Coastal polynyas in the southern Weddell Sea: variability of the surface energy budget

first_imgThe surface energy budget of coastal polynyas in the southern Weddell Sea has been evaluated for the period 1992–1998 using a combination of satellite observations, meteorological data, and simple physical models. The study focuses on polynyas that habitually form off the Ronne Ice Shelf. The coastal polynya areal data are derived from an advanced multichannel polynya detection algorithm applied to passive microwave brightness temperatures. The surface sensible and latent heat fluxes are calculated via a fetch-dependent model of the convective-thermal internal boundary layer. The radiative fluxes are calculated using well-established empirical formulae and an innovative cloud model. Standard meteorological variables that are required for the flux calculations are taken from automatic weather stations and from the National Centers for Environmental Production/National Center for Atmospheric Research reanalyses. The 7 year surface energy budget shows an overall oceanic warming due to the presence of coastal polynyas. For most of the period the summertime oceanic warming, due to the absorption of shortwave radiation, is approximately in balance with the wintertime oceanic cooling. However, the anomalously large summertime polynya of 1997–1998 allowed a large oceanic warming of the region. Wintertime freezing seasons are characterized by episodes of high heat fluxes interspersed with more quiescent periods and controlled by coastal polynya dynamics. The high heat fluxes are primarily due to the sensible heat flux component, with smaller complementary latent and radiative flux components. The average freezing season area-integrated energy exchange is 3.48 × 1019 J, with contributions of 63, 22, and 15% from the sensible, latent, and radiative components, respectively. The average melting season area-integrated energy exchange is −5.31 × 1019 J, almost entirely due to the radiative component. There is considerable interannual variability in the surface energy budget. The standard deviation of the energy exchange during the freezing (melting) season is 28% (95%) of the mean. During the freezing season, positive surface heat fluxes are equated with ice production rates. The average annual coastal polynya ice production is 1.11 × 1011 m3 (or 24 m per unit area), with a range from 0.71 × 1011 (in 1994) to 1.55 × 1011 m3 (in 1995). This can be compared to the estimated total ice production for the entire Weddell Sea: on average the coastal polynya ice production makes up 6.08% of the total, with a range from 3.65 (in 1994) to 9.11% (in 1995).last_img read more

International activity

first_imgThe Irish Bread Bakers Association (IBBA) warned that poor harvests in various parts of the world had dramatically increased the cost of wheat.World wheat stockpiles are at their lowest level in 25 years. Prices have surged to 10-year highs after a drought in Australia threatened to cut its harvest in half. Australian Crop Forecasters cut its estimates for 2006/7 to 11.5 million tonnes, from 25 million a year earlier. Harvests have also been hit in Ukraine and North America.Paul Kelly, director of Food and Drink Industry Ireland, speaking on behalf of IBBA, said: “The major increase in the cost of raw materials comes at a time when other business costs are also rising much faster than general inflation. Bakers are experiencing increases of up to 20% in the cost of flour and increases of over 30% in the cost of gas, their main energy source.”He said that cost increases must eventually be reflected by retail prices. “This does not mean that price increases are profit increases,” said Kelly. “While there is little that can be done about rising global prices, the government must reign in spiralling business costs. The cost of energy and waste management are just two areas where decisive action is needed.”Over the past two years, a number of bakeries in Ireland have closed or significantly rationalised their businesses.”Failure to recoup cost increases in the marketplace will lead to further rationalisation and job losses,” said Kelly.last_img read more

