High Resolution Sea Surface Height with Machine Learning By Jorge Velasco Description: TBD Breaking Down the Effects of Current Feedback Coupling Onto the Atmosphere By Kamran Chowdhury Description: The ocean and atmosphere interact through two major mechanisms: thermal feedback (TFB) and current feedback (CFB). The impacts of CFB onto the atmospheric boundary layer are often underestimated in modeling for research and forecasting. My work aims to expound upon some of the dynamical effects of CFB on the atmosphere, see how CFB modifies the atmospheric response from TFB, and attempt to capture non-local responses arising from CFB.

Location: EOA 1044 Speaker: Dr. Zhaohua Wu, EOAS, Florida State University Title: Reconciliation of Conservation Laws for Waves in a Spatially Varying and Inhomogeneously Moving Medium Abstract: Waves are propagating disturbances that redistribute energy across space. Their propagation involves the exchange of energy between the waves and the surrounding medium. This energy exchange can serve two primary roles: (1) facilitating the propagation of the wave, and (2) acting as an energy source or sink for the wave, potentially leading to instabilities. The tendency of the medium to return to its original state after the wave passes suggests that its principal function is to enable wave propagation?implying that wave energy conservation should hold, even in the presence of local energy exchange with the medium. However, previous studies have shown that in inhomogeneously moving mean flows?a specific class of varying media?the conserved quantity is wave action rather than wave energy. This apparent contradiction has remained unresolved. In this study, we address and resolve this sixty-year dilemma. By approximating a continuously varying medium as a series of infinitesimally small, piecewise constant segments and accounting for energy reflection at their interfaces, we demonstrate that wave action conservation is, in fact, an emergent form of wave energy conservation in spatially varying and inhomogeneously moving media, where waves deform as they propagate. Furthermore, we show that wave action conservation can be derived directly from the fundamental law of energy conservation. This result applies universally to all isolated wave systems in varying media, encompassing both hydrodynamic and non-hydrodynamic waves. =============== Cheers, Ming Ye and Zhaohua Wu -------------- next part -------------- An HTML attachment was scrubbed...

Colloquium - 499 DSL Seminar Room Abstract: Air pollution surveillance is critically important for public health. To monitor a sequential process online, a major statistical tool is statistical process control (SPC) chart. However, traditional SPC charts are developed mainly for monitoring production lines in the manufacturing industry under the assumptions that process observations at different observation times are independent and identically distributed with a parametric (e.g., normal) distribution when the process is stable. Nevertheless, the air pollution and meteorological data would not satisfy these conditions due to serial correlation, seasonality, and other complex data structure. In this talk, we present our latest research on sequential monitoring of air quality over time. In particular, we propose a flexible method for sequential monitoring of high-dimensional dynamic processes with serially correlated data. The new method is based on nonparametric longitudinal modeling for describing the longitudinal pattern of the process under monitoring, principal component analysis for dimension reduction, and a sequential learning algorithm for developing an effective decision rule. Numerical studies and real data applications show that the proposed method works well.

Nespresso & Teatime - 417 DSL Commons * 3:30 to 4:30 PM Eastern Time (US and Canada) ? Colloquium - 499 DSL Seminar Room Abstract: Operator learning arises widely in scientific computing, especially for partial differential equations (PDEs) where operators map between Banach or Hilbert spaces. We study the more general setting of Banach-valued operators, focusing on holomorphic mappings with broad applications. Two complementary approaches are considered: compressed sensing (CS) for sparse polynomial approximation and deep neural networks (DNNs) with arbitrary encoders/decoders and standard feedforward architectures. CS exploits sparsity to achieve accurate approximations with minimal samples, while our DNN analysis identifies architectures with optimal generalization bounds independent of operator regularity, with width and depth depending only on the number of training samples. We show that deep learning is minimax-optimal for this problem, i.e., no recovery method can surpass its generalization bounds up to logarithmic terms, and that fully connected networks admit uncountably many optimal minimizers. A full error analysis accounting for approximation, discretization, and optimization is provided, along with numerical experiments on challenging PDE models including parametric diffusion with and without advection and reaction terms, Navier-Stokes-Brinkman, and Boussinesq equations. Finally, we extend CS techniques for sparse orthonormal polynomial approximation to Banach-valued settings, using a GPU-accelerated restarted primal-dual algorithm for ?1-minimization, enabling direct comparison of the two approaches and highlighting their respective strengths.

Location: EOA 1044 Speaker: Prof. Christopher Holmes, EOAS, Florida State University Title: Where there?s fire, there?s smoke: fires and air quality in the eastern United States Abstract: Fires are widespread and frequent across the eastern United States, as they are used extensively for wildfire mitigation, ecosystem management, and disposing of biomass debris from agriculture and land clearing. Historically, the extent of these fires has been underestimated due to the lack of comprehensive burn records and the difficulty of detecting small, short-duration fires from satellites. Our analysis of fire records finds that prescribed fire policy in Florida is successfully interrupting the natural moisture controls on fire, reducing wildfire risks for the state. We use improved fire detections from geostationary satellite instruments (Advanced Baseline Imager (ABI) on GOES) and a new compilation of locally specific emission factors to develop a new biomass burning inventory for the eastern U.S. We use this emission inventory in an atmospheric chemistry model to simulate air quality across the U.S. and evaluate the model with aerosol measurements from the surface, satellites, and aircraft. The new inventory fits these observations better than multiple other emission inventories and suggests that fire emissions are higher than most previous estimates with air quality impacts 2-4 times larger than previous assessments. We discuss the implications for health and prescribed fire management. =============== Cheers, Ming Ye and Zhaohua Wu -------------- next part -------------- An HTML attachment was scrubbed...

