PHOTO ESSAY: Behind-the-scenes moments as hail chasers learn about pounding and costly storms

MORTON, Texas (AP) — Even when Mother Nature turns nasty, the weather extremes carry a sense of awesome beauty. About 60 scientists this spring and early summer went straight into hailstorms to better understand what makes them tick and learn how to reduce the $10 billion in annual in damage they cause each year in the United States. When three Associated Press colleagues joined the scientists for several days, they found more than just hail, strong winds, rain and science in the storm. They found breathtaking sights and sounds to share. When there are dozens of scientists — many of them students — high-tech radar, weather balloons, hail collecting devices and storms that sometimes have tornadoes in them, someone has to make sure it all goes well and no one gets hurt. For the first few weeks of Project ICECHIP that someone was Victor Gensini, Northern Illinois University meteorology professor and one of the hail team's lead scientists. Gensini and his hand-picked students guided everyone like chess pieces via a computer program called Guru in his command vehicle. But he couldn't just sit back in the SUV and let others have the fun. He would drive close to the storm, not close enough to get the car damaged because unlike the Husky Hail Hunter he didn't have protective mesh hanging over the windshield. But he would get close enough to study, direct and just gaze in wonder at storms that would take over the horizon in the Texas panhandle and nearby Oklahoma and New Mexico. The clouds themselves tell the story of a roiling atmosphere. At times dark and dangerous, sometimes they are light with visible vertical stripes indicating downpours. And then a large bulging tornado can form and inspire awe and fear. There are small twisters that can also form and turn out just as dangerous. And finally if you are lucky at the end, there's a rainbow or two. One afternoon in the Texas panhandle, the hail chasing team could gaze out and see a double rainbow and a swirling twister that didn't quite reach the ground. The clouds aren't just beautiful above the vast plains. When they frame a building, such as the one sporting the Hollis Tigers mascot in Hollis, Texas, they combine to look menacing and stark. Two teams, the Red and the Black Teams, try to go ahead of the storm to see how it develops. They release wind balloons with instruments and GPS tracking that measure moisture, wind speed and direction. Inflating weather balloons is not a simple task. As gusty winds push, students scientists they have to inflate the balloon, tie it up, connect the instrument panel which is sealed in a disposable coffee cup with a lid on it. Then it's time to release the weather balloons. It's a two-person job with one holding the cup of instruments and the other the balloon. Releasing weather balloons isn't just letting them go. It's got to be done with some care — usually a 'one, two, three' and release — otherwise the instrument cup could slam into the balloon holder as an Associated Press reporter nearly found out the hard way. Once released, the balloons can fly as high as 60,000 feet or more. Or they can never quite get off the ground if there's a tiny hole in the balloon. There's also time to gawk as well as be scientists. Black Team members Evelynn Mantia and Olivena Carlisle, both of NIU, take photos of an approaching storm they have been monitoring. And once they finish, their job is to fall back a bit and then collect hail that has dropped. A storm hits, forcing one team to take cover The Red Team also releases weather balloons to get ahead of the storm and collect hail stones afterward. But the three students also get to go a bit into the storms. Ahead of the gathering storm, Ethan Mok and Wyatt Ficek release their balloon. In the first several days of the ICECHIP campaign, the Red Team earned a reputation for pushing the envelope. And on this late afternoon into early evening in New Mexico, the team, with Mok at the wheel, showed why. After releasing their balloons they went ahead into the storm as the skies darkened. The rain started coming down. Winds began to blow. They pulled over to take some pictures of the storm taking over the horizon. As they did, a semitruck sped down the road into the storm. Mok and team members laughed, saying the truck would have to turn around. The Red Team wasn't going to turn around. Photos taken, they drove off into the storm like the truck. The skies got even darker. Winds and rain intensified. Visibility out the windshield disappeared. Somewhat reluctantly, Mok finally pulled off the tiny road and waited. They watched the semitruck come back and try to flee the storm. They vehicle shook. They stared at weather radar and outside. Over the radio, Gensini had meteorology student Katie Wargowsky radio to them to get to safety. Mok quickly complied, trying to go south and around the storm and back to the chasers' hotel. The storm had other ideas. It overtook the Red Team. Hail was coming down. Wind was whipping. Visibility was gone. Wargowsky radioed for them to pull into a gas station for safety. Mok said he wished he could but the stretch of road was remote and there were no gas stations for cover. He had to barrel through, finally making it to a fast food drive-thru as reward.