A God of heft

first_imgThe man dubbed President Obama’s pastor, Joshua DuBois, said Monday night he is dismayed that Americans turn to God to resolve “infinitesimally small” questions not worthy of the Almighty.“If there is one gnawing sadness I have about the contemporary state of religion in America,” DuBois said, “it is that instead of seeking God’s name for the big things, the nearly impossible things, the things that stretch faith nearly to the breaking point, that require a strong God, far too often we make God do the infinitesimally small.”God used to get called on for higher causes, but not now, DuBois said, because people are afraid he won’t show up. DuBois said people have to take a leap of faith and risk failure on their own. He delivered the annual Noble Lecture, titled “Approaching the Ledge: Why America Needs a Crisis of Faith — and Why, in Order to Save Religion, We Must Be Willing to Let It Die.”DuBois was special assistant to Obama and executive director of the White House Office of Faith-Based and Neighborhood Partnerships until early last year. He also is author of “The President’s Devotional,” a new collection of 365 inspiring daily prayers and poems that he had sent to the president. He is now a weekly religion columnist for “The Daily Beast.”DuBois said people should invoke God’s name when confronting seemingly intractable concerns, such as race relations, same-sex marriage, and raising from 32 percent the number of people with no religious affiliation.“Today, our courageous moral leaders seek God’s intervention for chicken sandwiches and contraceptive pills and whether the movie ‘Noah’ is an accurate depiction of the Arc,” said DuBois, citing conservative Christians. Liberals, too, “play it safe,” he said. At political gatherings, “The Bible has been replaced by ‘The Chomsky Reader.’” Progressive churches, which led the Civil Rights Movement, “have lost their ability to introduce a broken world to the healing grace of God.”Progressive churches “don’t think beyond a single tweet, rally, or meeting,” and since the shooting death of African-American teenager Trayvon Martin in Florida in 2012, black churches “have not coordinated a response to ‘stand your ground’” laws on firearms, he said.DuBois also didn’t spare those who filled the Memorial Church’s pews.“We’ve made God small, crying out to God for our personal comforts and pleasures,” he said. “A great majority of our religious discourse is built around pedestrian requests. ‘Oh, God, Give me a promotion, multiply my bank account.’”DuBois told three stories meant to demonstrate how people in crisis can be rewarded when they “approach the ledge” and ask for God’s help.In the Book of Kings, Ahab and Elijah duel to see whether Baal or God is more powerful. Ahab’s prophets unsuccessfully call on their gods to accept Ahab’s sacrifice, but Elijah’s call to God to have his sacrifice accepted is answered with fire from the sky.In Montgomery, Ala., in 1957, the Rev. Martin Luther King Jr. overcame threats to his family and continued his role leading the Civil Rights struggle. “He said, ‘God be real now, or don’t be real at all.’”Then, there was DuBois’ mother’s story. DuBois was raised in Cambridge by a single parent who never let poverty deprive her son of a happy childhood. Their VW Beetle had a hole in the floor she called a “reverse sun-roof.” For his birthday, they sprayed each other at the self-serve car wash.“I remember thinking, ‘I wish other moms were that cool,’ ” DuBois said.But unknown to DuBois, his mother lived in despair, dogged by bills and landlords. One night, in the bed they shared in their small apartment, she considered suicide, he said. She asked God for “one last chance.”“She walked right up to that ledge and demanded that the power of God call on her that very moment,” DuBois said. “My mother said she felt a physical presence on her shoulder so firm it startled her, so she knew we would be OK. Instead of her ending it all, it was a beginning, and she was determined to fight on.”Not everyone who asks for God’s help will get it, and that’s OK, he said. Jesus asked for God’s help on the cross, and still died, but he was resurrected.“Even if we fall for a little while, after a great and righteous leap, we will soar into the eternal,” DuBois said. “Even if we walk right up to the ledge and hit the ground, your very imprint will be a masterpiece, and you will be restored like Christ.”The Noble series was established by Nannie Yulee Noble in 1898, to discuss important themes in Christian thought. It is dedicated to the memory of her husband, William Belden Noble, a student at Harvard Divinity School who died while preparing for a ministry career. Past lecturers have included Theodore Roosevelt and Harvey Cox.Jonathan L. Walton, Plummer Professor of Christian Morals, moderated.last_img read more

