    Description: Pacific Ocean western boundary currents and the interlinked equatorial Pacific circulation system were among the first currents of these types to be explored by pioneering oceanographers. The widely accepted but poorly quantified importance of these currents-in processes such as the El Nino/Southern Oscillation, the Pacific Decadal Oscillation and the Indonesian Throughflow-has triggered renewed interest. Ongoing efforts are seeking to understand the heat and mass balances of the equatorial Pacific, and possible changes associated with greenhouse-gas-induced climate change. Only a concerted international effort will close the observational, theoretical and technical gaps currently limiting a robust answer to these elusive questions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Dunxin -- Wu, Lixin -- Cai, Wenju -- Gupta, Alex Sen -- Ganachaud, Alexandre -- Qiu, Bo -- Gordon, Arnold L -- Lin, Xiaopei -- Chen, Zhaohui -- Hu, Shijian -- Wang, Guojian -- Wang, Qingye -- Sprintall, Janet -- Qu, Tangdong -- Kashino, Yuji -- Wang, Fan -- Kessler, William S -- England -- Nature. 2015 Jun 18;522(7556):299-308. doi: 10.1038/nature14504.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Key Laboratory of Ocean Circulation and Waves, Institute of Oceanology, Chinese Academy of Sciences, Qingdao 266071, China. ; Physical Oceanography Laboratory, Qingdao Collaborative Innovation Center of Marine Science and Technology, Ocean University of China, Qingdao 266003, China. ; 1] Physical Oceanography Laboratory, Qingdao Collaborative Innovation Center of Marine Science and Technology, Ocean University of China, Qingdao 266003, China [2] CSIRO Oceans and Atmosphere Flagship, Aspendale, Victoria 3195, Australia. ; Australian Research Council (ARC) Centre of Excellence for Climate System Science, Mathews Building, The University of New South Wales, Sydney 2052, Australia. ; Institut de Recherche pour le Developpement (IRD), UMR5566-LEGOS, UPS (OMP-PCA), 31400 Toulouse, France. ; Department of Oceanography, University of Hawaii at Manoa, 1000 Pope Road, Honolulu, Hawaii 96822, USA. ; Lamont-Doherty Earth Observatory, Earth Institute at Columbia University, Palisades, New York 10964, USA. ; CSIRO Oceans and Atmosphere Flagship, Aspendale, Victoria 3195, Australia. ; Scripps Institution of Oceanography, 9500 Gilman Drive, La Jolla, California 92037, USA. ; IPRC, Department of Oceanography, SOEST, University of Hawaii, Honolulu, Hawaii 96822, USA. ; Center for Earth Information Science and Technology, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) 3173-25 Showa-machi Kanazawa-ku, Yokohama 236-0001, Japan. ; NOAA/Pacific Marine Environmental Laboratory, Seattle, Washington 98115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26085269" target="_blank"〉PubMed〈/a〉

    Notes: The propagation of undamped transverse thermal waves in a layer of binary mixture is investigated. It is shown that when the thermal diffusivity KT is equal to the mass diffusivity KS, such waves do not exist. But when KT〉KS, these waves may exist provided the layer is heated from below (such that thermohaline instability does not occur) and the concentration of the solute in the mixture decreases vertically upward. The analysis also reveals the interesting result that when KT〈KS, undamped waves can propagate even if the layer is heated from above provided the concentration increases vertically upward. It is further shown that as in a homogeneous fluid, weakly damped low-frequency waves can propagate and the regions in the parameter space where such propagation is possible are delineated. High-frequency waves are shown to be always strongly damped.

