GEOS1701 Lecture Notes - Lecture 2: Thermosphere, Geosphere, Solar Irradiance
Document Summary
Weather: e ects ood events, severe storms, what crops to plant etc. To look at the interactions between environmental systems, we normally look at several di erent spheres at play. We have an atmosphere, an oceanosphere, a hydrosphere, a lithosphere, a biosphere, and a geosphere as well. The atmosphere and what happens in that really a ects the rest of the spheres, an understanding of the atmosphere and its behaviour is critical to understand the climate. Climate and weather are key controls of earth"s environmental systems have critical impacts on human civilisation: earth"s atmosphere and climate. Topic structure: atmospheric elements, energy and circulation, climate and weather patterns, climate change: natural and human induced.
