The simulation covers the historical period (1985?2014) and a future projection (2071?2100) under the SSP5-8.5 scenario. Evaluation of present-day simulation against observations shows that the RSM-ROMS captures key mesoscale features and improves the summer rainfall seasonal cycle compared to CESM2, though a dry bias persists over adjacent oceans. Building on prior successful validation with CMIP5's CCSM4, this RCM provides the first high-resolution, CMIP6-forced regional coupled simulation for Florida. In addition, the analysis shows that the RSM?ROMS simulations are consistent with ensembles of 23 CMIP6 global models and their statistically downscaled NEX-GDDP counterparts. Together, these analyses highlight the added value of high-resolution coupled downscaling for assessing projected changes in extreme rainfall events over Florida. We look forward to seeing you there!

They capture ocean motions across a wide range of spatial and temporal following the trajectories. However, the statistics derived from these observations are fundamentally nonlocal, as they involve averaging along trajectories. In contrast, much of our understanding of the ocean is formulated in a Eulerian (local) framework, where properties are defined at fixed locations?consistent with how ocean models represent processes. An example is mesoscale eddy diffusivity, which quantifies the strength of eddy-driven mixing and is defined locally due to the spatial inhomogeneity of eddies. Traditional estimates using Lagrangian trajectories rely on long-time averages, yielding asymptotic eddy diffusivity that obscure the spatiotemporal variability. This highlights the need for methods that connect nonlocal Lagrangian measurements with local Eulerian statistics. In this talk, I will present a ?hybrid? approach for inferring Eulerian fields directly from Lagrangian trajectories. The central idea is that continuous evolution of fluids can be reconstructed from motions of a finite set of fluid parcels. Using an idealized eddy-resolving model, we reconstructed Eulerian fields?including tracer concentration, eddy tracer fluxes, and eddy diffusivity from Lagrangian particles alone. The fields closely match their purely Eulerian counterparts. Finally, I will discuss potential extensions of this idea to broader oceanographic contexts. The goal is to explore new ways of using Lagrangian measurements to advance our understanding of ocean processes and generate projects to collaborate with COAPS colleagues.

Location: EOA 1044 Speaker: Harley Means, Director, Florida Geological Survey Title: The Florida Geological Survey - Who We Are, What We Do and Collaborative Opportunities Abstract: The Florida Geological Survey (FGS) was established by the Florida Legislature in 1907 and is one of the longest, continuously functioning state organizations. The mission of the FGS is to: collect, interpret, maintain, and distribute geologic information to benefit Florida. The FGS is currently located at 3000 Commonwealth Boulevard in Tallahassee, however, we were located on the Florida State University (FSU) campus adjacent to the Geology Department for nearly 58 years. In August of 2014, the FGS moved out of the Herman Gunter Building, and it was demolished to make room for the Earth, Ocean and Atmospheric Sciences Building. FSU and the FGS have historically collaborated on geologic research projects and the FGS has employed many FSU graduates over the years. The last four Florida State Geologists held degrees in geology from FSU and many of our current research geologists have degrees from FSU. In this presentation I will provide a historic overview of the FGS, discuss some ongoing projects and propose some ideas for future FGS/FSU collaboration. =============== Cheers, Ming Ye, Robert Spencer, and Zhaohua Wu *************************************************************** Zhaohua Wu, Professor Earth, Ocean, and Atmospheric Science Building, Room 6041, and Center for Ocean-Atmospheric Prediction Studies, Room 295 Florida State University Tallahassee, Florida zwu at fsu.edu **************************************************************** -------------- next part -------------- An HTML attachment was scrubbed...

Colloquium - 499 DSL Seminar Room Abstract: As artificial intelligence becomes increasingly integrated into all facets of education, faculty across the disciplines are grappling with questions about how AI tools impact student learning and development. This presentation, from the perspective of a faculty member in the humanities, addresses anxieties that have driven initial resistance to AI adoption on my side of campus, but I want to emphasize the pedagogical opportunities and collaborations that I see emerging when we focus on critical AI literacies within our pedagogies. Concerns about AI from the humanities tend to reflect fears about AI undermining learning and cognitive development, de-humanizing creative practices, and weakening intellectual agency. Recent studies suggest that students may experience reduced cognitive engagement when composing with AI assistance, raising questions about how to scaffold engaged learning experiences into our work with AI. As such, I argue that regardless of discipline, we should all be working together toward helping students develop critical AI literacies so that they can engage productively and reflectively with these new technologies. Moving beyond simplistic frameworks that equate AI use with academic dishonesty, I?ll present an approach that distinguishes between AI uses that enhance and those that undermine teaching and learning. The focus of this presentation will be designing intellectually rich, pedagogically sound AI strategies that support rather than replace critical thinking, human experience, ethical decision-making, and creative expression. Such an approach demands moving from blanket institutional policies toward discipline-, course-, and assignment-specific guidelines that explicitly connect AI use to learning outcomes. This talk aims to foster dialogue between the humanities and computing with the belief that effective AI integration into educational settings requires both technical expertise and humanistic insights into embodied human learning.

