Significant Hardware Upgrades to Wright-Weather.com This Week. Possible Interruptions

We are pleased to announce that we have made a major investment in new hardware and will be deploying a number of new Dell Enterprise Servers over the next several days.

These new servers will increase our computational processing capacity by 561% and our disk storage system will increase by over 600% .  Also,  our internal network backbone will increase by 10x.  We are also moving to a solid state storage array which will allow us to process data much faster than we have been able to in the past.

We are moving these new servers into a data center with some of the best peering and fastest internet connectivity available, which will result in a extremely responsive user experience for our customers.

As we make this transition off some of our older hardware to the new servers at the new location, there may be some temporary interruptions in some of the model data and other graphics for a brief time. We will be doing everything we can to prevent any delays in model production or interruptions to any of the products we generate.

As we get all the servers and systems fully migrated over  in the coming weeks, look for many more new and exciting products from Wright-Weather.com in the coming months.

If you have any questions or see any issues with the site, please do not hesitate to contact us at support at wright-weather.com

Hardware Upgrades for Our North Carolina Data Center

The GFS Model will be upgraded from ~27KM to ~13KM this summer. The High Resolution Rapid Refresh Model (HRRR) will become operational later this year.   Power Point Link (NCEP) 

In preparation for these and other expected increases in weather processing volume, we have been adding additional computing hardware to handle this data increase.  Using redundant Enterprise HP Proliant hardware in a 24/7 staffed SAS-70 Tier 1 Data Center, ensures we will be ready to handle the next generation of weather data. Below is an image of a few of the servers & equipment that deliver Wright-Weather.com products to you.

Added 925 Millibar Winds

Added 925 Mb winds to the NAM, NAM CONUS Nest & HWRF Models. They are in the drop down menus. Should be available with the 10-28-12 12Z runs.

Below is the forecast 925mb winds (just above the surface) as Sandy makes landfall. Winds of 95 knots are forecast  by the HWRF near Long Island. Mixing of these winds near surface by heavy rain showers will likely transport gust to 70 knots at times as the strong gradient north of the center rotates through.

 

GFS Atlantic 850mb vorticity added

The GFS 850mb vorticity was added this past weekend to the GFS Tropical menus. The 850mb vorticity can be a potential early indicator of tropical cyclone genesis.

The 850mb vorticity parameter has already been part of the ECMWF model guidance for a number of years.

FAA Terminal Doppler Radar’s Increased Update Frequency

Some of the FAA terminal Doppler radar products from a few of the locations will have up to 1 minute updates for the lowest elevation scans.  This rapid scan modes, known as “Hazardous Weather Mode” is triggered when a 30dbz echo is detected aloft within 25 miles of the radar site or if there is wind shear detected.  The following TDWR radar sites will begin to deliver 1 minute imagery when the radar is in “Hazardous Weather Mode”

TDAL       DALLAS LOVE FIELD (DAL)
TDFW       DALLAS/FT. WORTH (DFW)
TCLT       CHARLOTTE (CLT)
TCMH       COLUMBUS OH (CMH)
TCVG       COVINGTON (CVG)
TDAY       DAYTON (DAY)
TMDW       CHICAGO MIDWAY (MDW)
TORD       CHICAGO O’HARE (ORD)
TMKE       MILWAUKEE (MKE)
TEWR       NEWARK (EWR)
TJFK       NEW YORK CITY (JFK)

RUC (Rapid Update Cycle) Model Upgraded to the RAP (Rapid Refresh)

The RUC (Rapid Update Cycle) Model was upgraded today with the Rapid Refresh Model.  All of the links and graphics may still contain the acronym RUC but data is from the RAP model. The links and menus will be updated over the next few days to reflect the name change.

Here is a link to more information about the new Rapid Refresh Model.
