It is that time of year again! The time of year where tropical storms, hurricanes initiate and permeate through the Atlantic and the East Pacific Oceans. Currently, a few to note are tropical depression Greg, Tropical Storm Irwin and Hurricane Hilary. A screenshot of the National Hurricane Center’s  (NHC) ‘Active Storm’ Map showing the relative Continue Reading

Transverse bands were observed between approximately 1400-1700 UTC in the vicinity of Buffalo, NY in the GOES water vapor imagery (from the CIMSS satellite blog): http://cimss.ssec.wisc.edu/goes/blog/wp-content/uploads/2013/02/130208_g13_wv_east_coast_storm_anim.gif and also in the GOES IR imagery: http://rammb.cira.colostate.edu/templates/loop_directory.asp?data_folder=training/visit/loops/8feb13_BUF_ir&image_width=1020&image_height=900 Note the orientation of the transverse bands is approximately perpendicular to the winds at upper levels (350 mb wind direction and Continue Reading

Jeff Braun Below are some links to, or copies of, some perhaps lesser known meteorological training materials.  Many of these have been born out of Aviation Weather programs either here in the USA through the military Air Force Weather Agency (AFWA) or the FAA, or from up north and our Canadian Neighbors.  Although some of Continue Reading

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

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
