area of a sphere
|
pi * r squared

|
surface area of a sphere
|
4 * pi * r squared
|
|
|
how much of the earth's atmosphere is contained below 10 km
|
80%
|
|
|
what covers what percentage of the earth
|
70 percent
|
|
|
mass of the atmosphere
|
5.26 x 10^18 kg
|
|
|
mean surface pressure
|
1.012 x 10^5 Pa
|
|
|
surface temperature
|
288 K
|
|
|
mean surface density
|
1.235 kg/m3
|
|
|
hecto
|
100
|
|
|
converstion of pascals to bars
|
1 bar = 100000 Pa
1hPa = 1mbar |
|
|
gas constant for dry air
|
287.05 j//kgK
|
|
|
gas constant
|
8314 j/kmol K
does that equate to kg? |
|
|
potential density anomaly
|
sigma = density - 1000 km/m3
|
|
|
potential density
|
density a parcel would acquire adiabatically when brought from pressure 0 to current pressure
|
|
|
equations of state
|
describe the state of a variable under given conditions
ex: equation of state for density rho(T,S, P) density as a funciton of tempreature, salinity and pressure |
|
|
Newton
|
kgm/s2 and is a unit of force
|
|
|
Joule
|
amount of energy applied while doing work, can be considered a N*m or kgm2/s2
|
|
|
Watt
|
J/S or kgm2/s3
|
|
|
Troposphere
|
lowest level of the atmosphere, it is where 85% of where the water vapor resides. temperature decreases with height. where most of the weather occurs
|
|
|
Stratosphere
|
second lowest level of the atmosphere and where ozone peaks. Temp increases with height. It is highly stratified and not well mixed
|
|
|
Mesosphere
|
temperature decreases with height. goes until about 85 km above the surface level. Least understood layer
|
|
|
Thermosphere
|
temp increases with height. UV is absorbed by oxygen which helps warm and there is a dissociation of carbon dioxid
|
|
|
volume of the ocean
|
1.332 x 10^18 m3
|
|
|
sigma t
|
density of a parcel of water at the in situ S and T but as it would exist at surface pressure
incompressible fluid |
|
|
sigma theta
|
aka potential density, uses potential temperature instead of in situ temperature so then it refers to adiabatic movement when brought to a reference pressure
|
