Credit: NOAAScientists at NASA’s Jet Propulsion Laboratory have applied machine learning to predict when hurricanes will suddenly intensify, with potentially damaging and deadly results, with better accuracy than ever before, according to the institution.For decades, meteorologists have tried to determine how to predict when hurricanes will suddenly strengthen.Hurricane Patricia of 2015 in the Northeast Pacific Ocean, as an example, transformed from a Category 1 storm with wind speeds of 86 mph to a Category 5 hurricane swirling at 207 mph in less than 24 hours, JPL said in a written statement.“Patricia wasn’t the first or the last hurricane to suddenly strengthen in such a short time, but it was a spectacular demonstration of a phenomenon that has plagued meteorological forecasts for decades,” the statement said. “Accurately predicting whether a hurricane will undergo rapid intensification — where wind speeds increase by 35 mph or more within 24 hours — is incredibly difficult.”JPL researchers may have reached a breakthrough with their latest project, which applies machine learning to an experimental computer model that’s shown the ability to vastly improve accurate prediction of so-called “rapid-intensification events.”Successfully forecasting a hurricane’s growth can provide people in its path extra warning to evacuate or prepare, JPL Atmospheric Scientist Hui Su explained. She co-authored a paper on the subject that appeared in the journal Geophysical Research Letters on Aug. 25.“It’s an important forecast to get right because of the potential for harm to people and property,” she said.The computer model makes use of a plethora of data points, including rainfall rate, ice water content, temperatures and more.“There are so many variables inside a hurricane, and they interact in such complex ways that many current computer models have trouble accurately depicting the inner workings of these storms,” according to the JPL statement. “Machine learning, however, is better able to analyze these complex internal dynamics and identify which properties could drive a sudden jump in hurricane intensity.”The team made use of the computing power of IBM’s Watson Studio to create the model.After comparing their model with years worth of data from past hurricanes, “For hurricanes whose winds increased by at least 35 mph within 24 hours, the researchers’ model had a 60 percent higher probability of detecting the rapid-intensification event compared to the current operational forecast model,” the JPL statement said. “But for those hurricanes with winds that jumped by at least 40 mph within 24 hours, the new model outperformed the operational one at detecting these events by 200 percent.”The researchers, along with partners at the National Hurricane Center, are already testing the model on new storms to gauge how well it predicts hurricane growth.“In the future, they plan to sift through satellite data to find additional hurricane characteristics that could improve their machine learning model,” the statement said.

Saint Mary’s hosts parents

first_imgPhoto courtesy of Saint Mary’s Parents from around the country gathered at to Saint Mary’s College this weekend to visit their daughters and learn more about their academic lives during the annual Sophomore Parents’ Weekend (SPW).Sophomore class vice president Maggie Carswell said the class boards organized SPW in the past, but this year Student Affairs and Student Involvement and Multi-cultural services (SIMS) coordinated the weekend events.“It was mostly [vice president for student affairs] Karen Johnson and Student Affairs,” she said. “They helped a lot deciding to get all the faculty together to come up with all the info sessions and helped decide what would be most helpful for the parents.“They told us the game plan, and we agreed because we thought everything was important. It was more helpful because they gave us a different perspective. As students it is hard to know what your parents want to see.”Although SPW is usually held in February, Carswell said the event was moved to the fall semester to allow parents the opportunity to gain a better perspective on the process of choosing and declaring majors.“Normally our sophomore parents weekend is in the early spring, but we changed it to the fall because after I met with faculty and Academic Affairs ,we felt the information that sophomore parents needed, they needed in the fall to help their daughters prepare for the spring,” Johnson said. “Also the sophomore class is a forgotten class. Freshmen you spend a lot of time with, juniors and seniors are getting ready to graduate so we wanted to give [sophomores] a little bit more attention and help and assistance.”Friday events involved a check-in process followed by a small reception later in the evening, Johnson said. According to the Saint Mary’s SPW schedule, Saturday events included information sessions on navigating majors, succeeding during sophomore year and understanding post-graduate options. Sunday morning activities included zumba, Mass and a tour of the Heritage Room.“They’ve been in academic sessions all day and had a lunch-in, and there’s receptions [Saturday] afternoon,” she said. “A lot of our faculty is coming in for the reception so parents can meet them. Then there will be a photo booth later and a game watch party.”Sophomore class president Ellen Raymond said she was thankful to Johnson, the faculty and the SIMS office for their involvement in coordinating the weekend.“We want to thank Karen Johnson and the SIMS office,” she said. “We want to thank the faculty for coming out on a Saturday too to come talk to us. It really provided a wholesome experience to see faculty with them.”Tags: Sophomore Parents Weekend, SPW, Student Affairslast_img read more

