Any astrophysics student would know the significance of Trenberth's energy budget in modeling the earths atmosphere.
Why?
With no proper energy budget, any models of earths atmosphere are speculation. Currently models use Trenberth's budget to ensure their models are within parameters regarding energy in vs energy out, how much is used in the process and so on.
Poopie you sir are a liar..
So you're saying that the fully 3d models are supposed to recreate the results of an analytic model with a flat earth? Why?
Good question why not ask them instead of calling us all liars?
There is a great deal of technical reasons. The first being the difficulty of it all. Think about it, a simple model one can look at to get a guideline of just how much energy enters, exists and does work in the entire atmosphere. How much is left behind? How much exits? How much gets spent in the various processes? How much is lost from reflection, refraction? How much is used to warm the surface vs how much to warm the atmosphere? Now add in factors like wind and air flow, ocean currents, sea breezes. Then there is the various different gasses that effect that energy flow, which vary by density and content with temperature as well as other things like volcanoes. Then figure out how much heat is escaping from our molten core. Then make it vary for day, night, sunrise, sunset, storms, clouds, etc and so on.
Now take all of that into account and give an average energy usage against energy input. And make sure to take into account the variable distance from the sun and the orbital rotation as well as natural wobble of our planets spin, and don't forget seasonal changes.
Take all of that and represent your findings accurately using a simple number...
See the problem yet? Trenberth had no choice but to average the thing as best he could. So he went with a flat disk and near twilight conditions to give the simple model and numbers needed for the base.
We don't have the computer power to model an accurate energy budget based on all the data. Dude we are still working on mapping the human genome, how can we model all of that accurately yet? We can't plain and simple.
We are getting closer now. The latest from NASA for example, states that previous estimates of energy leaving earth were far too low. Turns out there is a lot more leaving now than previously thought. They found this out because the technology has improved.
You aren't understanding that there has to be an energy budget to make any accurate climate models. Without a budget to go by, there is no way to ascertain if the model is accurate on its energy usage according to observed data as well as that from the sun our source of energy. Extra energy coming in changes the climate, just as less energy in would.
Now you want to maintain you're a atmospherical modeler, be my guest, but I don't think I would need to explain this to one...
