Detailed Description

This module contains the track delivery function and all dbn alerts in the HWRF system.

It is intended to sit on top of the ush/hwrf_expt.py as the NCO alert and NHC data delivery module. Generally the functions in this module are run by the scripts/ex*.py programs just before handing control over to the hwrf_expt package.

Classes
class	TrackDeliveryFailed
	Raised when the send_nhc_track() is unable to deliver the track file. More...

Functions

Function Documentation

def hwrf_alerts.add_nhc_alerts

(

)

Adds dbn alerts for the hwrf_nhc_products program's output by adding DBNAlert objects to the hwrf_expt.nhcp object's Products.

def hwrf_alerts.add_regrib_alerts

(

)

Adds dbn alerts for GRIB products by adding DBNAlert objects to the hwrf_expt.gribber.

Adds calls to the dbnet alerts so that GRIB files will be delivered to the NCEP FTP server.

Adds dbn alerts for the tracker and requests delivery of the tracker to NHC deck locations.

def hwrf_alerts.add_wave_alerts

(

)

DBN ALERTS #########################################################.

Adds dbn alerts for the WRF program's wrfdiag files, which are used by the downstream wave model.

Ensures the wrfdiag files have the necessary dbn_alerts to trigger delivery to the NCEP FTP server and ecFlow events (if required). Those files will be delivered by the NHCProducts object at the end of the JHWRF_PRODUCTS job, after the hwrf_nhc_products program completes. We run the hwrf_nhc_products program before delivering the wrfdiag files to ensure that the files are plausable before delivering them to the wave model.

def hwrf_alerts.email_afos_to_sdm	(		afos,
			args,
			kwargs
	)

Emails the AFOS file to the NOAA Senior Duty Meterologist (SDM)

This function is called from scripts.exhwrf_output to email the AFOS file (simplified track file) to the Senior Duty Meteorologist (NOAA SDM). It is controlled by a number of environment variables, requested by NCEP Central Operations:

• EMAIL_SDM=YES/NO — turn on or off the email
• HWRF_TRACK_EMAIL_LIST=(list of emails) — list of email addresses to receive the AFOS file.
• HWRF_EMAIL_SSH_MACHINE — no longer used. This was the machine to ssh into, to send the mail. The mail is now sent directly from the machine running the exhwrf_output script.

The following configuration settings have the same meaning as the environment variables:

• [config] email_sdm = $EMAIL_SDM
• [config] track_email_list = $HWRF_TRACK_EMAIL_LIST
• [config] email_ssh_machine = $HWRF_EMAIL_SSH_MACHINE

In all cases, the environment variables override the config file settings (again, by request of NCO).

def hwrf_alerts.send_nhc_track	(		args,
			kwargs
	)

Sends the track file to special NHC disk locations on the WCOSS supercomputer.

Parameters

args,kwargs

Ignored.

Note

This does not sort the track file, and does not grep out the correct storm, since that is already done before this function starts.
