Trends in Antarctic geopotential height and temperature: A comparison between radiosonde and NCEP-NCAR reanalysis data

first_imgA comparison of 40-yr (1960-99) trends in Antarctic geopotential height and temperature from quality controlled radiosonde observations and NCEP-NCAR reanalysis (NNR) data is undertaken. Observations from four Antarctic stations-having sufficiently long-term and consistent datasets-at four pressure levels (850, 500, 300, and 100 hPa) are utilized. The NNR reveals substantial negative trends in tropospheric geopotential height at high southern latitudes with no significant trends seen in the lower stratosphere above Antarctica. In contrast, observations indicate only minor negative trends in tropospheric height, while statistically significant decreases in height in the lower stratosphere have occurred over East Antarctica. However, both NNR and observations show a consistent, significant warming (similar to1degreesC) in the lower troposphere (>500 hPa) above coastal Antarctica. At higher altitudes, trends derived from the two datasets diverge; the NNR fails to capture the marked cooling in the lower stratosphere associated with seasonal ozone loss. Differences in the trends are principally caused by NNR errors prior to the assimilation of satellite sounder data, which coincides with significant jumps in NNR upper-air temperatures. A rapid drop in NNR tropospheric geopotential height across East Antarctica as recently as 1993 is traced to the introduction of automatic weather stations in the region. Errors in the model height of these surface pressure data cause a significant climate jump in the NNR not observed in comparable models. Such spurious jumps considerably diminish the usefulness of the NNR for climate change studies in Antarctica.last_img read more

Singapore economy seen to contract 4-7% as pandemic impact worsens

first_imgThe circuit breaker measures will start being lifted in phases on June 2.The ministry cautioned that “there continues to be a significant degree of uncertainty over the length and severity of the COVID-19 outbreak, as well as the trajectory of the economic recovery, in both the global and Singapore economies.”Irvin Seah, senior economist at Singapore’s largest bank DBS, said the downward revision was not surprising as the previous growth projection was no longer tenable after Singapore extended its semi-lockdown beyond May 4.He added that the full impact of the pandemic will be felt only in the April-June period, saying that the “significantly weaker global demand, labor shortage in the construction sector, supply chain disruptions and restrictive measures imposed during the circuit breaker will inflict a severe blow to the economy.”Topics : This marked the third time the ministry has cut its economic projection for Singapore for 2020 since the virus outbreak earlier this year. The previous revision came in March.The Singapore economy last went into negative growth in 2001, when annual GDP fell by 1.1 percent.The ministry said in a statement that the latest downgrade was due to “the deterioration in the external demand outlook for Singapore as well as the expected economic impact” from a semi-lockdown implemented by Singapore to curb the spread of COVID-19, the respiratory illness caused by the virus.The semi-lockdown, which led to the shutdown of most workplace premises in Singapore, has “dampened domestic economic activity, along with domestic consumption,” it said. Singapore further downgraded its 2020 growth forecast on Tuesday, projecting a 4 to 7 percent contraction as the impact of the coronavirus pandemic has worsened.The Ministry of Trade and Industry previously forecast the highly trade-dependent city state’s gross domestic product would shrink by 1 to 4 percent in 2020.The revision coincided with the release of data showing the economy had contracted in the first three months of this year by 0.7 percent year on year, and by an annualized 4.7 percent from the previous quarter.last_img read more

