PART D CEILING VERSUS VISIBILITY

This summary is a bivariate percentage frequency distribution by classes of ceiling from zero to equal to or

greater than 20,000 feet and as a separate class ceiling, versus visibility in 16 classes from zero toequal to or greater than 10 miles. Data are derived from hourly observations, and three sets of tables are

presented as follows:

1. Annual - all years and all hours combined2. By month - all years and all hours combined3. By month - by standard 3-hour groups

Due to the cumulative nature of this presentation, it is possible to determine the percentage frequency of

occurrence for any given limit of ceiling or visibility separately, or in combination of ceiling and visi-

bility. The totals progress to the right and downward. Ceiling may be determined independently by re-

ferring to totals in the extreme right hand column. Also, visibility may be determined independently by

reference to the horizontal row of totals at the bottom of the page. The percentage frequency for which thestation was meeting or exceeding any given set of minima may be determined from the figure at the intersection

of the appropriate ceiling column and visibility row. Several exatities in the use of these tables are shownon pages 2 and 5 below.

U. S. Weather Bureau end Navy stations did not report ceilings within the range 10,000 feet and higher prior to

January l9h9. Summaries prepared from data for these stations using the earlier period and data subsequent

to January 1949 %ill be modified to limit ceilings to 10,000 feet. Short periods of record prior to 1949

for these stations will be eliminated from the summary. For Air Force stations, the "no ceiling" categoryincludes clear and scattered conditions, and ceilings above 20,000 feet for period through June 191.8.

Beginning in July 1948 for Air Force stations and January 1941' for USWB and U. S. Navy stations the "noceiling" category consists of observations with leso than 61/i total sky cover and those cases where total

sky cover i 6/10 or more, but not more than 1/2 of the si'.y cf)vcr in opaquc.

Beginning in Jsnusr, 1968, M4TAR stations report visibilitiesi to 6 miles and then greater than 6 miles.

Thus, for ME-AR stations, the category equal to or greater titan 10 miles is not printed in the tables,

unless the summary was for a period ending before January 196. For most Airways stations, visibilities of

qreater than 7 miles were not reported for part of the period of record. Therefore, the >10 mi visibility category

should be used with great caution.(*ont ifud on [reverse Side

EXAMPLE # 4 Values below mininums stated in the table may be obtained by subtracting the value givenin the table from 100%.Thus, to obtain the percentage of observations with ceiling < 1500 feet and/or visibility< 3 miles, subtract the value read from the table at the intersection, which is 91.0,from 100.0. The answer 9.0 is the percentage of observations with ceiling < 1500 feetand/or visibility < 3 miles.

Likewise, the percentage of observations with ceiling < 500 feet and/or visibility < Imile is 2.6, obtained by subtracting 97.4 from 100.0.

EXAMPLE # 5 To find the percentage of observations falling within the two categories given in exampleabove, subtract the value read from the table for the first set of limits from the valuein the table for the second set of limits. The difference will be the percentage ofobservations meeting the lower set of limits, but not meeting the higher set of limits.

The value 91.0 read from the table at the intersection of > 1500 feet with > 3 miles,subtracted from 97.4 read from the table at the intersection of > 500 feet with > 1 mileis equal to 6.4%. Thus; 6.4 percent of the observations meet the criteria: "ceiling >500 feet with visibility > 1 mile, but < 3 miles; or ceiling _500 feet, but < 1500 feetwith visibility > 1 mi.e. r

Since these tabulations are prepared in several ways including by month, by 3-hour groups it is possibleto determine diurnal variations of ceiling and visibility limits as well as probabilities of variousceiling-visibility combinations.

PART E PSYCHROMETRIC SUMMARIES

In this section are presented various suakories of &ry- end vet-bulb temperatures, dew points, and relativehumidity. The order and wanner of presentations follows:

1. Ctmul.tlve Percentse frequency of occurreuce - derived from daily observations and presented by monthand nrnr-nl for nil yeutrs -combined. These tabulations provide the cumulative percentage frequency toteaths of tempernture by 5-deee Fahrenheit in-rements, plus menu temperature, standard deviations, andtotal numbhr of observa.tions in three separate tablcs as follows:

a. Daily naximu temperaturesb. Daily minitmim tewperaturesc. Daily mean temper-itures

OTE: Beining In January l964, daily maximum and minimum temperat,%reR are routinely selected fromhourly observations rtcorded on surface observing forms or from automated data collections for allAir Force operated stations. For those stations observing less than 24 hours per day, and where maxi-

mum and minimum temperatures are required but not recorded, these are also selected from hourly datafrom an early e January 1949 and later. Please refer to notations on sugmary pages and Station Historyfor further inforration on reporting practices of individual stations.

