We have explained to climate researchers the RDC scheme, including both the basic mechanism and the application to numerical models. Unfortunately, there has been not yet positive action to implement the RDC scheme by active climate researchers. We guess the reason for this is that they have been looking at weather phenomena for so many years that they are too caught up in their intuition, and that they cannot break free from their dependence on the DD method that has been used for so long.

On the other hand, the number of density-stratified 3D fluid models in the CFD labs in the world is probably at least 100 times greater than the number of atmospheric models. If climate researchers are not willing to cooperate with us, we would like to join forces with CFD researchers.

We have experience in creating simple climatic atmosphere models (DCM and KCM, See References) with vertical 2D geometry that allow for long time integration in the energy balance of the Earth system. All physical processes in the atmosphere, such as radiative transfer, phase changes of water, heat supply from the surface, etc., were greatly simplified, which facilitated our understanding of atmospheric phenomena and allowed us to successfully extract the RDC mechanism.

Currently, we have neither a density-stratified 3D fluid model nor the computing environment to run it. However, once they are available, we are confident that we can build a 3D dynamical atmospheric model that can withstand long-time integration as well as our DCM. Perhaps the only essential thing required to convert a general 3D density stratified fluid model into an atmospheric model is the introduction of an anelastic system of equations to remove sound waves. The model will likely be a very simple 3D version of the DCM, which will make it easier to validate the RDC mechanism again and perform RDC cumulus parameterization in a real-time 3D atmosphere.

No matter how hard we try to publicize the RDC scheme, we do not have the initiative to advance RDC research. If the stalemate continues no matter how long we wait, we will have no choice but to build our own models. And instead of trying the RDC scheme on an existing complex atmospheric model, it may be faster to try the RDC scheme on a new real-time 3D atmospheric model that is as simple as DCM.

In addition, working with CFD researchers who are familiar with the boundary value problem, which is the main computational method of the RDC scheme, will be of great benefit when applying the RDC scheme after the model is completed.

Our alternative, of course, is to start from scratch with our own 3D dynamic model framework, which can be quite time-consuming and labor-intensive in our personal old and poor computing environment. If a density-stratified 3D fluid model is already available, the path to climate modeling can be greatly abbreviated.

We welcome CFD researchers who have no previous experience in global warming research but are interested in contributing to it. If you have the stable code for a density-stratified 3D fluid model which we can use, please contact us. While they are struggling with hopeless DD methods that violate the second law of thermodynamics, in a few years we will be able to show the world the effectiveness of the RDC scheme. We hope you will give it serious consideration. Thank you very much.
