The influence of vertical resolution on internal tide energetics and its effects on underwater acoustics propagation By Luna Hiron Description: Internal tide generation and breaking play a primary role in the vertical transport and mixing of heat and other properties in the ocean interior, thereby influencing climate regulation. Additionally, internal tides increase sound speed variability in the ocean, consequently impacting underwater acoustic propagation. With advancements in large-scale ocean modeling capabilities, it is essential to assess the impact of higher model resolutions (horizontal and vertical) in representing internal tides. This study investigates the influence of vertical resolution on internal tide energetics and its subsequent effects on underwater acoustic propagation in the HYbrid Coordinate Ocean Model (HYCOM). An idealized configuration only forced with semidiurnal tides with 1 km horizontal grid-spacing and a ridge is used to test two different vertical-grid discretization and seven distinct numbers of layers, ranging from 8 to 128 isopycnal layers. Isopycnal layers are either defined by the zero-crossings of the horizontal velocity eigenfunctions or starting by the zero-crossings of the 128th mode horizontal velocity eigenfunction and removing intermediate layers. The analyses reveal that increasing the number of layers up to 48 layers increased the domain-integrated barotropic-to-baroclinic tidal conversion, available potential energy, and vertical kinetic energy, maintaining consistency in simulations with higher layer counts. Vertical shear exhibits a similar pattern but peaking at 96 layers. Simulations with at least 48 layers better resolved the available potential energy contained in modes higher than the 3rd baroclinic mode. Finally, acoustic analyses show an increase in sound speed variability, and subsequent changes in underwater acoustic propagation, with the addition of layers until 48 layers. Therefore, the study concludes that a minimum vertical resolution (48 layers in this case) is required to minimize the impact on internal tide properties and associated underwater acoustic propagation. The 2023/2024 El Ni?o - Evolution and Impacts By David Zierden Description: The current El Ni?o has been described as ?historically strong? by NOAA with Nino 3.4 values approaching +2.0 C above normal. The evolution of this event was out of the normal, with the greatest SST departures beginning in the eastern Pacific and spreading westward. Impacts from this El Ni?o event include Atlantic hurricane activity, frequent winter rain and storminess, and the threat of severe weather and coastal flooding. Introduction to Graphcast By Olmo Zavala Description: The GraphCast model is a machine learning-based method designed for global medium-range weather forecasting. It was trained directly from reanalysis data and is capable of predicting hundreds of weather variables over 10 days at a 0.25-degree resolution globally in under one minute. The model outperforms traditional numerical weather prediction systems and supports better severe event prediction, including tropical cyclones, atmospheric rivers, and extreme temperatures. It is a significant advancement in accurate and efficient weather forecasting. In this talk, I'll introduce its training process, the variables it predicts, its performance compared to traditional systems, and its impact on severe weather event prediction.

Satoru will be joining us in person here in EOAS and is available to meet throughout Wednesday and most of Thursday - please contact me if you would like to meet with him. DATE: Wednesday February 14 SEMINAR TIME: Talk 12 PM - 1 PM. SEMINAR LOCATION: EOA 3067 (Speaker in person) SPEAKER: Dr. Satoru Okajima TITLE: Transient eddy activity in midlatitudes: seasonality and air-sea interactions ABSTRACT: Transient eddies (migratory cyclones and anticyclones) are pivotal in both weather and climate in the extratropics. They account for most of the day-to-day weather variability and maintain background fields through their interaction with longer-scale atmospheric circulation variations and jet streams. Areas of vigorous transient eddy activity, called "storm tracks", are located over the North Pacific, North Atlantic, South Indian Ocean, and Mediterranean Sea. They are collocated well with regions of large lower-tropospheric baroclinicity. However, the seasonality of transient eddy activity and that of baroclinicity do not always correspond well with each other. In this talk, we will explore the results of studies on the distinctive seasonality of the transient eddy activity of oceanic storm tracks by comparing methods based on tracking individual cyclones/anticyclones and those based on temporally filtered local eddy statistics. Additionally, we will explore the role of atmospheric transient eddies in the midlatitude air-sea interactions. By quantifying the contributions of cyclones and anticyclones to climatological-mean heat and moisture supply from the ocean and rainfall along the two major oceanic frontal zones over the North Pacific and North Atlantic, we demonstrate that oceanic frontal zones climatologically act to strengthen the hydrological cycle between cyclones and anticyclones. ------------------------------------------------ Rhys Parfitt Assistant Professor, EOAS -------------- next part -------------- An HTML attachment was scrubbed...