2. Extreme values - derived from daily observations with the extreme value selected for each year and month ofrecord available. An annual (ALL MODNT9r) valie is selected when all months for a year have valid extremes.

Means and standarl deviations are computed for months and annual when four or more values are present for

any colvan. Two tables of daily extremes are prepared:

a. Extreme maximum temperatu-b. Z.xtreme ainkausm temerature

NOT: The following symbols are used in the extreme data blocks|

(1) * indicates the extreme van selected from a month with one or more days missing.

(2) indicates the extreme was selected from a month in which hourly temperatures were availablefor less than 24 hours for at least one day in the month.

3-n1m = m

3. Bivariate percentage frequency di b o and computations of versus wt-bulb rature.This tabulation is derived from hourly observations and is presented by month and annuM all ho1 andyears combined. The following informatiou is provided.

a. The maln body of the summary consists of a bivarlate percentage frequency distribution of vet-bulbdepression In 17 classes spread horizontally; by 2-degree Intervals of dry-bulb temperature spreadvertically. Also provided for each of the dry-bulb Intervals is the percentage of observations withdry-bulb and vet-bulb temperature combinedj and again for dry-bulb, vet-bulb, and de-point tempera-tures separately. Total observations for these four item is also provided in two lines at end ofeach tabulation table, which ny be continued on several pages.

NOT% A percentage frequency In this table of ".0" represents one or more occurrences amounting toless than .05 percent.

b. Statistical data for the ndividual elements of relative humidity, dry-bulb, vet-bulb, and de-pointtemperatures are shown in the section at the, bottom left of the form. These consist of the sum ofsquares (iX2 ), sums of values ( 'X), means (X), and standard deviations (Ox). The number of obser-vations used in the computation for each element is also shown.

a. At the lover right of the form are given the mean number of hours of occurro wv for six ranges ofdry-bulb, vet-bulb, and dev-point temperatures, and total number of houra Vw*V.le n " periodrepresented. Mean number of hours is shown to tenths and indicates mean ster of homums per yearin the annual summary, or ean number of hours per month In the tabulation by mrath.

NTE: Wet-bulb temperature usually was not reported prior to 1946. Relative humidity usually wasnct reported prior to 1949, nor subsequent to June l958j and was co ted by machine mathodsfor observations recorded during these periods. All values of de-point temperature andrelative humidity are with respect to water, unless otherwise Indicated.

4. eans and standard deviations - These tabulations are derived from hourly observations and present themean, standard deviation, and total number of observations for the eight standard 3-hour groups, by monthand annual and again at the bottom for all hours combined. Records for all years combined are presentedin the following three tables; DRY-BULB TEMPERATURE, T-BULD TE(PEPATURE, and DEW-POINT TE P TURS.

5. Cumulative perceutae frequency of occurrence -f r&'1qt1.we humidity - This sumeary is derived from hourlyobservations and presents the cuZlative percentage frequency at occurrence of relative humidity byncrements of 10% classes, plus the mean relative humidity and total number of observations in two tables.

a. Table 1 is prepared by month and annual, all years combined, with month being the vertical argument.

b. Table 2 Is prepared by month by standard 3-hour groups, with the hour groups being the verticalargument and a separate page for each month. All years are also combined for this summary. ,

Presented in tis part are two tables giving the means, standard deviations, and total number of observationsof station pressure and sea-level pressure by month and annual for the local hourly observations correspondingto the eight 3-hourly synoptic times GCT. The same computations are also provided at the bottom of the pagefor all hours combined. All years of data available are combined in both of these tables, although the overallperiod is limited by service as indicated below.

NOTES: Station pressure not reported for all services until late in 1945.Station pressure reported only at 6-hourly times for Air Force stations from Jan 64 - Jul 65.METAR stations do not report Sea-level pressure for the period Jan 68 - Dec 70.

i. Station pressure is presented in the table in inches of mercury.

2. Sea-level pressure is presented in millibars. DATA NOT AVAILABLE

Provided below is a scale to convert station pressure values in inches of mercury or millibars to pressure-altitude in 1000's of feet. This scale is an enlarged model of the pressure-altitude scale in the SmithsonianMeteorological Tables.
