Aquaplanet configurations are a vital component within the climate model hierarchy and provide numerous research benefits, including bridging the knowledge gap between idealized models and comprehensive Earth system models as well as creating a testbed to better understand sensitivities between model dynamics and parametrized physics. Despite their utility, however, aquaplanet options for current Community Atmosphere Model (CAM) versions are neither fully developed nor publicly available.  This project aims to (1) advance the development of fixed sea-surface temperature and slab-ocean aquaplanet configurations for CAM4, CAM5, and next-generation CAM for CESM2, (2) document and publish supporting materials of these configurations for out-of-the-box use, and (3) perform and analyze a modified subset of the baseline Diagnostic, Evaluation and Characterization of Klima (DECK) experiments following the Coupled Model Intercomparison Project (CMIP) version 6 protocols.  In this talk, we review progress on these project goals and discuss preliminary scientific results related to the hydrologic cycle.  Particular focus will be on global and regional precipitation distributions, extremes, and their differences from Earth-like simulations and observations.

In this talk, we will present two separate studies which analyze environmental extremes.

The first study uses two CESM initial condition ensembles to investigate potential changes in extreme precipitation under two climate change scenarios over the contiguous United States. We fit non-stationary generalized extreme value (GEV) models to annual maximum daily precipitation simulated from the 30-member “Large Ensemble” under the RCP8.5 scenario and a 15-member “Medium Ensemble” under the RCP4.5 scenario. We then compare impacts using the 1% annual exceedance probability level, which is the amount of daily rainfall with only a 1% chance of being exceeded in a given year. We also investigate a pattern scaling approach in which we produce predictive GEV distributions of annual precipitation maxima under RCP4.5 given only global mean temperatures for this scenario. We compare results from this less computationally intensive method to those obtained from our GEV model fitted directly to the CESM RCP4.5 output and find that pattern scaling produces reasonable projections. This study is part of a larger project on the Benefits of Reduced Anthropogenic Climate changE (BRACE).

The second study examines the sensitivities of extreme ground-level ozone to meteorological drivers (e.g. air temperature) using quantile regression and a recently-developed method based on maximizing tail dependence. We will present a case study comparing the sensitivities for observed ozone to those we find in WRF-Chem output. Preliminary results show discrepancies between the relationships between the driving meteorological variables and ozone levels between the observations and the WRF-Chem output.

Shedding LIGHT on eddy-induced mixing in an idealized circumpolar current via online particle tracking

Phillip Wolfram

Los Alamos National Laboratory

Abstract:

Many common offline diagnostics, such as Lagrangian particle tracking, will have to be computed online as computing architectures approach Exascale.  I describe development of the online Lagrangian In-situ Global High-performance particle Tracking (LIGHT) diagnostic within the Model for Prediction Across Scales Ocean (MPAS-O) component of the Department of Energy’s Accelerated Climate model for Energy (ACME).  LIGHT is fully parallel and capable of advecating the same number of Lagrangian particles as Eulerian grid cells.  Lagrangian trajectories are used to quantify of mixing due to mesoscale eddies in an idealized circumpolar current.  Meridional diffusivity depth-variability is assessed via space-time dispersion of particle clusters over ten years’ worth of a million particle trajectories.  Diffusivity in the jet is largest near the critical layer supporting mixing suppression and critical layer theory.  However, it attenuates less rapidly with depth in the jet than both eddy velocity and kinetic energy scalings suggest. A mean-eddy scale separation hypothesis is suspect because both nonlinear upper bound and lower bound diffusivity estimates are large and mixing arises from nonlinearity, i.e., eddy-produced initial filamentation that background mean shear further strains to produce enhanced mixing. Nonlinearity accounts for the majority of the total diffusivity. Eddy and mean flow interactions appear to reduce nonlinear upper bound mixing, but for the lower bound enhance diffusivity near the critical layer. Broadly, this work suggests that diffusivity parameterizations accounting for both diffusivity nonlinearity and depth variability are needed.

A climate diagnostic method: covariation of

finite-amplitude wave activity and the zonal

mean flow in the mid-latitude troposphere

Lei Wang

University of Chicago

Abstract: 

Intra-seasonal atmospheric variability is a prediction gap between weather and climate predictions, and is important for skillfully predicting high-impact extreme events. Variations in jet stream are primarily driven by atmospheric waves that cannot be easily quantified by traditional linear theory. Using theory of finite-amplitude wave activity (FAWA), we develop a new zonal momentum-wave activity cycle, as a counterpart of global energy cycle (Lorenz 1955), but with several advantages for climate diagnostics. In midlatitude austral summer, the budget reveals a largely adiabatic, antiphase covariation of FAWA and the mean flow. A marked periodicity is found for FAWA around 20–30 days, consistent with the recently discovered Baroclinic Annular Mode by Thompson and collaborators. Analysis of the ERA-Interim product reveals that the 20-30 day periodicity in FAWA and eddy heat flux is robust only during the warm season. An idealized AGCM is shown to reproduce qualitatively a BAM-like eddy heat flux spectrum only if the zonal-mean state resembles that of the austral summer, which points to an important consequence of the basic state bias in climate simulations. I will also discuss the implications of this framework for the atmospheric wave variability in a changing climate.

