Leaving a Track. Scientists generally agree that CAT occurs when a stream of fast-flowing air passes through an air mass moving at a lower velocity or in the opposite direction. The resulting shearing action produces turbulence-often severe-at the boundaries of the stream. CAT is usually encountered near the constantly shifting west-to-east jet stream and near mountain ranges, where cold air frequently spills at great speed down the leeward slopes. Although the turbulence is obvious to any pilot caught in it, it cannot be seen by the human eye. Attempts to detect CAT with devices that...
...CAT apparently does leave a track. Turbulence tests conducted by NASA and the Federal Aviation Administration indicate that there may be a significant temperature difference between the air masses on either side of a wind shear. To scientists at North American Aviation's autonetics division, these findings seemed to provide an answer. Wherever there are sudden temperature variations in clear air, they surmised, there must also be CAT...
Commercial fishermen now take about 50 million Ibs. of the plentiful alewives from Lake Michigan each year, for processing into fish meal, fish oil, and cat and chicken food. Worried fed eral and state agents have stocked the lake with 2,000,000 steelhead trout and 300,000 coho salmon, hoping that they will take to an alewife diet and proliferate, thus bringing the ecology of the lake back into balance...
...football field was cleared for farming. "Our machines are kind of dramatic," allowed Blackie, and the 50 other spectators could only agree. On hand for a three-day land-development conference sponsored by the Peoria-based company, they were witnessing the kind of prowess that has made Cat a $1.5 billion-a-year operation and the world's biggest manufacturer of earth-moving equipment...
...consulting engineers and World Bank and United Nations representatives, lay Caterpillar's high-minded-and shrewd -concern with the plight of developing nations, which must start clearing their underdeveloped land if they are to meet the food needs of their burgeoning populations. Dramatizing the role it can play, Cat recently completed a test project in Costa Rica demonstrating that modern equipment can clear the densest jungle thicket for about $50 an acre; with older methods, the cost can run as high as $500. Beyond immediate clearing jobs, Caterpillar can expect to reap long-range benefits from seeing foreign countries...
