The dynamics of idealized katabatic flow over a moderate slope and ice shelf

first_imgA non-hydrostatic numerical weather prediction model has been employed to Simulate idealized katabatic flows over a moderate slope and adjoining ice shelf. The topography of Coats Land and the adjoining Brunt Ice Shelf. Antarctica. has been used: this is typical of much of the Antarctic coastline. The Regional Atmospheric Modeling System Version 4.3 has been adapted for simulations over compacted snow, most notably through changes to the multi-layer soil model. The Simulations are initialized using clear-sky conditions and at rest. On the slope. a shallow katabatic flow develops, the winds becoming approximately steady on the slope by similar to12 h. The peak downslope winds are about 7 m s(-1) at 30 m above the snow surface. The katabatic flow depth ranges from 50 to 100 m down the slope. Over the ice shelf the katabatic flow peters out, while a pool of cold air develops, primarily through sensible-heat loss into the surface and partially balancing the net radiative-heat loss to space. Near-surface and Sounding data from the model simulations compare well with archetypal and typical katabatic flow observations. especially after some tuning of the model’s turbulence parametrization. An analysis of the downslope flow dynamics shows the buoyancy force is generally balanced by the inertial force. except towards the foot of the slope where it is balanced by upslope forces related to gradients in the potential-temperature deficit and katabatic-layer height. caused by the pool of cold air over the ice shelf. Over time, the cooling of the ice shelf boundary layer leads to an apparent retreat of the katabatic flow from the ice shelf and some way up the slope. The dynamical analysis explains the surface climatology observed, such that the persistent katabatic winds of Coats Land rarely reach the Brunt Ice Shelf. The simulated katabatic flow moves from ‘shooting’ to ‘tranquil’ towards the foot of the slope. This transition acts to trigger a train of internal gravity waves which propagate energy upwards away from the katabatic flow JUMP. Previous studies have also found shooting to tranquil katabatic flow transitions, so to generalize these findings Would suggest that internal gravity-wave generation is ubiquitous around much of coastal Antarctica and Greenland.last_img read more

O’Connell talks television

first_imgContent will continue to be the most important aspect in the future of the rapidly changing television industry, Katie O’Connell told students in a lecture Monday night. O’Connell, senior vice president of drama development for NBC, graduated from Notre Dame in 1991 and has experience as an executive producer for NBC and CBS. She has also worked on major television shows such as 30 Rock, 24 and Law and Order. “Content will always be king,” she said. “Television is changing so rapidly, so the biggest piece of advice I can give you is to be on top of it.” Many of the students who attended O’Connell’s lecture were Film, Television and Theatre majors. She said they were lucky because that major did not exist when she was a student at Notre Dame. She graduated with a degree in American Studies. O’Connell began her lecture by describing the many different types of jobs that are available in the television industry today, including careers with networks, as managers and agents or as members of television shows’ creative teams. She discussed the most well-known jobs in the industry, but also encouraged students to explore lesser-known jobs. Students should save their money if they plan to move to Los Angeles, O’Connell said, as it is difficult to find a steady income in the field of television. O’Connell concluded the lecture with her thoughts on the future of television. She said the television business was moving toward becoming entirely digital, and mentioned the newly available online rentals of Apple and Amazon. “Work with the architects of change,” she said. O’Connell said although the transition into a more digital version of television may not occur in the next five years, but it will happen in the lifetime of today’s college students.last_img read more

ATP to oppose pay rises for top management at Danish companies

first_imgDenmark’s DKK759bn (€102bn) statutory pension fund ATP is using its clout as a shareholder to keep a lid on rising pay for top executives at Danish companies, saying the right level of remuneration for corporate leaders increases shareholder value.Claus Berner Møller, vice president for Danish equity at the Hillerød-based pension fund, said: “In general, we are experiencing upward pressure because the level of pay is so much higher in, for example, the US and Switzerland.“We are trying to fight against this pressure because we think that generally, the level in Denmark is appropriate.“We are spending quite a bit of time discussing remuneration, because we believe that the right salary package for executive directors and supervisory boards increases shareholder value.” The supplementary labour-market pension fund was also concerned about overly generous recruitment or severance deals for managers, Berner Møller said.“Fundamentally, we don’t think that a severance package should equate to more than two years’ salary. Similarly, we are sceptical about excessively generous stay-on and sign-on bonuses, and this type of thing,” he said.Berner Møller made the comments in an interview with Danish broadsheet Morgenavisen Jyllands-Posten, which were confirmed by a spokesman for the pension fund.Pension funds in the UK have also been vocal on the matter of executive pay in recent months, with industry association the PLSA saying in January that “provocative levels” of executive pay were damaging the reputation of British business.last_img read more