Ibrahimovic Wins Community Shield for Man Utd

first_imgJose Mourinho began his reign as Manchester United manager yesterday with a trophy as Zlatan Ibrahimovic scored a late header to beat Leicester in the FA Community Shield at Wembley.Jesse Lingard, who scored the final goal of the Louis van Gaal era with the winner in the FA Cup final against Crystal Palace, put United ahead before half-time when he ran 40 yards and beat four men to slot home.League champions Leicester replied when Marouane Fellaini’s dreadful back-pass let Jamie Vardy in to round David de Gea and score.But summer signing Ibrahimovic, 34, typically had the final word with seven minutes to go, rising to meet Antonio Valencia’s cross and beat Kasper Schmeichel via the post.The outspoken Swede had stated beforehand that the shield would be the first trophy he would be bringing home as a United player, and so it proved for the veteran striker.Leicester had brought Mourinho’s second stint in charge of Chelsea to an end with a 2-1 defeat at King Power Stadium in December on their way to the title but this was a much happier occasion for the Portuguese.Mourinho has even more reason to be cheerful ahead of the start of the new Premier League season next week as United announced before the game that Paul Pogba is set to have a medical before a potential return to Old Trafford for what would be a world-record fee.Rather than start with any of his six summer signings, Leicester boss Claudio Ranieri brought in long-serving Andy King to replace N’golo Kante who left for Chelsea in the heart of his midfield, and his side continued to sit back, absorb the opposition’s possession and threaten on the break through Vardy’s pace.Like last season, they also threatened from set-pieces, with Shinji Okazaki heading against the bar from an early corner.It was only at the break, with his side trailing, that Ranieri tried something different, bringing on summer signing Ahmed Musa and Demarai Gray.Nigeria international Musa, who cost a club-record £16m from CSKA Moscow, had already made a splash in pre-season with his performance against Barcelona and he made an instant impact with his part in Leicester’s equaliser.It was Fellaini who played the final ball but Musa had burst forward to put United on the back foot in the first place, and he almost grabbed a late leveller from Robert Huth’s header as well.Share this:FacebookRedditTwitterPrintPinterestEmailWhatsAppSkypeLinkedInTumblrPocketTelegramlast_img read more

Black Stars’ Golden Legends of 78 to be honoured

first_imgSome members of the Black Stars who conquered Africa in Accra and Kumasi to win the Nations Cup in 1978 are set to be awarded at the second edition of the National Player Awards in June.The awards which is a collaborative project between Proton Sports Services and the Retired National Footballers Association of Ghana (RENFAG) is aimed at bestowing honours on gallant men and women who had dedicated their lives and energy towards serving the nation in football.Last year’s edition saw the Black Stars’ squads of 1963, 65, 78 and 82 being honoured as Black Stars’ captain Asamoah Gyan swooped a double, including the most dedicated player of the team.Spokesperson for the National Player Awards, C.K. Akunnor told JOY Sports all is set for a more improved showpiece in June.“We are very young in terms of organizing events such as this, so definitely there would be lapses. But we have learnt from our mistakes and we are certain we will deliver a better awards ceremony this time round.”Asked what the novelty for this year’s ceremony would be, CK Akunnor said “this year we have decided to award some of the members of the Black Stars Africa Cup of Nations winning squad of 1978. We call them the Golden Legends. We believe they served the country well, just as all national sports men and women have so we would like to honour them for their dedication and selflessness.” The second National Player Awards will officially be launched on Tuesday May 14 2013 at the Media Center of the Accra Sports Stadium with the main event scheduled to take place in June.last_img read more

