I had to make a decision.\u201d<\/span><\/p><p><span style=\"font-weight: 400;\">Bluestein and his team of radar scientists made the call to board a plane to New York and then drive their radar truck to Massachusetts to do something that had never been successfully done before: study large snowstorms with their radar on the ground while NASA planes collected data from the skies.<\/span><\/p><p><span style=\"font-weight: 400;\">The research is part of NASA\u2019s <a href=\"https:\/\/espo.nasa.gov\/impacts\/content\/IMPACTS\">IMPACTS program<\/a>, which stands for \u201cInvestigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms.\u201d In the program, NASA flies a suite of remote sensing planes into snowstorms to understand how snow particles work across snowbands, and how snowbands form and evolve. The hope for the data collected is to significantly advance the ability to predict snowstorm characteristics.<\/span><\/p><p><span style=\"font-weight: 400;\">Bluestein and his team made up the ground crew for data collection. Their radar truck, which had been parked at the wharf at Plymouth Harbor the night before, was underwater from the high tide. With 70-mile-an-hour blizzard winds blowing around them, they waited until the tide went down, got in the truck and began over nine hours of data collection.<\/span><\/p>\n<blockquote class=\"twitter-tweet\">\n<p dir=\"ltr\" lang=\"en\">You know it&#8217;s an epic storm when legendary research meteorologist Dr. Howie Bluestein from <a href=\"https:\/\/twitter.com\/UofOklahoma?ref_src=twsrc%5Etfw\">@UofOklahoma<\/a> shows up with <a href=\"https:\/\/twitter.com\/raxpol?ref_src=twsrc%5Etfw\">@raxpol<\/a> and weather radar expert Dr. David Schvartzman.<br \/>\nThey were observing the <a href=\"https:\/\/twitter.com\/hashtag\/Blizzard?src=hash&ref_src=twsrc%5Etfw\">#Blizzard<\/a> and supporting the NASA <a href=\"https:\/\/twitter.com\/SnowIMPACTS?ref_src=twsrc%5Etfw\">@SnowIMPACTS<\/a> campaign.<a href=\"https:\/\/twitter.com\/OUARRC?ref_src=twsrc%5Etfw\">@OUARRC<\/a><a href=\"https:\/\/twitter.com\/ousom?ref_src=twsrc%5Etfw\">@ousom<\/a> <a href=\"https:\/\/t.co\/DOEFh3Ttg0\">pic.twitter.com\/DOEFh3Ttg0<\/a><\/p><p>\u2014 Mike Seidel (@mikeseidel) <a href=\"https:\/\/twitter.com\/mikeseidel\/status\/1487576180102512644?ref_src=twsrc%5Etfw\">January 29, 2022<\/a><\/p><\/blockquote><p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p><p><span style=\"font-weight: 400;\">NASA\u2019s P-3 plane flew above the researchers, collecting data about the types of cloud particles and precipitation particles. Another plane, an ER-2 model, was prevented from taking off in North Carolina until the strong crosswinds died down. By the time it arrived, the snow was ending. Regardless, Bluestein said the data collected from the P-3 and his ground team is \u201cquite valuable.\u201d<\/span><\/p><p><span style=\"font-weight: 400;\">The January event wasn\u2019t NASA\u2019s first field program, but it was the first nor\u2019easter of the program, and it was the first time Bluestein\u2019s team had been involved.<\/span><\/p><p><span style=\"font-weight: 400;\">\u201c[NASA had] never even got a big storm like this,\u201d Bluestein said. \u201cSo it\u2019s beginner\u2019s luck for me.\u201d<\/span><\/p><p><span style=\"font-weight: 400;\">The RaXPol system, maintained by the Advanced Radar Research Center (ARRC) at OU, usually operates more locally, probing severe thunderstorms and tornadoes. It sends polarized beams of radiation, one vertically polarized and one horizontally polarized, to the precipitation, which \u201cscatters\u201d the radiation back to the radar. The RaXPol measures the cross section of precipitation particles, and based on the amount of vertical radiation relative to horizontal radiation, scientists can tell what kinds of particles are in the air \u2014 large and small water droplets, ice, hail and more.<\/span><\/p><p><span style=\"font-weight: 400;\">The data from the ground are combined with data collected from the NASA plane, which gives researchers a more complete picture of what\u2019s happening during a snowstorm.<\/span><\/p><p><span style=\"font-weight: 400;\">\u201cWe\u2019re trying to learn: under what circumstances can you get heavy snow? Under what circumstances [can] we get not-so-heavy snow? Under what circumstances will you get different types of snow crystals?\u201d Bluestein said. \u201cSo you kind of attack it with a lot of instruments that measure different things.\u201d<\/span><\/p><p><span style=\"font-weight: 400;\">Bluestein said this grant-funded initiative from NASA only covers the field program, so analyzing the data will take more funding and will be done in part by other researchers. He said sorting through the data could take six months, and it will probably be another 1-2 years before scientists can draw conclusions about it. Though storms on the East Coast and the Southern Plains are different, he said what the researchers learned about clouds in Massachusetts can be applied to storms in Oklahoma.<\/span><\/p><p><span style=\"font-weight: 400;\">As far as braving blizzard conditions again for another trip up to the East Coast, Bluestein said he\u2019s ready for whatever this winter throws at him. While he doesn\u2019t think another big East Coast snowstorm is likely this season, he said if it happens again, his team will be there.<\/span><\/p><p><span style=\"font-weight: 400;\">\u201cOtherwise, this was a once-in-a-lifetime experience, because no one\u2019s ever done this before with a storm of this magnitude with a radar like this,\u201d Bluestein said. \u201cSo this may be my one shot, but you never know.\u201d<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Howie Bluestein was waiting for the right storm.
