Dear colleagues,

We would like to draw your attention to the ocean sciences 2024
session: PS006 - Modeling the ocean/atmosphere using Lagrangian
vertical coordinates and their applications in scientific research:
past and future. In this session, we welcome abstracts which use
models with isopycnal coordinate for the ocean or isentropic
coordinate for the atmosphere or hybrid vertical coordinate to advance
our understanding of the weather and climate dynamics and variability
on different timescales. The deadline to submit your abstract is Sept.
13, 2023. For more session details, please see below.

Thanks!

Aixue, Eric, Bob and Shan

Two types of vertical coordinates have been used in modeling the
atmosphere and ocean: vertically Lagrangian (sometimes called layered)
vs. vertically Eulerian (sometimes called level). For the former,
layers can move up and down vertically with time (Lagrangian) but
levels are fixed in space and time for the latter (Eulerian). Although
both types of models share the same set of equations, different parts
of the ocean or atmosphere can be better represented by a layered
model than level model. For example, away from boundaries, the flow of
ocean and atmosphere is along the isopycnic/isentropic surfaces. For
the vertical velocity, it is determined by the continuity equation in
both types of models. The difference is that this vertical velocity is
prognostically determined in layered models, but diagnostically
determined in level models. Over the last 30 years, significant
improvements have been made for the layered modeling which makes this
type of models suitable for a wide range of applications from weather
forecasting to climate change research and regional oceanography. In
this session, we welcome abstracts using layered models of the ocean
or atmosphere to advance our understanding of the Earth weather and
climate system.