Evidence from Recent Airborne Observations ABSTRACT: The recently-completed deployments of the Dynamics and Chemistry of the Summer Stratosphere (DCOTSS) field campaign during the summers of 2021 and 2022 resulted in extensive sampling of stratosphere air impacted by tropopause-overshooting convection (thunderstorms). DCOTSS was based out of Salina, Kansas in the central United States, near the climatological maximum in overshooting. Unprecedented evidence of extreme stratospheric hydration by convection was observed and reached altitudes up to 4 km above the tropopause and potential temperatures in excess of 450 K. Such hydration (and transport of additional greenhouse gases) is important to radiative forcing of Earth?s climate, as it can exacerbate observed warming. In this talk, I will provide a summary of the DCOTSS observations, highlight unique insights from a case study where active overshooting convection was sampled, and demonstrate how DCOTSS trace gas observations can be used to improve understanding of important constraining processes.

DATE: Thursday February 22 SEMINAR TIME: Refreshments at 3 PM, Talk 3:15 - 4:15 PM SEMINAR LOCATION: EOA 1044 (Speaker remote) SPEAKER: Dr. Jhordanne Jones TITLE: Is sub-seasonal to seasonal tropical cyclone predictability changing under global warming? ABSTRACT: Subseasonal to seasonal (S2S) tropical cyclone prediction at lead times between 2 weeks to 2 months is essential for preventing disasters, safeguarding livelihoods, and disseminating early warnings for imminent storm activity before and during the hurricane season. Recent projections of global tropical cyclone (TC) activity indicate a likely global increase in the frequency and variability of the most intense TCs under global warming. Concurrently, we expect changes to the Madden Julian Oscillation (MJO), a key source of sub-seasonal predictability. Under global warming, MJO-associated precipitation and zonal wind amplitudes are projected to increase with an eastward shift of MJO-related precipitation. In this talk, I?ll use the ERA5 reanalysis data to characterize and examine observed trends in S2S Atlantic TC predictability and their association with MJO variability. Additionally, given the current uncertainty in the warming pattern simulated by global climate models, I will discuss the implications of the pattern effect for the MJO-Atlantic TC relationship. The key science questions I will address in my talk are: * How are Atlantic TC variability and MJO variability changing? * Which aspects of the changing MJO variability matter for S2S Atlantic TC predictability? * And what are the implications of the pattern effect for these observed trends? We look forward to seeing you there! Cheers, Allison -------------------------------------------- Allison A. Wing, Ph.D. Werner A. and Shirley B.

In this seminar, the significance of temperature monitoring within urban environments will be discussed, alongside an exploration of various methodologies currently employed. A particular focus will be placed on the use of satellite technology for urban temperature monitoring. Initially, the seminar will showcase the application of GOES-R satellites in analyzing the diurnal characteristics of the Surface Urban Heat Island (SUHI) effect across 120 major U.S. cities. A clustering method will be employed to categorize SUHI patterns and identify underlying factors influencing these patterns. Subsequently, the seminar will show the integration of GOES-R and ECOSTRESS LST estimates, highlighting a novel approach that employs a machine-learning (specifically, XGBoost) based method for downscaling GOES-R data to ECOSTRESS resolution. This technique's potential to mitigate socioeconomic disparities within the Chicago area will also be examined, showcasing the broader implications of advanced LST measurement technologies. -------------------------------------------- Allison A.

