weatherbench2.derived_variables.IntegratedWaterTransport

class weatherbench2.derived_variables.IntegratedWaterTransport(u_name='u_component_of_wind', v_name='v_component_of_wind', water_species_name='specific_humidity', level_min=300, level_max=1000)

Compute integrated horizontal water transport in a vertical column.

Integrated vapor transport (IVT) is a useful diagnostic to include for understanding atmospheric rviers. Default pressure levels to include are taken from the GraphCast paper.

Parameters:

• u_name (str) –

• v_name (str) –

• water_species_name (str) –

• level_min (Optional[float]) –

• level_max (Optional[float]) –

u_name

Name of wind U component.

Type:

str

v_name

Name of wind V component.

Type:

str

water_species_name

Name of water species to vertically integrate.

Type:

str

level_min

Minimum pressure level to include.

Type:

Optional[float]

level_max

Maximum pressure level to include.

Type:

Optional[float]

__init__(u_name='u_component_of_wind', v_name='v_component_of_wind', water_species_name='specific_humidity', level_min=300, level_max=1000)

Parameters:

• u_name (str) –

• v_name (str) –

• water_species_name (str) –

• level_min (Optional[float]) –

• level_max (Optional[float]) –

Return type:

None
