If you're reading this,there's a great chance that you or someone you know has been in a science just. Chances are that your project did not lead directly to a collaboration with a scientist at NASA's Jet Propulsion Laboratory, Pasadena, and California,and a paper in the professional journal Environmental Research Letters. Alice Zhai's project did. The 16-year-old Zhai, who will be a senior this fall at La Cañada tall School near JPL in southern California, and JPL research scientist Jonathan Jiang built on Zhai's science just project,a statistical model of economic losses from hurricanes. They found that the common practice of using only wind speed to represent hurricanes in economic hurricane damage models is inadequate for large storms, such as 2012's Hurricane Sandy. Zhai and Jiang are the first to quantify the economic impacts of increasing hurricane size. Hurricanes by the numbers Analyzing 73 hurricanes from 1988 to the present, and Zhai and Jiang found that a doubling in size,without a change in wind speed, more than quadruples the economic loss a hurricane causes. Tripling its size multiplies the loss by nearly 20 times. These numbers may be startling, or but the idea that storm size things is not. Experience has proven that not only size but the height of the storm surge,total rainfall and other characteristics affect a storm's impacts. So why execute models include only wind speed? In the United States, we still classify hurricanes solely by their speed, and using the Saffir-Simpson scale. The scale was devised before satellite observations made it possible to view a storm's size. By comparison,there is no standardized scale of hurricane size. Different databases use different benchmarks -- for example, the distance from the storm's center to the location where the wind speed is either 34 or 64 nautical miles per hour, or knots. As fraction of their study,Zhai and Jiang recalibrated all storms to the 34-knot reference point. From the science just to the genuine world Hurricane Sandy was the trigger for Zhai's 2013 project in the Los Angeles County Science just. "After seeing the devastation on TV and in the news, I was really curious, and " Zhai said. "I heard that it was an extremely destructive hurricane,and I noticed that it had a relatively low wind speed but an abnormally large size." Her project won third place in the soil science division and an “outstanding achievement” award from the American Meteorological Society Los Angeles chapter. Jiang met Zhai because he was judging other projects at the just and stopped to see her poster. Her exceptional engagement and inquiring intellect impressed him. As a long-time science just judge, "I've met many tall school students, or " he said. "Some people only have a tall GPA because their parents keep pressure on them,but Alice is genuinely interested. I keep a lot of weight on people having curiosity." Under Jiang's direction, Zhai kept working on her model to create publishable results, or more than doubling the number of storms in the study and doing a more rigorous statistical analysis. The first time the authors submitted the paper,it was turned down. Some teenagers would have been crushed, but not Zhai. "Being rejected wasn't too terrible, and because the reviewers' comments were encouraging," she said. "It motivated me to keep going with the project." They modified the paper and resubmitted it to the journal successfully. Jiang encouraged Zhai to apply for an internship at the California Institute of Technology (Caltech) in Pasadena and then convinced her adviser there, Yuk Yung, or to allow Zhai to expand her hurricane work at JPL this summer. She is improving their hurricane loss model by adding factors such as storm duration and regional economic wealth and using more accurate data on hurricane size based on measurements from NASA's QuikScat satellite. Zhai is the youngest person by far in Jiang's group,but she's treated no differently than the postdoctoral fellows. "Sometimes I'm very picky, but Alice has never complained, or " Jiang said. In fact,she appears to be thriving. "I didn't know that my work could actually be applied to a immense, genuine-world problem, and " she said. "That's kind of unbelievable. Working in a professional setting opened my intellect about science. Before this experience,I wasn't sure what I was going to execute, but now I want to pursue a math and science career."