With the development of new remote sensing technology, large or even massive spatial datasets covering the globe become available. Statistical analysis of such data is challenging. This manuscript proposes a semiparametric approach to modeling and inference for massive spatial datasets. In particular, a Gaussian process with additive components is considered, with its covariance structure coming from two components: one part is flexible without assuming a specific parametric covariance function but is able to achieve dimension reduction; the second part is parametric and simultaneously induces sparsity. The inference algorithm for parameter estimation and spatial prediction is devised. The resulting spatial prediction method that we call sparsity-induced kriging (SIK), is applied to simulated data and a massive satellite dataset. The results demonstrate the computational and inferential benefits of SIK over competing methods and show that SIK is more flexible and more robust against model misspecification.

What are “EIT waves” and how can we use them?

“EIT waves” are globally-propagating disturbances in the solar corona that remain controversial almost twenty years since they were first observed by the Extreme ultraviolet Imaging Telescope (EIT) onboard the Solar and Heliospheric Observatory (SOHO). Although they were originally interpreted as waves, this assumption has been challenged by opposing observations from different instruments and spacecraft. Many conflicting interpretations have therefore been proposed to explain the phenomenon. The high temporal and spatial resolution observations provided by the Solar Dynamics Observatory (SDO) have revolutionised our understanding of these features and how they evolve through the solar corona. These observations have allowed the development of automated tracking algorithms and better data-driven simulations, which, combined with detailed case studies and statistical analysis of event databases, are leading to a better understanding of “EIT waves”. As a result, we are starting to move beyond a simple investigation of their physical nature, instead using them to study the corona through which they propagate. In this seminar I will discuss the theories proposed to explain “EIT waves”, placing them in the context of the observations available at the time and showing how they have been updated with improved observations and models. We then look towards the future, using a combination of ground and space-based instruments to examine how “EIT waves” may be used to study the structure of the solar corona and infer the properties of their associated coronal mass ejections.

Stellar Atmospheric Models

Our Sun is the only star we can observe with spatial and temporal resolution. But we can't change its mass, age, effective temperature and metallicity to study in which way these parameters affect its thermal structure and the physical processes responsible for it. On the other side, there is a great variety of stars, similar in atmospheric structure to our Sun, for which we can only obtain their spatially integrated spectra at different wavelengths. In this talk we deal with 1D solar atmospheric models as a source of stellar atmosphere models, and the results we can obtain from them.

The traditional surface energy balance (SEB) based on the matching upward and the downward heat energy flux at the air-land interface lacks a proper derivation from the first law of thermodynamics. The thermal energy transfer between the soil and the atmosphere is related to the heat energy balance within the soil layer between the surface and the depth where the soil heat transfer is measured and the atmospheric layer where the heat transfer is dominated by molecular thermal conduction from the surface. Applying the first law of thermodynamics to the two layers jointly at the surface, additional heat energy transfer terms are identified that missed in the traditional SEB and have strong diurnal variations. The most important missing heat energy term in the traditional SEB is associated with the water flow across the soil layer driven by water evaporation at the surface with temperature changes from the relatively steady value down below to the large diurnal varying value at the top. 

Based on the observation from the Cooperative Atmosphere-Surface Exchange Study 1999 (CASES-99) field experiment, the sum of all the missing heat energy terms approximately balances the residual of the traditional SEB. The investigation emphasizes the contribution of the relatively slow molecular thermal conduction in the heat transfer across the air-earth interface, which cannot be replaced by the relatively fast  turbulent mixing in the heat transfer in the atmosphere as commonly practiced in numerical models.

Modelling Submesoscale Dynamics: A New Parameterization for Oceanic Symmetric Instability*

Scott Bachman

University of Cambridge

 

Abstract:

Next-generation ocean models are expected to routinely resolve dynamics at 1/4 degree or smaller, offering new challenges in modelling subgridscale physics. These models are entering a regime where the unresolved turbulence is less constrained by planetary rotation, requiring a paradigm shift in the way modellers construct turbulence closures. Of particular importance is the representation of submesoscale turbulence, occupying O(1-10) km scales, which plays a leading role in setting the stratification of the surface mixed layer and mediating air-sea fluxes. This talk will introduce the submesoscale parameterization problem by presenting a few extant parameterizations, and will focus on a special type of fluid instability for which no parameterization has previously been developed: symmetric instability (SI). The theory and dynamics of SI will be discussed, from which a new parameterization will be proposed. This parameterization is dependent on external forcing by either surface buoyancy loss or down-front winds, which reduce potential vorticity (PV) and lead to conditions favorable for SI. Preliminary testing of the parameterization using a set of idealized models shows that the induced vertical fluxes of passive tracers and momentum are consistent with those from SI-resolving Large Eddy Simulations.

