Advection

Functions¶

`calc_u_advection`(→ xarray.DataArray)	Calculate zonal temperature advection at each vertical level.
`calc_v_advection`(→ xarray.DataArray)	Calculate meridional temperature advection at each vertical level.
`calc_p_advection`(→ xarray.DataArray)	Calculate vertical temperature transport at each vertical level.

easyclimate.core.advection.calc_u_advection(u_data: xarray.DataArray, temper_data: xarray.DataArray, lon_dim: str = 'lon', lat_dim: str = 'lat', min_dx: float = 1.0, edge_order: int = 2, R: float = 6371200.0) → xarray.DataArray¶

Calculate zonal temperature advection at each vertical level.

\[-u \frac{\partial T}{\partial x}\]

u_data: xarray.DataArray.: The zonal wind data.
temper_data: xarray.DataArray.: Air temperature.
lon_dim: str, default: lon.: Longitude coordinate dimension name. By default extracting is applied over the lon dimension.
lat_dim: str, default: lat.: Latitude coordinate dimension name. By default extracting is applied over the lat dimension.
min_dx: float, default: 1.0.: The minimum acceptable value of dx, below which parts will set nan to avoid large computational errors. The unit is m. You can set it to a negative value in order to remove this benefit.
edge_order: {1, 2}, optional: Gradient is calculated using N-th order accurate differences at the boundaries. Default: 1.
R: float, default: 6370000.: Radius of the Earth.

The zonal temperature advection. (xarray.DataArray).

easyclimate.core.advection.calc_v_advection(v_data: xarray.DataArray, temper_data: xarray.DataArray, lat_dim: str = 'lat', min_dy: float = 1.0, edge_order: int = 2, R: float = 6371200.0) → xarray.DataArray¶

Calculate meridional temperature advection at each vertical level.

\[-v \frac{\partial T}{\partial y}\]

v_data: xarray.DataArray.: The meridional wind data.
temper_data: xarray.DataArray.: Air temperature.
lat_dim: str, default: lat.: Latitude coordinate dimension name. By default extracting is applied over the lat dimension.

The meridional temperature advection. (xarray.DataArray).

easyclimate.core.advection.calc_p_advection(omega_data: xarray.DataArray, temper_data: xarray.DataArray, vertical_dim: str, vertical_dim_units: Literal['hPa', 'Pa', 'mbar']) → xarray.DataArray¶

Calculate vertical temperature transport at each vertical level.

\[-\omega \frac{\partial T}{\partial p}\]

omega: xarray.DataArray.: The vertical velocity data (\(\frac{\mathrm{d} p}{\mathrm{d} t}\)).
temper_data: xarray.DataArray.: Air temperature.
vertical_dim: str.: Vertical coordinate dimension name.
vertical_dim_units: str.: The unit corresponding to the vertical p-coordinate value. Optional values are hPa, Pa, mbar.

The vertical temperature transport. (xarray.DataArray).
