NE Pacific Weather Tracking/Study

[Darvince]

Definition of a namable extratropical cyclone:
1. It must have winds at or above 35kt in its near vicinity.
2. It must have a low pressure center.
3. The low pressure center's outermost closed isobar must be 8mb higher than the center.
4. It must be within the Northeast Pacific basin*.
5. Exceptions may be made for storms near the Northeast Pacific basin that are already notable.

*Definition of the Northeast Pacific basin: It is the region of ocean between 180° and 110°W, 20°N and the continental divide of North America, and the Bering Sea west of 180°.

20151215 18UTC BRIEFING

WINDSTORM KEGET HAS DEVELOPED THIS MORNING ABOUT 1000 NMI SOUTH
OF UNALASKA, ALASKA. KEGET SHOULD STEADILY INTENSIFY AS IT
APPROACHES THE GULF OF ALASKA THROUGHOUT THE NEXT 24 HOURS OR SO.
BEYOND THIS POINT, KEGET IS EXPECTED TO INTENSIFY MORE RAPIDLY UNTIL
IT PEAKS AROUND 48 HOURS AND TURNS TO THE EAST.

WINDSTORM JERRY HAS NOW DROPPED BELOW THE STORM-FORCE
THRESHOLD, AND GALE-FORCE WINDS CONTINUE TO DETERIORATE
RAPIDLY. IT IS EXPECTED TO DISSIPATE WITHIN 12 TO 18 HOURS.

20151216 06UTC BRIEFING

WINDSTORM JERRY CONTINUES TO WEAKEN AND IS NOW A MINIMAL WINDSTORM.
THE SYSTEM SHOULD CEASE THE GENERATION OF GALE-FORCE WINDS OVERNIGHT
BUT WILL REMAIN TRACKED AS LONG AS IT IS RECOGNIZABLE.

FAR TO THE SOUTHEAST, WINDSTORM KEGET HAS MERGED WITH A SMALLER LOW
PRESSURE TO ITS WEST AND HAS PREVENTED THE SYSTEM FROM GAINING
A MODEST REPRESENTATION ON SATELLITE. ALTHOUGH, THE SYSTEM APPEARS
TO BE REORGANIZING AND CONTINUES TO STRENGTHEN. IN ADDITION, KEGET
SEEMS TO HAVE GENERATED A NEW CIRCULATION CENTER NEAR 150W, A
SIGNIFICANT JUMP EAST FROM ITS PREVIOUS LOCATION. THIS IS LIKELY A RESULT
OF THE NEARLY COMPLETE MERGER. RAPID INTENSIFICATION OF THIS SYSTEM
IS EXPECTED THROUGHOUT THE NEXT DAY OR SO.

Also, I've created this document so that dar can help to edit track data and other summaries and stuff. I'm not sure exactly what you want to do but I feel like it should have more than just the tracking data

wait I thought ascat only went up to like 50kts

[atomic7732]

me too

i think it has to do with convection, so like you're never going to see a TC with 90 kt winds, but extratrops are more naked generally so idk

yee

[Darvince]

why did you change from the old format

[atomic7732]

i didn't really like it

i wanted it to be more concise, cover more things, look less like advisories, and look more like summaries

but the advisories were useful for past tracking, so that's why i added that tracking data doc, so that if you or i want to go back on the stuff we missed (usually 12z) we can put it in the track file whenever and not have to write a summary or advisory for it after the fact
