pvtend.EventPatch

class pvtend.EventPatch(grid: NHGrid, lat_half: float = 21.0, lon_half: float = 36.0)[source]

Event-centred patch extraction from a full NH grid.

grid

The underlying NHGrid.

lat_half

Half-window in latitude [deg].

lon_half

Half-window in longitude [deg].

__init__(grid: NHGrid, lat_half: float = 21.0, lon_half: float = 36.0) → None

Methods

`__init__`(grid[, lat_half, lon_half])
`extract`(data, ilat, ilon[, eff_north, eff_south])	Extract event-centred patch from (..., nlat, nlon) data.
`nearest_idx`(lat0, lon0)	Find nearest grid index and check if patch fits.
`relative_grid`()	Return relative coordinate arrays (Y_rel, X_rel) in degrees.
`wrapped_lon_index`(ilon)	Return longitude indices with periodic wrapping.

Attributes

`lat_half`
`lat_pad`	Number of grid points of padding in latitude.
`lon_half`
`lon_pad`	Number of grid points of padding in longitude.
`patch_shape`	Shape of the extracted patch (nlat_patch, nlon_patch).
