THE INTERFACE EFFECT AND THE FORmATION OF A LOW-LEVEL JET ALONG THE EAST SIDE OF THE ROCKY mOUNTAINS

引用

Advances in Atmospheric Sciences 1987年第2期4卷 175-184页

作者：周军,walter K. Henry Nanjing Institute of meteorology Nanjing Texas A & m University College Station TX 77843-3146 U.S.A.

Based upon the analysis of several different causes for the low-level jet along the east side of the Rocky mountains, the concept of "Interface Effect" is established. The basic mechanism for the formation of the low-level jet in North America has been found to be the compression and divergence, under the driving of ageostrophic winds, of the air columns between two surfaces-the ground and the bottom of inversion-which slope with different patterns in a cross-section normal to the jet stream. As a result, the air parcel is accelerated along the streamline and the anticyclonic shear of the current increased. Also, the diurnal variation of the jet is determined by the interface effect.

mass asymmetry and tricyclic wobble motion assessment using automated launch video analysis

Defence Technology（防务技术） 2016年第2期12卷 113-116页

作者： Ryan DECKER Joseph DONINI William GARDNER Jobin JOHN walter KOENIG Armaments Research Design and Engineering CenterPicatinny Arsenal

This paper describes an approach to identify epicyclic and tricyclic motion during projectile flight caused by mass asymmetries in spinstabilized projectiles. Flight video was captured following projectile launch of several m110A2E1 155 mm artillery projectiles. These videos were then analyzed using the automated flight video analysis method to attain their initial position and orientation *** of the pitch and yaw histories clearly indicates that in addition to epicyclic motion's nutation and precession oscillations, an even faster wobble amplitude is present during each spin revolution, even though some of the amplitudes of the oscillation are smaller than 0.02 *** results are compared to a sequence of shots where little appreciable mass asymmetries were present, and only nutation and precession frequencies are predominantly apparent in the motion history results. magnitudes of the wobble motion are estimated and compared to product of inertia measurements of the asymmetric projectiles.

An unsettling explanation for the failure of skatole-baited ovitraps to capture Culex mosquitoes

Culex mosquitoes are primarily found in temperate and tropical regions worldwide where they play a crucial role as main vectors of filarial worms and arboviruses. In Recife, a northeast city in Brazil, high densities of Culex quinquefasciatus are often found in association with human populated areas. In marked contrast to another part of the city, field tests conducted in the neighborhood of Sitio dos Pintos showed that trapping of mosquitoes in skatole-baited ovitraps did not differ significantly from captures in control (water) traps. Thus, classical and molecular taxonomic approaches were used to analyze the Culex species circulating in Sitio dos Pintos. Results obtained from both approaches agreed on the cocirculation of Culex quinquefasciatus and Culex nigripalpus in three different areas of this neighborhood. What was initially considered as an unexpected failure of this lure turned out to be a more unsettling problem, that is, the first report in Recife of Culex nigripalpus, a vector of Venezuelan equine encephalitis virus and West Nile virus. Unplanned urbanization processes close to remnants of the Atlantic forest, such as observed in Sitio dos Pintos, may have contributed to the introduction of Cx. nigripalpus in urban areas.

Submicron particle-bound polycyclic aromatic hydrocarbons in the Polish teaching rooms： Concentrations, origin and health hazard

The goal of the work was to investigate the concentrations of the 16 US EPA priority polycyclic aromatic hydrocarbons（PAH） bound to submicrometer particles（particulate matter, Pm1） suspended in the air of university teaching rooms and in the atmospheric air outside. Two teaching rooms were selected in two Polish cities, Gliwice, southern Poland,and Warsaw, central Poland, differing with regard to the ambient concentrations and major sources of Pm and PAH. The variabilities of indoor and outdoor 24-hr concentrations of Pm1-bound PAH, the ratio（I/O） of the indoor to outdoor 24-hr concentrations of Pm1-bound PAH, probable sources of PAH and the level of the hazard from the mixture of the 16 PAH（ΣPAH） to humans at both sites were analyzed. In both Warsaw and Gliwice, the mean concentrations of Pm1-bound ΣPAH were slightly higher in the atmospheric air than in the rooms. The indoor and outdoor concentrations of individual PAH in Gliwice were correlated,in Warsaw – they were not. most probably, the lack of the correlations in Warsaw was due to the existence of an unidentified indoor source of gaseous PAH enriching Pm1 in phenanthrene, fluorene, and pyrene. Although the ambient concentrations of Pm1-bound PAH were low compared to the ones observed earlier at both sites, they were much higher than in other urbanized European areas. However, because of low mass share of heavy PAH in ΣPAH, the various indicators of the health hazard from the 16 PAH mixture were low compared to other regions.
