2012-02-14 01:18:08 - How to get long range forecasts from NCEP
Go to: http://www.emc.ncep.noaa.gov/
Select: GFS logo
Under U.S.-No America select: "View more model forcasts"
This takes you to "Model Analyses and Guidance" page.
Select: "Model Guidance"
Select an area (for SOL WR leg 4 select "Asia"
Select a Model Type (start with "GFS")
This will load page with "Available Model Cycles"
For surface winds select "10m_wind_precip"
That will load a box of colums with projected winds from 3 hours out to 384 hours out. Select any and a chart of the projected Wx for that day and hour will load. This can be saved as a gif file. From the chart page you can return to the Available Model Cycles page to select another time in the furture.

Very helpful - thanks Jack...

Be interested to look at some of the other models implied in your post - they can often be helpful when trying to predict how later winds will change from the current forecast
I help develop the client interface for the best online ocean racing sim there is... __/)/)_/)__

Are these published earlier than NOAA's grib file runs?

Saildocs is also a good way of getting long range forecast.

If you send the following to queryATsaildocs.com...
Subject: anything you want
Body: send GFS:40N,61S,40E,140W|1,1|0,6..336|PRMSL,WIND

... you get the grib file for the specified area and timeframe in return.

You can also subscribe...
Subject: anything
Body: sub GFS:40N,61S,40E,140W|1,1|0,6..384|PRMSL,WIND days=0 time=23:00 interval=6

... and you get this sent to you 5 min after each time interval starting from 23z tonight. (Saildocs runs subscriptions 5 min after every 1/2 hour and the full 384h run is normally finished by then).

Skimmer Dragonfly - India to East Africa 2026


In the autumn, when the rains stop and the tourists thicken in Goa and along the north western coast of India, globe skimming dragonfly climb to the skies (up to 1500m) to catch the high-altitude ITCZ winds and glide south west to East Africa. We’ll stay at sea level, where alas the winds will be less predictable, and race them there, the whole 2400nm of the way, in Carkeek 40s.

Mad Max by Balloon 2026 - Across the Outback


Mad Max Rockatansky doesn’t get to go in a balloon in any of the Legends of the Wasteland, and the Wasteland is not necessarily the Outback of Australia, but Mel Gibson and film director George Miller indubitably are… of Australia, and ballooning as reconnaissance is a main feature of the Mad Max spin-off video game, so here goes: 1500nm in a balloon from somewhere on the edge of the Outback, Goondiwindi, to cross a finish line at Fitzroy Crossing, somewhere on the edge of the Outback!