Fletcher: Why I don’t care about cheating in Hall of Fame voting

first_imgBarry Bonds, Roger Clemens and Manny Ramirez all cheated.And I don’t care.I know I’m supposed to care, but if I’m being totally honest with myself, and not just feeling what I’m supposed to feel, I just don’t.These guys are just baseball players, and I’m really not looking for them to be anything more. Sure, the ballot says I should take “character” into account, but the Hall is already dotted with people of questionable character, so the bar is pretty low.I have voted for the “steroid guys” in part because it didn’t bother me that much, but also because I didn’t feel it bothered the sport that much.Major League Baseball allowed, and I believe even encouraged, players to use performance-enhancing drugs during that era. I wasn’t going to punish them retroactively.Ramirez, though, was a part of a slightly different era, when MLB tested for steroids. He was suspended twice, so he presented a new question. Logically, I could justify distinguishing him from Bonds and Clemens.As I thought about it, though, Ramirez’s PED use still didn’t bother me. It just didn’t. The outrage just isn’t there.These are just baseball players doing what high-level athletes do, which is push the envelope to wring every ounce of performance out of their bodies.They live in a world where a tiny decline in physical skill can cause a huge decline in results. A little less fastball, a little less bat speed can mean the end of a career.The players in the 1960’s and 70’s who popped amphetamines were doing the same thing, even though it didn’t work as well.The difference was science, not integrity.Legendary Negro Leaguer Buck O’Neil famously said: “The only reason players in my time didn’t use steroids is because we didn’t have them.”So let’s just dispense with the “character” charade. The Hall of Fame is a museum that recognizes the best baseball players.Period.Now that we’ve lifted the PED question from the Hall of Fame ballot, it becomes only slightly less complicated, though.It’s still a hair-splitting exercise of distinguishing the top 1 percent from the top 2 percent.It’s easy to check the names of Bonds, Clemens and Ramirez, and not that difficult to add Jeff Bagwell, a PED-suspected player whose numbers easily place him among the best first basemen of all time.I also checked the box for Tim Raines, who I have voted for consistently for years.Those five boxes checked, there were 13 others I felt deserved a long look.They included five I had previously deemed worthy of a yes: Jeff Kent, Gary Sheffield, Trevor Hoffman, Curt Schilling and Mike Mussina. There were five on whom I’d passed previously: Edgar Martinez, Fred McGriff, Sammy Sosa, Larry Walker and Billy Wagner. And there were three new names: Vladimir Guerrero, Pudge Rodriguez and Jorge Posada.I took a fresh look at all 13. I was searching for dominance and longevity, but mostly the former.Give me Sandy Koufax over Don Sutton every time.I prefer high-rate stats to raw accumulations of hits or homers.Without getting too deep into the numbers, I quickly realized I’d been underrating Martinez. He had nine seasons with an adjusted OPS+ of 150, the most of any hitter on my list.I had been discounting his stats too much because of being a DH or not having a long enough career. He did enough. I voted for Martinez, for the first time.The same type of analysis also encouraged me to drop Kent and Sheffield, who didn’t have as many dominant seasons as I’d remembered when I voted for them before. Sosa, Posada and McGriff also came up a little short by the same logic.Rodriguez and Guerrero also had fewer dominant seasons than I’d expected, but still earned my vote.With Rodriguez, his defense put him over the top. He won 13 Gold Gloves, and was probably the best defensive catcher in history.As for Guerrero, this combination is hard to ignore: He hit .318 with 449 homers. The only five other players who can match both of those are Babe Ruth, Jimmie Foxx, Ted Williams, Lou Gehrig and Stan Musial. Those aren’t merely Hall of Famers, they are short-list, best-of-the-best, inner-circle Hall of Famers.That leaves Walker, whose numbers definitely warrant induction, especially in terms of dominant seasons. I certainly might vote for him in the future, but for now he doesn’t make my cut because of the Coors Field factor. His career OPS on the road was .865, which is very good but not quite Hall of Fame-worthy.Now, the pitchers. Schilling and Mussina were relatively easy. Both of them rank above the average Hall of Famer in adjusted ERA. Schilling also had a 2.23 postseason ERA, leading his teams to three World Series titles.And that’s 10, the limit.Hoffman had gotten my vote before, but when I looked deeper, his ERA and WHIP weren’t all that special among the other closers of his era. And he wasn’t even as effective as Wagner. Hoffman’s ERA+ was 141, compared to Wagner’s 187.Wagner, however, came up a little short in quantity. He pitched almost 200 fewer innings than Hoffman, and Hoffman had him by 183 saves.If you could combine Hoffman’s quantity with Wagner’s quality, you’d have a Hall of Famer.Call him … Mariano Rivera. He’ll get my vote when it’s his time.Hoffman and Wagner? Not now. Especially not since I would have had to knock off someone else to vote for either. I couldn’t justify either of them over any of the other 10.But I will look at them all again next year.center_img Newsroom GuidelinesNews TipsContact UsReport an Errorlast_img read more
