How do humans interact with the atmosphere?

How do humans interact with the atmosphere? There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth’s atmosphere, ocean and land surface to increase … […]

What is perturbation technique?

What is perturbation technique? A mathematical technique to eliminate linear terms in an equation in order to retain the nonlinear (turbulence) terms. Variables such as potential temperature (θ) or velocity (U) can be partitioned into mean (slowly varying) and perturbation (rapidly varying) components. Why do we use perturbation? Perturbation is used to find the roots […]
