Latent Heat Slows Condensing On a micro scale, when a molecule of water condenses out of the air by joining a water droplet it transfers its higher kinetic energy to the droplet warming it. On a macro scale, if all the water tried to condense out of the air at once, the temperature of the cloud would rise to the point where much of the water would want to ...

The lightnings primarily depend on strong electrostatic fields. They're up to 100 volts per meter in the summer and 500 volts per meter in the winter. These fields are fluctuating. When a certain critical threshold not far from those values is reached, a lightning strikes. Does the electrostatic field move a metal? There is no direct electrostatic force ...

Analogous to the tides of Earths oceans, do the Moon and Sun cause our atmosphere to bulge in what could be described as a low and high tide? The answer is yes, if you generalize beyond gravitation. Sunlight heats the atmosphere, and this causes atmospheric tides. The two dominant effects are absorption of visible and near infrared sunlight by water ...

The differential force of gravity on the atmosphere works the same as it does for the rest of the earth (the oceans etc). However, moving the equipotential surface by a few m will be almost undetectable on the atmosphere, since the density of the atmosphere decreases so gradually – over many km. Contrast this with the surface of the ocean, which ...

You have picked a very striking picture to illustrate your question, although the northern lights do not always have such a sharp lower border to them. However, let me advance a plausible explanation. The green northern lights are formed high up ($\geq 100$ km) in the Earth's atmosphere, largely by photons at 557.7 nm emitted from excited oxygen atoms. This ...

For any sample of atoms in a gas they have a range of speeds. The likelihood of any atom having any particular speed is given by a probability distribution called the Maxwell-Boltzmann distribution. But the main point is that low mass atoms are more likely to have high speeds. For hydrogen and helium at temperatures typical of Earth's atmosphere there is ...

They don't go up and leave earth or its atmosphere. The atoms go up because they are lighter then the other atoms and molecules in the air, but they still have mass. They float over the heavier atoms and molecules. They don't leave earth's orbit or go in space but they go very very high. its all because of the gravity and pressure. Atoms swap places, the ...

If the moon is on the opposite side of the planet while the sun is over our heads, I would be under the impression the moon pulling the atmosphere towards it would allow warmer days or cooler nights as the atmosphere is thinner during this time.

If the electric charge from lightning is captured and harnessed through circuits, eventually it will reach the ground, but once there it will join the general discharge process mentioned by Feynman. It won't lead to any build-up of charge. Incidentally, it would be very difficult to harness lighting with sufficient regularity to make a difference to the ...

I was looking this up to see how common sonic books from meteors uccur. I was on my roof two nights ago finishing up a project after dark. A light caught my eye. As soon as I looked up I herd a boom right as a meteor shot derectly over my head. It was a red and white streak from north to south. It was huge for a shooting star. The boom came from the ...
