Geomagnetic activity related NOx enhancements and polar surface air temperature variability in a chemistry climate model: modulation of the NAM index

first_imgThe atmospheric chemistry general circulation model ECHAM5/MESSy is used to simulate polar surface air temperature effects of geomagnetic activity variations. A transient model simulation was performed for the years 1960-2004 and is shown to develop polar surface air temperature patterns that depend on geomagnetic activity strength, similar to previous studies. In order to eliminate influencing factors such as sea surface temperatures (SST) or UV variations, two nine-year long simulations were carried out, with strong and weak geomagnetic activity, respectively, while all other boundary conditions were held to year 2000 levels. Statistically significant temperature effects that were observed in previous reanalysis and model results are also obtained from this set of simulations, suggesting that such patterns are indeed related to geomagnetic activity. In the model, strong geomagnetic activity and the associated NOx (=NO+NO2) enhancements lead to polar stratospheric ozone loss. Compared with the simulation with weak geomagnetic activity, the ozone loss causes a decrease in ozone radiative cooling and thus a temperature increase in the polar winter mesosphere. Similar to previous studies, a cooling is found below the stratopause, which other authors have attributed to a decrease in the mean meridional circulation. In the polar stratosphere this leads to a more stable vortex. A strong (weak) Northern Hemisphere vortex is known to be associated with a positive (negative) Northern Annular Mode (NAM) index; our simulations exhibit a positive NAM index for strong geomagnetic activity, and a negative NAM for weak geomagnetic activity. Such NAM anomalies have been shown to propagate to the surface, and this is also seen in the model simulations. NAM anomalies are known to lead to specific surface temperature anomalies: a positive NAM is associated with warmer than average northern Eurasia and colder than average eastern North Atlantic. This is also the case in our simulation. Our simulations suggest a link between geomagnetic activity, ozone loss, stratospheric cooling, the NAM, and surface temperature variability. Further work is required to identify the precise cause and effect of the coupling between these regions.last_img read more

Novice pentathletes dominate Tabs in Iffley face-off

first_imgThe leaderboard at the end of the day definitely reflected what had been a day of Dark Blue dominance, with Matt Courtis taking home the men’s individual title, his closest opposition coming from teammates Dom McLoughlin and Alex Robertson. In the women’s event Oxford were also victorious, with Rosa Chrystie-Lowe’s strong all round performance putting her well ahead of the other athletes. Considered in the light of last year’s narrow defeat in both the men’s and women’s events, the victory seems all the sweeter. Although there is a long way to go until the varsity meeting in April 2015, such strong performances across four of the five disciplines suggest that Oxford’s novice pentathletes could be strong contenders for selection when Oxford next encounter their Cambridge counterparts. Until then, our novice pentathletes will be working hard to stake their claims to take part. The competitive season for the Oxford University Modern Pentathlon Associa- tion started with a bang on November 8th when Oxford hosted their Light Blue rivals at Iffley Road. The Novice Varsity competition is a supposedly “low pressure” competition in which new pentathletes get the chance to compete against Cambridge without taking part in show jumping, one of the five sports which makes up modern pentathlon. But if that sounds easy, remember that they still have to fit in a 3km run and 200m swim on top of the fencing and shooting phases all in one day — this, then, was was hardly a lazy Saturday for Oxford’s pentathletes.The day started with fencing, in which Oxford put in a strong performance, taking the lead in both the men’s and women’s events thanks to Matt Courtis and Dani Chattendon. Although there was a strong response from Cambridge in the shooting phase, a dominant display from Oxford in the run put them back in control, with Oxford taking 1st-4th places in the men’s event and only one Cambridge athlete preventing the women from doing the same. Alex Rob- ertson and Rosa Chrystie-Lowe were victorious individually in this phase, both coming home well ahead of their competitors. It was a similar story in the pool, with the top placings again being secured by Dark Blue athletes, with Matt Courtis posting a particularly impressive time of two minutes and four seconds.last_img read more

Dozen’t bear writing about

first_img“Heidi Klum has given Victoria Beckham a year’s supply of cupcakes as a birthday present”. Seeing that headline in a national newspaper, you would be forgiven for thinking that maybe the scale of world events that week (Afghanistan, Burma, food crises) didn’t quite live up to their potential. Or at least not enough to edge this story off The Daily Mail’s agenda. Model Klum, it said, spent £1,000 on a year’s supply of cupcakes for Posh’s 34th birthday. “Ms Klum has arranged for a dozen of the confections to be delivered to the Beckhams’ Los Angeles home at 3pm every Friday,” droned the Mail. “She eats one a day throughout the week – the other five going to her husband and children.” We could go on, but there’s already enough misery in the world.last_img read more

