In the Lap of the Atlantic

In the Lap of the Atlantic Anna Lena Phillips Bell Anna Lena Phillips Bell, letter from the editor, Atlantic Ocean, Michelle Donahue ________ Hello from the ocean. Which is to say, hello from a salutary winter beach walk. It's gotten pretty cold here on this coast, but a walk by the shore is often still the ticket. The view and the air never get old—this must be in part because they are already ancient—and this makes them good company. Which is also to say, hello from a set of ecosystems in dire need of support. This year the world's oceans reached the highest temperatures noted since 1958, when record keeping of this kind began, according to a paper in Advances in Atmospheric Sciences. It will take systemic change along with individual action to help our oceans go on as healthy, sustaining, sustained living systems. What action can I take? You? It's a question worth asking and asking again. Which is to say—as our team noted last spring—a magazine that sits nearly in the lap of the Atlantic ought to have an Ocean Issue. And what a delight it's been to read and consider work for it—ranging from the speculative to the research intensive and all around between. In Kim Samek's story "Garbage Patch," against the background of a near-future Seattle whose music scene has been decimated by rising rents, the intrepid Thuy seeks for a way to eat all the plastic she can wish for. In "Sexy Thing," by Amber Wheeler Bacon, a family prepares for an approaching hurricane, and the narrator's sister gets ready to go on a portentous date. The story is related by a boisterous, opinionated, touchingly frank narrator, one with whom I'd like to check in again in a few years to see how she's doing. Patricia Ononiwu Kaishian's "The Magnetism of Eels" traces the journey made by the American eel, Anguila rostrata, from ocean to river and back, and considers language, home, queer advocacy, and finding a sense of place along the way. In "The Last Good Day," Hea-Ream Lee ventures out to find and document a rare plant that grows where an even more ancient ocean once was. In Rajiv Mohabir's longer poem "Humpback Vocalizations," whale song and research on it travel across the page in a watery, magical progression. And save some of an idle afternoon for Molia Dumbleton's story from an East Coast lobster-fishing town, "Before All This." It's got poetic compression along with the expansive feel of a novel, and some of the sentences may break your heart a little. There's much more, including many oceanic poems—from new and [End Page 5] past contributors including Cherene Sherrard, Yuko Taniguchi, and Gretchen Steele Pratt—that would, I suspect, sound even finer if read near a body of water, whether it's an ocean or a bathtub. We hope you enjoy them as much as we have. ________ I'm pleased to share some good news along with this issue. This fall, we welcomed Michelle Donahue—writer, editor, teacher, and novice surfer—to our team as associate editor. She joins us having worked on some magazines I love—Quarterly West, Flyway—and brings a keen and wide-ranging editorial sensibility, not to mention a genuine sense of fun. I'm so glad to have her on board. If you'd like to hear a little about her work and editorial philosophy, check out fiction editor Becca Hannigan's interview with her on our blog. There, Michelle writes, "I've discovered that really my favorite ocean is the one I can currently dip my toes into. I find there's something so calming about the coast, and so humbling. There's no better place to be reminded of our own beautiful smallness." As this issue took shape, I realized that I wanted it to begin with the ocean itself. Thanks to Michelle, it does—she took the photo shown on the facing page at what's now called Topsail Beach. From this body of water to the one you're closest to...

Improved GPU/CUDA Based Parallel Weather and Research Forecast (WRF) Single Moment 5-Class (WSM5) Cloud Microphysics

The Weather Research and Forecasting (WRF) model is an atmospheric simulation system which is designed for both operational and research use. WRF is currently in operational use at the National Oceanic and Atmospheric Administration (NOAA)'s national weather service as well as at the air force weather agency and meteorological services worldwide. Getting weather predictions in time using latest advances in atmospheric sciences is a challenge even on the fastest super computers. Timely weather predictions are particularly useful for severe weather events when lives and property are at risk. Microphysics is a crucial but computationally intensive part of WRF. WRF Single Moment 5-class (WSM5) microphysics scheme represents fallout of various types of precipitation, condensation and thermodynamics effects of latent heat release. Therefore, to expedite the computation process, Graphics Processing Units (GPUs) appear an attractive alternative to traditional CPU architectures. In this paper, we accelerate the WSM5 microphysics scheme on GPUs and obtain a considerable speedup thereby significantly reducing the processing time. Such high performance and computationally efηcient GPUs allow us to use higher resolution WRF forecasts. The use of high resolution WRF enables us to compute microphysical processes for increasingly small clouds and water droplets. To implement WSM5 scheme on GPUs, the WRF code was rewritten into CUDA C, a high level data-parallel programming language used on NVIDIA GPU. We observed a reduction in processing time from 16928 ms on CPU to 43.5 ms on a Graphics Processing Unit (GPU). We obtained a speedup of 389× without I/O using a single GPU. Taking I/O transfer times into account, the speedup obtained is 206×. The speedup was further increased by using four GPUs, speedup being 1556× and 357× for without I/O and with I/O, respectively.

What do the cited and citing environments reveal about Advances in Atmospheric Physics?

The networking status of journals reflects their academic influence among peer journals. This paper analyzes the cited and citing environments of this journal, Advances in Atmospheric Sciences (Adv. Atmos. Sci.), using methods from social network analysis. Since its initial publication, Adv. Atmos. Sci. has been actively participating in the international journal environment and international journals are frequently cited in Adv. Atmos. Sci. Particularly, this journal is intensely interrelated with its international peer journals in terms of their similar citing patterns. The international influence of Adv. Atmos. Sci. is comparatively bigger than other Chinese SCI journals in atmospheric sciences as reflected by total cites to Adv. Atmos. Sci. and the total number of international journals citing it. The academic visibility of Adv. Atmos. Sci. is continuing to improve in the international research community as the number of reference citation it receives in its peer journals internationally increases over time.

This third-order accuracy is kept even in non-uniform grid, while the cubic Lagrange becomes the first order. The semi-Lagrangian approach to the characteristic equations has been used for solving gravity waves because it can make time step be much longer than the Courant-Friedrichs-Lewy (CFL) condition. Even in two dimensions, the method can give a symmetrical wave propagation under the large CFL condition. References T. Yabe, F. Xiao and T. Utsumi, J. Comput. Phys. 169, 556 (2001).

A personal perspective on the further reform of the advances in atmospheric sciences

First of all, I wish to thank the Advances in Atmospheric Sciences (AAS) Editorial Board for recommending the publication of this original letter, summarizing my personal perspective on the reform of AAS, that was distributed during its 19 December 2001 Board meeting. The letter has now been significantly improved by the incorporation of many helpful comments and suggestions from extensive email discussions conducted among over 60 foreign participants, including several board members of AAS, as well as from numerous personal communications (see the acknowledgements section).
