Convective mass flux encodes information about the frequency and intensity of thunderstorms and has been linked to the strength of the large-scale tropical circulation. In this talk I will introduce a new framework for quantifying changes in convective mass flux using the clear-sky energy budget. This framework shows that convective mass fluxes decrease at around 3-5 % / K under warming, when viewed at a fixed isotherm. This decrease in convective mass flux with warming is driven by a stabilization of the lapse rate and can be captured with a simple analytical model. I also revisit previous work by Held and Soden (2006), who proposed a scaling for changes in the convective mass flux with warming, and show that the Held and Soden scaling does not capture inter-model spread in mass flux changes under warming. This work provides a quantitative constraint on changes in convective mass flux with warming and establishes a new framework for understanding changes in convection in a warming climate. ??????????????????

ABSTRACT: The evolution of the marine atmospheric boundary layer as it is advected inland during the warm season plays a critical role in the initiation?or suppression?of convection in the Great Lakes coastal environment. Gaining a deeper understanding of these transitions and their effects on convection is of significant importance, particularly given the large population in many coastal areas. To address this, the National Science Foundation-funded Maritime to Inland Transitions Towards ENvironments for Convection Initiation (MITTEN-CI) campaign was conducted in July 2024, with the goal of developing an extensive dataset that could effectively characterize these transitions. Over-lake thermodynamic and kinematic profiles were observed by Uncrewed Aircraft Systems (UAS), while sampling of boundary layer spatial and temporal variability over land occurred along a 120 km long shore-perpendicular transect including six flux towers, two mobile mesonets, multiple radiosonde launch sites, a Doppler LiDAR, and two mobile Ka-band Doppler radars. This dataset enables hypothesis testing that will result in new knowledge of processes that support the development of instability maxima on the cool side of lake-breeze fronts (LBFs), the potential for diffuse LBFs to exist embedded within synoptic-scale onshore flow and influence CI, the prevalence of misovortices at intersections of horizontal convective rolls and the LBF, RKW theory?s relation to the vertical structure of the LBF, and the influence of entrainment on the thermodynamics and structure of the boundary layer and the LBF. This talk will provide an overview of the MITTEN-CI campaign, highlighting the unique data collected, with additional insights provided through analysis of relevant idealized simulations. ??????????????????

Validating NASA?s IMERG Rainfall analysis with Florida Automated Weather Network Observations (FAWN) By Cameron Matthis Description: IMERG is a widely used gridded global dataset, while FAWN is a high-resolution in-situ dataset specific to Florida. Given IMERG?s extensive use, it is crucial to validate its rainfall analysis using ground-based observations like FAWN. In this study, I will assess IMERG and FAWN data across multiple temporal scales, including the time mean, seasonal, interannual, and diurnal timescales, to evaluate their strengths and weaknesses Drivers of Summer Mixed-Layer Cooling in the Northwestern Arabian Sea By Ethan Wright Description: The northwestern Arabian sea experiences large scale mixed-layer cooling on average throughout the summer months of June, July and August. Global HYCOM output is used to analyze the seasonal development and drivers of this cooling. A mixed-layer heat budget analysis at the model grid cell level is used to analyze the dominant space-and-time patterns of summer cooling with emphasis placed on contrasting the mesoscale and large-scale processes that affect the summer cooling off the coast of Oman. Recent Changes in Moisture Flux Patterns over India: Implications for ISMR By Amarjeet Vidyarthi Description: Pure rotational and divergent components of moisture flux are computed and analyzed to investigate the recent changes in moisture flux patterns over India. This study is using the ERA-5 datasets. Our study finds that the rotational component of the moisture flux, which relates to moisture transport is strengthened in recent decades. This is attributed to the non-uniform rate of change of tropospheric air temperature in the lower and middle troposphere from the rising land-ocean thermal contrast. The rising trend in temperature is related to concomitant increase in the precipitable water content (PWC) over the Indian landmass especially in the middle troposphere. Moreover, the relatively higher warming in the middle troposphere results in stabilizing the atmosphere. Therefore, we also observe an increase in the fraction of stratiform precipitation in recent period resulting in increased mid-atmospheric diabatic heating which enhances the mid-tropospheric southwesterly moisture flux, in the recent decades.

