1. Abstract
Weather Forecasting using LSTM is a deep learning and time-series forecasting project designed to predict future weather conditions from historical weather data. The system analyzes parameters such as temperature, humidity, atmospheric pressure, wind speed, rainfall, and other meteorological variables. Long Short-Term Memory (LSTM) networks are used to learn temporal dependencies and patterns within historical weather observations. The model can forecast future temperature, rainfall, humidity, or other weather parameters depending on the dataset and prediction objective.
2. Objectives
- Predict future weather conditions using LSTM.
- Analyze historical weather patterns and seasonal trends.
- Forecast temperature, humidity, rainfall, pressure, or wind conditions.
- Capture long-term dependencies in weather time-series data.
- Apply deep learning to meteorological forecasting.
- Reduce manual effort in analyzing historical weather data.
- Provide visual comparisons between actual and predicted weather.
- Develop an interactive weather forecasting interface.
- Support data-driven environmental and weather analysis.
3. Existing System
Traditional weather forecasting may use:
- Weather station observations.
- Historical weather records.
- Statistical forecasting methods.
- Meteorological models.
- Expert analysis.
- Satellite and sensor observations.
Limitations:
- Complex weather relationships can be difficult to model.
- Sudden weather changes can reduce prediction accuracy.
- Large historical datasets require extensive processing.
- Traditional statistical models may not capture all long-term temporal patterns.
- Manual analysis can be time-consuming.
