1.INTRODUCTION
Weather forecasting is a critical aspect of modern life,
impacting various sectors such as agriculture,
transportation, energy, and disaster management. Accurate
and reliable weather predictions enable individuals and
organizations to plan their activities, optimize resource
allocation, and mitigate the impacts of extreme weather
events[1]. Traditional weather forecasting methods, based
on numerical weather prediction models, which made
significant progress over the years, but they still face
challenges in capturing the complexity of atmospheric
processes and providing precise short-term forecasts[2].
With the advent of machine learning and its remarkable
successes in various domains, the methods of weather
forecasting has also witnessed a paradigm shift. Machine
learning techniques, which involvetheuseofalgorithmsthat
can learn patterns and relationships from data, offer new
opportunities to enhance the accuracy and efficiency of
weather predictions[3].This comprehensivesurvey explores
the various machine learning mechanisms applied to
weather forecasting and provides insights into the current
state-of-the-art, challenges, and future directions.
1.1Historical Perspective of Weather Forecasting
Weather forecasting is having a long history that dates back
to ancient civilizations. Early methods of weatherprediction
involved observing natural phenomena like cloud patterns,
wind direction, and animal behavior. However, it was not
until the 19th century that bring advancements in science
and technology laid the foundation formodernmeteorology.
The invention of weather instruments, such as barometers,
thermometers, and anemometers, allowed for more
systematic data collection[4].
1.2 Machine Learning in Weather Forecasting: An
Overview
Machine learning, a subset of artificial intelligence,
empowers computers to learn from data without being
explicitly programmed. The flexibility and adaptability of
machine learning algorithms have made them increasingly
popular in various applications, including weather
forecasting. Machine learning mechanisms can be broadly
categorized into supervised, unsupervised, and
reinforcement learning[5].
Supervised Learning:Insupervisedlearning,thealgorithmis
trained on labeled data, where the input-output
relationships are known. In the context of weather
forecasting, historical weather data and corresponding
observed outcomes (e.g., rainfall, temperature) that can be
used to train the model. Once trained, the algorithm can
predict the future weather conditions based on new input
data[6].
Unsupervised Learning: Unsupervised learning deals with
unlabeled data, and the algorithm aims to find patterns and
structures within the data without explicit guidance.
