Machine Learning Estimation of Maximum Vertical Velocity from Radar

1 code implementation13 Oct 2023 Randy J. Chase, Amy McGovern, Cameron Homeyer, Peter Marinescu, Corey Potvin

Updraft proxies, like overshooting top area from satellite images, have been linked to severe weather hazards but only relate to a limited portion of the total storm updraft.

Comparing Explanation Methods for Traditional Machine Learning Models Part 2: Quantifying Model Explainability Faithfulness and Improvements with Dimensionality Reduction

no code implementations18 Nov 2022 Montgomery Flora, Corey Potvin, Amy McGovern, Shawn Handler

This study is one of the first to quantify the improvement in explainability from limiting correlated features and knowing the relative fidelity of different explainability methods.

Comparing Explanation Methods for Traditional Machine Learning Models Part 1: An Overview of Current Methods and Quantifying Their Disagreement

no code implementations16 Nov 2022 Montgomery Flora, Corey Potvin, Amy McGovern, Shawn Handler

With increasing interest in explaining machine learning (ML) models, the first part of this two-part study synthesizes recent research on methods for explaining global and local aspects of ML models.

A Machine Learning Tutorial for Operational Meteorology, Part II: Neural Networks and Deep Learning

2 code implementations31 Oct 2022 Randy J. Chase, David R. Harrison, Gary Lackmann, Amy McGovern

In order to fill the dearth of resources covering neural networks with a meteorological lens, this paper discusses machine learning methods in a plain language format that is targeted for the operational meteorological community.

Global Extreme Heat Forecasting Using Neural Weather Models

no code implementations23 May 2022 Ignacio Lopez-Gomez, Amy McGovern, Shreya Agrawal, Jason Hickey

We find that training models to minimize custom losses tailored to emphasize extremes leads to significant skill improvements in the heat wave prediction task, compared to NWMs trained on the mean squared error loss.

The Need for Ethical, Responsible, and Trustworthy Artificial Intelligence for Environmental Sciences

no code implementations15 Dec 2021 Amy McGovern, Imme Ebert-Uphoff, David John Gagne II, Ann Bostrom

In fact, much can be learned from other domains where AI was introduced, often with the best of intentions, yet often led to unintended societal consequences, such as hard coding racial bias in the criminal justice system or increasing economic inequality through the financial system.

Using Machine Learning to Calibrate Storm-Scale Probabilistic Guidance of Severe Weather Hazards in the Warn-on-Forecast System

no code implementations12 Nov 2020 Montgomery Flora, Corey K. Potvin, Patrick S. Skinner, Shawn Handler, Amy McGovern

Using a novel ensemble storm track identification method, we extracted three sets of predictors from the WoFS forecasts: intra-storm state variables, near-storm environment variables, and morphological attributes of the ensemble storm tracks.
