1. A PERCENTAGE FREQUENCY OCCURRENCE SUMMARY OF VARIOUS ATMOSPHERIC PHENOMENA AND OBSTRUCTIONS TO VISION.
2. DATA BASED ON HOURLY OBSERVATIONS.
3. SUMMARIZED BY THE STANDARD 3-HOUR TIME GROUPS BY MONTH, MONTHLY AND ANNUALLY (ALL YEARS CO-BINEDI.
ATMOSPHERIC PHENOMENA SUMMARY
1. A PERCENTAGE FREQUENCY OF DAYS SUMMARY OF VARIOUS ATMOSPHERIC PHENOMENA AND OBSTRUCTIONS
TO VISION.
2. DATA BASED ON SUMMARY OF DAY DATA.
3. SUMMARIZED BY MONTH WITH ALL HOURS AND ALL YEARS COMBINED.
DEFINITIONS?
THUNDERSTORMS: ALL REPORTED THUNDERSTORMS, TORNADOES AND WATERSPOUTS.
RAIN AND/OR DRIZZLE: ALL REPOPTED RAIN AND OR DRIZZLE FALLING TO THE GROUND BUT NOT FREEZING.
FREEZING RAIN AND/OR FREEZING DRIZZLE (GLAZEI: ALL REPORTED FREEZING RAIN OR FREEZING DRIZZLE.
SNOW AND/UR SLEET. SNOW INCLUDING S-NOW PELLETS AND GRAINS, ICE CRYSTALS AND PELLETS. AND!OR SLEET !ICE PELL
HAIL: ALL REPORTED HAIL.
ALL PRECIPITATION: THIS CATEGORY INCLUDES ALL OBSERVATIONS REPORTING PRECIPITATION. BECAUSE MORE THAN ONE
OF PRECIPITATION MAY APPEAR IN A SINGLE OBSERVATION, THE SUM OF THE PERCENTAGES IN THE INDIVICUAL COLUP
EXCEED THE PERCENTAGES IN THIS COLLMN.
FOG: ALL REPORTED FOG, ICE FUG AND GROUND FOG.
SMOKE AND/OR HAZE: ALE REPORIEU SMOKE . HAZE AND ANY COMPINATION THEREOF.
BLOING SNOW: ALL REPORTED BLOWING SNOWS INCLUDING DRIFTING WHEN REPORTED.
ULST AND/OR SAND: ALL REPORTED DUST, SAND, BLOWING OUST, PLOWING SAND AND ANY COMBINATION THEREOF.THE ATMOSPHERIC PHENOMENA SUMMArY (DAYS WIIt-I INCLLDES ONlY THOSE REPORTS 6FEN THE PHENOMENA
VISIBILITY LESS THAN ;18 MILES IT)LO METERSI.
ALL OBSTRUCTIONS TO VISION: INCLUDES ALL REPORTS OF O9STRUCTIONS TO VISION IFOG THRU OUST/SANDI
LAND BLOWING SPRAY. bECAUSE MORE THAN ONE PHENOMENA PER OSERVATION MAY OCCUR, THE SUMTAE INDIVIDC'AL COLLNS MAY EXCEED THIS COLUMN.
NOTES:
I. A VALUE IN THE TABLES OF ".0" INDICATES LESS THAN .0,% OCCURRENCE WHICH IS USUALLY ONLY ONE OCCURRENCE
Z, METAR STATIONS (BEGINNING IN JAN 19681 AND SYNOPTIC QEPORTING STATIONS RECORDED ON THEAWS FORS IC/SOB ANO TRANSMITTED LONGLINE ONLY THE HIGHEST ORDER OF ATMOSPHERIC PHENOMENA OBSERVED.
BEGINNING IN JAN 197D, METAR STATIONS RECORDED ALL OBSERVED PHETJOMENA BUT CONTINLED TO TRANSMIT ONLYTHE HIGHEST ORDER. FOR EXAMPLE, IF THE OBSERVATION CONTAINED RAIN, FOG AND SMOKE, ALL IREE WILLAPPEAR ON THE AwS FORMS 10/IDA, BUT ONLY THE RAIN WAS TRANSMITTED LONGLINE. THEREFORE ONLY THE RAINAPPEARS IN OUR DATA BASE FOR VOURLT SUMMARIZATION. TVIS PRACTICE EFFECTS THE PERCENTAGES IN THE TABLES.

CEILING VLRSUS VISIBILITY AND SKY COVER SUMMARIES
CEILING VFRSUS VISIBILITY SUMMARY
THIS SUMMARY IS A BIRVARIATE FREQUENCY DISTRIBUTION BY CLASSES OF CEILING FROM "0" THROUGH EQUAL
TO oR GREATER THAN 20,000 FLET AND AS A SEPARATE CLASS "NO CEILING", VERSUS VISIBILITY IN 16CLASSES FROM ZERO THROUGH EcUAL TO O GREATER THAN 10 MILES.
DATA DERIVED FROM HOURLY OBSERVATIONS.
FREQUENCY DISTRIBUTION PRESENTED BY THE STANDARD 3-HOUR TIME GROUPS BY MONTH, MONTI-LY AND ANNUALLY IALL YEAR'
CoMAINFO),
NOTES:
bEGINNING IN 1968, METAR STATIONS REPORTED VISIBILITIES TO 6 MILES AND GREATER THANb MILES. THEREFORE TPL COLUMN FOR VISIBILITIES EQUAL T
0 OR GREATER TI-AN I0 MILLS
APPEAP BLANK.
AS
A RULE, AIRWAYS STATIONS NORMALLY REPORT VISIBILITIES TO 6 MILES AND 7 OR GREATER, H0WFVER
SOME STATIONS REPORT HIGHER VALUES. THEREFORE, THE I0 MILE VISIBILITY COLUMN SOMETIMES CONTAIN
SMALL PERCENTAGE VALCES. HOWEVER, THESE VALUES ARE OF LITTLE MEANING AND SHOULD PE
DISREGARDED,
FOR METAR CIVILIAN STATIONS REPORTING "AVOK", ALL CEILINGS ABOVE SOO' FEET WERE SUPPESSEn
T0 50CO FEET. THEREFORE, NO PERCENT VALUES APPEAR ABOVE 5000 FEET.
SKY COVER SUMMARY
PRESENTS PERCENTAGES OF SKY COVER IN EITHER IoTHs OF COVERAGE OR "AIRWAYS CLASSIFICATIONS".
DATA SUMMARIZED BY THE STANDARD I-POUR TIME GROUPS BY MONT1, MONTHLY AND ANNUALLY TALL YEARS COMBIKEDI.
ALSO PRESENTED ARE MEAN SKY COVERS.
