He will a talk **at the colloquium of SC with the title *Towards the combination of physical and data-driven forecasts for Earth system prediction*? today Wednesday March 1st starting at 3:30 in 499DSL. If you would like to join by zoom: https://fsu.zoom.us/j/94273595552 He is also available to talk with other scientist during his visit. If you are interested please contact Olmo Zavala osz09 at fsu.edu ASAP. *Abstract:* Due to the recent success of machine learning (ML) in many prediction problems, there is a high degree of interest in applying ML to Earth system prediction. However, because of the high dimensionality of the system, it is critical to use hybrid methods which combine data-driven models, physical models, and observations. I will present two such hybrid methods: Ensemble Oscillation Correction (EnOC) and the multi-model ensemble Kalman filter (MM-EnKF). Oscillatory modes of the climate system are one of its most predictable features, especially at intraseasonal timescales. It has previously been shown that these oscillations can be predicted well with statistical methods, often with better skill than dynamical models. However, they only represent a portion of the signal, and a method for beneficially combining them with dynamical forecasts of the full system has not previously been developed. Ensemble Oscillation Correction (EnOC) is a method which corrects oscillatory modes in ensemble forecasts from dynamical models. I will show results of EnOC applied to forecasts of South Asian monsoon rainfall, outperforming the state-of-the-art forecasts on subseasonal-to-seasonal timescales. A more general method for combining multiple models and observations is multi-model data assimilation (MM-DA). MM-DA generalizes the variational, Bayesian, and minimum variance formulation of the Kalman filter. Here, I will show how multiple model ensembles can be combined for both DA and forecasting in a flow-dependent manner using a multi-model ensemble Kalman filter (MM-EnKF). This methodology is applied to multiscale chaotic models and results in significant error reductions compared to the best model and to an unweighted multi-model ensemble. Lastly, I will discuss the prospects of using the MM-EnKF for hybrid forecasting.

Hopefully you can be there in person. If not the zoom link for his talk is https://fsu.zoom.us/j/95943330514?pwd=VmZkOUN6WXlLR2kwRnBaLy9nbEdDQT09 Meeting ID: 959 4333 0514 Passcode: 632310 Title: Advancing High-Impact Weather Hazard Forecasting with Machine Learning Speaker: Dr. Aaron Hill (Colorado State University) Abstract: Weather hazards associated with deep convection (e.g., excessive rainfall, tornadoes, large hail, and severe wind) are often the most costly natural disasters annually. Prediction of these hazards is hindered by their localized nature and the inability of sophisticated numerical weather prediction (NWP) models to explicitly represent processes that result in hazardous weather. Artificial Intelligence (AI) and Machine Learning (ML) techniques have emerged recently as alternative methods to forecast high-impact weather hazards, and they have proven particularly skillful and valuable in their ability to explicitly forecast hazard occurrence and location (e.g., 40% chance of hail within 40 km of a point). One specific area that AI and ML have been used in the meteorology domain is postprocessing of NWP model output, taking advantage of the mathematical and statistical properties of the ML methods and their ability to process large and complex datasets, to create prediction systems capable of generating real-time forecasts of weather hazards. One example is the Colorado State University Machine Learning Probabilities (CSU-MLP) prediction system which is trained to relate historical records of high-impact weather with simulated environments from an NWP model. The ML system identifies the well-studied synoptic patterns that support high-impact weather and can be examined to better understand the ingredients for these events. The CSU-MLP has undergone significant development over recent years and is now being routinely used in operational forecasting environments, including the Weather Prediction Center, Storm Prediction Center, and local National Weather Service offices. Underlying the development of the CSU-MLP, and ML prediction systems more generally, is a decision about how to define weather events. Whereas tornadoes, severe hail, and severe wind have clear definitions (e.g., severe hail is >1? in diameter) and historical records reflect these definitions, excessive rainfall and flash flooding are ill defined. Does 2 inches of rain in 3 hours produce the same impacts in Idaho as it does in Florida? Reports of flash flooding are also inconsistently reported across the country due to varying definitions of events. As a result, development of the CSU-MLP forecast system has considered a number of definitions of excessive rainfall, including radar-derived average recurrence intervals (ARIs) and local storm reports, to produce a skillful forecast system. This talk will focus on these developments and provide a brief overview of the CSU-MLP system and forecast skill derived from high-resolution NWP model output as well as a coarser global model (i.e., the Global Ensemble Forecast System). Interpretability and explainability methods will be introduced to demonstrate what can be learned about the forecast problem, including how the ML models are learning relevant synoptic and mesoscale dynamics that we know exist, which is vital to building trustworthy products. Finally, the highlights/challenges of transitioning AI research to operational forecast centers will be discussed. -------------- next part -------------- An HTML attachment was scrubbed...

