Temperature 15°, wind gusts up to 33 mph — a good opportunity to test the meaning of the notion of the "feels like" temperature...

18A4FB21-91E1-496E-BA7B-F3C224F5E247_1_201_a

... which was -5°.

Answer: My face got quite cold, but I've been in actual -5° cold, and I wouldn't say it felt that cold as the wind was gusting, but I did wish I'd brought a scarf to cover my cheeks and nose. The rest of me was just fine, even a bit hot.

Side issue: Running around trees in the wind is dangerous. I saw one downed branch, and I heard some creaking. You really can get killed out there in the wind.

ADDED: So what is the wind speed that should make you decide against being out around trees?
- at 32 to 38 mph, whole trees will be in motion....

- at 39 to 46 mph, branches and limbs can be broken from trees....
That sounds precise, but imprecise. Surely, the type and age of the trees must matter.  Wouldn't the temperature and the moisture level affect breakage? And then there's the question whether these trees are maintained. In our neighborhood, there are lots of big, old trees, but people are supposed to tend to them and get dead branches removed. We have a 200-year-old tree in our yard — along with other big trees — and we spend lots of money on arborists who take out the dead branches. I run in the woods, but it's the university's woods, and it's extremely well kept. So what does that mean? Go ahead and run as long as it's not gusting over 38 mph? Who knows?!

You're right Althouse. Trees and high winds are dangerous. My husband lost his sister to that combination.

The limb hit her head and she spent twenty two years severely brain damaged before finally succumbing.

Please be careful.

Worse, camping. I took my two sons on a Boundary Waters canoe trip. Howling winds the whole long weekend we were there. Very little soil for the trees to root, constantly saw trees falling during the day as we were paddling. Didn't get any sleep because kept thinking of a tree falling on the tent....

Feels like is a scam, to get clickable temperature stories.

Moisture freezes on your nose hairs and is feelable at say 10 degrees, but won't at 15 degrees no matter what the wind is.

I heat the garage, and shop with wood only. The house has a propane heater, but I also heat with wood and coal. I have to cut a lot of wood, but I never go out there if it is windy. Just walking around, I see numerous large branches on the ground. They snapped off from the wind.

"So what does that mean?"

It means that when your number's up, your number's up.

"A rich and mighty Persian once walked in his garden with one of his servants. The servant cried that he had just encountered Death, who had threatened him. He begged his master to give him his fastest horse so that he could make haste and flee to Tehran, which he could reach that same evening. The master consented and the servant galloped off on the horse. On returning to his house the master himself met Death, and questioned him, 'Why did you terrify and threaten my servant?' 'I did not threaten him; I only showed surprise in still finding him here when I planned to meet him tonight in Tehran,' said Death."

Leaves or not means a lot. The air resistance goes up a lot when there are leaves on the branches. Also wet leaves weigh a lot.

I remember skiing where I heard afterwards it was -60 wind chill. Pulled up my scarf, which fogged my glasses, which froze onto my nose. Finally got them off but not cleared. I should have noticed no one else was using that lift.

I generally don't like to run in high winds. Not so much out of the fear of death or injury, it just is very unpleasant, especially when it's cold. I do it though, sometimes. If I'm not going to have any other time to go, I'll put up with it.

I've had branches fall near me. Big ones that could have hurt me badly it they had landed on me. You have a warning, there is a big cracking sound before they start to fall. I have fast reflexes, but it isn't enough time to get out of the way. By the time I figured out where the branch was going to land, it was crashing to the ground.

The wind is good for outside clothes-drying. But man! Did my fingers ever get cold while hanging things out late last night.

rhhardin म्हणाले...

Clothes drying outside doesn't work very well when it's cold. The evaporation rate is too low. Just let the clothes sit on a rack indoors where it's hyper-dry already.

A little something I learned from living in South Florida:

A now-deceased close friend owned a fence company in Miami. He made a pile of money after Hurricane Andrew in 1992. One day I asked him what type of fence held up worst in tropical storm/hurricane winds. He immediately answered "Chain link".

