Adam Clarke on Job 36:27

He maketh small the drops of water - This appears simply to refer to evaporation, and perhaps it would be better to translate יגרע yegara, "he exhales;" detaches the smallest particles of the aqueous mass from the surface in order to form clouds, as reservoirs for the purpose of furnishing rain for the watering of the earth. God is seen in little things, as well as great things; and the inconceivably little, as well as the stupendously great, are equally the work of Omnipotence.

They pour down rain - These exceedingly minute drops or vapor become collected in clouds; and then, when agitated by winds, etc. many particles being united, they become too heavy to be sustained by the air in which they before were suspended, and so fall down in rain, which is either a mist, a drizzle, a shower, a storm, or a waterspout, according to the influence of different winds, or the presence and quantum of the electric fluid. And all this is proportioned, לאדו le-edo, "to its vapor," to the quantity of the fluid evaporated and condensed into clouds.