Location: EOA 1044 Speaker: Dr. Marco Larra?aga, Center for Ocean-Atmospheric Prediction Studies, Florida Geological Survey Title: The Florida Geological Survey - Who We Are, What We Do and Collaborative Opportunities Abstract: Mesoscale eddies significantly influence ocean-atmosphere interactions through both direct and indirect feedback mechanisms. Thermal feedback refers to how mesoscale eddies induce spatial anomalies in sea surface temperature, modulating the exchange of heat and momentum between the ocean and the atmosphere and driving local weather variability. In addition to thermal feedback, current feedback plays a crucial role in the energy dynamics of the ocean. This mechanism acts as an energy sink, transferring kinetic energy from the ocean's mesoscale features to the atmosphere, thus reducing eddy kinetic energy by approximately 30% in regions characterized by high mesoscale activity. In the Gulf of Mexico, a region with intense mesoscale dynamics influenced by the Loop Current and the eddies that the current detaches, the current feedback mechanism dampens mesoscale activity by roughly 20%. This energy reduction modifies the detachment statistics of Loop Current eddies, influencing their shedding frequency, size, and lifespan. Such alterations in eddy properties have broader implications for regional oceanic and atmospheric dynamics. Furthermore, mesoscale eddies indirectly impact the generation of sea surface waves. By inducing anomalies in the wind stress field, the current feedback leads to a tendency for increased wave heights. These findings underscore the importance of considering current feedback mechanisms in coupled ocean-sea surface waves-atmosphere simulations to enhance predictions of oceanic and atmospheric variability ==============+ Cheers, Ming Ye, Robert Spencer, and Zhaohua Wu *************************************************************** Zhaohua Wu, Professor Earth, Ocean, and Atmospheric Science Building, Room 6041, and Center for Ocean-Atmospheric Prediction Studies, Room 295 Florida State University Tallahassee, Florida zwu at fsu.edu **************************************************************** -------------- next part -------------- An HTML attachment was scrubbed...

The lecture will be given by Professor Adam Sobel from Columbia University who will speak about Tropical Cyclone Risk and the State of the Tropical Pacific. Please see below and the attached flyer for more information. We look forward to having a great turnout for what promises to be a fascinating lecture on a very timely topic. Prof. Sobel will be visiting EOAS from Thursday November 13- Friday November 14 and there will be opportunities for faculty, researchers, and students to meet with him. I will be arranging his schedule of meetings as we get closer to the date. Please feel free to forward to this announcement to other colleagues of yours who might be interested in attending the lecture. Speaker: Professor Adam Sobel Date & Time: Friday November 14, 3 PM Location: EOA 1050 Title: Tropical cyclone risk and the state of the tropical Pacific Abstract: Tropical cyclone (TC) risk is strongly modulated by the state of the tropical Pacific climate. During El Ni?o events, for example, TC activity is suppressed in the North Atlantic (thus TC risk to the U.S. is generally reduced) and enhanced in the northeast Pacific, while the opposite occurs during La Ni?a events. Virtually all Earth system models simulate long-term trends in sea surface temperature under greenhouse gas warming that are structurally similar to El Ni?o, with greater warming in the eastern and central equatorial Pacific than in the rest of the basin. Unsurprisingly, predictions and projections of TC activity based on these models (for example, using statistical-dynamical downscaling models which take the simulated climates from Earth system models as input) generate results that are also broadly similar to what happens in El Ni?o events, including suppressed Atlantic activity. Yet over the last several decades, observations have shown trends that are more similar to La Ni?a, approximately opposite to what the models say should have happened. It now seems likely that this is not just a result of internal variability, but that the models are in fact wrong in their representations of the tropical Pacific?s response to radiative forcing. How then should we generate estimates of TC activity for the present and near future? I will present results from a couple of ongoing projects in which we try to 1) understand why the models might be wrong about tropical Pacific trends, and 2) generate ?storylines? of near-term climate change, TC activity, and TC hazard and risk that are more consistent with recent history. --------------------------------------------------- Allison A.

