Introduction

For those granted time on Jet for HFIP real-time model experiments for this hurricane season, you are invited to show your model output on the HFIP products pages, hfip.org/products.

 

With your assistance, we will generate HFIP graphics for a quasi real-time display of experi- mental forecast guidance from various organizations into one centralized location. Scripts post- process model grids to create graphical files via predefined criteria. This allows comparison using common criteria: graphical display of products, particular colors, set map projections and scale, time matching. All in one place, alongside operational model output displayed in the same manner.

There are two requests for data.

  1. Experimental graphical model output, described here.
  2. Experimental storm ATCF track output for display on   ruc.noaa.gov/tracks/  described at the end of the document.

Code information

The graphical software was originated for the 2012 hurricane season. It has been continually used and supported. Origins of the graphical scripts: GrADS graphics visualization scripts create the graphics; they were written by David A Zelinsky, NHC; and the images were vetted by the NWS NHC forecaster.

Product Descriptions

Hfip.org show and describes the products. hfip.org/products/about.html#DeterministicProducts

Graphics are generated for both the Regional Scale domain (the parent domain) and, when applicable, the Storm Scale domain (the nest domain). These graphics are created using the GrADS visualization tool.

· Mean Sea Level Pressure (4 and 2 mb contours)

· 10 m wind

· 1000-850 mb thickness

·  850 mb wind, 850 mb height, 850 mb vorticity

·  700 mb relative humidity, 700 mb wind, 700 mb height, 700 mb vorticity

·  500 mb height, 500 mb wind, 500 mb vorticity

·  200 mb wind, 200 mb height

·  A combined graphic with 850 vorticity, 500 height, 200 wind

The variables listed above are consolidated into six specific images for each scale in the following configuration, as vetted originally by the NHC forecasters. The example images below are from the operational HWRF 2017, for TC Maria on 2017091800.

Tracks

Experimental storm ATCF track output from experimental models are included for display on ruc.noaa.gov/tracks/. Create ATCF data with a post-process of the model output. Let us know where your files are located on jet. That’s it.
