Board » Technical Discussion » January 2015 weather update problems

Page: Previous 1 2

I started to wonder bit how reliable the weather update process in the server has been. This data is from the new server, starting from September 2013.

I must say that the process has been much stabler than I actually thought, overall in 1.5 years we have missed only 4 weather updates completely.

The times in these statistics are the time when the weather file loading to the server has finished. After that it takes 2-3 minutes to be modified to suit the race areas. So the times shown in the client as the weather timestamp are in average few minutes later than these times.

So if the average time the 04:30 update has arrived to the server is 04:25 then the average time it has been available for clients is perhaps 04:28.

Viva Markku,

It is a lot easier to criticize than do it.
Doing well as this is the case is simply demonstrated by an impeccable record.
Hats off to the WF SOL team.

PROBLEMA MODELLI: Avviso agli utenti.

Nell'ultima settimana abbiamo avuto diversi problemi con i modelli: sono saltate alcune "corse" inficiando molti servizi, tra cui le mappe vento&mare.
Il problema è dovuto alla quasi saturazione della banda internet dell'NCEP (National Center Environmental Prediction della NOAA), causato da una sempre maggiore richiesta di dati dai vari centri del mondo e sopratutto dal recente aumento di risoluzione del modello globale GFS passato da circa 30 km a circa 13 km di risoluzione. Infatti i file disseminati seppur ad una risoluzione minore (di circa 25 km) pesano circa 4 volte di più dei precedenti (circa 300 MB a file).
Nella segnalazione allegata la NOAA rassicura sul fatto che sono a conoscenza del problema e stanno studiando una soluzione, tra cui un aumento di banda disponibile, previsto per Aprile - Giugno. Fino ad allora faremo del nostro meglio per continuare a garantire il servizio senza interruzioni, scusandoci sin da ora per gli inconvenienti causati e futuri.

"NCEP Central Operations systems -- the NCEP FTP Server (“ftpprd”) , NOMADS and MAG systems, and the recently-implemented MADIS and MRMS applications, are being affected by an Internet capacity issue at the NOAA Network Operations Center. The manifestation of this issue is slow data retrieval from these services. The root cause of the issue is that these dissemination systems utilize the NOAA Internet link and that link has reached saturation, especially at those times of the day when the major models are being disseminated. The slowness has been exacerbated by the recent GFS model upgrade, which gave users access to the new high-resolution dataset and also some of the existing output files increased in size dramatically with the model resolution increase.

The plan to address this Internet capacity issue is for the NOAA NOC to increase the capacity of the NOAA Internet link. This activity is currently in the procurement phase, with an FY15Q3 (April – June) implementation goal. NCEP is working closely with the NOAA NOC to track the progress of this upgrade. In the interim, NCEP is investigating some stop-gap measures that could provide some very limited relief.

We apologize for the impact this has had on our customers. We recognize that the ability to retrieve our products in a timely fashion is very important to our users and I assure you we are working to address the situation.

Becky Alwyn Cosgrove
Chief, NCEP Central Operations, Production Management Branch"

Sinbad by Balloon 2025 - Baia de l'Oiseau to Carnarvon


How ever shall I return to report with clear report to the Sultan – asked Sinbad. It must be told this island and all its fables shall be expunged from the annals of every thousand and one night. The wind howls here, and sun be none (it’s Winter, Sin, ed.) and all days from the west, but let’s launch anyway and see if we can work our SOL Balloon north as the days pass aiming for Asthralaya, where The Mahabharata tells the ancients once tested mighty weapons, about a quarter and a million qasbah away (2500nm, ed.), perhaps one month.

Nantucket Sprint 2025


Welcome to Nantucket, from whence Herman Melville’s Cap’n Ahab sailed round The Horn into the northern Pacific Ocean to hunt the gray whale - whose migrations are celebrated elsewhere in SOL’s Q4 schedule - he never to return. And whaling too, as the 19th C progressed, like Ahab disappeared from Nantucket as the harbour silted up and mainland Massachusetts whaling stations benefited from rail connections. But beach life, yachting and nostalgia has rescued the island from oblivion, so to celebrate leisure, SOL gives you the Nantucket Sprint - 25nm in 29er_XX’s from Great Point to Muskeget & Tuckernuck Islands across the sound to a finish just inside the mouth of the harbour. Enjoy!