Suriname bodybuilders dominate local counterparts at Stage of Champions IV

first_img-Visitors win overall Mr. Physique and Ms. Bikini titlesSURINAME dominated Saturday night’s Camille’s Academy Stage of Champions IV by winning all the major titles up for grabs, including the coveted overall trophy and $200,000, which was won by Mr. Suriname 2019, Fabian Wehl.Ms. Bikini winner Malitia Galimo (left) and second place finisher, Rosanna FungThe international battle lived up to expectation with a large influx of Surinamese and competitors from Trinidad and Tobago and Antigua and Barbuda travelling to challenge their local counterparts at the Theatre Guild in Kingston, Georgetown.The event was not without its moments and although it might not have been the results that the locals were anticipating, there were some nostalgic periods, especially with Sylvan Gardner turning back the years to make his way into the championship round, but the 37-year-old Wehl was in immaculate condition and his imposing frame made him a clear favourite.The Surinamese biggest challenge was actually in the heavyweight division, which had some well-sculpted specimens. Our local boys Carlos Petterson (eighth position) and Julio Sinclair (seventh) finished at the bottom in that division.The final four of the heavyweight class were all Surinamese and the striking Sergio Holwyn, a crowd favourite, finished a close second. Jermin Karg placed third, while Jermain Weisen settled for fourth.Multiple-time winner of the Senior National title in the Twin Island Republic, Michael Callender, finished fifth, whilst Antigua and Barbuda’s representative, Warren English, placed sixth.English, a Guyanese by birth, opted for a smaller look than when he guest-posed at the Senior National Championships in August, which seemingly worked against him.TURNING BACK TIMEThe favourite battle for the local audience took place earlier when Gardner was able to upstage Mr. Guyana 2019, Marlon Bennett, in the Under 154 pounds division—in a five-member all-Guyanese showdown.The four-time CAC gold medal winner, Gardner, who was a late addition to team Guyana, looked very proportional.Fabian Wehl is Mr. Stage of Champions 2019.Darious Ramsammy, who just returned from the CAC, placed third while Andre Wagner copped fourth and Donald Lindie fifth.Rising star, Derran Harris also featured in the overall championship clash. The 26-year-old was the only other Guyanese to win a division title.In a repeat of the Senior National Championships, he again upstaged Tejpaul Gwendsammy in the Under-143 pounds battle. Ghamsham Goberdan placed third.Neither Gardner nor Harris finished in the top three in the overall battle. The latter bowed out at fifth position, while Guyana’s most accomplished CAC champion, Gardner, finished fourth.Wehl, who later claimed that the championship trophy was one of the best in his career, finished ahead of compatriot, Randal Haakmat, who had won the U164 division.T&T’s 2018 National Junior Champion, Barry Copilah placed third. Copilah had edged past Guyanese Lindon ‘Muscles’ Burnett, who impressed the audience in the U176 division.Mr. PHYSIQUEWithout the services of two of our best Mr. Physique campaigners, Emmerson Campbell and Yannick Grimes, who just represented Guyana at the CAC Bodybuilding Championships, and without second place finisher at this year’s National Championships, Tariq Dakhil, leadership was left on the shoulders of Delroy Phillips, who is the reigning Mr. Physique novice.Although Phillips was tapered and looked solid, Rudolph Getrouwcosta and fellow Surinamese Fernando Krak (second place) beat him into third place.Two other Guyanese battled in the eight-person competition: Renaldo Caldeira placed fifth, while Johnathan Jeffery finished sixth.Meanwhile, in the Ms. Bikini battle, a tanned 2019 Senior Champions winner, Rosanna Fung, settled for second place behind Surinamese Malitia Galimo.The other Guyanese in the five-woman competition, Amrita Sewdas, settled for fifth. Sewdas lacked confidence on stage, which was to her detriment.last_img read more
