Using WRF Downscaling and Self-Organising Maps to Investigate Particulate Pollution in the Sydney Region
Using WRF downscaling and self-organising maps to investigate particulate pollution in the Sydney region. Supplementary Information JAGODA CRAWFORD, ALAN GRIFFITHS1, DAVID D. COHEN1, NINGBO JIANG2, EDUARD STELCER1 1Australian Nuclear Science and Technology Organisation, Locked Bag 2001 Kirrawee DC NSW 2232, Australia 2Office of Environment and Heritage, NSW Department of Premier and Cabinet, Sydney, Australia 1 Corresponding author. Tel: +61 2 9717 3885, Fax: +61 2 9717 9260; e-mail [email protected] 1 The Weather Research and Forecasting model (WRF) The Advanced Research (AR) WRF (WRF hereafter) model version 3.5.1 (Skamarock et al., 2004; Skamarock and Klemp, 2008) was used to carry out meteorological dynamical downscaling. The main advantages of using dynamical downscaling is that some processes which are on subgrid scales in the global model will be simulated explicitly by the regional model and more frequent output intervals can be specified. If the regional model simulates sea breezes and the influence of topography more realistically, trajectories computed from its output will also be more accurate. A vast number of WRF configuration options are possible. The current configuration is similar to that used by Angevine et al. (2013). The model was configured with 12 km horizontal resolution, 50 vertical levels, with greatly enhanced resolution near the surface (half of the levels below 1 km and a 20 m thick near-surface level). Subgrid vertical turbulence was modelled with the Mellor-Yamada-Janjic (MYJ) boundary layer and surface layer schemes (Janjić, 1994), longwave and shortwave radiation was modelled with RRTMG (Iacono et al., 2008), cloud microphysics was modelled with the Lin (Purdue) scheme (Lin et al., 1983) and subgrid moist cumulus was modelled using the Grell-Freitas scheme (Grell and Freitas, 2014). -

Why No Wonder Woman?
Why No Wonder Woman? A REPORT ON THE HISTORY OF WONDER WOMAN AND A CALL TO ACTION!! Created for Wonder Woman Fans Everywhere Introduction by Jacki Zehner with Report Written by Laura Moore April 15th, 2013 Wonder Woman - p. 2 April 15th, 2013 AN INTRODUCTION AND FRAMING “The destiny of the world is determined less by battles that are lost and won than by the stories it loves and believes in” – Harold Goddard. I believe in the story of Wonder Woman. I always have. Not the literal baby being made from clay story, but the metaphorical one. I believe in a story where a woman is the hero and not the victim. I believe in a story where a woman is strong and not weak. Where a woman can fall in love with a man, but she doesnʼt need a man. Where a woman can stand on her own two feet. And above all else, I believe in a story where a woman has superpowers that she uses to help others, and yes, I believe that a woman can help save the world. “Wonder Woman was created as a distinctly feminist role model whose mission was to bring the Amazon ideals of love, peace, and sexual equality to ʻa world torn by the hatred of men.ʼ”1 While the story of Wonder Woman began back in 1941, I did not discover her until much later, and my introduction didnʼt come at the hands of comic books. Instead, when I was a little girl I used to watch the television show starring Lynda Carter, and the animated television series, Super Friends. -

A, AIR & SPA ID SE CE MU REP SEU INT M AIRCRAFT COLLECTION From the Avenger torpedo bomber, a stalwart from Intrepid’s World War II service, to the A-12, the spy plane from the Cold War, this collection reflects some of the GREATEST ACHIEVEMENTS IN MILITARY AVIATION. Photo: Liam Marshall TABLE OF CONTENTS Bombers / Attack Fighters Multirole Helicopters Reconnaissance / Surveillance Trainers OV-101 Enterprise Concorde Aircraft Restoration Hangar Photo: Liam Marshall BOMBERS/ATTACK The basic mission of the aircraft carrier is to project the U.S. Navy’s military strength far beyond our shores. These warships are primarily deployed to deter aggression and protect American strategic interests. Should deterrence fail, the carrier’s bombers and attack aircraft engage in vital operations to support other forces. The collection includes the 1940-designed Grumman TBM Avenger of World War II. Also on display is the Douglas A-1 Skyraider, a true workhorse of the 1950s and ‘60s, as well as the Douglas A-4 Skyhawk and Grumman A-6 Intruder, stalwarts of the Vietnam War.

