M., \\ ASSISTANT PKOFESSOR, SIGNAL OFFICE. WASHINGTON, D. C. 1888. ft PRINTED BY THE REGISTER PUBLISHING COMPANY, ANN ARBOR, MICHIGAN. 1 3706 1 PREFACE. The only complete collection of meteorological tables is that of Guyot r first published by the Smithsonian Institution in 1852. This has been enlarged in successive revisions until the 212 pages of the original work have grown to 738 in the fourth edition, forming a very valuable compi- lation of all the more important meteorological and physical tables in use since 1850. This last edition leaves nothing to be desired from a historical stand-point, but the working meteorologist still lacks a collection of the best tables, in compact form, convenient for use, and at small cost. The tables now presented have been in constant use by the author, and their present form is the result of many years' experience in the application of various tables. They are published, not to supersede the earlier and more extended collection, but as a convenient hand-book. In the general plan of the work, the main points to be noted are as follows : 1. As far as possible, all tables relating to the same subject are placed together. 2. All similar tables are united. Thus, the three tables for convert- ing millimetres to inches, on pp. 200, 225 and 258 of Guyot 1 form Table XXXII of this collection. In addition to compactness and ease of reference, this gives a table for all conversions needed, while previously there has been published no single table that will convert barometrical observations at the highest stations, e. g. Pike's Peak. 3. Only one table is given for each computation. For barometric hypsometry, in place of Guy of s seven tables in both English and French measures, only one is given in each, the best and most convenient, as found by six year's constant use of various tables. 4. Only tables needed for current meteorological work are included. J A11 references to Guyot are to 4th ed., Wash., 1884. TEMPERATURE TABLES. IV Thus, tables for converting Beaumur temperatures, Eussian half lines, etc., are omitted, because needed to-day only for the reduction of old observa- tions, and this rare use can well be supplied by Guyot. 5. The latest determination of the metre is used in all linear tables. The old length of the metre, 39.37079 in., has been used thus far, in all tables in this country and abroad, the usual argument being the inadvisa- bility of a change previous to an authoritative determination. But the length of the metre is now known so closely that the outstanding correc- tion can affect none of the values in our tablgs, while the old length, when the tables are carried to .001 in. (p25 mm 4/introduces afoaoorly oonotant A error of .001 in. The length adopted is 39.3702 in., for which determination I am indebted to Professor W." A. Eogers, of Bowdoin College, who is .con- fident that the true value lies between 39.37015 and 39.3702 in. An error of .0001 is hardly possible, and as the change of .0006 from the old value makes a change of only .001 in. in the conversion, it is clear that any pos- sible outstanding error is far within the tabular values. A table computed on the new length will require no modification in the future. 6. Several new tables are introduced. At the head of each table, or in its introduction, the authority is stated. If the table be new, i. e., recomputed or never before published in this form, it is marked ("Orig- inal "); if copied or enlarged from Guyot or any other author, the source / . is given. 7. At the end of the volume are given plates showing the distribution of the more important meteorological elements for the United States. I gratefully acknowledge the great assistance rendered me by Mr. C. J. Sawyer in the final arrangement of the hand-book. H. A. HAZEN. WASHINGTON, D. C., August 7, 1888. CONTENTS.

For the metrical tables, those of Angot are copied, with the single omission of the part relating to the moisture contents of the air column. REDUCTION TO SEA-LEVEL. The above remarks relative to vapor pressure apply as well to these tables. A strict application of the formula requires a correction for the observed pressure, but experience has shown that, assuming the mean temperature of the air column to be the mean of that at the base and summit, the correction for observed pressure vanishes. 1 If a gravity correction be desired, it may readily be found by Table XIV. In practice, it will be best to draw up a table for the single eleva- tion of the station, and for each two degrees, if the height be above 1,000 feet. The temperature to be used is an approximate mean for the previous 24 hours. If observations are made at equal intervals three times each day, the mean of the three, including the current observation, is to be taken. The metrical tables are computed in the same manner as the English. l Am. Journ Sc., New Haven, 1881, XXI, 366; XXII, 3. 21 vrn-xvi. PRESSURE TABLES. TABLE X.

