We will provide a comprehensive overview of the development and significance of large-language models, highlighting the foundational aspects of the transformer architecture. This examination will elucidate the various applications of the transformer and distinctly showcase the decoder-only variant, which is a next-word predictor. The discussion will progress to practical tools to support the composition of papers written in Latex using Overleaf, a popular platform. We will then offer a comparative analysis of models such as ChatGPT, GPT4, Claude, and Perplexity.ai, detailing the optimal usage scenarios for each. A significant segment will be dedicated to AI's role in education. We will assess its utility for students and faculty in the classroom while addressing concerns about academic integrity and potential misuse. Further, we will delve into the practical applications of AI in coding, with a specific focus on Copilot's integration in Visual Studio Code and its implications for development efficiency. If time permits, we will list some creative applications of language models using tools such as Langchain. We will conclude with an outlook on the future implications of AI in the educational sector and its potential impact on student learning and interaction. -------------- next part -------------- An HTML attachment was scrubbed...

This week, we will have Dr. Ming Cai of FSU/EOAS as the speaker. The following is the information about his talk. Time: Friday, Sep 8 @ 3:00 PM Location: EOAS 1050 (regular EOAS colloquium room) Title: Difference between 1=1 and 3=3: Energy Gain Kernel for Climate Feedbacks Abstract: This study introduces a climate feedback kernel, referred to as the ?energy gain kernel? (EGK). The EGK allows for separating the net radiative energy perturbations given by a Planck feedback matrix explicitly into thermal energy emission perturbations of an individual layer, and thermal energy perturbations absorbed by all layers in response to forcing in that layer. The formal is represented by the diagonal matrix of a Planck feedback matrix and the latter by EGK. Elements of EGK are all positive, representing amplified energy perturbations at a layer where forcing is imposed and energy gained at other layers, both of which are achieved through radiative thermal coupling within an atmosphere-surface column. Applying EGK to input energy perturbations?whether external or internal due to responses of non-temperature feedback processes to external energy perturbations, such as water vapor and albedo feedbacks?yields their total energy perturbations amplified through radiative thermal coupling within an atmosphere-surface column. As the strength of EGK depends exclusively on climate mean state information, it offers a solution for effectively and objectively separating control climate state information from climate perturbations for climate feedback studies. Given that an EGK comprises critical climate mean state information on mean temperature, water vapor, clouds, and surface pressure, we envision that the diversity of EGK across different climate models could provide insight into the inquiry of why, under the same anthropogenic greenhouse gas increase scenario, different models yield varying degrees of global mean surface warming.

SEMINAR LOCATION: EOA 1044 (Speaker remote) SPEAKER: Dr. Katinka Bellomo TITLE: The influence of the AMOC decline on climate change impacts ABSTRACT: In climate model simulations of future climate change, the Atlantic Meridional Overturning Circulation (AMOC) is projected to decline. However, the impacts of this decline, relative to other changes, remain to be identified. In this talk, I will present some recent work in which we address this issue using climate models. First, I will present results of idealized model experiments with state-of-the-art model EC-Earth3. In these experiments, we artificially control the strength of the AMOC, which allows us to compare the impacts of an AMOC decline compared to a control climate. We find that an AMOC decline leads to mean climate changes, including global cooling, widespread drying in the Northern Hemisphere and a southward shift of the ITCZ. We also find an increased frequency of wintertime NAO+ and more extreme precipitation events in northwestern Europe, despite the overall drying. I will then compare these results with model projections of future climate change in the CMIP archives. In simulations of future climate change, there is large consensus among models that the AMOC declines in response to greenhouse gas forcing. However, there exists a large inter-model spread in the amount of the AMOC decline. To investigate the impacts of the inter-model uncertainty in the AMOC response, we group models based on how much the AMOC declines. We find that in models with larger AMOC decline, there is a minimum warming in the North Atlantic, a southward displacement of the Inter-tropical Convergence Zone, and a poleward shift of the mid-latitude jet. The changes in the models with smaller AMOC decline are drastically different: there is a relatively larger warming in the North Atlantic, the precipitation response exhibits a wet-get-wetter, dry-get- drier pattern, and there are smaller displacements of the mid-latitude jet. Models projecting a larger AMOC decline also show an increased frequency of wintertime NAO+ compared to models projecting a smaller AMOC decline. Our study indicates that the AMOC is a major source of inter-model uncertainty, which leads to large differences in simulated climate impacts in the near future. Finally, will discuss strategies to further assess the role of AMOC in the climate system, including in climate change projections, and also possible observational constraints that could help us reduced the uncertainty in the AMOC response in model projections of future climate change. We look forward to seeing you there! -------------------------------------------- Allison A. Wing, Ph.D. Werner A. and Shirley B.