Farrelly hilarious

first_imgTwo famous comedic brothers, countless students, and one night of insight and offbeat hilarity were all part of the mix on Monday (Nov. 22) at Kirkland House.In an event hosted by the popular series “Conversations with Kirkland” and Harvard’s Office for the Arts’ Learning from Performers program, filmmakers Peter and Bobby Farrelly, famous for their slapstick, off-color comedies such as “There’s Something About Mary” and “Me, Myself & Irene,” discussed their successes and failures in show business, and offered the crowd tips on what it takes to make it in Tinseltown.Natives of Cumberland, R.I., they quit their day jobs in the 1980s and headed to Hollywood, intent on breaking into the business. “We literally just read from a book about how to write a screenplay and started writing,” said Bobby.After a decade of almost-made projects and rejected scripts, they were close to giving up when they hit it big with the 1994 comedy “Dumb & Dumber,” starring Jim Carrey and Jeff Daniels. Their break came when a producer suggested they stop trying to find a director for their film and simply direct it themselves.“It hadn’t really occurred to us, because we didn’t really know what a director does,” said Bobby. “We didn’t know when to yell ‘action,’ ” added Peter, “but we understood what we wanted.”The brothers, who feared they would be exposed as frauds, decided to hire smart people around them and not profess any knowledge of the role of director. Their jury-rigged plan worked. “We figured they were going to come in and broom us and put a real director in, and they never did,” said Peter.Trusting in themselves has proven a successful formula for the brothers, who also said working in tandem has helped them to navigate the pitfalls of major movie studios that push to make a film the way they want it.“You hold each other [and your ideas] up. And it’s a huge advantage having a brother who is your partner who you also know has your best interests,” said Peter. “You are defending each other.”Asked if they bend their humor toward demographics, they said that while their jokes often tend to fall into the “teenage boy” category, they target their own sense of humor above all.“The first thing we do is to try to make sure that we think it’s funny,” said Bobby.“Yes, teenage boys come into it,” added Peter, “only because I think that’s what appeals to us.”They developed the script for their popular 1998 film “There’s Something About Mary” from an original concept borrowed from a couple of friends, and chose to break with the PG-13 rating assigned to most comedies then. “We said … let’s go nuts,” recalled Peter of their decision to push the envelope with the R-rating.But in the end the movie worked, like many of their films, they said, because the story is fundamentally uplifting.“At the heart, almost every story we do is a sweet story, and it’s a story that has a good message. It’s just [that] it’s disguised by the big gags,” said Bobby.To conclude, the Farrellys screened a clip with Kate Winslet and Hugh Jackman from a forthcoming film project titled “Movie 43.” If the reaction from the crowd was any indication, die-hard Farrelly fans will not be disappointed.last_img read more

Land value

first_imgBy Brad HaireUniversity of GeorgiaPeople touting the value of land will often say, “They’re not making any more of it.” Because “they” really aren’t making more land, a University of Georgia economist wants to place values on rural lands that he says are in a tug-of-war between rural and urban interests.”There are emerging land-use conflicts in rural areas,” said John Bergstrom, an economist with the UGA College of Agricultural and Environmental Sciences. New residents want more land for housing and amenities. Longtime residents want land for farming and forestry. For Bergstrom’s research, he divides land value into to two categories: consumptive and nonconsumptive.The consumptive value is what can be extracted from the use of the land. This includes the value of its agricultural, forestry, hunting and fishing products. The nonconsumptive value is the value of the things “that are not harvested,” he said. He considers things like residential and ecological value.The consumptive value of rural land has been well documented, he said. Reports compiled by CAES scientists break this down annually by commodity and county. For example, the annual farm-gate value (the value of farm products leaving the farm) in Habersham County, in north Georgia, is $253 million. For Colquitt County, in south Georgia, it’s $287 million. But placing a value on the nonconsumptive values of rural land is harder, he said. “The data we do have suggests that the nonconsumptive value of land is growing,” Bergstrom said.In 1996, an acre of farmland in north-central Georgia was worth $4,500, according to a CAES study. An acre there now costs $12,000.”It would be likely that this land is not going to be used for agriculture,” Bergstrom said. “It is being bought for development or being bought for speculation.”The price of farmland in south Georgia, where most of the state’s row crops are grown, has increased, but not at the level in north Georgia. An acre of farmland in south Georgia costs $1,000 per acre, about $200 more per acre than a decade ago.”But even in south Georgia there’s a trend where people are bypassing the suburbs and moving farther out into the country and into areas of traditional agriculture,” he said. “This is called exurban development.”Bergstrom’s future research will focus on better quantifying the nonconsumptive value of rural land by using geographical information systems, or GIS, and conducting surveys. He wants to create a database of information.”The reason we want to do this is to provide information for solutions to these conflicts, which I believe will only continue to grow,” Bergstrom said. “The information could be used by private landowners and local governments to set priorities for protection or the development of different land.”Bergstrom knows Georgians are interested in preserving farmland. According to a survey he conducted three years ago, Georgians would be willing to contribute through a one-time tax about $62 per household to preserve 100,000 acres or $81 to preserve as much as 2 million acres.Bergstrom just returned from a one-year leave of study in Colorado, a state which has for many years collected data on the value of rural land, he said. He will apply in Georgia some of the data-collecting techniques he learned there.last_img read more
