Episode 30: Climate System

Send us Fan Mail In this episode of the podcast, I have talked about “Earth’s Climate System.” Topics Covered: Climate System Weather and Climate Earth’s Climate History Components and their interactions How humans are changing the climate Inertia The sun and the global energy balance Global and hemispheric variability Extreme Events Global Air Circulation Non Rotating Earth Rotating Earth Hadley Cell Ferrel Cell Polar Cell Climate Regions Records of Climate Change Long term and Short Term Cycles in the Climate System Additional Info: Paleoclimatology: Paleoclimatology is the study of past climate over a great period of the Earth's history. It uses evidence from ice sheets, tree rings, sediments, coral, and rocks to determine the past state of the climate. It demonstrates periods of stability and periods of change and can indicate whether changes follow patterns such as regular cycles. Climate Models: Climate models use quantitative methods to simulate the interactions of the atmosphere, oceans, land surface and ice. They are used for a variety of purposes; from the study of the dynamics of the weather and climate system, to projections of future climate. All climate models balance, or very nearly balance, incoming energy as short wave (including visible) electromagnetic radiation to the earth with outgoing energy as long wave (infrared) electromagnetic radiation from the earth. Any imbalance results in a change in the average temperature of the earth. The most talked-about applications of these models in recent years have been their use to infer the consequences of increasing greenhouse gases in the atmosphere, primarily carbon dioxide. These models predict an upward trend in the global mean surface temperature, with the most rapid increase in temperature being projected for the higher latitudes of the Northern Hemisphere. Models can range from relatively simple to quite complex: Simple radiant heat transfer model that treats the earth as a single point and averages outgoing energy this can be expanded vertically (radiative-convective models), or horizontally finally, (coupled) atmosphere–ocean–sea ice global climate models discretise and solve the full equations for mass and energy transfer and radiant exchange.
