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.

80 Meter Winds from the NAM & NAM CONUS WRF NEST Added

80 Meter winds above ground level from the NAM and also from the 4km NAM NEST have been added. This is very useful for our clients that are interested in forecasting for the all important hub height for wind turbines, at wind generation facilities.

These are updated 4 times per day.  If you have any questions please let us know.

WRF Model Compare Feature

We also recently added a WRF ARW/NMM comparison animation feature.  To view the side by side comparison of the WRF ARW/NMM model, select a WRF animation and below the animation there is a box called “WRF NMM/ARW Compare”. Select this and it will display the companion WRF model in the other screen for an easy comparison between the two models.
