Tornado and Cyclone.

The government weather bureau has sent out the following distinction, so that all irf<jta’ know the difference between these)two forms of atmospheric disturbance: The tornado is a sudden outburst of wind In an otherwise quiet, sultry atmosphere; it is ushered in by a loud. Indescribable roar, similar to a continuous roll of thunder; Its path is very narrow—seldom more than S(MJ feet xvide at greatest destruction; it moves generally from southwest to northeast, and rarely extends more than 20 miles; it very often rises in the air, to decend again at a point a few miles ahead; it Is always accompanied by thunderstorms, with ofte’. a bright glow iu the cloud; the cloud has usually a funnel shape, which appears to be whirling, though some observers have described Its appearance as like that of a huge ball rolling forward. A tornado may be considered as the result of an extreme development of conditions which otherwise produce thunderstorms. A cyclone, on the other hand, is a very broad storm, oftentimes 1,000 miles in diameter, and sometimes can be followed half around the world; the winds circulate about It from right to left, or the way one turns clock hands backward (in the Southern Hemisphere this motion is reversed). The air pressure always falls as one approaches the center, where at sea, there is often a calm, xvith clear sky visible at times. The cyclone winds often rise to hurricane force, but are not to be compared with the extreme violence of the tornado, before which the most solid structures are razed.