Overview

The 17th annual WRF Users' Workshop will take place at the NCAR's Center Green Campus, Boulder, Colorado, on 27 June to July 1, 2016

Details and the agenda will be posted at a later date.

Call for Papers

The primary objectives for the Users' Workshop are to provide WRF modeling system updates, to discuss model development and issues and to present evaluations and applications of the model. Papers focusing on development and testing of model applications in all areas are especially encouraged. This year we especially seek contributions on scale-aware physics, physics for high resolution applications and novel techiniques shch as cloud computing.

Authors are given the option of requesting either a poster or an oral presentation; however, we strongly encourage authors to consider submissions for a poster presentation, due to time constraints for oral sessions.

To submit an abstract please go to the registration page.

CISL is excited to announce the second course coordinated by The Institute for Mathematics Applied to Geosciences (IMAGe) in the Beyond P-values series.

This three-day course, July 11-13, 2016, will provide an introduction to the theory and methods of Bayesian Statistics. Bayesian Statistics is an emergent area of Statistics applicable to many problems and especially relevant in the context of uncertainty quantification. The course will cover some simple one- and two-parameter problems to provide a flavor for the mechanics of the Bayesian approach. We will then discuss Markov Chain Monte Carlo (MCMC) methods for making inference using more complicated (higher dimensional) models. By the end of the course the partcipants will fit and evaluate models for a dataset of atmospheric CO2 concentrations taken from ice-core measurements. We'll use the open-source statistical software R [https://www.r-project.org/] and the open-source MCMC package that works seamlessly with R called Stan [mc-stan.org/]. The format of the course is hands-on and participants will use their own laptops. 

The lead instructor for the course is Alix Gitelman, Professor of Statistics at Oregon State University. She will be assisted by Nathan Lenssen (Columbia University), Doug Nychka, Philippe Naveau and Dorit Hammerling and others. Seats are limited to 12 participants and to apply, please visit the Bayesian Statistics Application webpage. Please note that the course is only open to staff and visitors working on NCAR's Boulder, CO campuses.

Registration is now open for the 4th Annual Engineering for Climate Extremes Workshop (on July 14, 2016).

The attached flyer and website have more information, or you can register directly at the link below.

https://www.regonline.com/Register/Checkin.aspx?EventID=1827306

The theme of this year’s meeting is “Water-Energy-People” within a context of resilience within coupled natural and social systems.

Societal and climate change, and heterogeneous resource distribution are increasingly highlighting critical vulnerabilities within the WEP system. The interplay of economic and policy drivers with social and environmental changes and climate stresses is important but largely unexplored. The workshop will highlight knowledge gaps and focus discussion on ways that ECEP can help to improve WEP system resilience.

Abstracts are invited for “Ignite” (5-minute) and longer (15-minute) presentations. Participants are welcome from all areas involved in strengthening societal resilience to weather and climate extremes.
 
Participants include representatives from Indigenous Americans, Re/insurance, Local Government, Industry and Business, and National and International Universities.

TUTORIAL OVERVIEW 

 The Weather Research and Forecasting (WRF) model Tutorial will be offered from 25 July- 3 August 2016 at the NCAR Foothills Laboratory, Boulder, Colorado.

The Basic tutorial will consist of lectures on various components of the WRF modeling system along with hands-on practice sessions. The topics include:

  1. WRF Pre-processing System
  2. WRF Dynamics and Numerics
  3. WRF Physics
  4. WRF Software Framework
  5. WRF Post-processing and Graphical Tools

The WRFDA tutorial will include lectures on a variety of topics on the full capability of the WRFDA system, along with hands-on practice sessions. The topics covered will include:

  1. Observation types, formats, and preprocessing
  2. Background error modeling and estimation
  3. 3D- and 4D-Variational data assimilation
  4. Ensemble and Hybrid Variational-Ensemble data assimilation methods
  5. Cycling with WRF and WRFDA
  6. Visualization and verification tools

REQUIREMENTS

Basic knowledge of atmospheric science and numerical modeling, as well as working in a Unix computer environment, is required for the class. WRF Tutorial participants are strongly encouraged to work through the WRF-ARW online tutorial, especially if you have not used the model before. Walking through the online tutorial will provide an overview of the system, which can help enhance your learning experience once you are here (even if you cannot compile and run the code physically). If you run into any problems while working through this, feel free to contact "wrfhelp at ucar dot edu".

All participants are also strongly encouraged to get familiar with Unix/Linux working environment, as working through directories, editing text files and Fortran code are absolutely essential to operate the modeling system programs. One can easily find Unix tutorials for beginners online for this purpose.
