Atmospheric sciences is a broad term that encompasses the study of the Earth's atmosphere and its various physical, chemical, and biological properties. Synonyms for atmospheric sciences include meteorology, climatology, atmospheric physics, atmospheric chemistry, and atmospheric dynamics. Meteorology specifically deals with the study of weather patterns and atmospheric phenomena such as hurricanes and tornadoes, whereas climatology focuses on long-term weather patterns and climate change. Atmospheric physics deals with the physical properties of the atmosphere, such as its temperature, pressure, and density. Atmospheric chemistry deals with the chemical composition of the atmosphere, including pollutants and greenhouse gases. Lastly, atmospheric dynamics studies the movement and circulation of air in the atmosphere.