    Description / Table of Contents: Zusammenfassung In dieser Veröffentlichung wird die Stabilität von langen Wellen mit endlicher Amplitude in der Schicht einer Flüssigkeit zweiter Ordnung diskutiert, die längs einer geneigten Ebene abfließt. Es wird ein systematisches Entwicklungsverfahren nach einem Parameterµ angegeben, der das Verhältnis der ungestörten Schichtdicke zu einer repräsentativen Länge längs der Ebene beschreibt, und es werden Lösungen bis zur OrdnungO(µ 3) erhalten. Man findet, daß schwach nicht-lineare monochromatische Wellen für Weber-Zahlen der OrdnungO(µ −2) einem Gleichgewichtszustand zustreben. Die Gleichgewichtsamplitude nimmt mit wachsendem elastischem ParameterM zuerst zu, erreicht ein Maximum und fällt dann mitM wieder ab. Es wird schließlich noch gezeigt, daß sich die Flüssigkeit zweiter Ordnung wie eine newtonsche Flüssigkeit verhält, deren Viskosität jedoch durch Division durch einen Faktor 1 + (5M/2) reduziert ist.
    Notes: Summary In this paper the finite amplitude stability of long waves on a layer of a second-order fluid flowing down an inclined plane is discussed. A systematic expansion procedure in terms of a parameterµ, which is the ratio of the undisturbed layer thickness to a representative length down the plane, is developed and solutions are obtained toO(µ 3). It is found that weakly non-linear monochromatic waves tend to attain equilibrium states for Weber numbers ofO(µ −2). This equilibrium amplitude first increases with increase in the elastic parameterM, reaches a maximum and then decreases withM. It is also shown that the second fluid behaves like a Newtonian fluid with its viscosity reduced through division by the factor 1 + (5M/2).

    Notes: Abstract The transient flow in the Ekman layer of an elastico-viscous liquid near a flat plate is discussed. Initially the fluid and the plate were rotating together and the plate then suddently starts moving with a uniform velocity in its own plane relative to the rotating frame of reference. It is shown that the ultimate steady state is reached through decay of inertial oscillations whose frequency decreases with increase in the elastic parameter.

    Notes: Abstract We study the linear stability of nondissipative flow of an electrically conducting fluid subject to non-axisymmetric disturbances in the following cases: (i) the radial flow of an incompressible fluid between two concentric porous circular cylinders in the presence of a radial magnetic field and (ii) axial flow of a compressible fluid between two concentric circular cylinders permeated by a helical magnetic field (0,B 0θ(r),B 0z) in a cylindrical coordinate system. It is shown that in case (i), the flow is stable if the Alfvén velocity based on the undisturbed radial magnetic field exceeds the radial velocity due to suction or injection at the cylinder surfaces. In case (ii), it is found that under certain conditions the complex wave speed for an unstable mode lies within a circle of diameterW max-W min, whereW max andW min are the maximum and minimum values of the axial velocity in the flow region. In the presence of a purely axial magnetic field, however, the complex wave speed for an unstable mode always lies within the above circle.

    Notes: Summary The development of a compressible boundary layer over a wedge impulsively set into motion is studied in this paper. The initial motion is independent of the leading edge effect and the solutions are those of a Rayleigh-type problem. The motion tends to an ultimate steady state of Falkner-Skan type. The equations governing the transient boundary layer from the initial steady state to the terminal steady-state change their character after certain time due to the leading edge effect and thereafter solution depends on both the end conditions. Numerical solutions are obtained through the second-order accuracy upwind scheme. The effects of the Falkner-Skan parameter and the surface temperature on the transient flow and heat transfer are also studied. It has been found that the flow separation does not occur form≧−0.0707 when θ w = 1.5 (hot wall), andm≧−0.118 when θ 0.5 (cold wall).

    Description / Table of Contents: Summary The flow of an incompressible fluid of second grade past an infinite porous plate subject to either suction or blowing at the plate is studied. It is found that existence of solutions is tied in with the sign of material moduli and in marked contrast to the Classical Newtonian, fluid solutions can be exhibited for the blowing problem.
    Notes: Sommario Si studia la corrente di un fluido incomprimibile di secondo grado che lambisce una lastra porosa da cui è succhiato o soffiato. Si trova che l'esistenza delle soluzioni è legata al segno dei moduli del materiale e, in netto contrasto col fluido newtoniano classico, si possono trovare soluzioni per il problema del soffiamento.