Colloquium - 499 DSL Seminar Room Abstract: The multispecies coalescent (MSC) model applies coalescent theory to gene evolution within and among reproductively isolated populations ("species") to estimate a species tree in the face of potential gene tree conflict resulting from deep coalescence. We are exploring the use of particle filtering (PF) to sample from the MSC posterior distribution, providing a fully Bayesian and easily parallelized alternative to traditional Metropolis-Hastings MCMC approaches. The method we propose samples first from the joint posterior distribution of gene and species trees, then samples species trees conditional on gene trees sampled previously, employing PF for both. Analyses of simulated and empirical datasets yield results comparable to state-of-the-art Bayesian MCMC approaches but at a fraction of the computational cost.

Colloquium - 499 DSL Seminar Room Abstract: Compositionally complex materials, represented by high-entropy alloys and ceramics, have primarily been used as structural materials since their initial discovery. Recently, interest in their potential for energy storage and conversion has surged. However, this excitement is often accompanied by confusion, as researchers grapple with the need to complicate material composition beyond vague concepts like the "cocktail effect." This talk aims to clarify some fundamental pictures of compositionally complex energy materials (CCEM), illustrated through case studies on high-entropy battery materials and electrocatalysis. Inspired by the ongoing revolution of AI in science, we will also showcase our recent efforts in developing universally adaptable machine learning models for CCEMs. Our findings suggest that, in many cases, machine learning challenges in CCEM stem more from data limitations rather than the need for sophisticated neural network architectures. A well-designed dataset, enriched with the right domain knowledge, can deliver powerful insights even with simple models.

Below are the seminar title, abstract, and Marco's short bio. Let me know if you have any questions. Look forward to seeing you at the seminar. -Ming 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. Bio: Marco Larra?aga holds a Bachelor's degree in Oceanology and a Master's degree in Physical Oceanography. He later obtained his Ph.D. from the Laboratory of Geophysical and Spatial Oceanography Studies (LEGOS) in France, where he explored ocean-atmosphere-wave interactions and their influence on the dynamics of the Gulf of Mexico. Currently, Marco is a postdoctoral researcher at the Center for Ocean-Atmospheric Prediction Studies (COAPS), where he studies the ocean dynamics of the Gulf of Mexico, with a particular interest in air-sea interactions and the factors leading to the separation of eddies from the Loop Current. -------------- Ming Ye, Ph.D. Professor in Hydrogeology Department of Earth, Ocean, and Atmospheric Science Department of Scientific Computing Office: 3015 EOAS Building (1011 Academic Way) Phone: 850-645-4987 Florida State University Tallahassee, FL 32306-4520 Email: mye at fsu.edu http://earth.eoas.fsu.edu/~mye/ -------------- next part -------------- An HTML attachment was scrubbed...

First, at the current time it appears none in EOAS suffered injuries from the tragic events only one building over yesterday. But, it is early in the investigation, so that could change. Regardless, several others on campus were not as fortunate, and we deeply mourn for them. Several in EOAS were in other buildings on campus (including the Union) either due to lunch, classes, or meetings (including me), unable to return to EOAS to help their friends and colleagues during the lockdown. It was indeed traumatizing for all. I have more than one personal experience with this type of event, unfortunately. By pure coincidence, I was only a hundred feet away when the Hot Yoga incident happened in 2018, and I can tell you the images and memories of that still haunt me today. In college myself in 1996, I missed being a potential victim of a mass shooting at Penn State by only 15 minutes as I walked across campus to classes. I URGE you to seek out counseling to help you recover from yesterday?s trauma. Even if it?s not evident right now, it may be needed as time goes on for some of you. FSU?s Counseling and Psychological Services team is available at 850-644-TALK (8255). Many in our EOAS community stepped up yesterday to protect each other during the threat: Staff, Faculty, and Students. Whether it was sharing information as they received it, barricading doors, or simply keeping their friends and students calm by selflessly remaining in the classroom to comfort them -- they are heroes for defending and supporting us all. I profusely thank them for that courage. Campus has been deemed secure and safe ? and today (Friday) has been designated as a day to retrieve your belongings on campus if you had to leave them there. I will be in the EOAS building starting approximately 10am for those who need to enter and wish to be escorted to retrieve their belongings. Card swipe will be needed to enter. Starting at 10am, if you wish for me to escort you to your office, my email is rhart at fsu.edu and you can email me with your name when you arrive. FSU has asked that you show me your FSU ID before entering, so please bring that with you. Finally, several doors and door windows in the building were damaged during the evacuation process yesterday. I will be doing an inventory of those rooms today. If you find your office door compromised, please email me (rhart at fsu.edu) so I make sure it?s on the list. Should your door, door lock, or door window be compromised, please do take any personal valuables with you when you visit today. I will be in Room 2008D if you wish to talk today from 10am to 5pm.
