Into the Eye Of Ivan

As the WP-3D makes its sixth pass through the tumult of the eyewall, Cione begins to look a little pale. "How many more are we going to make?" he groans. I too am savoring the calm as the plane traverses the eye. Ivan's is a big eye, some 40 miles across, and a mean-looking one too, occluded by glowering clouds. Jack Parrish, the senior NOAA scientist in charge, thinks some of these may be half-digested remnants of an earlier eyewall around which Ivan has regrouped. Big hurricanes sometimes form concentric eyewalls, he says, and that makes flying through them all the more unnerving.

Even under optimal conditions, gathering data by flying into hurricanes is never fun. Yet these gut-wrenching passes are extremely valuable. For with each one, Paul Chang, a NOAA researcher who works on remote sensing technology, amasses more information about how his instruments operate, and that information, he says, will allow him to calibrate similar instruments mounted on satellites. Someday he and his colleagues may be able to monitor the dynamic surface wind field in the vicinity of a hurricane at a comfortable remove.

At long last a loud whoosh announces the fall of the last dropwindsonde. Over the radio, Parrish's voice signals the end of the mission. By now, even Parrish is getting weary of the nine-hour flights that have been taking off daily for eight days running, ever since Ivan blew up into a hurricane, not far from St. Croix. Attacked by fierce winds and savage rains, NOAA's fleet of hurricane hunters (two WP-3Ds and a Gulfstream IV) is showing signs of stress as well. The protective coating on the stabilizer of the plane I'm riding in is beginning to erode, for example. And while it's not an immediate threat, it would be nice, everyone agrees, to have a little downtime to repair it.

This year, however, downtime has been hard to find. Following 25 relatively quiet years, 1995 marked the beginning of what many scientists believe could be a decades-long phase of hurricane hyperactivity. So far this year, 11 named storms have arisen in the Atlantic, and seven have hit the U.S.

And it's not over. Even as Ivan's tattered remnants saturated the Southeast with flooding rains, Jeanne was menacing the Dominican Republic, and a storm called Karl was gathering force in the Atlantic. NOAA's hurricane hunters are not going to get much rest just yet, it seems, and they may not until Nov. 30, when the all-too-memorable 2004 hurricane season finally recedes into history.