These were from unventilated psychrometers. The second and third columns under " balloons " are the results with a sling psychrometer in balloon voyages on June 17, 1887, at St. Louis, and on August 13, at Philadelphia. The results in the latter cases were very satisfactory, agreeing at the same height in the ascent and descent. 53 XVII-XXIII. HUMIDITY TABLES. TABLES XX AND XXI. WEIGHT OF VAPOR. INTKODUCTION. It is often necessary to determine the weight of vapor in air having various percentages of humidity. The simplest method is based on the principle that the quantity of vapor is constant at any given dew-point, whatever may be the relative humidity of the air. Hence, the dew-point being given, we may immediately obtain the weight of vapor by these tables. The dew-point, if not given, may be found from the wet and dry bulb temperatures by Table XXII or XXIII. EXAMPLE. Let the air temperature be 55, and the wet bulb temperature 44. From Table XXII, we find the dew-point 30, and from Table xfe, with dew- point 30, the weight of vapor is 1.969 gr. XVII-XXIII. HUMIDITY TABLES.

HUMIDITY TABLES. TABLES XXII AND XXHI. DEW-POINT AND RELATIVE HUMIDITY. INTRODUCTION. For nearly one hundred years, a convenient method of determining the moisture contents of the air from readings of the wet and dry bulb ther- mometers has been sought. The main difficulty in all discussions has been the lack of ventilation of the wet bulb. The simplest form of expression is that of Regnault 1 as follows: x = f a (t t ') p., in which, x = the vapor pressure at the dew-point; / = the vapor pressure at the wet bulb temperature; t = the observed (C.) temperature of the air; V = the observed (C.) temperature of the wet bulb; p = the pressure of the air; a = a constant to be determined by experiment. The value of a, as determined by different experimenters, has ranged from .00084 to .00067. The larger value from un ventilated readings, and the smaller by means of the sling psychrometer. A long series of experiments by the author 2 has shown that the latter value is satisfactory. Assuming p = 29.4 and, a = .000673, the formula becomes x=f.011(t t / ), which is easy for computation in English measures. The above formula has received a marked confirmation by the experi- ments of Dr. A. Sprung with an Assman aspiration psychrometer. The results are given in " Das Wetter," Vol. V, p. 105, and show the same value of the constant adopted here. We may feel assured that this formula is 1 Compt. Bend., Paris, 1845, xx, 1127, 1220; 1852, xxxv, 930. 8 Am. Met. Jour., Ann Arbor, 1885, i, 342, 396. 56 XVII-XXIII. HUMIDITY TABLES. exact, and the table may be used for all properly ventilated psychrom- eters. The following formula has been deduced by Professor Ferrel from a long series of observations with the sling psychrometer at Colorado Springs and Pike's Peak by Professor Marvin: x = f- .000367 (t-n p 1 The temperature is in (F.) degrees. Substituting, p = 29.4, we have, for t t'= 10, x=f .011 (t V\ which agrees with the above formula in all cases except when the air is very dry, and even then the difference seldom amounts to 1 in the computed dew-point, which is far within the accuracy of vapor pressures used. While these tables apply strictly only to sling or ventilated psychrom- eters, yet they will be but slightly in error for all shelters of fair exposure. Kegnault's original formula contained a slight modification for readings of the wet bulb when covered with ice, based on a theoretical difference in evaporation. Experiment, however, has shown that there is no difference in the results, whether the bulb be covered with ice or water, and no change has been introduced in these tables. The tables have been computed for a constant barometer reading of 29.4 in., as the average air-pressure at the majority of stations in this coun- try. It will be found that, up to 3000 feet the errors incident to the use of the psychrometer are much greater than will justify a correction for press- ures differing from 29.4 in., but either Part II or III of the table will enable one to apply this refinement, if desired. It will readily be seen, from the construction of the table, that, if there be given the dew-point from Eegnault's condensing hygrometer, and the air-temperature, the relative humidity may be deduced without difficulty. EXAMPLES. Given, t = 65; t' = 50; then t t'= 15. From Table XXII, with the above values, we find; dew-point = 34, and relative humidity = 31 per cent. Given, t = 65, t' = 55, p = 26". Table XXII gives dew-point 47. 57 XVII-XXIII. HUMIDITY TABLES. *, From Table XVII, the vapor pressure for dew-point 47 = .322; the cor- rection of this from Table XXII, Part II, f or i t' = 10 and p = 26" is -h .013. Table XVII, with vapor pressure = .335 gives dew-point = 48. Table XXII, with air-temperature = 65 and dew-point = 48, gives relative humidity = 54 per cent. This correction to the dew-point for pressure, may be found much more readily from Table XXII, Part III, as follows: Given, t = 65, t 1 = 55, p = 26". The dew-point = 47, as before; Part III, with air-temperature 65, pressure = 26", and t t r = 10, gives correction = 1; hence, dew-point corrected for pressure = 48 D , as before. RELATIVE HUMIDITY FROM CONDENSING HYGROMETER. Given, t = 65; dew-point = 40; we have at once, relative humidity = 39 per cent. While these tables are extended to 40 F. and below for the dew- point, yet it should be borne in mind that we have no experimental vapor tensions below 22 F., but the tables are computed on extrapolated values from the formulae. A series of experiments in the Northwest in winter extending Eegnault's work 20 or 30 degrees lower would be of great value. 58 XYII-XXIII. HUMIDITY TABLES. TABLE XXII.

