xoa.dyn.flow2d

xoa.dyn.flow2d(u, v, xy0, duration, step, date=None)

Integrate gridded 2D velocities from random positions

Parameters:

• u (xarray.DataArray) – Gridded zonal velocity

• v (xarray.DataArray) – Gridded meridional velocity

• duration (int, numpy.timedelta64) – Total integration time in seconds

• step (int, numpy.timedelta64) – Integratiin step in seconds

• xy0 (int, xarray.Dataset, tuple) – Either a number of particles or a dataset of initial positions with longitude and latitude coordinates

• date (None, numpy.datetime64) – A reference date for the time integration

Returns:

xarray.Dataset – Output positions with lon and lat coordinates that vary with time.