DATE: Thursday February 22 SEMINAR TIME: Refreshments at 3 PM, Talk 3:15 - 4:15 PM SEMINAR LOCATION: EOA 1044 (Speaker remote) SPEAKER: Dr. Jhordanne Jones TITLE: Is sub-seasonal to seasonal tropical cyclone predictability changing under global warming? ABSTRACT: Subseasonal to seasonal (S2S) tropical cyclone prediction at lead times between 2 weeks to 2 months is essential for preventing disasters, safeguarding livelihoods, and disseminating early warnings for imminent storm activity before and during the hurricane season. Recent projections of global tropical cyclone (TC) activity indicate a likely global increase in the frequency and variability of the most intense TCs under global warming. Concurrently, we expect changes to the Madden Julian Oscillation (MJO), a key source of sub-seasonal predictability. Under global warming, MJO-associated precipitation and zonal wind amplitudes are projected to increase with an eastward shift of MJO-related precipitation. In this talk, I?ll use the ERA5 reanalysis data to characterize and examine observed trends in S2S Atlantic TC predictability and their association with MJO variability. Additionally, given the current uncertainty in the warming pattern simulated by global climate models, I will discuss the implications of the pattern effect for the MJO-Atlantic TC relationship. The key science questions I will address in my talk are: * How are Atlantic TC variability and MJO variability changing? * Which aspects of the changing MJO variability matter for S2S Atlantic TC predictability? * And what are the implications of the pattern effect for these observed trends? We look forward to seeing you there! Cheers, Allison -------------------------------------------- Allison A. Wing, Ph.D. Werner A. and Shirley B.

DATE: Friday March 1 SEMINAR TIME: 3 - 4 PM SEMINAR LOCATION: EOA 1050 (Speaker in person, Zoom link available on request) SPEAKER: Prof. Suzana Camargo TITLE: Tropical Cyclone Projections using Environmental Proxies and Statistical-Dynamical Downscaling ABSTRACT: In the first part of this talk, I?ll give an overview of the current state-of-the art knowledge of the influence of anthropogenic climate change on tropical cyclones, based on a recently published review paper. In the second part of the talk, I?ll describe the research that the Columbia group is doing on this topic, in particular, projections of the relationship between tropical cyclones and the El Ni?o-Southern Oscillation (ENSO), the role of ENSO diversity on these projections and how the current tropical Pacific trends in models can affect these projections. Besides results from CMIP6, a statistical-downscaling model that generates synthetic tropical cyclones from reanalysis and climate models large-scale fields will be presented. I will show the results obtained when downscaling the CMIP6 models and what we can learn from them. We look forward to seeing you there! Cheers, Allison ??????????????????

Colloquium - 499 DSL Seminar Room Abstract: Recent advances in data-driven modeling approaches have proven highly successful in a wide range of fields in science and engineering. In this talk, I will briefly discuss several ubiquitous challenges with the conventional model development / discretization / parameter inference / model revision loop that our methodology attempts to address. I will present our weak form methodology which has proven to have surprising performance and robustness properties. In particular, I will describe our equation learning (WSINDy) and parameter estimation (WENDy) algorithms. Lastly, I will discuss applications to several benchmark problems, illustrating how our approach addresses several of the above issues and offers advantages in terms of computational efficiency, noise robustness, and modest data needs (in an online learning context).

In this seminar, the significance of temperature monitoring within urban environments will be discussed, alongside an exploration of various methodologies currently employed. A particular focus will be placed on the use of satellite technology for urban temperature monitoring. Initially, the seminar will showcase the application of GOES-R satellites in analyzing the diurnal characteristics of the Surface Urban Heat Island (SUHI) effect across 120 major U.S. cities. A clustering method will be employed to categorize SUHI patterns and identify underlying factors influencing these patterns. Subsequently, the seminar will show the integration of GOES-R and ECOSTRESS LST estimates, highlighting a novel approach that employs a machine-learning (specifically, XGBoost) based method for downscaling GOES-R data to ECOSTRESS resolution. This technique's potential to mitigate socioeconomic disparities within the Chicago area will also be examined, showcasing the broader implications of advanced LST measurement technologies. --------------- 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...