TABLE XXIV. LAMBERT'S FORMULA FOR THE DETERMINATION OF MEAN WIND DIRECTION. INTRODUCTION. Lambert's formula for the 8 principal wind directions is as follows: Tan A _ E. W. -f- (N.E. S.W.) cos. 45 + (S.E. K.W.) cos. 45 N". S.+ CST.E. S.W.) cos. 45 (S.E. K.W.) cos. 45 in which N., N. E., etc., represent the number of times the wind has blown in each octant during the period under consideration. We assume that the wind velocity is the same from all points. If directions from 16 points are observed, half of each extra point should be added to the direction preceding and following; for example, with N. N. E. 6, N. E. 5, E. N. E. 3, E. 2, E. S. E. 4, we would enter the formula with N. E. 9.5, E. 5.5, etc. The result will be almost identical with that from the full formula of 16 points. The table is in two parts: part I gives the product of any number with cos. 45 (.7071), and part II the value of the angle or its complement, in degrees. For the computations, the following form should be used: abcdefghik 1 m n opqrs part II angle E W N SNE SW SE NW e-f g-h i cos. 45 kcos.45 a-b 1+m c-d 1-m o-fn p+q f^ ( S 212202^13 9* 10 4 -10 2.8 -7.1 -10 -4.3 -5 9.9 -14.3 4.9 19 N. 71 W. r The signs of give the quadrant, s r s If the fraction or is not less than j$$, divide both numerator and s r denominator by any number till the values of r and s are found within part II. Always enter part II with the smaller number as the horizontal argument. If s be smaller than r, take the complement of the angle, as found in the table. 74 XXIV-XXX. WIND TABLES. In the use of this table it will be found that the larger the figures, pro- vided they are under iH, the easier the computation. For example, sup- r -18 pose . In the table there is no 18 opposite 14, but if we s 14 multiply the fraction by 5 we have U, and the corresponding angle from part II is 38, or taking the complement, since s is less than r, we have N. 52 W. The same result is attained if we multiply by 10. TABLE XXIV.-LAMBERT'S FORMULA.. (Original.) PART I. Multiples of Cos. 45.

