Book Description
Excerpt from Report on the Calcutta Cyclone of the 5th October 1864 To those who are accustomed to the accurate and minute Observations of European Observatories, and who know how much the value of meteorological observations depends on the careful comparison of instruments and elimination of instrumental errors, and on the training and experience of observers, it may seem almost wasted labour to attempt to deduce any results from Observations made in many cases by unpractised Observers, with uncompared instruments, and from such guesses at the direction and force of wind currents as can be made by persons in their own houses, unconscious of eddies, and judging from a general knowledge of the compass bearings of the place. But these are, for the most part, all that are obtainable in India, and had they been rejected, little would have remained but one or two of the Ship observations, those of the Government Observatories at Calcutta and Madras, and those furnished by Mr. R. H. Barnes from Ceylon. The Calcutta Observations, moreover, were recorded continuously, or at ten minute intervals, dur ing the earlier part of the storm only, being then intermitted, partly owing to the destruction of the self-registering instru ments, partly to the observers having left the observatory building, under apprehension of its destruction by the storm; a catastrophe which at one time appeared imminent.
