13. the amount of moisture in the air
14. a condition in which visibility is so low that it is difficult to distinguish between the ground and the sky
17. a rainfall amount totaling less than 0.01 in, usually too little for a rain gauge to measure
18. water that is not absorbed into the ground because either too much rain has fallen or the ground cannot absorb it fast enough
