Eddy diffusion in back trajectory?
Posted: December 16th, 2019, 2:03 am
There are two mechanisms in transporting water vapor in atmosphere, one is advection and one is eddy diffusion. I do not quite understand the numerical way HYSPLIT is modeling the back-trajectory, but it seems to me the most important are wind velocity and direction fields if I am right. If I modeled a back trajectory on a rainy hour, does the path only tell us the "advection" of air mass? Does the path also incorporate the eddy diffusion?
In addition, in tropical regions, precipitation is derived from convection. Is it appropriate to run back trajectory for convective rainfall hour to know where the water vapor is coming from?
