the competing hypotheses about tornado formation could not be rigorously tested. The downdraft theory, for example, was bolstered by storm chasers' sightings. Observes Erik Rasmussen, field coordinator for VORTEX: "What storm chasers see first is a big dark cloud, then a bright spiral slicing into the base." The problem is that the flow of air within a big storm is so complex that what the eye sees cannot always be trusted. Hence the need for measurements...
...straightforward account of what these men did would have been enough in itself to make a compelling book. But the husband-and-wife team of Stanley Cloud and Lynne Olson (he's a former Washington bureau chief for TIME; she's a former correspondent for the Associated Press) is after something more ambitious with The Murrow Boys: Pioneers on the Front Lines of Broadcast Journalism (Houghton Mifflin; 445 pages; $27.95). The authors have given us a clear-eyed account of what happened to these luminaries as well as to broadcast journalism in the decades after World...
