QPF Bombs and Getting the Most Out of Your Model

J. Braun Above is an example of two model forecast runs (12 hours apart).  The main difference comes when looking at the QPF amounts generated over ERN ND and NWRN MN between the two model runs.  The later model run on the right is able to transport more moisture to the north as opposed to the earlier run with the large QPF Bomb over ERN KS and Continue Reading

NWP Models (NCEP) Problems in Forecasting

Hawaii, Up Close and Personal

Jeff Braun Look at the following three images from the TERRA (EOS AM-1) satellite and the plotted image from the QuickSCAT satellite (courtesy NASA TERRA project – http://terra.nasa.gov/) and try to determine: 1. What is going on around the Big Island (first photo – top)? 2. Which side of the islands tend to get more precipitation Continue Reading

Central CONUS River Flooding – from CIMSS

This is some great stuff from the CIMSS bunch at the University of Wisconsin.  Read the following message sent March 21, 2008 and click the accompanying link to go to their satellite blog.     “MODIS images showing the extent of river flooding in the central US have been posted on our CIMSS Satellite Blog:      http://cimss.ssec.wisc.edu/goes/blog/archives/628 Continue Reading

Highlights from the Dec. 11-12, 2007 “Review of the NCEP Production Suite” Conference

J. Braun Not to diminish the importance of the entire two day conference, this is just a “good parts,” slightly abridged review and link(s) to information concerning the NWP models from NCEP that we can use. “Progress on Future NCEP Production Suite:” – presented by Steve Lord, the director of the Environmental Modeling Center (EMC), diagrams Continue Reading

What Is Going On Here?

J. Braun Click here http://rammb.cira.colostate.edu/visit/AniS/02261998/Vis_Loop1.html to go to a loop of a group of images from one of our GOES satellites (full disk). The loop is composed of an “enhanced” set of visible images so that dark (near black) stands out as speckled red/blue. As you animate the loop, notice the two fast moving “patches” Continue Reading

The Front: The Importance of Climatology in Aviation

J. Braun In the latest issue of “The Front” – the National Weather Service’s aviation forecast news e-magazine – an article titled, “The Importance of Climatology in Aviation” shows us why climatology is important not only to the aviation forecaster, but to prospective pilots too. Click here: http://aviationweather.gov/general/pubs/front/docs/dec-07.pdf for the latest December, 2007 issue.  Also in Continue Reading
