Rainfall prediction is critical for raising awareness about the potential risks associated with extreme weather events and enabling individuals to take proactive safety measures. This study leverages machine learning algorithms to forecast rainfall, recognizing the significant impact that both insufficient and excessive rainfall can have on rural and urban areas. Due to the complex nature of rainfall, which is influenced by atmospheric, oceanic, and geographical factors, predicting rainfall remains a challenging task. To address this, the research employs a variety of data preprocessing techniques, including outlier analysis, correlation analysis, and feature selection. Several machine learning models are applied, including Naive Bayes (NB), Decision Tree, Support Vector Machine (SVM), Random Forest, and Logistic Regression, to develop a reliable rainfall prediction model. The study places particular emphasis on selecting the most relevant features to improve the model's accuracy. Additionally, Artificial Neural Networks (ANN) are used, with feature selection enhancing their predictive performance.
To explore regional rainfall patterns, k-means clustering and Principal Component Analysis (PCA) are applied, focusing on rainfall behaviour in Australia. As part of the research, a userfriendly web application is developed using Flask, making the machine learning model more accessible to the general public. This web-based system allows users to easily interact with the rainfall prediction model and gain valuable insights into weather patterns. Overall, the study demonstrates the effectiveness of various machine learning techniques in predicting rainfall, providing valuable insights for improving preparedness and decision-making based on Australian weather data.