Crushing it. What do you do with 4,000 hailstones that you collect while chasing storms?

Dozens of researchers are chasing driving and running into storms to collect fresh hail, getting their car bodies and their own bodies dented in the name of science. They hope these hailstones will reveal secrets about storms, damage, and maybe the air itself. But what do you do with nearly 4,000 melting ice balls? A lot. Researchers in the first-of-its-kind Project ICECHIP to study hail are measuring the hailstones, weighing them, slicing them, crushing them, chilling them, driving them across several states, seeing what's inside of them and, in some cases–which frankly is more about fun and curiosity–eating them. 'The whole idea is to be learning information about what the hailstone was doing when it was in the storm,' said Northern Illinois University meteorology professor Victor Gensini, one of the team's lead scientists. Calipers and crushers. It's pushing midnight on a Friday in a Texas Walmart parking lot, and at least 10 vans full of students and full-time scientists are gathering after several hours of rigorous storm chasing. Hailstones are in coolers in most of these vehicles, and now it's time to put them to the test. Researchers use calipers to measure the width in millimeters of the hailstones, which are then weighed. So far, after more than 13 storms, the biggest they found is 139 millimeters (5.5 inches), the size of a DVD. But on this night they are smaller than golf balls. Once the measurements are recorded in a laptop, the fun starts in the back of a van with a shark-festooned beach blanket protecting the floor. The hail is put on a vertical device's white holder. Jake Sorber, a meteorologist at the Insurance Institute for Business and Home Safety, squeezes a hand grip about a foot above it, and another white block comes crashing down, crushing the ice to smithereens. In the front of the van, Ian Giammanco, another IBHS meteorologist, records how much force it took to cause the destruction. 'That tells us about its strength,' Giammanco said. Different teams do this over and over, with the debris littering vans. 'It's all about trying to get good statistics on how strong the typical hailstone is.' On this night, Giammanco and colleagues are finding the day's hail is unusually soft. 'It's surprising, but there's a good theory on what's happening.' 'In hailstones we have layers. So we start off with an embryo and then you've got different growth layers,' said Central Michigan University scientist John Allen. 'That white growth is what's called dry growth. So basically it's so cold that it's like super cold liquid water freezing on surface. … All the gas gets trapped inside. So there's lots of air bubbles. They tend to make a weak stone.' But don't get used to it. Less cold air from climate change could conceivably mean harder hail in the future, but more research is needed to see if that's the case, Giammanco said. 'Damage from a hailstone is not just dependent on how fast and the exact amount of energy it has. It's 'how strong are these hailstones?'' Giammanco said. 'So a really soft one is not actually going to damage your roof very much, especially an asphalt shingle roof. But a really strong one may crack and tear that asphalt shingle pretty easily.' How to collect a pristine hailstone. Mostly researchers grab hail to test after it falls, wearing gloves so as not to warm or taint the ice balls too much. But to collect pristine hail and get it cold as soon as possible, there's SUMHO, a Super Mobile Hail Observatory. It's a chest-high metal funnel that catches hail and slides it directly down into a cooler. No contamination, no warming. Most of these pristine hailstones go directly to a cold lab in Colorado where they are sliced with a hot wire band saw. The different layers–like a tree's rings–will help scientists learn about the short but rapid growth of the ice in the storm, Gensini said. Scientists will also figure out what's in the hail besides water. Past research has found fungi, bacteria, peat moss, and microplastics, all of which helps researchers know a bit more about what's in the air that we don't see. After weeks of collecting these ice balls, Central Michigan student Sam Baron sampled the fruit of his labors. 'It tastes like an ice cube,' Baron said. 'It's like the good ice that they serve at restaurants.'
