Die Eisverhältnisse des Winters 1952/53 an den deutschen Küsten zwischen Ems und Trave     

Franz Nusser 《Ocean Dynamics》1955,8(2):65-72

Zusammenfassung Der Winter 1952/53 war an den deutschen Küsten ein mä\iger Eiswinter. Innerhalb der Winter von 1896/97 bis 1952/53 nimmt er nach seinem Eisausma\ gerade den Zentralwert ein. Während des Winters war die méridionale Luftzirkulation vorherrschend, aber auch der Anteil der zonalen Zirkulation war nicht gering. Unter den Gro\wetterlagen überwogen das abgeschlossene Hoch über Mitteleuropa und die Hochdruckbrücke über Mitteleuropa. Der Winter hatte vier Eisperioden, von denen die zweite nur andeutungsweise auftrat, während die letzte das meiste Eis brachte.

Ice conditions on the German coasts between the rivers Ems and Trave during the winter 1952/53

Summary The winter 1952/53 on the German coasts was a moderate ice winter. Because of the extent of its ice formation it occupies the central value among the winters from 1896/97 up to 1952/53. During this winter, meridional atmospheric circulation predominated, though the part that fell to zonal circulation was not inconsiderable either. Among the large scale weather situations, the closed high pressure area and the ridge of high pressure over Central Europe were preponderant. There were four periods of ice formation of which the second period was but very insignificant, while the greatest ice production was observed during the last cold period.

Rapport sur les conditions des glaces sur les cÔtes allemandes entre l'Ems et le Trave pendant l'hiver 1952/53

Résumé L'hiver 1952/53 sur les cÔtes allemandes montrait un caractère modéré. Parmi les hivers de la période de 1896/97 jusqu'à 1952/53 il occupe justement la valeur centrale à cause de la grandeur de sa production des glaces. Pendant cet hiver, la circulation atmosphérique méridionale prédominait, mais la part de la circulation zonale n'était pas petite non plus. Parmi les situations météorologiques générales, l'aire concentrée de haute pression et la dorsale de haute pression au dessus de l'Europe Central étaient prépondérantes. Il y avait quatre périodes des glaces pendant cet hiver; au cours da la seconde période la production des glaces était insignifiicante tandis que la dernière période était caractérisée par la plus forte formation des glaces.

Comparison of the SFI peculiar velocities with the IRAS 1.2-Jy gravity field     

Luiz N. da Costa  Adi Nusser  Wolfram Freudling  Riccardo Giovanelli  Martha P. Haynes  John J. Salzer  & Gary Wegner 《Monthly notices of the Royal Astronomical Society》1998,299(2):425-432

We present a comparison between the peculiar velocity fields measured from a recently completed l -band Tully–Fisher survey of field spirals (SFI) and that derived from the IRAS 1.2-Jy redshift survey galaxy distribution. The analysis is based on the expansion of these data in redshift space using smooth orthonormal functions, and is performed using low- and high-resolution expansions, with an effective smoothing scale which increases almost linearly with redshift. The effective smoothing scales at 3000 km s⁻¹ are 1500 and 1000 km s⁻¹ for the low- and high-resolution filters. The agreement between the high- and low-resolution SFI velocity maps is excellent. The general features in the filtered SFI and IRAS velocity fields agree remarkably well within 6000 km s⁻¹. This good agreement between the fields allows us to determine the parameter β = Ω^0.6 / b , where Ω is the cosmological density parameter, and b is the linear biasing factor. From a likelihood analysis on the SFI and IRAS modes we find that β = 0.6 ± 0.1, independently of the resolution of the modal expansion. For this value of β, the residual fields for the two filters show no systematic variations within 6000 km s⁻¹. Most remarkable is the lack of any coherent, redshift-dependent dipole flow in the residual field.  相似文献

General relativistic self-similar solutions in cosmology     

Adi Nusser 《Monthly notices of the Royal Astronomical Society》2007,375(3):1106-1110

We present general relativistic solutions for self-similar spherical perturbations in an expanding cosmological background of cold pressure-less gas. We focus on solutions having shock discontinuities propagating in the surrounding cold gas. The pressure, p , and energy density, μ, in the shock-heated matter are assumed to obey   p = w μ  , where w is a positive constant. Consistent solutions are found for shocks propagating from the symmetry centre of a region of a positive density excess over the background. In these solutions, shocks exist outside the radius marking the event horizon of the black hole which would be present in a shock-less collapse. For large jumps in the energy density at the shock, a black hole is avoided altogether and the solutions are regular at the centre. The shock-heated gas does not contain any sonic points, provided the motion of the cold gas ahead of the shock deviates significantly from the Hubble flow. For shocks propagating in the uniform background, sonic points always appear for small jumps in the energy density. We also discuss self-similar solutions without shocks in fluids with   w < −1/3  .  相似文献   

