  1. Put your weather links in this thread. That way, as we add new people to this region, they have places to go and learn. Plus, it gives us all a quick reference. As a general rule, most of us abide by "read more and post less." However, for this forum to work...people have to participate. When making a comment, just be sure to add some weather expertise to your discussion(even if it is limited). Instead of saying, "Boy, it is raining outside." Try this, "The National Weather Service radar is showing heavy returns over middle Tennessee." Instead of saying, "The weather models are showing a torch," try this..."The GFS is showing warm temps at hour n." Read as much as you can. Google is a great tool. And don't be afraid to ask questions. That's how all of us learned to get to our varying levels of expertise. Last update: November 2018

    GFS-view

    Hi there! Please, look at this small freware tool to download and display 0.25 degree maps from the NCEP NOMADS servers. https://sourceforge.net/projects/gfs-view/ Feedback is wellcome
  3. Hi Everyone, I have been working on a tool to allow global point extractions from various models. Right now the page allows you to pull surface variables from the following models, GFS,GEM,NAM and the GFS and CMC ensemble means globally. The page pulls the points you request not predefined cities or airports. I would like to get some feedback so please check out the page. The page URL is http://weather-globe.com. Let me know what you think!
  4. hi; Amateur here; I am looking at the 384 hour GFS forecast. What is the accuracy of any forecast that goes past 84 hours? Currently I am looking only at what data is available free, using tools like f5, Wundamaps, and U of WY (U of WY has GFS only to 10 days). FW edit: never mind - I posted the question to an existing thread.
  5. The title and link say it all: http://www.noaanews.noaa.gov/stories2015/20150105_supercomputer.html?utm_content=buffer1a56f&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer (Pasted content, from NOAA) Today, NOAA announced the next phase in the agency’s efforts to increase supercomputing capacity to provide more timely, accurate, reliable, and detailed forecasts. By October 2015, the capacity of each of NOAA’s two operational supercomputers will jump to 2.5 petaflops, for a total of 5 petaflops – a nearly tenfold increase from the current capacity. “NOAA is America’s environmental intelligence agency; we provide the information, data, and services communities need to become resilient to significant and severe weather, water, and climate events,” said Kathryn Sullivan, Ph.D., NOAA’s Administrator. “These supercomputing upgrades will significantly improve our ability to translate data into actionable information, which in turn will lead to more timely, accurate, and reliable forecasts.” Ahead of this upgrade, each of the two operational supercomputers will first more than triple their current capacity later this month (to at least 0.776 petaflops for a total capacity of 1.552 petaflops). With this larger capacity, NOAA’s National Weather Servicein January will begin running an upgraded version of the Global Forecast System (GFS) with greater resolution that extends further out in time – the new GFS will increase resolution from 27km to 13km out to 10 days and 55km to 33km for 11 to 16 days. In addition, the Global Ensemble Forecast System (GEFS) will be upgraded by increasing the number of vertical levels from 42 to 64 and increasing the horizontal resolution from 55km to 27km out to eight days and 70km to 33km from days nine to 16. Computing capacity upgrades scheduled for this month and later this year are part of ongoing computing and modeling upgrades that began in July 2013. NOAA’s National Weather Service has upgraded existing models – such as the Hurricane Weather Research and Forecasting model, which did exceptionally well this hurricane season, including for Hurricane Arthur which struck North Carolina. And NOAA’s National Weather Service has operationalized the widely acclaimed High-Resolution Rapid Refresh model, which delivers 15-hour numerical forecasts every hour of the day. “We continue to make significant, critical investments in our supercomputers and observational platforms,” saidLouis Uccellini, Ph.D., director, NOAA’s National Weather Service. “By increasing our overall capacity, we’ll be able to process quadrillions of calculations per second that all feed into our forecasts and predictions. This boost in processing power is essential as we work to improve our numerical prediction models for more accurate and consistent forecasts required to build a Weather Ready Nation.” The increase in supercomputing capacity comes via a $44.5 million investment using NOAA's operational high performance computing contract with IBM, $25 million of which was provided through the Disaster Relief Appropriations Act of 2013 related to the consequences of Hurricane Sandy. Cray Inc., headquartered in Seattle, plans to serve as a subcontractor for IBM to provide the new systems to NOAA. “We are excited to provide NOAA’s National Weather Service with advanced supercomputing capabilities for running operational weather forecasts with greater detail and precision,” said Peter Ungaro, president and CEO of Cray. “This investment to increase their supercomputing capacity will allow the National Weather Service to both augment current capabilities and run more advanced models. We are honored these forecasts will be prepared using Cray supercomputers.” "As a valued provider to NOAA since 2000, IBM is proud to continue helping NOAA achieve its vital mission," said Anne Altman, General Manager, IBM Federal. "These capabilities enable NOAA experts and researchers to make forecasts that help inform and protect citizens. We are pleased to partner in NOAA's ongoing transformation." NOAA's mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources.

  6. I would like to know where I can find an archive of GFS Extended Range MOS where I can simply type in the station ID ("KITH") and select a certain date and time.
  7. I would like to create the ultimate free online weather visualization tool. Specifics are below. If you have any questions, do not hesitate to ask. Dimensions Time Start: 1000 AD January 1, midnight End: 10 years from current time Resolution: Every second Latitude Start: 90S End 90N resolution 0.00001 degrees. Longitude Start 180E End 180W resolution 0.00001 degrees Height: Start 1000 m below sea level End 10,000,000 m above sea level Resolution: 0.1 meter. Some heights will be in the ground, but we will use thermodynamic equations and lapse rates for this.
