They’ve been carried by truck into supercell thunderstorms, flown on aircraft into hurricanes, and sliced and diced the atmosphere in myriad ways. Where are research radars headed next, and where will they take science and society?

As a step toward meeting the goal of providing earlier warnings, NCAR scientists and their colleagues are examining what enables poorly organized clusters of thunderstorms to develop into tropical storms and hurricanes.

Satellite images have revealed at least three dramatic eye-like features not far off the U.S. Atlantic and Pacific coasts over the last several weeks. While these can look startlingly like the eyes of hurricanes, they’re not quite the same thing.

Much of the United States has felt winter’s bite this week, with fresh but frigid cold to the east and a weeks-long spell of stagnant, polluted chill to the west.

New research points to gravity waves, which ripple unseen through the atmosphere, as the culprit in many cases of clear-air turbulence. If those waves can be forecast, the research suggests that planes in many cases could be rerouted around them.
