Here is today's summary of NHC computer operations:
--- Craig Mattocks
1. The early Wind Speed Probabilities for TS Otto did not arrive in AWIPS.
TSB Chief Mark DeMaria verified that the early WSP ran successfully on
WCOSS, with output in the /com/nhc/para directory. TSB is investigating why
the script that transfers the data failed.
2. TS Otto's name could not be moved on the Pacific Danger Graphic. There
is an area between 80W and 100W that appears on both graphics. TSB
Developer Matt Sardi is investigating to find a solution.
3. NCO Windows SysAdmin Kim Gordon was able to clear a large PowerPoint
document from the print queue on the TAFB HP color laser printer. This old
printer has a very small amount of RAM memory (128 MB). Rather than
spending money to add more RAM, NHC may want to consider purchasing a new
color printer to replace it.
4. Update on TAFB forecasters' back up of CPHC yesterday, when connections
for all Alaska and Pacific Region forecast offices went down on the AWIPS
WAN (wide area network) during network maintenance. Communications were
restored at 17:33 UTC (12:33 pm EST) and Honolulu assumed responsibility a
few minutes later.
1. The NRL Tropical Cyclone web page became inaccessible after about 02 UTC
(9 pm EST), at about the same time a 30-minute failure occurred in the NAVO
(Naval Oceanographic Office) network circuit. Around the same time, the
FNMOC TC web page that had been down for several days was updated with new
2. Senior Hurricane Specialist Mike Brennan received a call from the TOC
(Telecommunication Operations Center) in Silver Spring, MD at 5:35 am EST,
saying they detected an alert that the TCMAT1 (Atlantic forecast
advisory) "was sent but not received within 30 minutes". Mike told them
that the TCM made it to NHC's AWIPS system and website without any
problems. The TOC wasn't sure why they received this false alarm on their
1. The network outage yesterday, when both of NHC's Century Link internet
circuits went down, was caused by an upgrade to one of the lines. The
network was supposed to automatically fail-over to the secondary line but
that did not work properly. Once the circuits were rerouted through
Orlando, communications were restored. This issue has been resolved so this
should not happen the next time a circuit is upgraded. The outage was not
related to the new Hurricane Hotline test.
2. NCO is tentatively planning a WCOSS production switch from the Orlando,
FL (Gyre + Surge) supercomputers to the Reston, VA (Tide + Luna)
supercomputers on December 1st.
1. Output from the upgraded ECMWF model has started flowing to NCEP today
beginning with the 06 UTC cycle. For details on the upgrade, see:
The IFS Cycle 43r1 upgrade includes changes in data assimilation (both in
the EDA and the 4DVAR), new cloud and freezing diagnostics, a new
direct-beam solar radiation diagnostic and new significant wave height
parameters at different period ranges to help with the detection of
low-frequency ocean wave energy. There is also a major upgrade to the
dynamical ocean model (NEMO) - the resolution has increased to 0.25 degrees
and 75 layers, plus an interactive sea-ice model (LIM2) has been
