TROPICAL DEPRESSION KILO DISCUSSION NUMBER 6
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI CP032015
500 PM HST FRI AUG 21 2015

SATELLITE IMAGES THROUGH THE DAY SHOWED THAT THE ORGANIZATION OF
KILO HAS CONTINUED TO DETERIORATE. AN EXPOSED…ELONGATED LOW LEVEL
CIRCULATION CENTER IS EAST OF THE MAIN AREA OF ASSOCIATED DEEP
CONVECTION…WHICH INDICATES THAT THE CYCLONE IS BEING SIGNIFICANTLY
AFFECTED BY VERTICAL SHEAR. THE 0000 UTC CIMSS SHEAR ANALYSIS SHOWED
ONLY 8 KT OF SHEAR FROM THE EAST-NORTHEAST SO IT IS SURPRISING THAT
KILO/S DEVELOPMENT HAS BEEN ARRESTED. TOPS OF THE DEEP CONVECTION
HAVE ALSO WARMED AND DECREASED IN SIZE. DVORAK INTENSITY ESTIMATES
CAME IN AT 45 KT FROM PHFO…HELD UP DUE TO DVORAK CONSTRAINTS…
30 KT FROM SAB AND 25 KT FROM JTWC. BASED ON THESE ESTIMATES AND THE
OVERALL LACK OF ORGANIZATION…KILO HAS BEEN DOWNGRADED TO A
TROPICAL DEPRESSION FOR THIS PACKAGE WITH AN INTENSITY OF 30 KT.

THE DETERIORATING CONDITION OF KILO MAKES THE INTENSITY FORECAST A
CHALLENGE. SEA SURFACE TEMPERATURES ARE VERY WARM…ABOVE 29C…AND
THE OCEAN HEAT CONTENT FROM RAMMB-CIRA SHOWS INCREASING VALUES TO
THE WEST. IN ADDITION…VERTICAL SHEAR IS EXPECTED TO WEAKEN THROUGH
48 TO 60 HOURS. THE MAIN INTENSITY OBJECTIVE AIDS POINT TOWARD
FURTHER STRENGTHENING WITH KILO STILL BECOMING A HURRICANE. HWRF IS
THE MOST AGRESSIVE WITH HURRICANE INTENSITY ACHIEVED AT 60 HOURS.
THE FORECAST IS LESS AGRESSIVE BUT STILL SHOWS KILO BECOMING A
HURRICANE IN ABOUT 3 DAYS BASED ON THE OBJECTIVE GUIDANCE AND THE
CONTINUED PRESENCE OF FAVORABLE ENVIRONMENTAL INGREDIENTS. THIS
CLOSELY FOLLOWS THE IVCN CONSENSUS AND THE PREVIOUS FORECAST
PACKAGE. ALL OF THIS MAY BE IRRELEVANT IF KILO IS NOT ABLE TO
DEVELOP SIGNIFICANT DEEP CONVECTION NEAR IT/S CENTER. IF THIS
DEVELOPMENT FAILS TO OCCUR…THEN KILO WILL BECOME A POST-TROPICAL
REMNANT LOW. WHILE SURPRISING…IT IS NOT UNHEARD OF IN THE CENTRAL
NORTH PACIFIC BASIN.

THERE HAS BEEN LITTLE CHANGE IN THE LARGE SCALE PICTURE. KILO IS
MOVING AT 285/12 KT TO THE SOUTH OF A MID- AND UPPER-LEVEL RIDGE.
THE GLOBAL MODELS CONTINUE TO SHOW THAT THIS RIDGE WILL BUILD
WESTWARD TO KEEP KILO ON A GENERAL WEST-NORTHWESTWARD PATH THROUGH
THE NEXT 36 TO 48 HOURS. BEYOND THIS TIME FRAME…A WEAKNESS IN THE
RIDGE IS FORECAST TO DEVELOP…AND THIS SHOULD RESULT IN A REDUCTION
IN FORWARD SPEED WITH A GRADUAL TURN TO THE NORTH OR NORTHEAST. MOST
OF THE DYNAMICAL OBJECTIVE AIDS HAVE SHIFTED WESTWARD TO BE MORE IN
LINE WITH THE ECMWF…BUT THE GFDL AND HWRF STILL SHOW A
NORTHEASTWARD TURN POINTED TOWARD THE WESTERN HALF OF THE MAIN
HAWAIIAN ISLANDS. THE CURRENT FORECAST IS CLOSE TO THE PREVIOUS
PACKAGE AND LIES EAST OF THE DYNAMICAL CONSENSUS…THE GFS AND THE
ECMWF…BUT A BIT WEST OF HWRF AND GFDL.

A U.S. AIR FORCE RESERVE WC-130J TOOK OFF AT ABOUT 22/0100 UTC AND
WAS ENROUTE TO KILO. THE DATA FROM THIS MISSION SHOULD PROVIDE
CRITICAL INSIGHT INTO IT/S STRUCTURE AND INTENSITY. SUBSEQUENT
FLIGHTS WILL TAKE PLACE AT 12 HOURLY INTERVALS UNTIL FURTHER NOTICE.
WITH THE G-IV AIRCRAFT TASKED IN THE ATLANTIC…A WC-130J IS ALSO
SCHEDULED TO DO A SYNOPTIC SURVEILLANCE MISSION ON SATURDAY MORNING
IN ORDER TO SAMPLE THE STRENGTH OF THE RIDGE NORTH OF THE TROPICAL
CYCLONE.

Technology Test Pilot

In 1995 At Maui High Performance Computing Center The Maui Scientific Analysis & Visualization of the Environment Program was first incubated. I was the principal investigator of this independant research project which was a joint development between MHPCC, Silicon Graphics Computers (SGI) & NKO.ORG. Using SGI Cosmo Worlds software, we pioneered the development of Internet based 3D virtual reality GIS based interactive worlds. In 1996 with a network of seven high performance SGI workstations we pioneered development of live streaming MPEG-1, MPEG-2, MPEG-4, Real Video and QuickTime Streaming Server utilizing Kassenna MediaBase software. In Maui 2002 we pioneered and tested the first wireless live streaming video using laptop computers and Maui Sky Fiber's portable 3G wireless device. In Maui we pioneered live streaming video using usb modems from AT&T , Verizon as well as live streaming from iPhone 3 over 3G wireless networks. Today The Maui S.A.V.E. Program has diversified into storm tracking including visualization and analysis of large, memory-intensive gridded data sets such as the National Hurricane Center's wind speed probabilities. I volunteer my services to numerous Disaster Services Organizations. In June 2013 I returned from Hurricane Sandy deployment as a computer operations service associate with the Disaster Services Technology Group assisting as The American Red Cross migrated from a Disaster Response Operation to Long Term Recovery Operations. Pioneering the production/editing and Internet distribution of HD video to sites like Youtube.com and Vimeo.com we are shining the light towards environmental and peace efforts of humans across the globe. Since 1992 I have held the vision of establishing Maui, Hawaii as the environmental sciences center of the world. After His Holiness the 14th Dalai Lama of Tibet came to Maui This vision has expanded to establishing Maui as the environmental & peace center of the world.