UK regulator urges long-term focus in trustee guidance

first_imgThe UK’s Pensions Regulator (TPR) has urged DB pension fund trustees to take a long-term view of investment risks, governance, and strategy in fresh guidance published this week.The lengthy online document detailed the regulator’s expectations of trustees in charge of defined benefit (DB) pensions, and came as part of a wider push to improve scheme governance.Fred Berry, TPR’s head of investment consultancy, said: “The investment strategy is one of the most important drivers of a scheme’s ability to meet the objective of paying the promised benefits as they fall due, and we expect trustees to set this in the context of their integrated risk management approach.“It’s important to set clear investment objectives for your scheme and to identify how and when they should be achieved. Our guidance states that trustees should focus on areas that have the most impact for meeting their scheme’s objectives, and identify the necessary skills for the board of trustees of their scheme. It also provides some practical guidance on how to get the best from their advisers.” The guidance encouraged trustees to focus on “highest level strategic decisions” and delegating other tasks to third parties, including consultants and fiduciary managers.It also emphasised the importance of establishing policies for stewardship of assets – particularly when this responsibility is delegated to a third-party asset manager – and for long-term risks such as climate change.“Most investments in pension schemes are exposed to long-term financial risks, which may include risks around long-term sustainability,” the regulator stated. “These can relate to factors such as climate change, responsible business practices and corporate governance. We expect you to assess the financial materiality of these factors and to allow for them accordingly in the development and implementation of your investment strategy.”Stuart O’Brien, partner at Sackers, said: “TPR is right to draw out specific elements such as ESG, as trustees need to take an active decision as to whether these factors are financially material for their scheme – something which is not always straightforward in practice.”The regulator also emphasised the importance of cash flow matching and modelling.Calum Cooper, head of trustee consulting at Hymans Robertson, welcomed this, but warned that most cash flow modelling systems “typically don’t allow for the primary reason schemes hold assets: i.e. for income to pay the pensions promised”.He claimed this could put members’ benefits in danger, as trustees would not have a full grasp of the risks of not meeting obligations.Cooper added: “Model misbehaviour matters. Cash flows matter. The models used by schemes should reflect both asset and liability cash flows to improve the chances of paying members’ pensions in full.”TPR’s guidance is available here.last_img read more

