extreme value of precipitation over tropic – in #8: General Questions

in #8: General Questions

<p> Hello Bo, <br/> most probably the high values of precipitation at individual grid points originate in the numerics of advection which cannot deal with convection at individual grid points. <br/> Instead of cooling feedback at the surface it is enhancing the convection. </p> <p> In cosmo_4.8_clm19 there is still this problem. <br/> This has been fixed in a more recent version by Uli Blahak and will be available with 5.0. <br/> I would appreciate if you could implement this modification of advection in 4.8_clm19 and test it. <br/> Please contact me in the case, you would like to do that. </p> <p> Greetings, Andreas </p>

Hello Bo,

Instead of cooling feedback at the surface it is enhancing the convection.

In cosmo_4.8_clm19 there is still this problem.
This has been fixed in a more recent version by Uli Blahak and will be available with 5.0.
I would appreciate if you could implement this modification of advection in 4.8_clm19 and test it.
Please contact me in the case, you would like to do that.

Greetings, Andreas