Applications for 2025 will open late October/November 2023. David Zierden: Summer Heat Description: The meteorological summer of 2023 (June - August) brought exceptional and record-breaking heat. This applies to the global average temperature along with regional temperature patterns in Florida and along the Gulf Coast. The record-breaking warmth also includes many regions of the world's oceans, from the North Atlantic to the Mediterranean and parts of the Gulf of Mexico. Water temperatures around southwest Florida and the Florida Keys have been exceptionally warm, resulting in an ongoing coral bleaching event that is unprecedented. We will examine the severity, extent, and impacts of the record-breaking heat in this presentation. Alice Brennan: Trends of Southeast Asia Rainy Season Description: A study investigating the trends of the precipitation seasonality over the Southeast Asia (SEA) region. This project researched the 22 years (2001-2022) of the average onset and demise dates of the rainy season over the SEA region, along with the length of the season and the average amount of precipitation received. From the area average data, individual grid point data are then going to be plotted to visually interpret data for the entire region.

Raftery will present ?Downscaled Probabilistic Climate Change Projections, with Application to Hot Days,? on October 25, 2023 at 11:00am in the CSL auditorium at Florida State University. The live talk will also be accessible via Zoom. The registration link for the talk will soon be available at stat.fsu.edu/HollanderLecture. About Dr. Raftery Born in Dublin, Ireland, Adrian E. Raftery obtained a B.A. in Mathematics (1976) and an M.Sc. in Statistics and Operations Research (1977) at Trinity College Dublin. He obtained a doctorate in mathematical statistics in 1980 from the Universit? Pierre et Marie Curie in Paris, France. He was a lecturer in statistics at Trinity College Dublin from 1980 to 1986, and then joined the faculty in statistics and sociology at the University of Washington. He was the founding Director of the Center for Statistics and Social Sciences (1999-2009). His research focuses on Bayesian model selection and Bayesian model averaging, model-based clustering, inference for deterministic simulation models, and the development of new statistical methods for demography, sociology, and the environmental and health sciences. Raftery has published over 200 articles, edited three volumes of the annual Sociological Methodology compilation, co-edited Statistics in the 21st Century (2002), and co-authored the text Model-based Clustering and Classication for Data Science, with Applications in R (2019). He is an elected member of the U.S. National Academy of Sciences and of the Sociological Research Association, and Honorary Member of the Royal Irish Academy. He is a fellow of the American Statistical Association, the Institute of Mathematical Statistics and elected member of the International Statistical Institute. Lecture Abstract The climate change projections of the Intergovernmental Panel on Climate Change are based on scenarios for future emissions, but these are not statistically based and do not have a full probabilistic interpretation. Instead, Raftery et al. (2017) and Liu and Raftery (2021) developed probabilistic forecasts for global average temperature change to 2100. I will describe a method for downscaling these to yield probabilistic long-term spatial forecasts of local average annual temperature change, combining the probabilistic global method with a pattern scaling approach. This yields a probability distribution for average temperature in any year and any place in the future. Finally, we ask, how common dangerously hot days are likely to be at any location by the end of the century, and develop a method for assessing its predictive distribution. We find, for example, that exposure to dangerous heat levels is likely to increase by factors of 3-10 in many parts of the midlatitudes. -------------- next part -------------- An HTML attachment was scrubbed...