Location: EOA 1044 Speaker: Dr. Marco Larra?aga, Center for Ocean-Atmospheric Prediction Studies, Florida State University Title: Exploring feedback mechanisms between the ocean, atmosphere, and sea surface waves at the mesoscale. Abstract: Mesoscale eddies significantly influence ocean-atmosphere interactions through both direct and indirect feedback mechanisms. Thermal feedback refers to how mesoscale eddies induce spatial anomalies in sea surface temperature, modulating the exchange of heat and momentum between the ocean and the atmosphere and driving local weather variability. In addition to thermal feedback, current feedback plays a crucial role in the energy dynamics of the ocean. This mechanism acts as an energy sink, transferring kinetic energy from the ocean's mesoscale features to the atmosphere, thus reducing eddy kinetic energy by approximately 30% in regions characterized by high mesoscale activity. In the Gulf of Mexico, a region with intense mesoscale dynamics influenced by the Loop Current and the eddies that the current detaches, the current feedback mechanism dampens mesoscale activity by roughly 20%. This energy reduction modifies the detachment statistics of Loop Current eddies, influencing their shedding frequency, size, and lifespan. Such alterations in eddy properties have broader implications for regional oceanic and atmospheric dynamics. Furthermore, mesoscale eddies indirectly impact the generation of sea surface waves. By inducing anomalies in the wind stress field, the current feedback leads to a tendency for increased wave heights. These findings underscore the importance of considering current feedback mechanisms in coupled ocean-sea surface waves-atmosphere simulations to enhance predictions of oceanic and atmospheric variability ==============+ Cheers, Ming Ye, Robert Spencer, and Zhaohua Wu *************************************************************** Zhaohua Wu, Professor Earth, Ocean, and Atmospheric Science Building, Room 6041, and Center for Ocean-Atmospheric Prediction Studies, Room 295 Florida State University Tallahassee, Florida zwu at fsu.edu **************************************************************** -------------- next part -------------- An HTML attachment was scrubbed...

DATE: Tuesday October 4 TIME: 3-4 PM, please join early for refreshments LOCATION: EOA 1044 (speaker in person) SPEAKER: Prof. Lee Murray TITLE: Atmosphere Chemistry Across Scales: From Drivers of Oxidative Capacity to Climate-Health Impacts ABSTRACT: The chemical composition of the atmosphere reflects a dynamic interplay of emissions, meteorology, and reactive chemistry. Oxidants such as hydroxyl radicals and ozone regulate the lifetimes of reactive greenhouse gases and air pollutants, shaping climate feedbacks as well as human, crop, and ecosystem exposure. Yet large uncertainties remain in how the atmosphere?s oxidative capacity responds to evolving emissions and climate change across past, present, and future time scales. This seminar examines how chemical and meteorological processes jointly control the global distribution of oxidants and their variability through space and time. Particular attention is given to lightning as a key coupling between atmospheric dynamics and chemistry, influencing the formation and transport of reactive nitrogen and radicals, and itself influenced by atmospheric composition. The discussion highlights how perturbations in chemistry and meteorology cascade through the Earth system to affect surface air quality, agricultural yields, and human health.

Location: EOA 1044 Speaker: Dr. Luolin Sun, Center for Ocean-Atmospheric Prediction Studies, Florida State University Title: Changes in ocean heat transport from the subpolar North Atlantic to the Arctic during recent decades Abstract: The Arctic Ocean has been warming nearly four times as fast as the global average since the 1990s, severely transforming the Arctic marine environment, yet the oceanic mechanisms underlying this rapid change are still not fully understood. In this study, I use a global ~1/12? ocean?sea-ice coupled HYCOM historical simulation during 1980?2023 to represent the volume transport from major oceanic gateways into the Arctic. The model results show good agreement with observations in the strength of the Atlantic Meridional Overturning Circulation (AMOC) at OSNAP array during the observational period. In this talk, I will discuss the Arctic heat budget and focus on the poleward ocean heat transport. I will show that the latter has multi-decadal variability and is mainly dominated by the meridional heat transport through the Barents Sea Opening and Fram Strait. I will further show how the changes in the heat transport from the subpolar North Atlantic are attributed to the large-scale climate modes, such as the North Atlantic Oscillation (NAO). Finally, I will discuss ongoing work on the role of the AMOC in modulating poleward heat transport under a warming Arctic, offering new insights into how large-scale ocean circulation may influence the future Arctic climate. ==============+ Cheers, Ming Ye, Robert Spencer, and Zhaohua Wu *************************************************************** Zhaohua Wu, Professor Earth, Ocean, and Atmospheric Science Building, Room 6041, and Center for Ocean-Atmospheric Prediction Studies, Room 295 Florida State University Tallahassee, Florida zwu at fsu.edu **************************************************************** -------------- next part -------------- An HTML attachment was scrubbed...

