polar vortex the sequel

[Krazy4Real]

I've been so miserable with the weather.

 

[sdifox]

Currently -17, -28 with wind chill

This is the north side view from my store this morning.

WTH is this white stuff?

You can't drive on it. It's all slippery. This is Louisiana. We have no idea what to do with this shit.

 

[OCGuy]

It is scary how good the weather has been. We will pay for it.

Time to bring out your drum of Nepalm


btw, clear your walkway/sidewalk. You are liable if someone falls on the sidewalk.

Be thankful, it keeps the mosquitoes at bay for a little while.

Until they figure out if they drink more blood they would be warmer :whiste:

 

[Iron Woode]

its -19C and -29C windchill.

He doesn't have a shovel! Maybe he could use a broom. And LOTS of table salt.

Should just do what I would do if I lived in Louisiana. Stay inside for a couple days and let someone else take care of it.

push broom with stiff bristles is excellent for snow removal on interlocking and landings.

I am loving this weather. it has been below freezing for the past few weeks. Perfect for small and frequent snowfall to keep all of the ski slops fully powdered up and covered. And perfect temps for snowmakers to continuously add to the base.

Also great weather to do some outdoor exercise. When hiking, snowshoeing in this weather, your body expends extra calories to keep up your core temps and you get an even better workout.

Aren't you already paying for it in terms of record droughts over there? That's gotta be related somehow or another I reckon

The weight you're losing is fingers and toes dropping off due to frostbite.

just buy a bag of cat litter, wont melt anything but it should keep people from slipping

you're in CA... there's a lot of things you already pay for

Not many calories though. A food calorie is a kilocalorie, the amount of energy needed to raise 1 liter of water 1 degree celsius. Unless you're shivering, you're not really burning many extra calories. And, if you're shivering, you're not dressed appropriately for that activity & probably not enjoying that activity. I dare say that when cross country skiing, the cold temperatures aren't causing you to burn extra calories - the cold temperatures are making it easier for your body to shed all that heat from the calories you've burned.

Sort of like driving a car across a hot desert - it's more likely to overheat in the desert, but if you drive it during the winter, it's not going to burn extra gasoline to keep the engine warm.

It may be hard to quantify exactly how many extra calories are being burned, but it does make sense that the body will burn more calories in a cold environment to maintain a core temp. It certainly is much easier to not overheat when exercising in the cold. But think of the cooling effect each time you breathe. That cold air is going right to your lungs and the center of the body cooling you from within. I feel like the body must work harder to replenish all of that lost heat exhaled. If you are doing a hard exercise like xcountry skiing, perhaps not much extra. But when you stop and take a break or when doing light activity like merely taking a walk, I would think that the body has an extra demand due to the cold temperatures

On the flip side, if you drive a diesel vehicle, you'll know that cold temps affect it as well. Diesels have greater difficulty starting in the cold. Diesels like to run hot and depend on heat from the compression stroke to ignite the fuel. I can see a marked difference in fuel economy when the temps are 35 and above and when they are 5 degress. In 5 degree temp, the engine struggles to start and even when warmed up, the car gets worse mileage. Warm the temps up to 35 and I get far greater mileage. I've theorized that the colder temps make ignition more difficult and thats what affects the mileage and leads to more fuel consumption. My experiments were all done on winter blended diesel so that removes the seasonal difference in fuel quality.

When wondering about my worse fuel economy in frigid temps, I theorized about the human body and think it is similarly affected and consumes more "fuel" and requires more "internal heating" in cold temps.

I think cold air is also denser and changes up how the ECU mixes fuel and it runs more rich in the winter.

Something like that, because I thought that at the basic level - efficiency in most gas engines is theoretically higher when there's a greater difference in temperature between the interior temperature and the temperature of the air. I.e., ceramic engines showed a lot of promise because of their ability to work at higher temperature could lead to more efficient designs. However, there were other drawbacks that made them generally undesirable.

Strictly speaking, this is true. Your body doesn't have any kind of direct thermal heating, your body heat comes from moving around and the internal processes that go on regarless of whether you're hot or cold.

But, I'd still argue that you can burn more calories in cold weather, just because you stay more comfortable, and your body's ability to cool itself more effectively allows you to work harder.

Man, it won't stop raining. Everything is covered in ice. Reminds me of living in Indiana. Work was closed today and after this downpour, I have to believe it will be closed again tomorrow.

Gotta love Southern drivers. About 2 inches of snow and the entire city is in gridlock and panic. It took me 7 hours to get home. Normal drive time is 20 minutes. Everyone was spinning tires because of the gridlock traffic. What a shitty experience. I thought about abandoning my vehicle and just walking home. It would've been heck of lot faster and safer. Streets were unsafe because everyone was driving too damn slow!

 

[gorcorps]

Roads are all plowed which is nice, but the roads are also covered with snow pack with ice hiding underneath. Intersections can be pretty dangerous even if they don't look it

 

[jaedaliu]

Heard on NPR this morning. Birmingham got hit with snow/ice when they weren't expecting any. Someone was interviewed at a gas station. They had driven 1 mile in 7 HOURS and had to get gas.

Yeah, when I move back to a warm weather state, I'm calling in sick/emergency vacation if it's snowing.
