Introduction to Ocean and Atmospheric Turbulence

How do planetary-scale winds and deep-ocean currents shape our global climate? Understanding the complex, chaotic nature of turbulence in fluid systems is essential for anyone looking to comprehend meteorology, oceanography, or environmental modeling. This text-based course guides you through the foundational physics and fluid dynamics that govern turbulent flows in both the atmosphere and the oceans. You will transition from basic concepts of fluid motion to analyzing complex, large-scale geophysical phenomena, building a strong conceptual framework for analyzing planetary fluid systems. What you'll learn: Understand key fluid dynamics terminology, including the Navier-Stokes equations and Reynolds numbers; Analyze the differences between three-dimensional isotropic turbulence and two-dimensional geophysical flows; Explore the mechanics of convection and its role in atmospheric heat transfer; Examine quasi-geostrophic and baroclinic turbulence on planetary scales; Investigate shallow water equations and their application to coastal and ocean currents; Interpret modern computational modeling approaches used to simulate turbulent systems. You will start with core physical definitions and governing equations before moving step-by-step through scaling laws, convection, and planetary-scale macroturbulence. Through clear written explanations and analytical exercises, you will develop a practical intuition for how fluids behave under rotation and stratification. This course is designed for beginners, environmental science students, and curious learners looking for a solid introduction to fluid mechanics without requiring advanced prerequisites.
