Upper winds, what have you experienced?

[rhys 0]

Today we had some pretty strong uppers... at the peak of the day they were up to 65knots at 18k. at 12k they were about 45 knots.

We were informed by radio that the winds at 25k were 165 knots, I had to ask the pilot again when we were on the ground and that is the figure he was given.

All the airline pilots were changing thier eta's funnily enough.

We were happy jumping as they dropped off below 12k to about 20knts between 10k and 3k and about 0-10knots on the ground from the opposite direction. We have a 12k mountain (range) to the south of us, it was southerly, but no turbulance other than a relatively grunty shear layer at around 12-13k.

The perfect spot was 1.0 miles past and 1.0 miles offset (due to the shape of our valley). So about a mile of drift.

Ground speed on exit was 30knts....

I have jumped in 0 groundspeed before in Queenstown years ago but I don't think we would do that here, so we were close to our upper wind limit for sure...

What do you get where you are? We are in the roaring 40's here I suppose.

I have jumped from 85kts to 8 on the ground.
Done a cross country with 12 @ 70kts. Getting back was easy.
At least, that's what's in my memory from a few years ago.

At the 2010 Nationals the winds were 30kts at 6. When one of the other jump planes landed (while we were in the air), it reported 65kts at 1,500 feet. Needless to say I landed off. Way off.

wow what's the separation between groups at 0m.p.h ground speed?

Wait until they land, then go.

Most puckery spot due to winds - 50kts, crosswind jump run, downtown San Francisco.

Hardest to spot in winds - Santa Anas at Brown Field. 50-60kts out of the Northeast at altitude, 10-15kts out of the West at ground level.

not quite, from 12k wait 50 seconds... ensure you turn 90 degrees to jumprun/windline upon opening.

basically we watched the group before us open and get out of the way before we jumped.

the plane just sat there.

That was 7 years ago at a different DZ (not mine), Idon't think we would jump in those conditions here, it was windy on the ground too when we did that.

True dat. Of course, with those winds, you have time to explain to him that his spot isn't getting any worse.

The plane would have to be flying in a diagonal configuration/ crabbing to keep that run in straight?

they can be difficult to get right those ones.
