- 1. Atmospheric physics is the branch of meteorology and physics that studies the Earth's atmosphere, its processes, and interactions with the land, oceans, and biosphere. It delves into the behavior of the atmosphere to understand weather patterns, climate change, air quality, and other atmospheric phenomena. Scientists in atmospheric physics use a combination of observational, experimental, and modeling techniques to study the complex interactions of gases, particles, radiation, and energy within the atmosphere. By researching atmospheric physics, experts aim to improve our understanding of the Earth's climate system and make predictions about future changes in the atmosphere.
