Meteorology [true/false] 1) full-scale fog collectors are complex, flat, circular nets of nylon supported by a post at either end and arranged parallel to the direction of the prevailing wind. 2) the air behind a cold front is noticeably colder and drier than the air ahead of it. when a cold front passes through, temperatures can drop more than 15 degrees within the first hour. 3) if you see a tornado and it is not moving to the right or to the left relative to trees or power poles in the distance, it may be moving towards you. 4) tropical moist climates are the most common climate on land masses. 5) as water collects on the net while fog harvesting, the droplets join to form larger drops that fall under the influence of gravity into a trough or gutter at the bottom of the panel, from which it is conveyed to a storage tank or cistern.
