what is the scientific explanation of falling snow and thunders?

Answer 1

Thunder is not the sound of lightning hitting the earth!

Thunder is created when there is rapid heating of the atmosphere. It causes the air to expand and contract, and this expanding and contracting makes the sound you hear as thunder. Many believe that the heat from the lightning causes this rapid heating, which causes the sound, but it is definitely not the sound of the bolt hitting the ground (lightning doesn't always hit the ground)!!

And I'm not really sure what kind of explanation you are looking for with the whole falling snow thing but, Snow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds.

If you meant an explanation of why it thunders while snowing, it's called Thundersnow. Thundersnow can be found where there is relatively strong instability and abundant moisture above the surface. Instability in the atmosphere during thundersnow is usually caused by a warm front, and this instability could carry along some lightning and thunder with the snow.

Answer 2

Snow begins its life as water vapor. You really need a temp below freezing but above -40 in the clouds. When the water vapor encounters a freezing nuclei, it begins to accumulate onto it. This is how snow is formed. When the snowflakes are big enough to overcome any updrafts that are keeping them aloft, they start to fall. If the temperature remains freezing all the way to the ground, it will remain snow all the way to the ground. If the temperature is above freezing in some area above the ground but then returns to freezing near the surface, you may end up with freezing rain or sleet. If the temperature does not go back to freezing, it will be rain.

Thunder is pretty much a sonic boom resulting from lightning rapidly heating and expanding the air.

You can get thundersnow. This is where snow is formed by convection, much like in a thunderstorm. When thunder occurs during the snowfall, it is called thundersnow.

Answer 3

Water falls to earth, adn then re-evaporates. When the water rises, it takes tiny grains of positively charged dirt with it darkening the clouds. This creates a static electricity charge in the cloud (frozen water vapor). When it reaches a critical point, lightning is discharged to earth (the electrical ground). When the lightning passes through the air, it turns the atoms of atmosphere into plasma (cahrged particles). They release light and instnatly vaporize the water around them. This creates a shockwave, that is thunder.

Snow is precipitation that falls and never has a chance to melt because it is too cold.

Answer 4

falling snow is water that has been released from clouds. because the air is very cold when it fall (due to gravity) it freezes and turns to snow.
thunder is the sound of lightning hitting the earth. because the speed of light is faster than the speed of sound, you see the lightning before you hear it. a good guess for how far away the lightning strike was is to count the number of seconds there are between the time you see the lightning and hear the thunder. that's how many miles away the strike was. Ex: if you see a lightning bolt hit the ground far away, and five seconds later you hear thunder, then the bolt hit five miles away.
hope this helps.
