Oh, the weather outside is...

She's clearly behind the times. She doesn't have a weather app on her phone. :p
 
Had that conversation with my son. Look kid, you can see almost five miles in the direction the wind is coming from. You're going to know it's going to rain before it rains and with enough time. You aren't painting a house. :lol:
 
I thought the curvature of the Earth generally limited the horizon to three miles at sea level?

That's why castles in the air are hidden between the higher up clouds

So you can see further than ordinary earth worms with all their limits
 
Yea, but if you're worried about storm fronts blowing in, you can see them from farther than picking out watertowers and windmills and whatnot based on the ground. Like a lot farther if the air is clear. I figure it's not close until it's within 5 and it might be forming over you anyways. The weather station the cell phone apps use is 10 miles away from where I'm generally standing anyhow, so it's not like it's ever going to beat you looking out the window for at least the next 10 minutes or so. Still helpful to have an idea about the afternoon. Still wrong a lot tho.

Looking west we can see 85 miles on a clear day. Looking east we see 5000 feet of mountain about 5 miles away.

My wife tracks the weather on Weather Underground. I, like Tim, look out the window.

Sunny and in the 60s today.
 
Where are you now ?

Somewhere Lyon ?

Close...well, kinda, in Marseille.
It's just amazing. I wanted to change country to live for some time with good weather, and I exactly got it. Although it's apparently also unusual even for here. It's windy though (not always), but less humid than in NL. The temperature is maybe not even the main selling point, but that the sky is clear is just really great.

That's if you are looking for things at ground level maybe. Things at the altitude of clouds can be seen from a whole lot farther than that. Heck, just the mast of a sailing vessel can be seen sticking up above the horizon for a lot further than that.

Don't tell flat earth believers that

They think that you always see the whole ship... smaller or bigger

Unless they believe the diskworld theory of light...that it falls as it travels so you can see the mast from further away due to the greater originating altitude of the light allowing it to travel further before hitting the ground.

Incidentally, the world HQ of the Flat Earth Society is not very far from my home. If it were at the altitude of the clouds I could probably see it from here.
 
The Earth's curvature was decided upon...?

More like some arbitrary "how far is the horizon" was decided on. Since how far you can see something is dependent on your height and the height of the object there really is no such thing as "the horizon is this far away," so may as well base it on how far you can throw a cannonball.
 
IITC, the 3-mile limit was decided upon because that was the maximum range of canons at the time.

IDK to what time you refer

The range of naval canons was not so important because of the short engagement distances.
Naval canons were not mounted so that you could get high elevation angles.
Here a link to an article I found on that: https://www.globalsecurity.org/military/systems/ship/sail-armament.htm
The standard naval 24 pounder of the 18th century had an effective range of less than a mile.
The importance then of allotting to all ships the largest cannon they can with safety bear being granted, it remains to show on what foundation a change is proposed to be made in the fabric of all pieces from eighteen pounders downwards, so that they may be changed for others of the same, or less weight, but of a larger bore.

The 24-pound guns each required a gun team of 6-14 men to operate and weighed about 5600 pounds. They are called 24-pounders because they fired a cannonball that weighed 24 pounds. Although the solid 24 pound shot is what was commonly used, the guns could be loaded with a combination of projectiles. The long gun possessed one great advantage: it could far outrange the carronade, and if well operated had a chance of crippling the enemy before coming to close quarters.

The normal gunpowder charge used for these guns was six pounds and their maximum range was about one mile at maximum elevation, but due to inaccuracy at that range this was literally a "long shot." The maximum effective range of a 24-pounder was about 1200 yards. The usual engagement range, however, was much closer. CONSTITUTION engaged HMS Guerriere in 1812 at about 25 to 50 yards. At this range CONSTITUTION's guns could do terrible damage, with her cannonballs penetrating over two feet of oak planking.

The 32-pounder Navy gun [length 112 inches, 57 hundredweight] was intended service was on first class frigates and ships of the line. A total of 744 smoothbore guns of this type were manufactured at five different foundries from 1846 to 1852.

There was already in the late 15th century the falcon (or falconet) that could shoot that 3 miles. More a kind of big musquet. Originated on land but was widely used for special purposes at sea. Projectile weight somewhere 2 pounds.
 
That was the wettest February on record for much of Ireland, the nearest weather station to me had 283% of average rainfall, 248mm of rain for reference.
 
My company is slowing down operations due to the coronavirus so I took a day off next week.

It was forecast to be rainy that day, now it isn’t! :cool:

Right now something around 40-50F, kind of holding around that area for the next few days. Partly cloudy afternoons but the mornings and early afternoons tend to be pretty good.
 
Sunny and 60 today. I'm going to go out fort lunch.
 
There's a low-speed cyclone parked off Baja California that has blessed us with a lot of rain. :D It's so nice.
