I have a question regarding the usage of SST values for simulating a real time event such as a tropical cyclone. I feel that I should use the most updated SST values in order to get the accurate intensity of my storm. But I also think that the updated SST can be cooler than the climatological ones and there are higher chances of convective inhibition within them. This also raises a question on coupled models as they are also used for operational forecasting.
Secondly, since the primitive equations corresponding to a regional weather model comprise an initial value problem I am unable to think of the extent to which the surface boundary conditions can effect the model solutions.