5 Road Trip Boredom Cures

first_imgWe travel with a two burner stove and often pull over at rest stops to make meals. It’s worth taking the time out of the drive to fight the hanger. 2. Free books from your Public Library 5. Snacks Snacks Snacks Bonus for finding a series you really like and knowing you have hours and hours of listening time ahead of you. We really enjoyed the entire Harry Potter series. The narrator is wonderful and listening to the story is like playing movies in your head as your drive. Overdrive and Libby are two apps that allow you to listen to free books from your public library. You need to have a library card to get access to the books, but it’s simple to set up. Make sure to look up and request a few books ahead of time, each public library only has a few licenses of each audiobook and popular ones take a while to get access to.

It’s an investigative journalism podcast that dives deep into the life of an interesting man in Alabama. 3. Passengers Only Crafting projects on the road! I have learned how to cross stitch, embroidery, and macrame while headed down the road. The first two are great because they are smaller and can be stopped and started at any point. Sometimes I get ambitious and do a macrame project, but the excessive rope can get in the way. There are many craft stores that sell kits which are great to start out with, then you can start with projects of your own. Everyone knew this was coming. We rely heavily on Spotify random playlists to keep us occupied. The classic Road Trip playlists get a lot of attention as well. Thank you to Spotify for suppling endlessly hilariously titled playlists that you can shuffle through. Live Outside and Play Road Team here. We consider ourselves Road Trip experts. We have lived in a van for three years, driving back and forth across the country multiple times over these past few years. We sometimes take on ten-hour drives multiple times a week to get to a new festival location. All this time on the road has forced us to figure out how to entertain ourselves for hours at a time. There’s only so much time you can spend chatting, then starring at the driver, then making up songs about the town names we are passing. We’ve written some suggestions before if you’d like more tips on how to have an awesome summer road trip! We would love to hear your suggestions. Please help us add to this list! This is a no brainer, and the best of all the options. We’ve got our favorites that we cycle through, but there are thousands of options for all interests. Our biggest suggestion is to put down the money for a podcast playing app. The app that comes standard on most phones is frustrating. Sorry drivers, sometimes you have to keep your eyes on the road.

