a. Equilibrium value can be changed when one of the inputs is changed – new equilibrium value is achieved i. i.e. Burn fossil fuels – release carbon dioxide in the atmosphere – changes energy balance resulting in global warming 23. Explain how weather is a result of a disturbance in the atmosphere a. Atmosphere (Nature) doesn’t like to be “disturbed” it always tries to reach a state of equilibrium i. Weather is a result of a thermal disturbance in the atmosphere due to unequal heating resulting from the tilt of the earth with respect to sun b. Atmosphere attempts to remove the disturbance and reach thermal equilibrium 24. What is the Law of Conservation of Energy? Give an example a. The principle of conservation of energy states that energy cannot be created or destroyed, although it can be changed from one form to another. Thus in any isolated or closed system, the sum of all forms of energy remains constant. The energy of the system may be interconverted among many different forms— i. mechanical, electrical, magnetic, thermal, chemical, nuclear, and so on The b. Earth’s climate is a solar powered system. Radiant Energy from the Sun is converted into 25. Explain the concept of Mass Balance using a circulation in the atmosphere. a. This principle is simply a statement that in a continuous fluid (with no walls or partitions) one cannot empty out a region from its mass - when fluid is taken out from one place, surrounding fluid rushes in to take up that space. b. Mass balance in the Atmosphere results in Circulations c. If something rises in the atmosphere resulting in a loss of mass (rising hot air), somewhere else something will try to add mass be (descending cold air) i. Low Pressure – Rising ii. High Pressure - Sinking 26. Explain how a low pressure at the surface results in convergence. a. Convergence i. More coming in than going out ii. increase mass iii. i.e. at surface: Low Pressure

b. At the surface Results in rising air : uplift 27. What is vorticity in the atmosphere. Give one example a. Any time there is a change in direction in the upper atmosphere there is vorticity i. Vorticity is spin or turning of an air parcel in the atmosphere 1. When there is vorticity there is divergence and convergence ii. Vorticity is reported on weather maps iii. Cutoff lows and omega blocks have large amounts of vorticity 28. List three properties of the atmosphere that show it exhibits fluid-like behavior? a. Because it is a fluid system, the atmosphere is capable of supporting a wide spectrum of motions. i. Buoyancy ii. Convection iii. Pressure varies with depth 29. What are three types of circulation in the atmosphere a. Circulation Examples - i. El Nino and La Nina ii. Gyres (Ocean) iii. Monsoons 30. What are three things that may occur in the atmosphere as moist air gets cooler a. 31. What does the acronym RECC stand for? Provide a sketch. a. RECC - A low surface pressure or a convection causes convergence at the surface i. Rise, Expand, Cool, Condense

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