Originally built as the TBF by Grumman Aircraft Engineering Corporation, they were affectionately nicknamed “Turkeys” for their somewhat ungainly appearance. Bomber Torpedo In 1943 Grumman was tasked to build the F6F Hellcat fighter for the Navy. -

Appendix B Characteristics and Analysis of Flares
APPENDIX B CHARACTERISTICS AND ANALYSIS OF FLARES 1.0 Introduction The F-15E and F-15C employ MJU-7 A/B and MJU-10/B self-protection flares in approved airspace over parts of Alaska. The F-22A uses MJU-10/B self-protection flares. Self-protection flares are magnesium pellets that, when ignited, burn for 3.5 to 5 seconds at 2,000 degrees Fahrenheit. The burn temperature is hotter than the exhaust of an aircraft, and therefore attracts and decoys heat-seeking weapons targeted on the aircraft. Flares are used in pilot training to develop the near instinctive reactions to a threat that are critical to combat survival. This appendix describes flare composition, ejection, risks, and associated regulations. 2.0 Flare Composition Self-protection flares are primarily mixtures of magnesium and Teflon (polytetrafluoroethylene) molded into rectangular shapes (United States Air Force [Air Force] 1997). Longitudinal grooves provide space for materials that aid in ignition such as: • First fire materials: potassium perchlorate, boron powder, magnesium powder, barium chromate, Viton A, or Fluorel binder. • Immediate fire materials: magnesium powder, Teflon, Viton A, or Fluorel • Dip coat: magnesium powder, Teflon, Viton A or Fluorel Typically, flares are wrapped with an aluminum-coated mylar or filament-reinforced tape (wrapping) and inserted into an aluminum (0.03 inches thick) case that is closed with a felt spacer and a small plastic end cap (Air Force 1997). The top of the case has a pyrotechnic impulse cartridge that is activated electrically to produce hot gases that push a piston, the flare material, and the end cap out of the aircraft into the airstream. -
7. Transonic Aerodynamics of Airfoils and Wings
W.H. Mason 7. Transonic Aerodynamics of Airfoils and Wings 7.1 Introduction Transonic flow occurs when there is mixed sub- and supersonic local flow in the same flowfield (typically with freestream Mach numbers from M = 0.6 or 0.7 to 1.2). Usually the supersonic region of the flow is terminated by a shock wave, allowing the flow to slow down to subsonic speeds. This complicates both computations and wind tunnel testing. It also means that there is very little analytic theory available for guidance in designing for transonic flow conditions. Importantly, not only is the outer inviscid portion of the flow governed by nonlinear flow equations, but the nonlinear flow features typically require that viscous effects be included immediately in the flowfield analysis for accurate design and analysis work. Note also that hypersonic vehicles with bow shocks necessarily have a region of subsonic flow behind the shock, so there is an element of transonic flow on those vehicles too. In the days of propeller airplanes the transonic flow limitations on the propeller mostly kept airplanes from flying fast enough to encounter transonic flow over the rest of the airplane. Here the propeller was moving much faster than the airplane, and adverse transonic aerodynamic problems appeared on the prop first, limiting the speed and thus transonic flow problems over the rest of the aircraft. However, WWII fighters could reach transonic speeds in a dive, and major problems often arose. One notable example was the Lockheed P-38 Lightning. Transonic effects prevented the airplane from readily recovering from dives, and during one flight test, Lockheed test pilot Ralph Virden had a fatal accident. -
