Abstract

Rainfall estimation plays a crucial role in weather forecasting, water resource management, agriculture planning, and disaster prevention. Accurate prediction of rainfall patterns is challenging due to the complex and nonlinear relationships among various meteorological parameters such as temperature, humidity, atmospheric pressure, wind speed, and cloud cover. Traditional statistical approaches often struggle to capture these complex interactions, resulting in lower prediction accuracy. To overcome these limitations, this study proposes a machine learning-based approach for rainfall estimation that leverages historical weather data to improve prediction performance. The proposed system utilizes supervised machine learning algorithms to analyze large-scale meteorological datasets and identify patterns associated with rainfall occurrence and intensity. Data preprocessing techniques such as normalization, missing value handling, and feature selection are applied to enhance model performance. Various machine learning models, including Decision Trees, Random Forest, Support Vector Machines, and Artificial Neural Networks, are trained and evaluated to determine the most effective approach for rainfall estimation. The trained models learn complex nonlinear relationships between environmental variables and rainfall levels, enabling more accurate predictions compared to traditional techniques. Experimental results demonstrate that the machine learning-based approach significantly improves rainfall estimation accuracy and provides reliable forecasts. The system can assist meteorological agencies, farmers, and disaster management authorities in making informed decisions related to irrigation planning, flood prevention, and water resource allocation. Overall, the proposed framework highlights the potential of machine learning techniques in enhancing rainfall estimation and contributing to more effective climate monitoring and weather prediction systems
