PPT-Pressure and Temperature structure of the atmosphere:

Pressure gradient controlled by hydrostatic equilibrium pressure supports weight of gas above it and because it is gas density drops with decreasing pressure combination of effects leads to efolding drop in pressure over . Essential Points. Heat, Temperature and Temperature Scales. The Electromagnetic Spectrum. Composition of the Atmosphere. Layers in the atmosphere are defined by temperature profiles. How pressure varies in the atmosphere. Ferrel. cell. Ferrel. cell. Polar cell. Fig 1. Earth’s radiation budget. What do ‘surplus’ and ‘deficit’ refer to?. What wavelength ranges are for shortwave and . longwave. ? What are their sources?. NC Essential Standard:. Compare the composition, properties, and structure of Earth’s atmosphere to include: mixtures of gases and differences in temperatures and pressure within layers.. There are . Weather vs. Climate. Weather is the condition of the atmosphere and surface at any given time.. C. limate is the average condition observed for longer time periods or long term expression of weather, typically . Objectives. Describe the composition of Earth’s atmosphere.. Explain why air pressure changes with altitude.. Explain how air temperature changes with atmospheric composition.. Describe the layers of the atmosphere.. Weather. Whether the weather be fine,. Or whether the weather be not,. Whether the weather be cold,. Or whether the weather be hot,. We'll whether the weather. Whatever the weather. Whether we like it or not. Tuesday, September 20, 2011. Objectives:. 1. Explain the composition, structure, and properties of Earth’s Atmosphere.. 2. Explain the difference between Earth’s Early Atmosphere and the current Atmosphere.. II 2017. a. aron.hill@ttu.edu. Weather Is Everywhere. University Studies/Global Studies. Climate change protocols. Fossil fuel consumption/climate change. R. enewable energy reliance. Business/Finance/Marketing/Commerce. Both deal with atmospheric phenomena. Weather. denotes the state of the atmosphere over short time scales - hours or days. Climate. denotes these phenomena over long time scales -many years or centuries. Section 11.2 – Properties of the Atmosphere 8 th Grade Earth and Space Science Class Notes Temperature Temperature – measure of the average kinetic energy of the particles in a material Higher the temperature = faster particle movement Properties of the Atmosphere Heat vs. Temperature Temperature – measure of how rapidly or slowly molecules move around. Higher the temperature = faster particle movement Heat - is the transfer of energy that occurs because of a difference in temperature between substances ). Presented By. Dr. . Banashree. . Saikia. Assistant Professor. Department of Geography. JN College,. . Boko. Structure of the Atmosphere . On the basis of the characteristics of temperature and air pressure there are four distinctive layers from the earth surface upward . Average Atmospheric Composition. Permanent. Variable. SOURCE. (to atmosphere). SINK. (removal from atmosphere). N. 2. Fixed by soil bacteria. Fixed by ocean phytoplankton. Lightning. Denitrification by anaerobic . 3. Its structure, composition and dynamics. In last week’s lecture, we focussed on how weather is generated.. The key ingredients are energy and gradients.. Last Week’s Lecture. Incoming energy from the Sun is balanced with outgoing radiative cooling of the Earth, resulting in an equilibrium temperature of about 15 °C. .