West Indies Under-19s prepare for India trip

first_img Share Share Share NewsSports West Indies Under-19s prepare for India trip by: – August 25, 2011 Tweetcenter_img 27 Views no discussions Sharing is caring! West Indies Under 19 Squad. Photo credit: Caribbean News NowBRIDGETOWN, Barbados — The West Indies Under-19 squad has assembled in Barbados for a one-week camp as they prepare for a tour of India next month. The players will spend a week at the Sagicor High Performance Centre at the Cave Hill Campus of the University of the West Indies.The players will be under the guidance of team’s management unit led by head coach Roddy Estwick, assistant coach Stuart Williams, team manager Courtney Walsh, as well as the staff of the Sagicor HPC. The WICB Selection Committee named a squad of 19 players for the camp following the recent WICB Regional Under-19 Tournament in Guyana.Several members of the squad were part of the tours of Dubai and Florida earlier this year, while six players earned selection for the first time. The new faces are: batsmen Emmanuel Lett, Bryan Gayle, Akeal Hosein and Chanderpaul Hemraj; along with left-arm spinner Larry Edward and fast bowler Marquino Mindley.Estwick said the camp was organised to do full assessments of the players and to continue the good work that was started by the team earlier this year when they beat Australia Under-19 in the three-day match and 50 Over series in Dubai in April, and hammered the USA Under-19s in four 50 Over matches in Fort Lauderdale last month.According to the head coach, the overall aim is to be “fully ready mentally and physically” for the upcoming trip to the sub-continent and “build blocks” towards winning the International Cricket Council’s Under-19 Cricket World Cup, slated for Australia in August, 2012.“We are looking at all the technical issues which came out of the tournament in Guyana and look to see how we can correct any faults and enhance those skills which the players have. During this camp we will have a strong bias toward playing spin bowling… a lot of emphasis will be placed on how to approach spin bowling, which will be very important for the lads as they prepare to go off to India. As we know, in India, you can expect to get pitches which will favour slow bowling,” said the former Barbados seam bowler.“This is a talented group of players and they all did well in the tournament. The majority played before in Dubai and Florida, but we have a few new players who have joined the group and it is important that everyone understands what we’re aiming to achieve and that we all work together for West Indies.Estwick added: “This camp we will be doing a lot of videoing as it is very important that the players see themselves and make improvements in their game. We know the areas we are looking to strengthen and the tour of India will give us a gauge of where we are and where we need to be to win the World Cup next year and bring it back to the people of the West Indies.”FULL SQUAD:Ronsford Beaton (Guyana): right-hand bat/right-arm fast bowlerAmir Khan (Guyana): right-hand bat/right-arm leg-spinnerChanderpaul Hemraj (Guyana): left-hand batDerone Davis (Trinidad and Tobago): left-hand bat/left-arm spinnerAkeal Hosein (Trinidad and Tobago): left-hand bat/left-arm spinnerSteven Katwaroo (Trinidad and Tobago): right-hand bat/wicket-keeperEmmanuel Lett (Trinidad and Tobago): right-hand bat/right-arm off-spinnerMarquino Mindley (Jamaica): right-hand bat/right-arm fast bowlerDonovan Nelson (Jamaica): left-hand bat/right-arm leg-spinnerJohn Campbell (Jamaica): left-hand bat/right-arm off-spinnerBryan Gayle (Jamaica): right-hand batSunil Ambris (Windward Islands): right-hand bat/wicket-keeperKavem Hodge (Windward Islands): right-hand bat/left-arm spinnerLarry Edward (Windward Islands): left-hand bat/left-arm spinnerKraigg Brathwaite (Barbados): right-hand bat/right-arm off-spinnerJerome Jones (Barbados): left-hand bat/left-arm fast bowlerAnthony Alleyne (Barbados): left-hand bat/right-arm off-spinnerJustin Greaves (Barbados): right-hand bat/right-arm fast-mediumKyle Mayers (Barbados): left-hand bat/right-arm medium-fastCaribbean News Nowlast_img read more

Holy Lightning Balls! What the Heck?

first_imgIt seems lightning is getting worse…more deadly and more common. Golfer Phil Mickelson’s hotel was hit by lightning in Illinois knocking off the chimney and starting a fire. And severe weather shut down last night’s Backstreet Boys concert in Hershey, Pennsylvania. Recently five workers in Wellington were blown off a roof by a bolt of lightning killing at least one. But did you know that lightning comes in balls too?Ball lightning may be an atmospheric electrical phenomenon, the physical nature of which is still controversial. The term refers to reports of luminous, usually spherical objects which vary from pea-sized to several meters in diameter. It is sometimes associated with thunderstorms, but unlike lightning flashes, which last only a fraction of a second, ball lightning reportedly lasts many seconds.Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but it is presently unknown whether these are actually related to any naturally occurring phenomenon. Scientific data on natural ball lightning is scarce owing to its infrequency and unpredictability. The presumption of its existence is based on reported public sightings, and has therefore produced somewhat inconsistent findings. Given inconsistencies and the lack of reliable data, the true nature of ball lightning is still unknown. Until recently, ball lightning was often regarded as a fantasy or a hoax. Reports of the phenomenon were dismissed for lack of physical evidence, and were often regarded the same way as UFO sightings.Natural ball lightning appears infrequently and unpredictably, and is therefore rarely (if ever truly) photographed. However, several purported photos and videos exist. Perhaps the most famous story of ball lightning unfolded when 18th-century physicist Georg Wilhelm Richmann installed a lightning rod in his home and was struck in the head – and killed – by a “pale blue ball of fire.”last_img read more
