As Hurricanes Approach, the Robotic Storm Chasers of the Future Are Ready | Popular Sci... - 0 views

  • Authorities like NOAA gather storm data from a few different sources--from aircraft circling the weather system from tens of thousands of feet, from stationary weather buoys scattered throughout the Gulf of Mexico, from Earth-orbiting satellites--giving scientists a great view of the area around the storm.
  • “Currently there are only two or three ways to get this kind of data,” Dr. Alan Leonardi, deputy director of NOAA’s Atlantic Oceanographic and Meteorological Laboratory, says. “First, you can have a storm serendipitously traverse over a buoy that happens to already be in the water, and that doesn’t happen as frequently as some might believe. Another would be to position a ship out there to collect this data, but that creates a dangerous situation for any crew that might be aboard the ship, so we’re not going to do that. The third--and we have done this--is to deploy instruments from aircraft in front of a storm that can collect data as the storm passes. We then go back in a ship and pick up those buoys--if they survive and don’t end up sinking.”
  • NOAA’s two robotic platforms are being developed independently of one another, yet their roles dovetail neatly. The Liquid Robotics Wave Glider platform is designed as a kind of storm monitoring sentry--like a weather buoy, but one that researchers can move at will. Wave Gliders harvest their propulsive energy from ocean waves themselves and power their onboard electronics with solar energy. This means they are not very fast--too slow to actually chase a storm in most cases--but they can remain at sea for months on end, waiting and watching.

  • With an operational life of ten days, EMILY can be dropped into the water ahead of a storm, navigate its way into the very center, and remain there, tracking the storm as it moves while streaming data all along the way.
  • the eyewall--the ring of powerful thunderheads that encircle the eye of the storm.
  • the agency already has one Wave Glider in the water north of Puerto Rico as a test-bed for the dozens NOAA hopes will follow. Isaac tracked south of Puerto Rico and missed the prototype, but the robot did manage to capture data from some intense weather along the outer bands of the system--the first of what NOAA hopes will be a new wealth of hurricane data produced by its robotic fleet.
  • Better hurricane prediction translates directly to lowered economic losses, better mitigation of property damage, and--as it goes without saying on the eve of Katrina’s anniversary--lives saved.

    As the 2012 hurricane season reaches full tilt, researchers at NOAA are hard at work hacking two different maritime robots that the agency hopes will become critical storm forecasting tools of the future. The first, Liquid Robotics' Wave Glider, is envisioned as a persistent surveillance platform, an army of mobile monitoring stations that will remain at sea for the duration of a hurricane season, waiting to swarm into the path of a developing storm. The second--Hydronalix's Emergency Integrated Life Saving Lanyard, or EMILY (a 2010 PopSci Best of What's New award winner)--will be capable of tracking the storm itself for days at a time, streaming continuous data directly from the center of the storm to researchers ashore.
