A downscaling approach towards high-resolution surface mass balance over Antarctica

first_imgThe Antarctic ice sheet surface mass balance shows high spatial variability over the coastal area. As state-of-the-art climate models usually require coarse resolutions to keep computational costs to a moderate level, they miss some local features that can be captured by field measurements. The downscaling approach adopted here consists of using a cascade of atmospheric models from large scale to meso-g scale. A regional climate model (Modèle Atmosphérique Régional) forced by meteorological reanalyses provides a diagnostic physically-based rain- and snowfall downscaling model with meteorological fields at the regional scale. Although the parameterizations invoked by the downscaling model are fairly simple, the knowledge of smallscale topography significantly improves the representation of spatial variability of precipitation and therefore that of the surface mass balance. Model evaluation is carried out with the help of shallow firn cores and snow height measurements provided by automatic weather stations. Although downscaling of blowing snow still needs to be implemented in the model, the net accumulation gradient across Law Dome summit is shown to be induced mostly by orographic effects on precipitation.last_img read more

Vulfpeck Debuts “Baby I Don’t Know Oh Oh” With Woody Goss On Sax

first_imgVulfpeck recently wrapped up a sold-out European tour that followed three nights at NYC’s Brooklyn Steel. The band’s success is palpable, and continued over the weekend with their first of two performances at Austin City Limits. To kick off their week in Austin, the funk quartet performed two late night performances at Emo’s. Billed Vulfpeck w/ Joey Dosik, the fivesome took the opportunity to perform their newest single “Baby I Don’t Know Oh Oh” from Vulfpeck’s upcoming seventh studio album, Mr. Finish Line.The original recording of “Baby I Don’t Know Oh Oh” is a methodically soulful ballad sung by featured guest pianist/vocalist Charles Jones, though it was sung live by featured guest Joey Dosik who frequents with the band for their live performances. Even better, keyboardist Woody Goss stood up to perform the saxophone solo–a rarity–surprising fans beyond belief. Watch the live debut of “Baby I Don’t Know Oh Oh” below, courtesy of Lefferson Jam:Watch the official music video for “Baby I Don’t Know Oh Oh” below:The excellent new track marks the second to be released by the band since the announcement of Mr. Finish Line, following the cover of Mocky‘s “Birds of a Feather, We Rock Together” sung by Antwaun Stanley that they released a few weeks back. The band hasn’t indicated whether the singles will be included on the upcoming album. In the past, they have released several covers and singles that have not made it onto official LPs.Vulfpeck Shares First Track, New Music Video Featuring Antwaun StanleyAccording to the video the band released along with the album’s announcement, Mr. Finish Line will feature “10 Indi Bangers from the band that recorded Newsbeat,” a nod to their 2014 Fugue State tune. The album will feature a long list of contributors, including Stanley, Jones, Christine Hucal, legendary session guitarist David T. Walker, Danish vocalist Coco O., legendary session drummer James Gadson, funk bassist/singer/songwriter and member of Parliament Funkadelic Bootsy Collins, drummer for Prince during The New Power Generation era Michael Bland, keyboardist/saxophonist Joey Dosik (who bandleader Jack Stratton recently revealed will be taking lead vocals for his first Vulf tune) and guitarist/honorary 5th member Cory Wong. These talented players will, as always augment the core Vulfpeck quartet (comprised of Stratton, Joe Dart, Woody Goss, and Theo Katzman).Vulfpeck has one more performance this Friday at Austin City Limits before concluding their scheduled shows for 2018.last_img read more
