Anemoscope (G r. wind, and to look), a wind indicator, or weathercock. The term is, however, only applied when the weathercock is attached to a spindle which passes from the vane into an apartment below, and there by an index upon a compass dial indicates in what direction the wind blows. For expressing this direction the plan has been adopted of dividing the great circle of the horizon into 32 parts of 11° 15' each, and calling the directions of the wind successively: X., X. by E., N. X. E., X. E. by X., N. E., N. E. by E., E. X. E., E. by X., E., E. by S., E. S. E., S. E. by E., S. E., S. E. by S., S. S. E., S. by E., S., S. by W., S. S. W., S. W. by 8., S. W., S. W. by W., W. S. W., W. by S., W., W. by X., W. X. W., X. W. by W., X. W., X. W. by X., X. X. W., X. by W., X. The latest improvement of the anemoscope is to attach a recording clockwork to the dial plate, so that not only the direction of the wind, but the time that it blows in any direction, is permanently recorded.
Such an arrangement is now in operation at the meteorological observatory in the Central Park, New York.
