  2. Summer • AT NOON AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE WAS 25 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 95 PER CENT. DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S PARK WAS 1. THE INTENSITY OF UV RADIATION WAS LOW. • PLEASE BE REMINDED THAT: THE TROPICAL CYCLONE SIGNAL NO. 3 HAS BEEN ISSUED. • THE AIR TEMPERATURES AT OTHER PLACES WERE: KING'S PARK 24 DEGREES; WONG CHUK HANG 26 DEGREES; TA KWU LING 24 DEGREES; LAU FAU SHAN 23 DEGREES; TAI PO 24 DEGREES; SHA TIN 25 DEGREES; TUEN MUN 26 DEGREES; TSEUNG KWAN O 25 DEGREES; SAI KUNG 25 DEGREES; CHEUNG CHAU 25 DEGREES; CHEK LAP KOK 26 DEGREES; TSING YI 24 DEGREES; SHEK KONG 25 DEGREES.

  3. Summer • BETWEEN 10:45 AND 11:45 A.M., THE MAXIMUM RAINFALL RECORDED IN VARIOUS REGIONS WERE: NORTH • DISTRICT 22 MM; SHA TIN 21 MM; TAI PO 19 MM; YUEN LONG 19 MM; SAI KUNG 17 MM; TSUEN WAN 16 MM; KOWLOON EAST 14 MM; KWAI TSING 11 MM; KOWLOON WEST 9 MM; TUEN MUN 8 MM; CENTRAL & WESTERN DISTRICT 4 MM; WAN CHAI 3 MM; EASTERN DISTRICT 3 MM; LANTAU ISLAND 2 MM; SOUTHERN DISTRICT 1 MM.

  4. Summer • 75.6 MILLIMETRES OF RAINFALL WERE RECORDED AT THE HONG KONG OBSERVATORY BETWEEN MIDNIGHT LAST NIGHT AND MIDDAY TODAY. HERE IS THE INFORMATION ON TYPHOON DAMREY : LOCATION : 19.0 DEGREES NORTH, 112.7 DEGREES EAST; MAXIMUM SUSTAINED WIND NEAR ITS CENTRE : 140 KM/H.

  5. Summer • Records of Felt Earth Tremors in Hong Kong • Since 1874, a total of 6 tremors of Intensity V (5) or above have been felt in Hong Kong. The strongest of these occurred in 1918 arising from a Magnitude 7.3 earthquake at Shantou about 300 kilometres east-northeast of Hong Kong. The tremor caused only minor damages and cracks to buildings locally and its intensity was estimated to be VI to VII (6 to 7) on the Modified Mercalli Scale. • From 1979 to present, a total of 51 locally felt tremors were reported, averaging two a year. Most of these tremors were of Intensity III to IV (3 to 4). There were five with Intensity II (2) and only one with a stronger Intensity V to VI (5 to 6). • The epicentres that caused most locally felt tremors lie outside Hong Kong, at Heyuan and Yangjiang in Guangdong, Beibu Wan, Taiwan and the Philippines. • Since 1979, there were altogether six locally felt tremors with epicentres located in Hong Kong, at Maipo (once in 1983) and near the east coast of Lantau Island (twice in 1982 and three times in 1995 respectively). All these tremors were below Intensities V (5).

  6. Summer • Explanation of Solar Eclipse • Solar eclipse occurs when the Moon is in line between the Earth and the Sun (see Figure 1). The Moon cast a shadow on the Earth's surface and obscurs some parts on the Sun. The porportion of the Sun being blocked depends on the position of the observer on the Earth. When only the Moon's penumbral shadow strikes the Earth, a partial eclipse of the Sun is observed. However, if the Moon's dark umbral shadow sweeps across Earth's surface, a total eclipse of the Sun is seen
