Wind going both ways?

InSydeOut

Rookie
Was rallying with my partner at a new court we never played before. We both felt a huge difference in the behavior of the ball.

1. The balls were flying longer. My topspin FH I expected to hit around the service line were now reaching baseline.
2. The balls were flying faster. My FH (my best shot) felt rushed and I almost gave up on my BH.
3. Low balls I expected to hit the top of the net made it over. It almost felt like the ball caught a wind current and made it's way over the net.

The courts were not in great shape. The courts we usually play at were much better kept. Surface felt sponge like. However we were surprised how fast the balls were flying and bouncing.

I was wondering if anyone experienced this? There was a faint breeze today but nothing that drastic. Also how could it affect both of our shots in opposite directions?

I will mention that the courts had a hill behind myself and woods behind my partner. Almost like its in a little valley. Possibly a wind tunnel effect?
Just frustrated at how poorly I hit, and want to know why!

Where the balls themselves different? Standard duty versus extra duty? Cheapo budget ball rather than a premium or decent ball?

No windscreens? Poor or uneven lighting?

Swirling wind?

How was the ambient temp, humidity & the barometric pressure? How about the gas profile of the atmosphere at those courts? Was it similar to the preferred percentages shown here:

Maybe you found another “mystery spot,” like the one in Santa Cruz, CA.
I believe that you may have hit upon the primary reason for the OP's experience / observation. This tennis court court very well be located in an area, like the Santa Cruz "Mystery Spot", known as a gravity (or magnetic) hill.

Such areas appear to exhibit gravitational anomalies & will often produce remarkable optical illusions. In these areas, water & balls appear to roll uphill.

Is it too much to ask that outdoor courts have some kind of forcefield to counteract in case of gravitational anomalies?

Private clubs and your better public outdoor courts will have this installed. It should be recalibrated as part of the resurfacing process every few years

OP, you should contact your local government to see if the Parks and Rec Dept can take care of this.

what was the surrounding landscape...
i typically experience changing winds when there are hill contours around the courts,
on the corner of an alley of buildings (eg. in nyc the buildings will funnel the wind)
in storm like weather... all storms are spining, so depends how big the storm is and where/when it's passing (ie. the front vs. the "back" of the storm
nearby walls/windscreens will cause "swirls"
etc...

I have been to the ******* one. Very odd behavior. Balls roll uphill.

Your Mystery Spot remains a mystery spot since the forum software saw fit to bleep it. So, I'm going to attempt to clean the name of your "gravity hill".

I'm thinking it is either Booger Hill at Cumming, Georgia. Or maybe it is on Pleasant Valley Road in Titusville, NJ.

Hmmm, neither of those got bleeped, so I'm at a loss. Where is your gravitational anomaly located?

Nope it is in a mitten. How is that for a clue!

Bad-mitten (aka Badminton)?

Would it be a reference to the Mitten Brewing Co in Grand Rapids Michigan? Nothing else comes to mind. Certainly nothing that would conjure up TT forum bleeping.

An anagram of "A mitten"?

Things in a mitten: hand, fingers, thumb, knuckles, nails, and a Rosy Palm.

Several urban myths concerning various gravity hills talk about hand prints that magically appear on the back of cars that roll "uphill".

A mitten = Tan item? Ant time? Mean tit? Min teat? Mint tea? Mea tint? Eat mint? Mia tent?


White clouds, I'm in
The mitten full of fisherman
C'mon Huckleberry Finn
Show me how to make her grin
Well I'm in Michigan

Cry me a future
Where the revelations run amok
Ladies and gentlemen
Lions and tigers come running
Just to steal your luck

Out on the farm we'll be
Swimming with the mother duck
Deep in the mitten where
Lions and tigers come running

Just to steal your luck

How about the state... mitten....mitten state.
Not familiar with the nickname. Is that how Cheeseheads from Wisconsin refer to Michigan? RHCP apparently think so. Wiki actually lists three different gravity hills in MI. One of the three is this:

Blaine Township (near Arcadia): Putney Road south of its intersection with Joyfield Road. Cars appear to roll toward the church at the intersection. Local legend claims the church is pulling sinners towards its doors for redemption.

I am in Kalamazoo for the tournament which made me think of the following which I visited with some friends many years ago when I was a college student:


I did not know about Blaine Township.

Most courts are set up north/south and designed as a "single" plane surface with a gradual slope to one end or side.
It is remotely possible that the court you mention has deviated somehow from the norm- enough to create a physical
or psychological difference.

The most obvious problem would be if the court drains inward toward the net- causing the two sides to slope
down and make the net (in effect) lower in relation to the baseline. This might explain some of the sensations you
Experienced.

Or not.

This is a distinct possibility. Most outdoor courts, at most latitudes, will be very close to a N-S orientation. Not necessarily true for courts close to the equator (perhaps within 20-24° or so of the equator). Orientation at those latitudes is somewhat less critical -- depending on the time of the day that these courts are normally used.

I'm at a latitude of ~37° N. Nearly 95% of the outdoor courts around here appear to be very close to N-S. There are a few very notable exceptions. ClubSport in Fremont has most of their courts indoors. But they also have three outdoor courts that are oriented in the same direction as the indoor courts. While the E-W orientation doesn't matter for the indoor courts it's a huge problem during much of the day for the outdoor courts. If they had properly oriented the outdoor courts N-S instead, they could have fit 4 courts out there for the space they had available.

The Taube Stadium courts at Stanford University are way off the N-S alignment. Easily more than 35° (maybe even more than 45°). The footprint was set down in 1929 that way because it lined up with Campus Drive that circles around much of the campus. I guess they didn't want to use up too much real estate by having the courts properly aligned to the Sun.

I've only played on those courts in the evening so it was not a problem for me. I would never play on those courts during the day tho. The courts across the street at Taube South are perpendicular to the ones at Taube Stadium. This is also a bad angle.

However, behind Taube South there are 2 sand (beach) volleyball courts. These two courts are side by side and are lined up nearly perfectly, N-S, as they should be.

Perhaps even worse than playing on misaligned courts are playing on courts that are peppered with light and shadow during the day. It is extremely difficult to track tennis balls as they transition between light and dark and back again.

Courts without windscreens can be an issue, not just because of the wind factor, but without screens, you may have a background that makes it very difficult to track the ball. A blue windscreen is best for optic yellow balls. A dark green screen is the usually next best thing.