WIND TABLES. TABLE XXVII. CONVERSION OF WIND VELOCITY IN MILES PER HOUR TO PRESSURE IN POUNDS PER SQUARE FOOT. INTRODUCTION. In many investigations it is necessary to express the velocity of the wind in terms of the pressure, but the determination of this relation is difficult, and the problem has attracted the attention of physicists for a hundred years. Of the various results, those of Bouse, quoted by Smeaton 1 seem most consistent with recent investigations 2 . The formula, as announced by Smeaton from Rouse's experiments, is: p = .005 v* .s, in which p = the pressure in pounds; v = the velocity in miles per hour; s = the surface in square feet. The table has been computed from this formula, s being taken as one square foot. It will be understood that the table is strictly applicable only to sur- faces of about one square foot, and for velocities from twenty to forty miles per hour.

To Find Local Time of Greenwich Noon in Longitude 49 26' West of Greenwich. Look for degree of longitude 49 and we find 8 A. M at the head. 26' of longitude in the center table gives opposite 49: 42 ; hence local time of Greenwich noon in longitude 49 26' W. is 8:42 A. M. To Find Greemvich Time of Local Noon in Longitude 95 40' W. Greenwich noon = 5:37 A. M. Subtract 5:37 from 12, and we have 6:23 p. M., Greenwich time of local noon. To Find Local Time of Any Greemvich Time. Find 2:35 p. M. Greenwich time in longitude 111 35' W. Greenwich noon 4:34 A. M. local time. 2:35 p. M. Greenwich time would be 2 hours 35 minutes later, or 7:9 A. M. local time. To Find Greenwich Time of Any Local Time. Find Greenwich time of 4:37 P. M. local time in 98 8' longitude W. Local time of Greenwich noon = 5:27 A. M.; 4:37 p. M. is 11 hours 10 minutes later, or 11:10 p. M^ Greenwich time. To use this table for any other meridian than Greenwich, substitute for "Greenwich noon" its time at the meridian desired. Given 7 A. M. Eastern Time, to find its Local Time in Longitude 112 48' W. Over 112 we find 4, and opposite that for 45' we have 29. Hence 7 A. M. (Eastern) = 4:29 A. M. (local) in longitude 112 48' W. 112 XXXVII-XLV. MISCELLANEOUS TABLES. XXXIX.-TIME OF SUNRISE.

MISCELLANEOUS TABLES. TABLE XL. TO DETERMINE THE POSITION OF A POINT ON A MAP. INTRODUCTION. This table is designed to facilitate the determination to minutes of arc, of positions on a map with lines of latitude and longitude, having given the shortest distances on the map from the point to the nearest parallel and meridian. For use, first measure on any convenient scale the distance between any two lines of latitude or longitude. If no figure at the top of the table coincides with this distance, it may be multiplied or divided by any number to bring it within the range of the table. Then measure the distance on the~same scale from the point to the line of latitude or longi- tude and find the"same number multiplied or divided as above, if necessary, in the left-hand column. The intersection of lines from these two numbers will give the minutes^of latitude or longitude on the map. EXAMPLE.

MISCELLANEOUS TABLES. TABLES XLI-XLIII. DIVISION TABLES. INTEODUCTION. These tables are designed to facilitate division by 28, 29 and 31 : divisors of frequent use in meteorological reductions. The horizontal rows of figures lettered "D" in plain and bold-faced type are respectively the first three and last two figures of the dividend. The corresponding numbers in the horizontal rows lettered " Q " are respect- ively the hundreds, tens and units figures of the quotient. EXAMPLE. TABLE XL^" To divide 22883 by 28: Under 228 in the horizontal rows (D) we find 8, and under 76, the number nearest to 83, in bold-faced type, we find 17. Hence the quotient is 817^V. 116 XXXVII-XLV.
