The nearshore temperature of the model is too high

#1 Unread post by 22jzhou »

Hello everyone, when I simulated the northeastern part of the South China Sea in summer, the near-shore part of the temperature never dropped. I tried switching the mixture from MY-2.5 to LMD, but failed to bring the temperature down. I would like to ask you, if you want to reduce the temperature near the shore part of the good advice? Here's my.h file:

Here are the relevant Settings from my.in file:
Hadvection == A4 \ ! temperature
A4 ! salinity

Vadvection == A4 \ ! temperature
A4 ! salinity
AKT_BAK == 5.0d-5 5.0d-5 ! m2/s

ad_AKT_fac == 1.0d0 1.0d0 ! nondimensional
