BY RAIN
WHILE THE JULY RAIN WAS PERHAPS SOMEWHAT OVERSHADOWED EPISODES IN PREVIOUS MONTHS, THE WINDY WEATHER CERTAINLY CAPTURED THE HEADLINES DURING THE MONTH,
ACTIVE SOUTHWEST MONSOON BLEW FOR NEARLY A WEEK IN EARLY JULY AND WAS FOLLOWED BY THE SUCCESSIVE PASSAGES OF THREE TROPICAL CYCLONES, ONE OF WHICH PROMPTED THE HOISTING OF THE NO. 8 GALE OR STORM SIGNAL ON JULY 22.
MOST OF THE MONTH'S RAINFALL WAS ASSOCIATED WITH THESE WEATHER SYSTEMS, THE HEAVIEST OF WHICH WAS BROUGHT BY TROPICAL STORM FAYE ON JULY 18 WHICH BOASTED THE NINTH HIGHEST JULY DAILY RAINFALL OF 177.7 MILLIMETRES.
THE RED AND BLACK RAINSTORM WARNINGS WERE ISSUED THAT THE FIRST TIME SINCE THE INCEPTION OF THE SYSTEM IN JUNE.
DAY FOR
ALTHOUGH THERE WERE DAYS WITH HEAVY RAIN, THE SUBTROPICAL RIDGE OF HIGH PRESSURE REMAINED A DOMINANT FEATURE IN THE MONTH.
FINE CONDITIONS WERE SOON RESTORED AFTER EACH STORMY AND THERE WAS A SPELL OF SUNNY WEATHER IN LATE JULY.
AS A RESULT, THE MONTHLY MEAN PRESSURE OF 1,007.9 TURNED OUT TO BE THE THIRD HIGHEST ON RECORD FOR JULY.
THE FIRST DAY IN THE MONTH WAS FINE AND WARM.

BUT OVER THE NEXT SIX DAYS, THE SOUTHWEST MONSOON INCREASED STRENGTH PROGRESSIVELY AND WINDS WERE RATHER GUSTY AT TIMES. SHOWERS, OCCURRING MAINLY IN THE MORNINGS, REMAINED LIGHT AND BRIEF.
THE WEATHER TURNED CLOUDIER ON JULY 4 AND WINDS BECAME OCCASIONALLY STRONG OFFSHORE THE NEXT DAY AS A TROUGH OF LOW PRESSURE FORMED OVER SOUTHERN CHINA.
AS THE TROUGH MOVED SOUTHWARDS ACROSS GUANGDONG, THE SOUTHWEST MONSOON BECAME MORE ACTIVE AND WINDS BECAME GENERALLY STRONG ON JULY 6.
THE WEATHER DETERIORATED WITH AN INTENSE OUTBREAK OF RAIN AND THUNDERSTORMS THAT EVENING. TEMPERATURES AT THE ROYAL OBSERVATORY DROPPED BY MORE THAN FOUR DEGREES IN AN HOUR AS THE RAIN SET IN.
THE LOWEST TEMPERATURE OF THE MONTH, 23.4 DEGREES, WAS RECORDED ON JULY 7. FRESH TO STRONG MONSOON WINDS PREVAILED UNTIL THE TROUGH CROSSED THE SOUTH CHINA COAST THAT DAY.
WINDS THEN TURNED NORTHERLY AND SUBSIDED
ON THE EVENING OF JULY 7.
HOWEVER, THE WEATHER STAYED CLOUDY WITH JULY 8 AS THE TROUGH LINGERED OVER THE GRADUALLY DISSIPATING.
