some strange/interesting facts about rain!
Hope you enjoy!!
Not all rain drops that fall from the sky reach the ground. Under specific conditions, sometimes rain can fall but never touch Earth. This occurs when rain falling from a cloud evaporates or sublimes as it draws closer to Earth’s surface.
When this happens, it forms what is known as ‘Virga Clouds’; a tail or wisp extending from a cloud in a downwards position. Generally, these are seen to extend from Cirrocumulus, Altocumulus, Altostratus, Nimbostratus, Stratocumulus, Cumulus or Cumulonimbus clouds.
Grateful for Rain!
‘Petrichor’ – the smell of rain
When raindrops fall on clay or dusty soils, they trap small air bubbles on the surface which raise upward and burst out of the droplet. This then produces pockets of scent into the air where they are then carried by wind.
This is what causes the familiar smell of rain.
Let the rain
Shape of a raindrop:
Raindrops are usually represented in the shape of a teardrop, but this is not true in reality.
When raindrops first form high up in the atmosphere, they take on a spherical shape as the water molecules bind together held by surface tension.
As they begin to fall their shape changes, while air resistance causes the bottom of the drop to flatten and curve resembling the shape of a jelly bean.
“And far away, like in another world,
we could hear raindrops of roses and whiskers on kittens.”
~ R. J. Palacio
How long does it take a raindrop to reach the ground?
To provide the exact figure would be difficult. The height raindrops fall and size can differ. But following an average speed of 14mph and an average cloud height of 2,500 feet, it would take two minutes for a raindrop to hit the floor.
Very small raindrops can take as long as seven minutes to reach the ground; while larger droplets can fall at speeds of 20mph.
Let’s get lost in a world made of books, coffee, and rainy days.
The wettest place in the world:
Mawsynram in the Maghalaya State of India takes the title for the wettest place in the world. Receiving an astonishing average of 11,971mm of rainfall every year – which compared to the UK’s 1,154mm average, is quite large.
Those are my strange facts for the day! Hope you enjoyed and possibly learned something new!!
