PHOTOLYSIS (PHOTODEGRADATION OR PHOTODISSOCIATION) OCEAN WATERS
this is the decomposition of the water molecule into hydrogen molecule (H2) and oxygen atom (O) under the effect of solar radiation, namely Ultraviolets, X and gamma are usually involved in such reactions.
In other words this is the decomposition of a body by the light (H2 = 2/29 = 0.06) and (O = 16/29 = 0.55), both lighter-than-air (29 / 29 = 1), they are driven by the currents of hot and dry air
SYNTHESIS OF WATER IN THE ATMOSPHERE (RAIN)
The hot air with H2 and O enters high in the cold air and forms a kind of balloon, cold air and pushes the covers from all sides, it compresses and at favorable rates triggers combination of the two gases in a real explosive chemical reaction (H2 and O mixture is explosive), rainwater born. http://www.commentfaiton.com/fiche/voir/53112/comment-comprendre-la-synthese-de-l-eau
We wrote: H2 + O ----------> H2O (= explosion and thunder and lightning)
The light of the flash reaches us first (speed of light 299, 792, 458 m / s)
Then the sound of the explosion (thunder) (speed of sound 340 m / s therefore lower than that of the light)
Then the rain (speed falls drops of water is lower than that of light and sound)
So: flash + thunder + rain = one operation.
