The Evolution of Weather Prediction

Traditional methods of weather prediction have a rich history, with various indigenous knowledge systems (IKS) being utilized for forecasting. These traditional methods have been honed over generations and are deeply rooted in the observations and experiences of local communities [25]. Additionally, analogue forecasting, a method with a long history in weather and climate prediction, has been widely used [26]. Furthermore, weather-typing methodologies have been commonly employed in atmospheric sciences and have a long history, especially in weather forecasting [27]. These traditional methods have been crucial for small-scale farmers in predicting drought under weather and climate uncertainty, highlighting the importance of tailoring methods to fit new environmental conditions [28]. Moreover, the incorporation of IKS into modern weather forecasting methods has been recognized as a necessity for planning farming activities [25]. The future of traditional prediction methods and the potential increase in their accuracy and reliability depend on the ability to enhance, preserve, and validate these methods [28]. The study of weather prediction systems based on fuzzy logic and the development of weather classification pattern recognition based on support vector machine demonstrate the continuous efforts to improve traditional methods using modern technology [29] [30]. These efforts reflect the ongoing evolution of traditional weather prediction methods to adapt to changing environmental and climatic conditions, while also integrating modern scientific and technological advancements.
