Abstract Effects of internal gravity waves on stably stratified atmospheric turbulence is studied in the framework of the energy- and flux-budget (EFB) turbulence closure model. We take into account for additional vertical flux of momentum and additional productions of turbulent kinetic energy (TKE), turbulent potential energy (TPE) and turbulent flux of potential temperature caused by large-scale internal gravity waves (IGW). For the stationary, homogeneous regime, the EFB closure model without large-scale IGW yields universal dependencies of the flux Richardson number, turbulent Prandtl number, energy ratios, and normalised vertical fluxes of momentum and heat on the gradient Richardson number, Ri. Due to the large-scale IGW, these dependencies lose their universality. The maximal value of the flux Richardson number (universal constant 0.2-0.25 in the no-IGW regime) becomes strongly variable. In the vertically homogeneous stratification, it increases with increasing wave energy and can even exceed 1. In the heterogeneous stratification, when IGW propagate towards stronger stratification, the maximal flux Richardson number decreases with increasing wave energy, reaches zero and then becomes negative. This implies that the vertical flux of potential temperature becomes counter-gradient. IGW also reduce anisotropy of turbulence: in contrast to the mean wind shear, which generates only horizontal TKE, IGW generate both horizontal and vertical TKE. IGW also increase the share of TPE in the turbulent total energy (TTE = TKE + TPE). A well-known effect of IGW is their direct contribution to the vertical transport of momentum. Depending on the direction (downward or upward), IGW either strengthen or weaken the total vertical flux of momentum. We also included in the EFB closure model the budget equations for the kinetic and potential energies for IGW that determine the energy transport by the waves. The analysis of the solution of the derived nonlinear equations shows that IGW with the larger initial energy have a shorter damping length. Predictions from the proposed model are consistent with available data from atmospheric and laboratory experiments, direct numerical simulations and large-eddy simulations.

Abstract Time series analysis is one of the primary tools utilized by oceanographers for studying in situ data and model output. However, there is a significant gap between the magnitude of the analysis tasks facing the community today, and the capabilities of our traditional methods. New methods are needed for new lines of inquiry. This talk provides a tutorial introduction to a series of major recent advances in stationary and nonstationary time series analysis for oceanographic applications, with practical examples. Much of this work was carried out by the author over a number of years, building on modern signal processing concepts that are not yet widely known in the oceanographic community. Topics covered include: fundamentals of optimal spectral analysis; uses and abuses of the wavelet transform; theory of time-varying covariance; analysis of quasi-periodic oscillations; new classes of parametric stochastic models; and empirical orthogonal functions for bivariate data. The analysis algorithms described herein are distributed to the community as a part of a large software toolbox called JLAB, written by the author and available at http://www.jmlilly.net/jmlsoft.html.

Time and place Mon 20 Apr 2015, 13.15 Room C609, Arrhenius Laboratory, 6th floor Welcome! Abstract Studies of biological processes in the ocean tend to focus on specific domains in time and space, often in combination with rather limiting assumptions about marine ecosystems. Such approaches are constructive for certain scientific questions, but fail to provide a more general understanding. This presentation discusses some new approaches to bridge different scales by exploring how properties such as sea surface temperature, chlorophyl, l or Net Community Production (NCP) are distributed in time and space. One example is to what extent changes in phytoplankton biomass is episodic or more uniform.

Although highly subjective and explorative, this talk will be structured into five partly interrelated forefront items: i) after crossdating, ii) beyond forests, iii) towards history, iv) below surface, and v) inside rings. About Ulf Büntgen Dr. Ulf Büntgen is Head of the Dendroecology Group at the Swiss Federal Research Institute for Forest, Snow & Landscape (WSL), Switzerland. He is also Associated Research Fellow of Oeschger Centre for Climate Change Research, University of Bern, Switzerland and Associated Senior Scientist at Global Change Research Centre AS CR, Brno, Czech Republic. All his studies focus on providing answers to his two main research questions: How did and does climate change? How did and do ecosystems respond to such changes?

After experiments demonstrated that this resulted from electric coupling, the conductors were found to be long, multicellular, filamentous bacteria, now known as cable bacteria. In this talk I will review our current knowledge on the cable bacteria and their role and distribution in nature. Fine scale potentiometric based techniques allow us to address cable bacteria activity in situ, and unravel their abundance in nature. Geochemical investigations and modelling gives insight into their impact on the environment and the properties of electron conduction. Genome analysis, microscopy and isotope labelling experiments provide preliminary insight into the physiology and behavior of the organisms. Though research efforts have provided new and surprising insight into the role and function of the cable bacteria many open questions are still left. -------------- next part -------------- An HTML attachment was scrubbed...

Bolin Centre Seminar Speaker: Geoff Vallis, University of Exeter (UK) Title: Theory of the deep ocean circulation and draw-down of CO2 at the Last Glacial Maximum. Time: Thursday 7 May at 13.30 in Ahlmannsalen, Geohuset Abstract: Two longstanding problems in Earth System Science are (i) To understand the deep circulation of ocean and (ii) To understand why CO2 levels during ice ages, and in particular at the Last Glacial Maximum (LGM), were so much lower than today. I will try to show that a new theory of (i) can lead to a solution of (ii). Over the past decade or so our understanding of the meridional overturning circulation (MOC) of the ocean has gone through something of a transformation. Rather than being a purely buoyancy-driven circulation, we now believe it to be, at least in part, driven by winds, with those over the Southern Ocean playing a particular role. I'll discuss these developments and present a semi-analytic theory -- that is, a testable conceptual model -- of the oceanic MOC. If we then add a carbon cycle to this model, and change the boundary conditions to be appropriate for glacial conditions, we find a natural explanation for the draw down of carbon dioxide during ice ages. (Joint work with Max Nikurashin and Andy Watson.) About Geoff Vallis: Geoff is one of the world's foremost experts on atmosphere and ocean fluid dynamics.
