Sunday, December 8, 2013 7:56 p.m. Were all familiar with Isaac Newton. You know, that “apple” guy. Or was it a peach? Either way, I’m sure most of you are also familiar with his second law, which says that F=ma, or that Force = mass*acceleration. There are three types of horizontal forces in the atmosphere […]
Cold Nights and Our Urban Heat Island
Saturday, November 23, 2013 5:43 pm This picture was taken at Joint Base Lewis-McChord last November by YouNews contributer Jilma V.Diaz-Demangue and was retrieved with permission from KOMO’s website. Isn’t that a beautiful picture above? It looks to be some sort of Japanese Maple leaf. I have one of those trees in my backyard, and […]

ATMOS 301: Thermodynamics of Moist Air
Thursday, October 31, 2013 10:00 p.m. We’ve already gone through a couple of variables representing the amount of water vapor in the air. These are e, the partial pressure of water vapor, and T_v, the virtual temperautre, which is equal to 1/ε*T. There are some we haven’t gone over though, so I’ll go over them […]

ATMOS 301: Dry Adiabatic Processes
Thursday, October 31, 2013 8:37 p.m. An adiabatic process is a process in which a material undergoes a change in its physical state without releasing or extracting any heat from the atmosphere. In other words, dq = 0 in the equation below, where dq = change in thermal energy (this is the first law of […]
ATMOS 301: The First Law of Thermodynamics
Thursday, October 31, 2013 5:54 p.m. Our third law that we will concern ourselves with is the first law of thermodynamics. It will be the third of the “big six” we will look at for now. Here’s the law. This law says that the heat added to a certain mass of a gas is equal […]
ATMOS 301: The Hydrostatic Equation
Thursday, October 31, 2013 3:20 a.m. I got a lot of sleep today, OK? So I’m allowed to do this. Plus, I don’t have class until 1:30 tomorrow. You ever feel your ears pop in an airplane? That’s because you are going into the upper levels of the atmosphere where the pressure is lower. Remember, […]
ATMOS 301: Equation of State
Happy Halloween! Our professor told us there are six laws that govern the atmosphere. Today, we just finished talking about Newton’s 2nd Law, which, as opposed to just being F=ma, is F = 1/(ρ)*gradient(P)*(fk X v)*av. I think. I still have to review that… today’s lecture was more confusing than why Rebecca Black ever […]
ATMOS 301: Troughs, Ridges, Waves, and Fronts
Wednesday, October 30, 2013 10:40 p.m. It almost sounds like it could be a Dr. Seuss poem. Troughs, ridges, waves and fronts. Ditches, mountains, surfboards, and stunts. Anyway, this will be the last of my “light duty” reviews/online lectures/blogs. The next section will be on gas laws and atmospheric thermodynamics. I’ll try and write them […]
ATMOS 301: Surface Station Models
Wednesday, October 30, 2013 9:16 p.m. One thing I never really paid attention to coming into this class was the surface station models. They are helpful and all, but they are difficult to look at. I mean, take a look at this chart below. It’s ugly enough as is, and to think that it’s a […]
ATMOS 301: Composition and Fundamental Physics
Wednesday, October 30, 2013 11:24 a.m. Greetings everybody. I hope you’ll forgive me for my lack of recent posts. You see, there’s this thing called college, and, well, it has these things called midterms. And these midterms, well, they take up a fair amount of your time and energy. And by a fair amount, I […]
