※ 引述《Mog (ニゑソ地球メ守ゲサ)》之銘言：
: I think that's for the pressure unit (hpa). Can you calculate
: the surface mixing ratio? Is the value something around 10s g/kg?

The data range of mixing ratio is from 0.013 to 0.019.
Equal to the value you mentioned.
The unit of mixing ratio here is kg/kg.
And for the reason of unit correctness,
unit for mixing ratio in Q2 should be set as kg/kg.

: And what's the typical value of dry static energy? Try calculate s/cp,
: does that match the typical profile of theta?
: Your calculation seems ok to me, I believe there's some unit error
: within your calculation, try to make sure every value you calculate
: make sense before you go on.

Typically, the s(dry static energy) is around 300000 to 350000,
unit is (m*m)/(s*s).
In Yanai's paper (JAS, 1973), they had showed the s profile.
Although the unit was cal/gm, and 1 joule is equal to 0.2389 cal,
after convert unit as same as Yanai showed (s*0.0002389),
the patterns and scales match in two diagrams.
