About Models National Hurricane Center Model Data (Plots from Tropical Atlantic) If you have the free program Google Earth, you can now view National Hurricane Center (NHC) model data using the plots our site generates. You can view either the "spaghetti" model plots or the full model plots. To access all model data in the Atlantic Basin, you can save either of the following files: Full Model Plots for the Atlantic Basin "Spaghetti" Model Plots for the Atlantic Basin These files will allow you to view the latest model data when it is available for active storms, including areas of investigation. If you would like to see an example of what the plots look like, click here to view a non updating example. In addition to having the model plots in Google Earth, model plots are also available using Google Maps when an active storm is available. Links to the Google Maps plots along with other ATCF storm data available through the NOAA ATCF database will be available through links that will appear at the top of every page on our site. Our active storm page can be found here. Colorado State's Model Data The Colorado state model site has a lot of models on 4 images that come out every 6 hours. To get the model imagery, under the header "Atlantic Basin," you will find the four products available. The newest data available will be under "frame 1" while the oldest under "frame 5." When there are multiple systems, frame 1 might be one system and frame 2 another system. At times, you might find that "frame 1" on one of the guidance images contains a different storm than "frame 1" on another guidance images. Just do a little searching. You may wonder why the time in the Early and Intensity images differ from those in the Late and GFS images. Click here for the reason why. The Colorado state updates at 4AM, 10AM, 4PM, and 10PM EDT (0200, 0800, 1400, and 2000 UTC) daily. Last season, it usually updated almost exactly at those times, though sometimes it does skip a run. South Florida Water Management District Model Data (SFWMD) The GFDL (Geophysical Fluid Dynamics Laboratory), BAMM (Beta and Advection Model, medium (850-400 hPa) vertically averaged winds), and BAMD (Beta and Advection Model, deep (850-200 hPa) vertically averaged winds) models are updated very soon after the information is available from the FTP servers: https://my.sfwmd.gov/sfwmd/common/images/weather/plots.html Click on an active invest area, tropical depression, or storm on that page. Ignore storm50 on that page. You will only see numbers, not names. storm90 through storm99 are invest areas. storm01, Alberto, is what it had for the first storm of the season was, Alberto. When it is no longer active it is removed from the page. These numbers are numbered in relation to the number of depressions that form in a season. For example, lets say that a tropical depression two forms but does not ever reach tropical storm status. You would access that by clicking storm02. When tropical depression three forms, if it becomes a tropical storm named Beryl, you will still access it through storm03, even though it is the second letter of the alphabet. In case you are wondering, this location: ftp://ftp.nhc.noaa.gov/pub/products/nhc/model/ Is where you can find text model data that goes into creating this image. Go to the very bottom of that long page. There are a few different files you may run into. The GFDL model comes out in its own file. The other model data comes out in another file. The latest of both files will be located at the bottom. Each comes out every 6 hours. Keep in mind that the times are in UTC time. (currently 4 hours ahead of EDT) Also note that the SHIPS intensity model is in knots. (multiply by 1.15 to get mph) You can open the file in a text editor. Sometimes it opens wrong. Try a different text editor then to open it. (Sometimes a file works in Notepad and not in Wordpad, and sometimes the other way around. But usually it always seems to open right in one of them.) Methaz.org Model Data (from the Kinetic Analysis Corporation and UCF) http://hurricane.methaz.org/tracking/ This is a great site. It's still going through some changes, so it may be out at times. Go to that main page and find the storm you are looking for on it. Click "Click here to start Interactive Mapping for ALXX2006, " where "XX" represents the storms number. Then you can just mess around with it. It has a lot of great features. Be sure to use the zoom to focus in on your area. Also on that front page you will find this (where STORMNAME represents the name of the storm): Reports based on KAC simulations of STORMNAME Current forecast model performance That's what I love. Which model is doing the best with the system? That's the best tool. I find it extremely useful. They used to have a lot of other data on it like airport, seaport, and oil production impact estimates. it also had county by county damage estimates. I can't find that data at the moment. Information on invest areas can be found at the bottom of the page. NWS Modeling of NHC Model Data The National Weather Service has a site that contains many of the models that the NHC has. The only problem is determining which model is which since you can't zoom in. http://www.srh.noaa.gov/srh/tropicalwx/forecasttrack.php Model Analyses and Forecasts from National Centers for Environmental Prediction (NCEP) Western North Atlantic (better for viewing the tropics) NAM (WRF-NMM, WRF - Weather Research and Forecast) (North American Mesoscale Model, info, main site: wrf-model.org), GFS (Global Forecast System, previously known as AVN), Global Ensemble (GEFS), WW3 (Wave Watch III), NGM (Nested Grid model) North America NAM (WRF-NMM, WRF - Weather Research and Forecast), GFS, Global Ensemble (GEFS), HRW (High Resolution Window WRF), NGM (Nested Grid Model), GHM (Which is actually the GFDL), Hurricane WRF (HWRF, about), SREF (Short-Range Ensemble Forecast, about), RUC (Rapid Update Cycle, about), and Real-Time Mesoscale Analysis (RTMA) Product Description Document for NCEP's Model Analyses & Forecasts This is the document that will let you know what the models are at NCEP. An older document about the GFS, WW3, NGM, and RUC: http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/PDDwebsite_200403.txt Another site with imagery from NAM: http://www.emc.ncep.noaa.gov/mmb/mmbpll/etaop/ NCEP/EMC Cyclogenesis Tracking Page: http://www.emc.ncep.noaa.gov/gmb/tpm/emchurr/tcgen/ Models projected path of low pressure areas all on one image. This is an interesting page you should check out. Once on the site, click the latest time in the left frame. From that you'll see a page full of different regions and models. If you are looking for a storm that diesn't happen to be near North America, such as in the Caribbean or across the Atlantic basin, scroll down the page and there is a table for the Atlantic basin. There are a variety of models to choose from, such as a multi-model, GFS, NAM, NCEP Ensemble, SREF Ensemble, Ukmet (UK Meteorological), and NOGAPS (Navy Operational Global Atmospheric Prediction System). The images show the path of a low with a line and also display the pressure, which is quite helpful. You might also want to see this page for some very advanced information: http://www.emc.ncep.noaa.gov/gmb/ens/ It links to the NCEP/EMC Cyclogenesis Tracking Page above, but unlike that site, the other sites are very advanced. This site on that page might be worth checking out: http://www.emc.ncep.noaa.gov/projects/wd21hc/ensemb/web/html/us_prob.html It contains, on a global image, the probability (along with a few other options) that a certain threshold will be attained for a certain parameter. The parameters are wind speed, significant wave height, and peak wave period. It can be run as a loop out to about 5 days. Note, when you change some of the text fields, give the image a bit of time to update. (There is no button to press, it just takes a short time to update) NCEP CFS (Climate Forecast System, Coupled Forecast System) Forecasts: http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/lanina/ensoforecast.shtml About CFS: http://cfs.ncep.noaa.gov/ The forecast page, updated daily, "provides seasonal climate anomalies from the NCEP coupled forecast system model (CFS03). One forecast run is produced each day for 9 target months." It doesn't contain information that is valid for any current storm. You can view such things as the SST anomalies expected or the global SST's to determine such things as El Nino in the future. More info about some of the above models from NCEP can be found here: Environmental Modeling Center Model Documentation Canadian Model From the Meteorological Service of Canada, Environment Canada... Canadian Meteorological Centre's (CMC) Global Environmental Multiscale (GEM) model Weather Charts Ensemble Forecasts About Canada's models Operational Analysis Charts and Bulletins (Current Surface/Upper Air Analysis) From the Atmospheric Sciences Group at the University of Quebec at Montreal... CMC GEM forecast models What is nice about this site is that it goes out to 240 hours for the 0Z run for North America. More Model Data... Weather Underground: http://www.wunderground.com/tropical/ On that big page, under "North Atlantic Storm Advisories," you will see the latest storms. Click "Computer Models." The image on that page is derived from the NHC model data that the SFWMD uses too. However, this image does not update as fast as SFWMD. I include this link because unlike the SFWMD image, this one includes the SHIPS intensity model data. (calculated to mph) If you don't want to look on the FTP server at the NHC for that data, you can easily see it here when it updates. From the NAVY's Fleet Numerical Meteorology and Oceanography Center: GFS NOGAPS CMC, GFDL, GFS, HWRF, MM5, NOGAPS, UKMET http://moe.met.fsu.edu/tcgengifs/ This site runs somewhat behind the other model sites, though it is nice to look at their imagery over other sites that have the information. Cyclone phase evolution: Analyses & Forecasts http://moe.met.fsu.edu/cyclonephase/ This goes more in depth on the path. It shows you the line where the center is expected to travel along with some pressure and other data expected at the core. It too is not as up to date as the previously mentioned sites. European Centre for Medium-Range Weather Forecasts: ECMWF - North America NOAA's Air Resources Laboratory (ARL): Forecast Model Animations - NAM, RUC, AFWA MM5, GFS, GFS Long-Range MM5 (Fifth-Generation NCAR / Penn State Mesoscale Model, about) Tropical Cyclone Prediction: http://moe.met.fsu.edu/mm5/ Tropical Cyclone model page from PSU http://tc.met.psu.edu/ - GFS, CMC, NOGAPS, GFDL, WRF Models at Unisys NGM Model NAM/Wrf Model GFS/Avn Model GFSx/MRF Model RUC Model ECMWF Model Ohio State University's model page: Numerical Model Output - MM5, NAM, NGM, GFS, UKMET, MRF (Medium Range Forecast Model), ECMWF, RUC Weather Underground Models Weather Underground has a nice display of the GFS and NAM models with a variety of different options that you can choose. They also have the latest GFDL run with several different maps to select from. e-WALL: Pennsylvania State University (PSU) Electronic Map Wall Lots and lots of models and other tropical information, including satellite imagery. This site is really great. Try not to get overwhelmed by all the information. Jump right to: Tropical Atlantic e-WALL Notice in the left column the satellite views, including floaters, available.
