(Reuters) - as tropical storm and become a hurricane in the gulf of Mexico this week, before its path through the Caribbean, American scientists are testing new experimental weather spy tools - a pilotless, Marine robots the size of the surfing board, in the sea level can collect storm data.
A in Miami of America's national oceanic and atmospheric administration (NOAA) research laboratory sent to the ocean waters to about 100 miles north of Puerto Rico last week's "wave glider", named alex underwater stable a floating platform sensor, and try to intercept Isaac.
Alan leonardi, NOAA Atlantic ocean and meteorological laboratory in Miami vice director said: "Isaac don't really right after a barrel in it, the storm over the southern island front steering north and as a category 1 hurricane in New Orleans on nearby.
"But Isaac size storm and wave glider can collect data peripheral rainband, we can not at the helm of the storm, but we didn't get good data."
A few days later, the scientists made the second time to see Isaac, from another wave glider - named G2 - in a single task in the gulf's oil and natural gas.
Isaac's eyes, through G2 almost 60 miles east, so it can collect valuable ocean data, including water temperature sharply declining evidence, "this shows that and from the gulf thermal vacuum," according to its manufacturer, liquid robot, headquartered in sunny California Wells city,.
A Bill Vass, CEO of liquid robot, grew up in Louisiana, is a senior hurricane. His grandparents in 1969, died in the hurricane Camille and his family lost family katrina.
Close contact
"We are very proud, it is able to survive task," battle 85 miles per hour sustained winds, gust of up to 120 miles, "he said," hope wave glider will allow us to better predict the severity of degree and risk, everyone in the gulf coast region's future. "
Another robot ship, emergency comprehensive rescue hang rope, Emily, test will be this week in California in the Pacific Ocean, from Justyna Nicinska, project manager for NOAA weather in situ deployment optimization method.
The builder, Hydronalix, headquartered in Arizona Green Valley, Emily introduced in 2010 robots lifeguard. NOAA, manufacturers equipped with five feet five inches (1.65 metres) of ship and storm data collection sensor.
, NOAA bought 10 EMILYs at $30000 last spring, Nicinska said. The researchers said they plan to send a by the 2012 hurricane season for the end of a tropical storm.
These two kinds of waves glider and, EMILY can measure a tropical storm surface air temperature, cold, air pressure, the actual wind speed, relative wind speed, wind, ocean temperature and the salinity of the water, the researchers said.
The two sides will is cheaper than C - 130 hurricane hunters flight NOAA's research ship price of $10000 to $20000 operation, Leo beenhakker nall dean said.
The tiny boat will also be used in other NOAA project Marine resources, fishery, archaeology, image and bottom topography, the researchers said.
But meteorology hope plugging process storm prediction model and data, better prediction, tropical storm strengthen for hurricane, the researchers said.
Rules, NOAA ocean and meteorological laboratory spokesman said: "we are trying to understand what happened, it happened energy transfer between the ocean and cover the hurricane in the ocean surface, erica.
"Heat energy into kinetic energy drive of the storm, it from the warm water, them through," she said. "This is why hurricane death, when they walk on land or cold water."
The independent, military version
Wave glider is so strong and durable, it can stay at sea, a year's time to rely on renewable energy technology, conversion wave motion into energy for propulsion.
From the company's California office of satellite solar panels on the power supply circuit board of communication and sensor equipment, it can carry out pilot.
The robot has been used in ocean research scientists from the coast California monitoring great white shark. Military version, is called "shark" also be adapted to information, communication and monitoring action.
"The defense department said:" is our big customers, value-added services.
Leo beenhakker nall dean said, his NOAA laboratory are and builders have several preparation in the 2013 hurricane season. They will be placed in a line of the east of the leeward islands approximation of tropical storm path, he said.
"This is what we call the fence," he said. "The dream, there are six or twelve, all of these are the car rolled over storm."