He explained that yes, the wind passes freely through it. But the result is that it acts as a trapper for everything blowing in the wind, like leaves, trash and other debris. It doesn't take much time to trap enough that the high wind pushes the fence over.

You can get a notion of super cold if you spill gasoline on your fingers (say refueling an airplane) when it's noticeably below freezing. Unlike water, the cold doesn't bottom out at 32 degrees with gasoline. -40 to -200, say wikipedia.

I took a skate-skiing class when it was about 10 degrees and got real sick later. That's a real workout and I wasn't up to it.

My doctor missed the strep symptoms and it was finally diagnosed a month later.

The author of that piece–Christian Schneider–sent a freedom of information act request to the University of Wisconsin-Madison asking for all the complaints filed with that university’s “Bias or Hate” reporting web site. He got back 107 complaints. One of them was a complaint by a student against a professor who had said in class that some theories and beliefs are “scared cows” that cannot be critiqued in academia. The student, who wrote that he “grew up in India,” called the professor’s use of the term racist.

I’d like to see a lot more of these freedom of information act requests for complaints aimed at bias response web sites. This stuff needs to be exposed.

It's never a good idea to go hiking or running alone in a remote place where if something happens to you (severe ankle twist or a fall) and you are not found within an hour or so you might die. Also a good idea to have someone with you to talk you out of trying to do something super risky. https://www.bbc.com/news/uk-england-essex-51500453

In real life, normal people would go outside with a chainsaw and maybe a hockey mask. Maybe in real life or not after Valentines day. My facts are a bit scewed. I'd recommend always wearing a helmet. I wear a helmet for my bicycle because I usually bonk the object I'm chaining or retrieving my bike from. But that's too much too long for death to decide when to throw tree branches at humans. Haven't anyone seen Lord Of The Rings ? The trees are usually neutral but do conspire amongst themselves. If people do not use Tide laundry detergent, the trees may question ones existence. Winds can also drop houses on witches as per The Wizard of Oz. Heed caution or make snow Angel's in an open field. Colder but safer. Cheers

Ken Levine is a writer that worked on Cheers, M*A*S*H, Frasier and many more sit-coms. Needless to say, he is a fascinating man with fascinating stories. Even though he is a raging liberal, I adore him. Comedy transcends politics.

He writes a daily blog post, and this was today's.

A reader asked me recently to talk about my sordid days doing improv. I started in 1979. Disco was dying and I was looking for the next big thing. My partner, David and I sold a pilot to NBC about a Nichols & May type improv team. The concept was could a man and woman work together and just be friends (long before Sally faked her orgasm for Harry)? To research the arena I called Dee Marcus, director of the improv group OFF THE WALL (still in existence, still performing around town, and still hilarious) and asked if I could audit a class. She said only if I agreed to participate. I figured, what the hell? I couldn’t be much worse than the other beginners.

I arrived and was blown away by how unbelievably great everyone was. SNL quality people performing over a beauty school at Santa Monica Blvd. and Fairfax. These were the beginners? Shit! I was lucky to get through a scene without pissing on myself (although, I know I passed up a sure laugh) After a few trying weeks of this I learned Dee hadn't put me in the beginners class, she put me in the performance class. These were all the top professionals. (Thanks, Dee) The tip off came when Robin Williams showed up one night.

I stayed in the class for a couple of years, learned an enormous amount, and eventually became part of a comedy troop, THE SUNDAY FUNNIES. We played to crowds often fewer in number than the cast.

After many years of sabbatical I'm back, taking Andy Goldberg’s workshop. Of all the improv teachers he’s by far the best. As a comedy writer I recommend improv training. It teaches spontaneity, committing to a character, and creating scenes with beginnings, middles, and ends. The hardest part is going to a deli afterwards and watching your classmates eat fried kreplachs at 11 at night.

