INPUT DATA REQUIREMENTS FOR LAG RANG IAN TRAJECTORYMODELS

摘要

The Lagrangian approach to fluid motion follows a fluid parcel as it moves with the flow. Lagrangian methods have proven to be very useful for understanding the properties of atmospheric flows, particularly for problems related to transport, dispersion, and mixing of trace constituents or other atmospheric properties. In particular, Lagrangian methods can be used to identify pathways for atmospherictransport by computing the trajectories of air parcels as they move in the atmosphere.
