I am using a mesoscale model to simulate a tropical cyclone. The model input file has an option of 'Frequency of Radiation Tendencies update time' for Longwave and Shortwave radiation. According to me, all the parametrization schemes are updated at every time step,then why is it mentioned separately and how will it work? My question might be vary basic but instead of having the codes, I am unable to visualize what is happening with the radiation parametrization in my model. Is there any tutorial where I can get its clear description?
I am also searching for a tutorial for TC simulation where the basic steps to simulate a TC are given for beginners. It will be of great help if I can get it here.
