Numerical Modeling

The motion of atmosphere/ocean is based on fluid dynamics which consist of several equations to describe the characteristics of flows in our real world. Numerical modeling allows us to understand how these flows evolve with time by solving equation sets with advanced computational abilities. Here demonstrates some numerical simulations of geophysical flows and codes are provide for those who are interested.

3-D cloud resolving model for DYNAMO (2020 Dec)

Check out on a Jupyter notebook.

Bickley jet

Barotropic instability is an instability growing from certain spatial distributions of vorticity in two-dimensional flow. a zonal jet, creating both positive and negative vorticity on its both sides, is fairly ideal for the development of barotropic instability.

Vortex merging

This simulation demonstrates the merging process between vortexes. In nature, similar phenomena can be observed when two tropical cyclones are close enough but showing more complexity in these dynamic processes.

Monopole vortex and waves

This experiment aims for simulating a monopole vortex that propagates to the west and bounces back as a Kelvin waves-like structure after hitting to the western boundary
