Not illustrated. 1896 edition. Excerpt: ...which is equivalent to considering the wind to have the same mean velocity for all directions. If directions are observed to sixteen points, half the number belonging to each extra point, should be added to the two octant points between which it lies; for example, NNE = 6 should be separated into N= 3 and. NE = 3; ESE = 4 into E = 2 and SE = 2. The result will be app1oximately identical with that obtained by using the complete formula for sixteen points. Table 4.8. Multiples of cos 45; form for computing the numerator and denominator. Table 49. Values of the mean diredion (a) or its complement (90--a). Table 48 gives products of cos 45 by numbers up to 209, together with, a form for the computation of the numerator and denominator, illustrated, by an example. The quadrant in which a lies is determined by the folio.wing rule: When the numerator and denominator are positive, a lies between JVand E. When the numerator is positive and the denominator negative, a lies between 51 and E. When the numerator and denominator are negative, a lies between 5 and W. When the numerator is negative and the denominator positive, a lies between N and W. Table 49 combines the use of a division table and a table of natural tangents. It enables the computer, with the numerator and denominator oi Lambert's formula (computed from Table 48) as arguments, to take out directly the mean wind direction a or its complement. The top argument consists of every fifth number from to 200. The side argument is given for every unit from i to 50 and for every two units from 50 to 150. Tabular values are given to the nearest whole degree. Rule for using the table: Enter the table with the larger number (either numerator or denominator) as the top argument. If the denominator...
