It’s a somewhat cloudy day. You figure a storm will be coming and then raindrops start to fall. This doesn’t register as abnormal until you hear a small thud on the ground. Then you see a frog, limbs quivering, writhing on its back. Before you can figure out what has just happened, more frogs are falling around you. In fact, thousands of frogs are falling. If you think such an event could only happen in ancient times, you’d be wrong. It’s Brignoles, France and the year is 1977!

Although it hasn’t been observed or tested scientifically, frogs have been recorded as falling from the sky since A.D. 77. The most recent episode took place last year in Bromley, England, and before that in Serbia in 2005 and London in 1998. This anomaly, not exclusive to frogs, has occurred with salamanders, fish, mussels, worms, lizards, and various parts of these animals. But how can so many animals, that aren’t common to a certain area, just fall from the sky? Well the answer may be more simple than you think.

Throughout the ages, most people have associated falling frogs with the weather. André-Marie Ampére, a famous French Physicist, proposed a hypothesis about falling frogs at the turn of the 19th century. He said to the Society of Natural Sciences that frogs and toads, which were more populous in the countryside, could be lifted by violent winds and carried great distances. This would definitely explain why these and other falling animals weigh little and are often small.
Recently, scientists have been recognizing the power and possible influence of water spouts in these strange events. Water spouts, tornadoes over water, can pick up objects caught in their center and carry them great distances. If you think of what tornadoes can do to various objects, including us, water spouts do seem a logical explanation. So the next time you’re looking to buy a new umbrella, you may want to choose a stronger one. Trust me, it will be worth the extra few bucks.

It's about toads.

It happens when a mini-tornado passes over water and sweeps up objects including animals.
If the creature is lightweight, like a fish or a small frog, it may be caught in a strong storm or a cloud updraft for a long time rising higher until it is thrown out like a hailstone.
It happens because of the dynamics of the atmosphere. When there is a convection current of air beneath a cloud, it can draw objects upwards. I've heard of fish, frogs, crabs and flies (they quite often die in the process.)
God quite liked using them in plagues and they might even drop in when the end of the world is nigh. So if a frog lands on your head start being nice.

Yep, It's like that red rain ( ---blood-red rain :)
Coming from red sand/earth (deserts?) blown over the oceans to Europe and elsewhere.
Did you know that 'convection' is like our Earth breathing?
It lifts up small organisms over the sea primarily (land too ?) in the air and 'replant' it elsewhere.
A very cool and poetic fact :)

Oo-er... it's getting misty - I'd better turn on my froglights.
Sadly, there are very few true amphibian puns, so it's just not worth stressing out and making yourself eel over it.

Very good indeed [;D]
If this were a chess match, I might have to use the Caecilian defence.

Back in a tad. Pole's are coming from Warsaw.

I went to have a look at Beachy Head recently, and drove there via Eastspawn.
