Weather: A type of atmospheric condition that describes the state of the Earth's atmosphere at a specific moment and location. It encompasses various elements that can change over short periods and small areas.
Atmosphere: A layer of gases that surrounds the Earth, commonly referred to as air. It acts as a protective envelope and is composed of different layers, with the lowest layer called the troposphere where most weather phenomena occur.
Meteorology: The scientific discipline that systematically studies weather and how it changes over time. It provides the foundation for understanding weather patterns and developing methods to forecast future conditions.
Forecast: The act of predicting or determining the weather in advance, based on observations and scientific analysis.