This variability is particularly evident in TC genesis (TCG), an area with limited understanding due to sparse observations and uncertain model simulations. A primary issue associated with moderate VWS is the vortex tilt, displacement of low-level and mid-level vortex centers, leading to asymmetric TC structures. This study investigates the impact of vertical vortex structure on TC genesis under moderate VWS using numerical simulations with the Weather Research and Forecasting Model (WRF). There is variability in vertical profiles of pre-genesis vortices that serve as seeds for TCG. African Easterly Waves (AEWs) typically exhibit maximum vorticity near the mid-levels ($\sim$600 hPa), whereas Western Pacific Easterly Waves are characterized by low-level ($\sim$850 hPa) vortices. Our experimental design compares these two structures by centering the pre-genesis vortex at 600 hPa and 850 hPa, called Mid-Initiated and low-Initiated simulations respectively. We analyze variations in the timing of the genesis under moderate VWS and reduced moisture content. Mid-Initiated vortices tend to experience delayed genesis, often undergoing vortex reformation beforehand. In contrast, the timing of genesis in Low-Initiated vortices depends on the number of repeated, aligned precursor events; multiple failed attempts typically slow the onset of genesis. Key differences between Low-Initiated and Mid-Initiated ensembles include: (1) the Mid-Initiated members shows greater downshear left convection prior to genesis; (2) the Mid-Initiated members exhibits more evident vortex size expansion prior to genesis; (3) Mid-Initiated members display greater tilt at genesis, often necessitating a larger circulation and vortex reformation for successful development; (4) in Mid-Initiated runs, surface latent heat fluxes are more strongly aligned with the reformed vortex; and (5) they maintain higher stratiform coverage and deep-layer saturation fraction prior to genesis. These results together elucidate that Mid-Initiated vortices go through a different pathway with a greater role of mid-level vortex and low-level vortex reformation that was not apparent in Low-Initiated vortices in marginally favorable environments. The distinctive TCG pathways depending on initial vertical vortex profiles identified in this study will help enhance our TCG forecast accuracy in the low predictability regimes of moderate VWS. --------------- Chaehyeon Chelsea Nam, Ph.D. Assistant Professor Department of Earth, Ocean, and Atmospheric Science (EOAS) Florida State University RM 5011, ccnam at fsu.edu https://chelsea-nam.github.io/ -------------- next part -------------- An HTML attachment was scrubbed...

Colloquium - 499 DSL Seminar Room Abstract: The evolution of subsonic burning fronts, known as deflagrations or simply flames, is driven on scales comparable to the reaction zone's thickness. In an idealized one-dimensional scenario, the flame structure can be found by solving a set of ordinary differential equations that represent the interplay between hydrodynamics and combustion physics. In realistic multidimensional situations, the flame propagates into a perturbed fuel, which can geometrically deform the flame front and affect its internal structure. The effects of flame stretch and strain have been extensively studied by the combustion community since G. H. Markstein's pioneering work some 60 years ago. These efforts led to the Matalon?Matkowsky?Clavin?Joulin theory of strongly wrinkled premixed flames. However, the Matalon et al. theory only provides a local prescription of flame evolution and does not account for potential effects due to flame-fuel interactions, which modify the flow in regions significantly larger than the flame thickness. This problem is further complicated in computer models, which necessarily must employ formulations consistent with problem physics and typically use the Eulerian view of the fluid system. In such models, transport of fluid parcels across the Eulerian mesh destroys the history of individual fuel parcels and complicates analysis the analysis of flame-fuel interactions. This talk presents a Lagrangian analysis of flame-fuel interaction, which, for the first time, allows us to identify the physics responsible for the recently reported reduction in burning times as the distance to the flame front decreases.

DATE: Tuesday October 21 TIME: 3-4 PM, please join early for refreshments LOCATION: EOA 1044 (speaker remote) SPEAKER: Dr. Katrine Gorham TITLE: Atmospheric methane: exploring pathways to reduce climate risk ABSTRACT: Methane is the second-most important greenhouse gas and has contributed roughly 0.5 ?C to global warming relative to pre-industrial times. Natural sources are currently responsible for about 40% of methane emissions, and are expected to rise as temperatures warm, particularly from wetlands, freshwater systems, and thawing permafrost. While technologies for destroying methane emissions from higher concentration sources are being developed, there are no existing technologies for mitigating atmospheric methane at background atmospheric concentrations (2 ppm). The topic of atmospheric methane removal was the focus of a 2024 National Academies consensus study and is receiving increased attention from the academic research community. This presentation will explore the role that methane plays as a contributor to rising temperatures and consider hypothesized atmospheric methane removal approaches as part of a climate response portfolio.
