19 Abstract: AA statistical data summary of surface weather observation climatology:Moscow USSR. This summary is similar to the Revised Uniform Summary of Surface WeatherObservations (RUSSWO), but is based on data collected from limited-duty weather observingstations; i.e., those that take weather observations less than 24 hours a day, 7 days aweek. The summary is in five parts: PART 1, Weather Conditions and AtmosphericPhenomena; PART 2, Surface Winds; PART 3,Ceiling and Visibility; PART 4, PsychrometricSummaries; and PART 5, Pressure Summaries. Note that PART 2, Precipitation, is omitted.See USAflTAC/TN-83-O01 (AD132186), An Aid For Using The Revised Uniform Summary of SurfaceWeather Observations (RUSSWO), for complete descriptions of contents and instructions foruse. . -

WEATHER CONDITIONS AND ATMOSPHERIC PHENOMENA SUMMARIES

WEATHER CONDITIONS SUMMARY

1. A PERCENTAGE FREQUENCY OCCURRENCE SLMMARY OF VARIOUS ATMOSPHERIC PHENOMENA AND OBSTRUCTIONS TO VISION.

2. DATA BASED ON HOURLY OBSERVATIONS.

3. SUMMARIZED BY TE STANDARD 3-HOUR TIME GROUPS BY MONTH, MONTHLY AND ANNUALLY gALL YEARS COMBINED).

DEFINITIONS:

THUNDERSTORMS: ALL REPORTED THUNDERSTORMS. TORNADOES AND WATERSPOUTS.

RAIN AND/OR DRIZZLE: ALL REPORTED RAIN AND OR DRIZZLE FALLING TO THE GROUND BUT NOT FREEZING.

FREEZING RAIN ANDIOR FREEZING DRIZZLE IGLAZE): ALL REPORTED FREEZING RAIN OR FREEZING DRIZZLE.

SNOW AND/OR SLEET. SNOW INCLUDING SNOW PELLETS AND GRAINS, ICE CRYSTALS AND PELLETS. AND/OR SLEET (ICE PELLETS).

HAIL: ALL REPORTED HAIL.

ALL PRECIPITATION: THIS CATEGORY INCLUDES ALL OBSERVATIONS REPORTING PRECIPITATION. BECAUSE PORE TPAN ONE TYPE

KOF PRECIPITATION MAY APPEAR IN A SINGLE OBSERVATION, THE SUM OF THE PFRCENTAGES IN THE INDIVILUAL COLUMNS MAY

EXCEED THE PERCENTAGES IN THIS COLUM(N.

FOG: ALL REPORTED FOG, ICE FOG AND GROUND FOG.

SMOKE AND/OR HAZE: ALL REPORTED SMOKE, HAZE AND ANT COMBINATION THEREOF.

BLOWING SNOW: ALL REPORTED BLOWING SNOWS INCLUDING DRIFTING WHEN REPORTED.

DUST AND/OR SAND: ALL REPORTED DUST, SAND, BLOWING DUST, BLOWING SAND AND ANY COMBINATION THEREOF.THE ATMOSPHERIC PHENOMENA SUMMARY (DAYS WITH) INCLUDES ONLY THOSE REPORTS WHEN THE PHENOMENA

VISIBILITY LESS THAN Si MILES (C110 METERS).

ALL OBSTRUCTIONS TO VISION: INCLUDES ALL REPORTS OF OBSTRUCTIONS TO VISION (FOG THR OUST/SAND)AND BLOWING SPRAY. BECAUSE MORE THAN ONE PHENOMENA PER OBSERVATION MAY OCCUR. THE SUM OFTHE INDIVIDUAL COLUMNS MAY EXCEED THIS COLUMN.