DATE: Tuesday September 23 TIME: 3-4 PM, please join early for refreshments LOCATION: EOA 1044 (speaker in person) SPEAKER: Dr. Chris Landsea TITLE: Opportunities of Applied Hurricane Research in the Midst of Hurricane Forecasting Operations ABSTRACT: In my meteorological career, I've been quite fortunate to have worked at a few amazing offices including the Aircraft Operations Center, the Bureau of Meteorology Research Centre, the Hurricane Research Division, and - since 2005 - the National Hurricane Center as the Science and Operations Officer and the Tropical Analysis and Forecast Branch Chief. But despite the last two decades working in forecast operations, I still consider myself foremost a researcher. During our tropical and marine operations, questions have often come up that we didn't readily have answers to. Questions like: what are the constraints for how fast tropical cyclones can intensify? do small tropical cyclones spin up faster than larger ones? do we have any skill in forecasting the size of tropical cyclones? and what are the limits for predicting the track and intensity of tropical cyclones? This mini-potpourri of topics will be discussed to provide the answers that we arrived at as we conduct science operationally on a daily basis at the National Hurricane Center.

Colloquium - 499 DSL Seminar Room Abstract: Agriculture is a cornerstone of Florida?s economy, particularly in South Florida. However, intensive farming practices are closely tied to heavy pesticide use, raising concerns about water quality. Chlorothalonil, a broad-spectrum fungicide widely applied in the region, has an uncertain environmental fate and transport behavior. In particular, the key processes and parameters governing its movement and transformation in natural systems remain poorly understood. In this study, we applied the U.S. EPA?s Pesticide in Water Calculator (PWC) to simulate the transport of chlorothalonil and its major transformation product from land surface to shallow groundwater and adjacent drainage ditch. The model accounts for precipitation?runoff, erosion, crop growth, evapotranspiration, soil water movement, and pesticide degradation in soil, surface water and sediment. We calibrated the hydrological module against field data collected in South Florida during spring 2025, achieving satisfactory model performance. Scenario analyses of pesticide applications were then conducted to evaluate pesticide fate under different management conditions. To further address the complexity of reactive transport in natural systems, we are developing a Bayesian network?based global sensitivity framework. Overall, this research provides quantitative insights into contamination risks to local water resources and advances our understanding of the environmental drivers and transport mechanisms in this vulnerable agricultural region.

But despite the last two decades working in forecast operations, I still consider myself foremost a researcher. During our tropical and marine operations, questions have often come up that we didn't readily have answers to. Questions like: what are the constraints for how fast tropical cyclones can intensify? do small tropical cyclones spin up faster than larger ones? do we have any skill in forecasting the size of tropical cyclones? and what are the limits for predicting the track and intensity of tropical cyclones? This mini-potpourri of topics will be discussed to provide the answers that we arrived at as we conduct science operationally on a daily basis at the National Hurricane Center. We look forward to seeing you there! Cheers, Allison --------------------------------------------------- Allison A. Wing, Ph.D. Werner A. and Shirley B.

Leung TITLE: Seeing the forest for the trees: How spatial patterns in land?aerosol?atmosphere interactions shape cloud responses ABSTRACT: Human activities impact clouds in many ways, notably through changes in land surface properties and aerosol emissions. Improving our understanding of land?aerosol?atmosphere interactions is essential for accurately assessing how clouds may change in the future. This talk will focus on how the mesoscale (O(100km)) pattern of aerosol and surface perturbations?though often unresolved in large-scale models?can shape overall responses in clouds and rainfall. First, I will demonstrate how spatial gradients in aerosol emissions, such as those around wildfires or urban areas, drive aerosol breeze circulations. These localized circulations can substantially alter the magnitude and spatial distribution of clouds and rain. Second, I will use high-resolution simulations and object-tracking methods to explore cloud responses to realistic patterns of tropical deforestation. Localized deforestation-driven changes to boundary layer processes drive mesoscale flow adjustments, resulting in widespread reductions in shallow cloud cover, but increases in cloudiness along the boundary between forested and deforested areas. Finally, I will present long-term satellite estimates of cloud responses to deforestation. Although deforestation impacts on cloudiness are robust, the magnitude of the cloud response is not uniform everywhere. Due to the background moisture and aerosol environment, some areas are especially susceptible to deforestation-induced changes in cloud properties. Understanding land?aerosol?atmosphere interactions in the context of their spatial patterns leads to a fuller picture not only of how land and aerosol perturbations impact clouds, but also where and when such perturbations might be most important for weather and climate.