U-series and oxygen isotope chronology of the mid-Pleistocene Lake Amora (Dead Sea basin)     

Adi Torfstein  Alexandra Haase-Schramm  Nicolas Waldmann  Mordechai Stein 《Geochimica et cosmochimica acta》2009,73(9):2603-2630

This study establishes for the first time the chronology and limnological history of Lake Amora (Dead Sea basin, Israel), whose deposits (the Amora Formation) comprise one of the longest exposed lacustrine records of the Pleistocene time. The Amora Formation consists of sequences of laminated primary aragonite and silty-detritus, Ca-sulfate minerals, halite and clastic units. This sedimentary sequence was uplifted and tilted by the rising Sedom salt diapir, exposing ∼320 m of sediments on the eastern flanks of Mt. Sedom (the Arubotaim Cave (AC) section).The chronology of the AC section is based on U-disequilibrium dating (²³⁰Th-²³⁴U and ²³⁴U-²³⁸U ages) combined with floating δ¹⁸O stratigraphy and paleomagnetic constraints. The determination of the ²³⁰Th-²³⁴U ages required significant corrections to account for detrital Th and U. These corrections were performed on individual samples and on suites of samples from several stratigraphic horizons. The most reliable corrected ages were used to construct an age-elevation model that was further tuned to the oxygen isotope record of east Mediterranean foraminifers (based on the long-term similarity between the sea and lake oxygen isotope archives).The combined U-series-δ¹⁸O age-elevation model indicates that the (exposed) Amora sequence was deposited between ∼740 and 70 ka, covering seven glacial-interglacial cycles (Marine Isotope Stages (MIS) 18 to 5).Taking the last glacial Lake Lisan and the Holocene Dead Sea lacustrine systems as analogs of the depositional-limnological environment of Lake Amora, the latter oscillated between wet (glacial) and more arid (interglacial) conditions, represented by sequences of primary evaporites (aragonite and gypsum that require enhanced supply of freshwater to the lakes) and clastic sediments, respectively. The lake evolved from a stage of rapid shifts between high and low-stand conditions during ∼740 to 550 ka to a sabkha-like environment that existed (at the AC site) between 550 and 420 ka. This stage was terminated by a dry spell represented by massive halite deposition at 420 ka (MIS12-11). During MIS10-6 the lake fluctuated between lower and higher stands reaching its highest stand conditions at the late glacial MIS6, after which a significant lake level decline corresponds to the transition to the last interglacial (MIS5) low-stand lake, represented by the uppermost part of the Formation.δ¹⁸O values in the primary aragonite range between 6.0 and −1.3‰, shifting cyclically between glacial and interglacial intervals. The lowest δ¹⁸O values are observed during interglacial stages and may reflect short and intense humid episodes that intermittently interrupted the overall arid conditions. These humid episodes, expressed also by enhanced deposition of travertines and speleothems, seem to characterize the Negev Desert, and in contrast to the overall dominance of the Atlantic-Mediterranean system of rain patterns in the Dead Sea basin, some humid episodes during interglacials may be traced to southern sources.  相似文献   

Neutralino annihilations and the gas temperature in the dark ages     

Zacharia Myers  Adi Nusser 《Monthly notices of the Royal Astronomical Society》2008,384(2):727-732

Assuming that the dark matter is entirely made up of neutralinos, we re-visit the role of their annihilation on the temperature of diffuse gas in the high-redshift universe  ( z > 10)  , before the formation of luminous structures. We consider neutralinos of particle mass 36 and 100 GeV. The former is able to produce  ∼7  e ⁻ e ⁺  particles per annihilation through the fremionic channel, and the latter ∼53 particles assuming a purely bosonic channel. High-energy   e ⁻ e ⁺  particles up-scatter the cosmic microwave background (CMB) photons into higher energies via the inverse-Compton scattering. The process produces a power-law   e ⁻ e ⁺  energy spectrum of index −1 in the energy range of interest, independent of the initial energy distribution. The corresponding energy spectrum of the up-scattered photons is a power law of index −1/2, if absorption by the gas is not included. The scattered photons photoheat the gas by releasing electrons which deposit a fraction (14 per cent) of their energy as heat into the ambient medium. For uniformly distributed neutralinos, the heating is insignificant. The effect is greatly enhanced by the clumping of neutralinos into dense haloes. We use a time-dependent clumping model which takes into account the damping of density fluctuations on mass-scales smaller than  ∼10⁻⁶ M_⊙  . With this clumping model, the heating mechanism boosts the gas temperature above that of the CMB after a redshift of   z ∼ 30  . By   z ≈ 10  , the gas temperature is nearly 100 times its temperature when no heating is invoked. Similar increase is obtained for the two neutralino masses considered.  相似文献
