Sea surface temperature abnormal

#1 Unread post by xiaomeixu »

Hi all!
Here is a problem that I have been struggling with for quite a while.
The simulation results show that there will be a sudden increase in sea surface temperature at around noon (12-14 o'clock local time) every day. (Fig1 is the surface and bottom temperature at the same place (red is surface), fig2 is the surface temperatures at different places)

The atmospheric forcing file includes Uwind, Vwind, Pair, Tair, Qair, rain, swrad and lwrad every three hours.
In order to figure out this problem, I made some experiments:
① Using monthly averaged Tair to replace three-hourly Tair. There is still surface temperature abnormal.
② Using monthly averaged swrad to replace three-hourly sward. There is no surface temperature abnormal, but the total temperature decreases largely (fig3).
I have also attached my h file below.

Many thanks.