NOTES:

1. A VALUE IN THE TABLES OF ".0" INDICATES LESS THAN .052 OCCURRENCE WHICH IS USUALLY ONLY ONE OCCURRENCE

2. METAR STATIONS (BEGINNING IN JAN 19681 AND SYNOPTIC REPORTING STATIONS RECORDED ON THEAWS FORMS 10/IDA AND TRANSMITTED LONGLINE ONLY IHE HIGHEST ORDER OF ATMOSPHrRIC PHENOMENA OBSERVED.

BEGINNING IN JAN 1970, METAB STATIONS RECORDED ALL OBSERVED PHENOMENA BUT CONTINUED TO TRANSMIT ONLYTHE HIGHEST ORDER. FOR EXAPPLE, IF THE OBSERVATION CONTAINED RAIN, FOG AND SMOKE, ALL THREE WILL

APPEAR ON THE AWS FORMS 1OOA. BUT ONLY THE RAIN WAS TRANSMITTED LONGLINE. THEREFORE ONLY THE RAIN

APPrARS IN OUR DATA BASE FOR HOURLY SUMMARIZATION. THIS PRACTICE EFFECTS THE PERCENTAGES IN THE TABLES.

DATA DERIVED FROM HOURLY DATA.

C. .PRESENTED ARE THE PERCENTAGE FREQUENCY OF MIND DIRECTION TO 16 COMPASS POINTS, CALM AND VARIABLLVERSUS MIND SPEED IN KNOTS IN INCREMENTS OF BEAUFORT CLASSIFICATIONS.

PERCENTAGES ARE SHOWN BY BOTH DIRECTIONS AND SPEED. AND IN ADDITION THE MEAN WIND SPEED IN GIVENFOQ EACP DIRECTION.

DATA PRESENTED BY THE STANDARD 3-HOUR TIME GROUPS BY MONTH, MONTHLY AND ANNUALLY IALL YEARS COMBIEDEOI..

A SEPARATE ANNUAL TABLE PRESENTS THE SAME BIVARIATE DISTRIBUTIONS WITH IMPOSED CEILING/VISIBILITYLIMITATIONS: NHEN VISIBILITIS EQUAL TO OR GREATER THAN 1/2 MILES, THE CEILINGS ARE 20C TO 1400 FEET AND/OR WHENTHE CEILING IS EQUAL TO OR GREATER TfAN 200 FEEI, TI-E VISIBILITIES ARE 112 THROIGH 2 1/2 MILES.

A PERCENTAGE VALUE OF ".0' IN THESE TABLES INDICATES ONE OR MORE OCCURRENCES AMOUNTING TO LESS THeAt. .05%.

DATA DERIVED FROM HOURLY OBSERVATIONS.

FREQUENCY DISTRIBUTION PRESENTED BY THE STANDARD 3-HOUR TIME GROUPS BY MONTH, MONTHLY AND ANNUALLY (ALL YLARS

COMBINEOI.

NOTES:

BEGINNING IN 1966, METAR STATIONS REPORTED VISIBILITIES TO 6 MILES AND GREATER THAN6 MILES. THEREFORE THE COLUMN FOR VISIBILITIES EQUAL 10 OR GREATER THAN 10 MILLS

APPEAR BLANK.

m . AS A RULE, AIRWAYS STATIONS NORPALLY REPORT VISIBILITIES TO 6 MILES AND 7 OR GREATER, HOWEVER

SOME STATIONS REPORT HIGHER VALLES. THEREFORE, THE 10 MILE VISIBILITY COLLMN SOMETIMES CONTAINSMALL PERCENIAGE VALUES. HOWEVER, T-ESE VALUES ARE OF LITTLE MEANING AND SHOULD RE

DISREGARDED.

FOR METAR CIVILIAN STATIONS REPORTING "CAVOR", ALL CEILINGS ABOVE So0 FEET WERE SUPPESSLD

TO SOC0 FEET. THEREFORE. NO PERCENT VALUES APPEAR ABOVE SOOD FEET.

SKY COVER SUMMARY

PRESENTS PERCENTAGES OF SKY COVER IN EITHER Ioti-S OF COVERAiE OR "AIRbAyS CLASSIFICA IONS".