The sampled region was stratified vertically by distinct temperature layers and horizontally into a stratiform region on the west side, and a region of elevated convection on the east side. In the stratiform region, precipitation formed near cloud top as polycrystalline crystals. No supercooled water was present. Polycrystalline habits occurred through the cloud depth, implying that the cloud top region was the primary source of particles. Total number concentration slightly decreased with depth, consistent with growth by vapor deposition and aggregation. In the convective region, new particle habits were observed within each temperature-defined layer along with detectable amounts of supercooled water, implying that ice particle formation occurred in several layers. Total number concentration decreased from cloud top to the -8?C level, consistent with particle aggregation. At temperatures >-8?C, ice particle concentrations in some regions increased to >100 L-1, suggesting secondary ice production occurred at lower altitudes. Recent work also shows that cloud top phase was predominantly liquid within the convective region and predominantly ice within the stratiform region. WSR-88D reflectivity composites during the sampling period showed a weak, loosely organized banded feature. The increase in reflectivity associated with the easternmost band was consistent with the melting ice particles.? A conceptual model of precipitation growth processes within the comma head will be presented. Regards, Mark -------------- next part -------------- An HTML attachment was scrubbed...

SEMINAR LOCATION: EOA 1044 SPEAKER: Dr. Christopher Landsea TITLE: The Atlantic Basin Hurricane Database Re-analysis: Re-examining Past Hurricanes to Better Prepare for the Future ABSTRACT The Hurricane Database, known as HURDAT2, is the main historical archive of all tropical storms, subtropical storms, and hurricanes in the North Atlantic Basin, which includes the Caribbean Sea and Gulf of Mexico, from 1851 to the present. HURDAT2 is maintained and updated annually by the National Hurricane Center, as a "by-product" of operations. Today, HURDAT2 is widely used by researchers, operational hurricane forecasters, insurance companies, engineers setting building codes, emergency managers and others. Thus, its accuracy is essential, but previous work has shown that a reanalysis of HURDAT is necessary because it contains both random errors, systematic biases, and is substantially incomplete. The Atlantic Hurricane Reanalysis Project is an ongoing effort to correct the errors in HURDAT and to provide as accurate of a database as is possible with utilization of all available data in the context of today's understanding of tropical cyclones. Thus far the reanalysis has added 35 seasons (1851-1885) into the database and has officially revised nearly a century (1886-1970) of additional seasons. These 120 seasons started with only having qualitative historic records along the coast and from ships at seas (if they successfully returned from an encounter with a hurricane) and progressed to an era of coastal radars, Hurricane Hunter aircraft, and the first generation of weather satellites. The genesis, track, intensity, status, and decay of each existing tropical cyclone has been reassessed for this period, and previously unrecognized tropical cyclones have been discovered, analyzed, and recommended to the Best Track Change Committee for inclusion into HURDAT. Changes to the number of tropical storms, hurricanes, major hurricanes, accumulated cyclone energy, and U.S. landfalling hurricanes are documented. An overview of the reanalysis methodology will be provided and results will be put into context of understanding hurricane climate variability and change. -------------- next part -------------- An HTML attachment was scrubbed...

The primary objective of this study is to seek a general explanation for the quasi-linear OLR-TS relation that remains valid regardless of the strength of the atmospheric window?s narrowing effect on planetary thermal emission at higher temperatures. The physical understanding of the quasi-linear OLR-TS relation and its slope is gained from observation analysis, climate simulations with radiative-convective equilibrium and general circulation models, and a series of online feedback suppression experiments. The observed quasi-linear OLR-TS relation manifests a climate footprint of radiative (such as the greenhouse effect) and non-radiative processes (poleward energy transport). The former acts to increase the meridional gradient of surface temperature and the latter decreases the meridional gradient of atmospheric temperatures, causing the flattening of the meridional profile of the OLR. Radiative processes alone can lead to a quasi-linear OLR-TS relation that is more steeply sloped. The atmospheric poleward energy transport alone can also lead to a quasi-linear OLR-TS relation by rerouting part of the OLR to be emitted from a warmer place to a colder place. The combined effects of radiative and non-radiative processes make the quasi-linear OLR-TS relation less sloped with a higher degree of linearity. In response to anthropogenic radiative forcing, the slope of the quasi-linear OLR-TS relation is further reduced via stronger water vapor feedback and enhanced poleward energy transport. -------------- next part -------------- An HTML attachment was scrubbed...

These threats ultimately affect marine turtle reproductive output, numbers, and population stability. As a result of ?these threats, some populations of marine turtles have been dramatically reduced and are now threatened. This presentation will highlight several research projects being conducted to quantify some of the most pressing ?threats to marine turtles as well as describe different systematic conservation planning approaches used to mitigate threats. Approaches presented can be applied to other marine taxa and systems. -------------- next part -------------- An HTML attachment was scrubbed...
