Introduction
In recent years, the use of machine learning (ML) methods in meteorology has seen a significant increase. This trend is evident from the growing number of published studies utilizing ML techniques. However, despite this rise in popularity, there is a lack of meteorology-specific resources on ML terms and methods. This scarcity prompted the development of a series of papers aimed at addressing this gap and providing valuable insights for meteorologists interested in incorporating ML into their work.
The Need for Trustworthiness in Machine Learning Methods
While many ML methods are not new, there is a prevailing concern among developers that end-users may be hesitant to trust these models due to their perceived complexity and opacity. This lack of trust can hinder the adoption and application of ML techniques in meteorological research and forecasting efforts.
To address this issue, the papers aim to enhance the trustworthiness of ML methods through plain language discussions and real-world meteorological examples. By demystifying the black box nature of ML models, the goal is to improve user confidence in applying these techniques to their everyday workflow.
Introducing Key Terms and Commonly Used Methods
The first paper in the series introduces various ML methods commonly used in meteorology and defines key terms associated with ML. These include supervised learning, unsupervised learning, regression analysis, decision trees, neural networks, support vector machines (SVM), clustering algorithms, and more.
By understanding these fundamental concepts, users can gain a better understanding of how different types of data can be processed using various ML techniques. This knowledge also allows for informed decisions when selecting an appropriate method for specific applications.
A Simple Meteorological Example: Applying Machine Learning Techniques
To illustrate how these concepts can be applied within a meteorological context effectively, the first paper discusses a simple example involving precipitation prediction using historical weather data. This example outlines an end-to-end pipeline for implementing ML models, including data preprocessing, model training and evaluation, and making predictions.
The Importance of Transparency in ML Forecasts
One crucial aspect emphasized in the first paper is the importance of transparency in ML forecasts. This refers to the ability to understand how a model arrived at its predictions and whether it aligns with prior knowledge or expectations. By ensuring transparency, users can have more confidence in the reliability and accuracy of ML forecasts.
Building Upon Foundational Knowledge: Subsequent Papers
Moving forward, subsequent papers in the series will delve deeper into specific topics related to machine learning in meteorology. These may include advanced techniques such as deep learning and ensemble methods, as well as practical considerations like data quality and feature selection.
By offering practical guidance and resources, including code examples for reference, these papers aim to empower meteorologists to leverage machine learning effectively in their research and forecasting efforts.
Conclusion
In conclusion, this comprehensive series serves as a valuable reference for meteorologists seeking to navigate the complexities of machine learning. By bridging the gap between traditional meteorological practices and cutting-edge ML techniques through clear explanations and practical insights, these papers aim to foster innovation and progress within the field. With enhanced trustworthiness of ML methods, we can harness their potential benefits for advancing understanding and prediction capabilities in atmospheric science.
Recently, the use of machine learning in meteorology has increased greatly. While many machine learning methods are not new, university classes on machine learning are largely unavailable to meteorology students and are not required to become a meteorologist. The lack of formal instruction has contributed to perception that machine learning methods are 'black boxes' and thus end-users are hesitant to apply the machine learning methods in their every day workflow. To reduce the opaqueness of machine learning methods and lower hesitancy towards machine learning in meteorology, this paper provides a survey of some of the most common machine learning methods. A familiar meteorological example is used to contextualize the machine learning methods while also discussing machine learning topics using plain language. The following machine learning methods are demonstrated: linear regression; logistic regression; decision trees; random forest; gradient boosted decision trees; naive Bayes; and support vector machines. Beyond discussing the different methods, the paper also contains discussions on the general machine learning process as well as best practices to enable readers to apply machine learning to their own datasets. Furthermore, all code (in the form of Jupyter notebooks and Google Colaboratory notebooks) used to make the examples in the paper is provided in an effort to catalyse the use of machine learning in meteorology.