SEMINAR LOCATION: EOA 1044 (Speaker in person) SPEAKER: Prof. Hristo Chipilski TITLE: Data Assimilation Meets AI: New Horizons for Earth System Modeling ABSTRACT: Our understanding of the Earth system hinges on the effective use of observations and numerical models. However, each comes with its own set of limitations: observations provide an incomplete description of the physical state, while numerical models can deviate from reality due to their inherent simplifications. The field of data assimilation (DA) reconciles these problems by merging observations and models in a statistically optimal way. Despite their numerous advantages, traditional DA methods are derived from crude statistical assumptions which do not allow them to make full use of the available observations. In this seminar, I will elucidate these limitations through convective-scale simulations initialized with ground-based remote sensing retrievals. For a DA system based on the popular ensemble Kalman filter (EnKF), I will demonstrate that systematic improvements in the forecast skill occur only when assimilating measurements that capture both the thermodynamic and kinematic characteristics of the lower atmosphere. Motivated by this finding, I will then present a new ensemble-based DA framework which combines traditional estimation methods and emerging AI tools. The new theory leverages the special mathematical properties of invertible neural networks to generalize the EnKF algorithm to arbitrarily complex distributions. Idealized experiments reveal that the most substantial gains from the new DA framework occur when observation errors are small and model variables are strongly correlated. We look forward to seeing you there! ?????????????????? Allison Wing, Ph.D. Werner A. and Shirley B.

Subseafloor Hydrogeology: Moving Beyond Watersheds The field of submarine groundwater discharge (SGD) was launched in the 1990s by the remarkable discovery, via naturally occurring isotopic tracers, that saline groundwater was discharging to the South Atlantic Bight in very large volumes. Subsequent studies confirmed that saline groundwater discharges to the Atlantic Ocean in volumes that rival river discharge. All available evidence indicates that this saline groundwater is highly enriched in nutrients compared to river water, so the nutrient contributions of this submarine discharge exceed that of river discharge. These findings have been slow to find widespread acceptance, however, because it has been exceedingly difficult to confirm this flow by means other than the original isotropic tracers. This discharge does not occur near the shoreline, and no conceptual models for SGD far from shore existed. This changed recently when new studies using heat as a tracer identified clear pulses of groundwater discharge 10-15 km offshore in the South Atlantic Bight. This talk investigates this 20-year mystery and the recent discoveries that suggest that it may be time to rewrite chemical budgets for the coastal ocean.

SEMINAR LOCATION: EOA 1044 (Speaker in person) SPEAKER: Prof. Hristo Chipilski TITLE: Data Assimilation Meets AI: New Horizons for Earth System Modeling ABSTRACT: Our understanding of the Earth system hinges on the effective use of observations and numerical models. However, each comes with its own set of limitations: observations provide an incomplete description of the physical state, while numerical models can deviate from reality due to their inherent simplifications. The field of data assimilation (DA) reconciles these problems by merging observations and models in a statistically optimal way. Despite their numerous advantages, traditional DA methods are derived from crude statistical assumptions which do not allow them to make full use of the available observations. In this seminar, I will elucidate these limitations through convective-scale simulations initialized with ground-based remote sensing retrievals. For a DA system based on the popular ensemble Kalman filter (EnKF), I will demonstrate that systematic improvements in the forecast skill occur only when assimilating measurements that capture both the thermodynamic and kinematic characteristics of the lower atmosphere. Motivated by this finding, I will then present a new ensemble-based DA framework which combines traditional estimation methods and emerging AI tools. The new theory leverages the special mathematical properties of invertible neural networks to generalize the EnKF algorithm to arbitrarily complex distributions. Idealized experiments reveal that the most substantial gains from the new DA framework occur when observation errors are small and model variables are strongly correlated. We look forward to seeing you there! ?????????????????? Allison Wing, Ph.D. Werner A. and Shirley B.