Jack(i) of all trades

first_imgStepping up after the injuries to AnnMarie Brown and Taylor Wurtz, Jacki Gulczynski has became a scoring and rebounding machine in her sophomore season.[/media-credit]It’s often said life can work in mysterious ways, and everything – whether good or bad – happens for a reason. Even the most disappointing, heartbreaking moments can have a lining of silver behind them that is not at first visible.When the Wisconsin women’s basketball team (11-13, 3-8 Big Ten) lost both Taylor Wurtz and AnnMarie Brown to season-ending injuries earlier in the season, any possible silver lining appeared to be hidden behind the cloud of darkness as a result of the injuries. But the brief stint of darkness was shattered when sophomore forward Jacki Gulczynski burst onto the scene for the Badgers.Two games after Wurtz sat out for the first time, Gulczynski scored in double-figures for the first time in her two-year career, notching 14 against Marquette. Since that game, Gulczynski has gone on a rampage, scoring double-digits in 17 straight games including the victory over Marquette. She is also the second-leading scorer on the Badgers averaging 12.4 points per game, a mark good for 14th in the Big Ten.When asked whether she thought she would be in this scoring role at the beginning of the season, Gulczynski was quite humble and team-oriented in her reply.“Anything can happen,” Gulczynski said. “If I were to say at the beginning of the year that [being the second leader scorer] was my main goal, it wasn’t. I just seemed to come into this role and kind of do whatever my team really needed from me.”Gulczynski has not only stepped up this season with a short roster, but she has surprised many, especially with performances like she recorded last Thursday at Ohio State. Despite a 65-59 double-overtime loss to the Buckeyes, Gulczynski tallied a career-high in both points and rebounds with 32 and 15 respectively, her sixth double-double of the season.Even head coach Bobbie Kelsey was somewhat taken aback by such a dominating performance, but now says she expects more from Gulcznski with only nine active players.“I knew she was capable, but you never know until kids are in those situations whether they’re going to step up or not. It’s nice to see her step up because now we can hold her to that standard. We depend on her to do it because she has to,” Kelsey said.A year ago, Kelsey would have had trouble believing in and depending on Gulczynski, but what a difference a year makes. Gulczynski is the most improved scorer in the Big Ten this season, averaging 9.9 points better per game than she did last season. The 6-foot-1 forward is also third in the conference in three-point field goal percentage – it’s not just Wisconsin men’s basketball that has long-range post players. And with the level of consistency Gulczynski is showing, Kelsey has reason to depend on her young forward.But what has made the difference in Gulczynski’s breakout season? Well, according to assistant coach Alysiah Bond, whom Gulczynski works closely with, it’s confidence and the right attitude.“She’s more experienced, and she basically made her mind up that, ‘This is my opportunity.’ Her confidence has grown from game to game,” Bond said. “She got off to a bit of a slow start production wise, but I think she just needed to be reminded of what she is capable of. Not just talking about it, but she’s going out and showing it and done so with consistency.”That right attitude includes Gulczynski’s work ethic, which has allowed her to refine her shooting motion through many extra hours in the gym. Whether by herself, or with Bond rebounding for her, Gulczynski has proven to herself, coaches and teammates she is willing to do the work to become a better player and shooter. Nowhere has that been more evident than in the points column of the 17 most recent box scores for Gulczynski.Bond had a recent talk with Gulczynski about her expectations for this season and the upcoming ones, but said she had no worries about Gulczynski’s potential because of her drive to be better.“I never try to put a ceiling on what someone is capable of. If they put it all together, you can see glimpses. What never leaves her is her ability to knock down shots. She’s a post player, yet her stroke is sweet. Her stroke is mean. If you come in the gym and watch her she can consistently knock down shots, and she can do so outside the three, obviously,” Bond said.“When you just look at the numbers from left to right on the season, you see consistency. You see high numbers. Anytime someone can be near 50 percent from the field, 40 percent from three and 90 percent from the line you know you’re really onto something. So she has that ability. You can see with all the different ways she can score that it opens up the doors for that to happen.”So whether Wisconsin finishes first or last this season, when the final whistle blows, the Badgers will have solace in knowing their future is bright. Bright from the spark Gulczynski has lit under the Badgers this season, lining their once gloomy skies with silver. Perhaps gold is not too far in the future.last_img read more

Op Ed: “Canada is Not a Halfway House for Royals”

first_imgPrince Harry made his first public appearance since he and Meghan Markle announced their plans to step back from senior royal duties.The Queen has given her blessing for the couple to live in Canada part-time during the transition.Canada’s biggest newspaper, The Globe and Mail, out with a scathing editorial, reading in part, “Canada is not a halfway house for anyone looking to get out of Britain while remaining a royal.” The article goes on to say: “If they were ordinary private citizens, plain old Harry and Meghan from Sussex, they would be welcome. But this country’s unique monarchy, and its delicate yet essential place in our constitutional system, means that a royal resident – the Prince is sixth in the line of succession – is not something that Canada can allow. It breaks an unspoken constitutional taboo.”The Royal Family issued a statement on Monday that said there would be a period of transition as the Prince steps back. His wife Meghan Markle is already in Canada with their son, Archie. The Prince also issued two video statements today on mental health and the Invictus Games.The editorial arguing it isn’t appropriate for the country to house senior royals as a member of the Commonwealth, the family of nations where the Queen is head of state. But that might be exactly the reason why it makes sense: in 2018 she made Harry Youth Ambassador for the Commonwealth.By the way Meghan and Harry picked a great place to put down roots because a new global survey says Canada is the world’s best country in which to live behind Switzerland. Canada has moved up to number two in this year’s survey, and Japan has slipped down to number three.last_img read more