One story about Robin. Needless to say, doing scenes with him was an adventure. He is so fast and brilliant he just uses you like a prop. One night I got called up to do a two person scene with him. If you were lucky you sometimes could get in two words. The scene began, he went off in fifteen different directions. I didn't even know what the hell he was talking about. Finally, I heard a beat of silence. He must've been taking a breath. Now's my chance, I thought. I don't know why but the only thing I could think to say was "fuck you". Much to my surprise it got a laugh. He was off and running for two more minutes of inspired word jazz and then it was my turn again. Since it got a laugh the first time I said, "fuck you". It got an even bigger laugh. This became the scene. Robin riffing, me occasionally blurting out "fuck you". And every time I got the biggest laughs.

When the scene was over I worried that Robin would be pissed that I upstaged him. Instead, he took me aside and said, “that was great.” I consider it one of my greatest achievements in comedy.

And I guess he remembered it because every time I saw him the first thing he said to me was “Fuck you!”

According to settled science randomizing your workout patterns increases the efficiency of conditioning. When mother nature is telling you to stay indoors you can always use that as an opportunity to optimize your random schedule. Also, I hope you are not wearing your earbuds while running, not just in the high winds. There's lots of things that can bite you in this world, mother nature does not offer social exemptions for females and taking away one of the most vital senses wouldn't be prudent.

My face got quite cold,

They use the face for calculating "feels like" temps:

"Calculates wind speed at an average height of 5 feet, the typical height of an adult human face, based on readings from the national standard height of 33 feet, which is the typical height of an anemometer

Is based on a human face model

Incorporates heat transfer theory based on heat loss from the body to its surroundings, during cold and breezy/windy days

Lowers the calm wind threshold to 3 mph

Uses a consistent standard for skin tissue resistance

Assumes no impact from the sun, i.e., clear night sky."

How many people have been killed in Madison by falling Tree Limbs in the last 50 years? I'd guess....zero. Icy pathways are probably more of a danger than wind and Trees. Although, I wouldn't go running under trees during a Hurricane.

"According to settled science randomizing your workout patterns increases the efficiency of conditioning. When mother nature is telling you to stay indoors you can always use that as an opportunity to optimize your random schedule."

I'd already done that on Thursday and Friday. Today, the temperature was up. 15° is no problem at all, I know very well, but I had some question about the wind gusts. I learned something today, but mainly just to bring a scarf for my face.

"Also, I hope you are not wearing your earbuds while running, not just in the high winds. There's lots of things that can bite you in this world, mother nature does not offer social exemptions for females and taking away one of the most vital senses wouldn't be prudent."

I wasn't wearing my airpods today, but I wear them sometimes. I've experimented, and I now believe that listening only to the environment produces the best overall aesthetic experience (and I mean that without regard to questions of safety that weigh in favor of maintaining the highest level of awareness).

Gospace म्हणाले...

Temperature, moisture, ice cover, wind speed and wind direction. ¼" of ice on the branches can add a lot of weight. If the wind normally blows from the west, as it does in most of the U.S., some areas more consistent than others, the trees and branches grow to resist forces from that direction. They'll be less able to withstand wind force from the opposite direction.

Another thing about wind many people don't understand. Doubling the windspeed causes an 8X increase in force on whatever it's impacting against.

Running through a well maintained grove won't keep you safe from falling limbs. Too many unpredictables. Being fully aware of and observant of your surroundings will keep you safer. Not safe- but safer. Never rely on others to keep you safe.

"Wow. And here I was this morning delaying my run for about an hour because I wanted to go out when it was over 30 degrees."

When it's over 30°, I wear my lighter jacket.

When it's in the 20s or lower, I wear a jacket that actually isn't very heavy. It's a jacket I use for walking only when it's over 40.

When it's in the 30s here, I see younger runners with no jacket at all and sometimes in shorts. I'm sure they feel fine.

Birches म्हणाले...

I never wear a jacket to run, but I have long sleeves and tights, as I did this morning. The sleeves usually get pulled up after the first mile, but I really hate being cold so I'd rather have the sleeves at the beginning.
