CIMSS Envrionmental Steering product<\/p><\/div>\n

Jason Dunion (formerly at CIMSS, now at the NOAA\/AOML Hurricane Research Division)<\/em> penned an excellent summary of the utility of the CIMSS Environmental Steering<\/strong><\/a> (or Deep Layer Mean Wind<\/strong><\/a>) product that is available on the CIMSS Tropical Cyclones<\/strong><\/a> site. Satellite-derived Atmospheric Motion Vectors produced at CIMSS are in important inputs to these environmental steering flow products. With Hurricane Gustav, Tropical Storm Hanna, Hurricane Ike, and Tropical Storm Josephine<\/em> all in the Atlantic basin, Jason noted the following interactions between the steering flow patterns and the motion of those 4 tropical cyclones during the first few days of September 2008:<\/p>\n

03 September:<\/strong>
\n– Gustav<\/em> has made landfall and helps build ridge #1 to its east
\n– big ridge #2 is located north-northeast of Ike<\/p>\n

04 September:<\/strong>
\n– gigantic low over Canadian Maritimes lifts out;
\n– ridge #1 slides to the east, ridge #2 slides to the west<\/p>\n

Late 04 September to early 05 September:<\/strong>
\n– ridge #1 & ridge #2 link to form a sprawling ridge to the north of Ike<\/em>
\n– Ike<\/em> is stuck in northwesterly steering flow until that “ridge linking”, and then starts a turn to the west<\/p>\n

05 September:<\/strong>
\n– ridge #1 and ridge #2 consolidates and parks to the north-northwest of Ike; Ike<\/em> then quickly comes into a southwesterly steering flow
\n– Hanna<\/em> is forced “up the alley” between ridge #1\/#2 and a trough approaching from the west
\n– Josephine<\/em> is pushed to the northwest by the deep flow (shallow Deep Layer Mean is more of a west-southwesterly flow); Josephine<\/em> then deteriorates as southwesterly\u00c2\u00a0 wind shear increases<\/p><\/blockquote>\n