Colloquium - 499 DSL Seminar Room Abstract: In this talk, we will discuss new finite element methods for solving three distinct problems: coupled flow and transport systems in porous media, linear elasticity (mechanics) equations, and the coupled mechanics and flow, known as poroelasticity. The primary goal of this study is to develop computationally efficient and robust numerical methods that are free from both oscillations due to the lack of local conservation and locking effects. The locally conservative enriched Galerkin (LF-EG) method, which will be used to solve the flow problem, is constructed by adding a constant function to each element based on classical continuous Galerkin methods. The locking-free enriched Galerkin (LC-EG) method adds a vector to the displacement space. These EG methods employ well-known discontinuous Galerkin (DG) techniques, but the approximation spaces have fewer degrees of freedom compared to typical DG methods, thus offering an efficient alternative to DG methods. We will present a priori error estimates of optimal order and demonstrate, through numerical examples, that the new method is free from oscillations and locking.

SEMINAR LOCATION: EOA 1044 (Speaker remote) SPEAKER: Dr. Arianna Varuolo-Clarke TITLE: The mystery of observed and simulated precipitation trends in Southeastern South America since the early 20th century ABSTRACT: Southeastern South America (SESA), a region encompassing Paraguay, Southern Brazil, Uruguay, and northern Argentina, experienced a 23% increase in austral summer precipitation from 1902-2022, one of the largest observed precipitation trends globally. There is little consensus on the drivers of the precipitation trend, but Atlantic multidecadal variability, stratospheric ozone depletion, and greenhouse gas emissions stand out as key contributing factors. In this presentation, I will walk through my process of trying to understand first, what are the historical drivers of the SESA precipitation increase. And second, why do climate models struggle to simulate the observed SESA precipitation trend? To address the first question, I explore simulations from the Coupled Model Intercomparison Project (CMIP) Phases 3, 5, and 6 and find that not only do fully-coupled climate models simulate positive SESA precipitation trends that are much weaker over the historical interval, but some models persistently simulate negative precipitation trends. In an attempt to understand this apparent model bias, and why climate models seem to miss the trend, I investigate one driver of SESA precipitation variability: the South American low-level jet. I find that the SESA precipitation trend from 1951-2020 is partly attributable to jet intensification arising from both natural variability and anthropogenic forcing. -------------------------------------------- Allison A.

The wavelet approach to wavenumber spectral analyses on inhomogeneous and non-periodic flows By Takaya Uchida Description: While Fourier methods have provided us with immense benefits in extracting the spatiotemporal scales of turbulent flows, they come with its shortcomings of requiring the data to be periodic and homogenous. Such requirements skew the data and introduce artifacts stemming from the windowing/tapering applied to make the data periodic. Here, a wavelet-based method is re-introduced in an oceanographic and spectral context to estimate localized wavenumber spectrum and spectral flux of kinetic energy and enstrophy. We apply this to a numerical simulation of idealized, doubly-periodic quasi-geostrophic flows, i.e. the flow is constrained by the Coriolis force and vertical stratification. The double periodicity allows for a straightforward Fourier analysis as the baseline method. Our wavelet spectra agree well with the canonical Fourier approach but with the additional strengths of negating the necessity for the data to be periodic and being able to extract local anisotropies in the flow. Caution is warranted, however, when computing higher-order quantities, such as spectral flux. Ocean sound speed profile clustering in the Gulf Stream separation region By Ethan Wright Description: Vertical profiles of sound speed in the ocean are critical to sonar applications, such as automated target localization and optimal navigation routing for underwater vehicles. For these applications, vertical profiles of sound speed are used to estimate transmission loss. Calculating representative sound speed profiles in areas where contrasting water masses are present is a challenging task. In these areas, averaging a set of sound speed profiles over time can lead to an erroneous profile that is not associated with a particular water mass. One such region with strongly fluctuating sound speed conditions is the separation region of the Gulf Stream from the North American continent. The goal of this study is to analyze the different techniques for clustering that lead to the best representation of the range of conditions most important to sound transmission in this region. To capture the variability of the dominant sound speed conditions, a machine learning approach is introduced where vertical sound speed profiles calculated from ARGO float data are clustered using k-means and hierarchical agglomerative clustering.
