👉 Atmospheric fluid refers to the dynamic and ever-changing composition of gases, aerosols, and trace chemicals within Earth's atmosphere. It encompasses various components such as nitrogen, oxygen, argon, carbon dioxide, water vapor, and numerous trace gases including ozone, methane, and various pollutants. These fluids interact through complex physical processes like convection, diffusion, and chemical reactions, influencing weather patterns, climate regulation, and the Earth's energy balance. The fluid nature of atmospheric gases means they are constantly in motion, redistributing heat and moisture across the globe, and their interactions play a crucial role in sustaining life and shaping our environment.
