Graphics use 1° GFS Model Output


Terrain elevation in meters above sea level. Source: GFS0.25°(NOMADS-NOAA).

ALGORITHM GFS 00Z GFS 12Z
Trade Wind Inversion - TWIN.CMD
Detects the height of the Trade wind inversion's base in shaded colors, and the strength of the inversion using boxes. Larger boxes indicate a stronger inversion.

Potential for severity and hail - GR02T.CMD
GR02T highlights regions with the potential for severe weather using shades of color, and specifically, detects a potential for hail where colored boxes appear inside colored contours.
Idle
Idle
Enhanced GDI and Flow - EGDI.CMD
Very similar to the GDI, the Enhanced GDI (EGDI) diagnoses the potential for convection and rainfall accumulations. Loops include low- and upper-tropospheric flow and other variables to evaluate if atmospheric dynamics are favorable for triggering and/or sustaining convection.
Idle
Idle
Tropical/Easterly Wave Tracking - OTRP.CMD
850-600 hPa Mean Flow, 850-500 hPa mean Vorticity and enhanced GDI to track waves in the trades.
