Detailed Description

Combines multiple tasks together to make the HWRF post-processing system.

This is a wrapper around the hwrf.post, hwrf.gribtask, hwrf.tracker, hwrf.nhc_products and hwrf.gsipost that creates customizable post-processing tasks. The main purpose of this module is to simplify the hwrf_expt module.

Function Documentation

def hwrf.hwrfsystem.add_clatlon_grid	(		task,
			r,
			name,
			rel
	)

Add a domain-centered lat-lon grid to a RegribMany object.

Adds to the given hwrf.regrib.RegribMany object a latitude-longitude grid centered on some GRIB product. The grid will be re-centered at every forecast time, so the grid is allowed to move. Centering information comes from the name+"_grid" option in the task's section. The value should be a comma-separated list of seven values:

• res1,res2 - grid resolution for GRIB1 grid 255
• size1,size2 - size in degrees for GRIB1 grid 255
• scan - scanning mode flags for GRIB1 grid 255
• n1,n2 - gridpoint count for GRIB1 grid 255

  Parameters

  task	the task that provides configuration information
  r	the hwrf.regrib.RegribMany object to receive the grid
  name	the name of the new grid
  rel	the GRIB product in r on which this grid is centered

def hwrf.hwrfsystem.add_expandlatlon_grid	(		task,
			r,
			name,
			rel
	)

Adds a grid-centered lat-lon grid to a RegribMany object.

Adds a new grid to an hwrf.regrib.RegribMany object, centered on a prior existing grid but with a border added around its edges. The grid is recalculated at every forecast time so it works with moving grids as well. Grid expansion information comes from the name+"_expand" option in the given task's section. The value should be a comma-separated list of nine values:

• west extension in degrees
• east extension in degrees
• north extension in degrees
• south extension in degrees
• n1,n2 - new gridpoint count for GRIB1 grid 255
• scan - new scanning mode flags for GRIB1 grid 255
• res1,res2 - new resolution for GRB1 grid 255

  Parameters

  task	the task that provides configuration information
  r	the hwrf.regrib.RegribMany object to receive the grid
  name	the name of the new grid
  rel	the grid on which this grid is centered.

def hwrf.hwrfsystem.to_com_intercom	(		task,
			what,
			r
	)

Requests deliver to com and/or intercom of a RegribMany product.

Utility function for deliveries. Given what="hwrftrk" this will look for options "hwrftrk%com" and "hwrftrk%intercom" in the given task's config section. If each option is present and non-empty, the corresponding delivery is enabled and the option's value is used as the delivery location.

Parameters

task	the task that provides configuration information
what	the RegribMany product being delivered
r	the hwrf.regrib.RegribMany whose products are being delivered
