Among the hardest hit cities, 18 Macau experienced the worst flooding since 1925. In this paper, we present a high-resolution survey map recording 19 inundation depths and distances at 278 sites in Macau. We show that one half of the Macau Peninsula was inundated 20 with the extent largely confined by the hilly topography. The Inner Harbor area suffered the most with the maximum 21 inundation depth of 3.1m at the coast. -
The Cold War and Beyond
Contents Puge FOREWORD ...................... u 1947-56 ......................... 1 1957-66 ........................ 19 1967-76 ........................ 45 1977-86 ........................ 81 1987-97 ........................ 117 iii Foreword This chronology commemorates the golden anniversary of the establishment of the United States Air Force (USAF) as an independent service. Dedicated to the men and women of the USAF past, present, and future, it records significant events and achievements from 18 September 1947 through 9 April 1997. Since its establishment, the USAF has played a significant role in the events that have shaped modem history. Initially, the reassuring drone of USAF transports announced the aerial lifeline that broke the Berlin blockade, the Cold War’s first test of wills. In the tense decades that followed, the USAF deployed a strategic force of nuclear- capable intercontinental bombers and missiles that deterred open armed conflict between the United States and the Soviet Union. During the Cold War’s deadly flash points, USAF jets roared through the skies of Korea and Southeast Asia, wresting air superiority from their communist opponents and bringing air power to the support of friendly ground forces. In the great global competition for the hearts and minds of the Third World, hundreds of USAF humanitarian missions relieved victims of war, famine, and natural disaster. The Air Force performed similar disaster relief services on the home front. Over Grenada, Panama, and Libya, the USAF participated in key contingency actions that presaged post-Cold War operations. In the aftermath of the Cold War the USAF became deeply involved in constructing a new world order. As the Soviet Union disintegrated, USAF flights succored the populations of the newly independent states. -
Typhoon Signal Number 10
Typhoon Signal Number 10 The highest tropical cyclone warning signal in Hong Kong is Hurricane Signal Number 10, which means that hurricane force winds are expected or already blowing. Since 1946, the Number 10 Signal has been issued 16 times. The most recent T10 typhoon hitting Hong Kong was Typhoon Mangkhut, which struck Hong Kong in September 2018, felling tens of thousands of trees, causing severe flooding in many parts of Hong Kong, and bringing traffic to a standstill. There have been other typhoons in Hong Kong’s history, however, which have caused even more damage. For instance, Typhoon Wanda in 1962 created storm surges that caused rows of squatter shacks to collapse, claiming over 100 lives and resulting in heavy property damage. To provide more information about the persistent threat of typhoons to our city, the new permanent exhibition will have a corner titled “Typhoon Signal Number 10”, shedding light on the relationship between climate change and social development, and focusing on the following five major typhoons: 1. Wanda (1962) 2. Ruby (1964) 3. Rose (1971) 4. Hope (1979) 5. Ellen (1983) You may wonder why all these typhoons have taken female names! Starting in 1952, female names were used by the Hong Kong Observatory for typhoons; male names were added in 1979. Since 2000 typhoons have no longer been limited to female or male names and can be endowed with regional characteristics.

An Evaluation of Hong Kong Harbor as A Typhoon Haven by Donald Alan / Mautner Lieutenant, United States Navy B.A., San Jose State University, 1968 Submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN METEOROLOGY from the NAVAL POSTGRADUATE SCHOOL September 1973 LIBRARY NAVAL POSTGRADUATE MONTEREY, SCmnn C ,UF. 93940 ABSTRACT This study evaluates the harbor of Hong Kong as a typhoon haven. Characteristics of the harbor under tropical cyclone conditions, including topographical effects on the wind, storm surge and reliability of moorings and anchorages are discussed and highlighted by two case studies (Typhoon ROSE, August 1971 and Typhoon WANDA, September 1962). Problem areas to be considered if remaining in port and possible evasion procedures for ships sailing from the port are examined for tropical cyclones approaching from various directions. Tropical cyclone tracks for 87 years of data (1884-1970) for the western North Pacific Ocean are examined in order to determine the probability of threat to the port of Hong Kong. -

Tropical Cyclone Warnings of Signal No. 8 Or Above Issued by the Observatory During the Passage of Ruby in September 1964
Tropical cyclone warnings of Signal No. 8 or above issued by the Observatory during the passage of Ruby in September 1964 Local Storm Warning issued at 7:00 a.m. on 5 September 1964 by the Royal Observatory. Local Storm Warning Signal No.7* was hoisted at 7:00 a.m., which means that gale or storm force winds with mean speed 34 knots or more are expected from the northeast quarter. At 7 a.m., Typhoon Ruby was centred near 21.3 degrees north, 115.3 degrees east, that is about 90 miles southeast of Hong Kong and was moving west at 10 knots. There is no recent information concerning wind strength near the centre of the typhoon but winds of 45 knots have been reported by a ship 100 miles east of Hong Kong. If it continues on its present track it will pass about 50 miles south of Hong Kong early this afternoon. Winds over the Colony are increasing. Local Storm Warning issued at 8:30 a.m. on 5 September 1964 by the Royal Observatory. Local Storm Warning Signal No.7* is still hoisted, which means that gale or storm force winds with mean speed 34 knots or more are expected from the northeast quarter. At 8 a.m., Typhoon Ruby was centred near 21.4 degrees north, 115.2 degrees east, that is about 80 miles southeast of Hong Kong and was moving west or west-northwest at 10 knots. There is no recent information concerning wind strength near the centre of the typhoon but winds of 32 knots have been reported on the coast about 75 miles east of the Colony. -
Typhoons Affecting Hong Kong: Case Studies
Typhoons affecting Hong Kong: Case Studies by S. Campbell The Hong Kong University of Science and Technology A report submitted for the APEC 21st Century COE Short Term Fellowship April 2005 Abstract This report, “Typhoons affecting Hong Kong: Case Studies”, accompanies the main document concerning wind-induced damage in Hong Kong, entitled “History of Wind Damage in Hong Kong”. The case studies presented in this report offer the raw data collected from a selected number of storms that have severely damaged Hong Kong or highlighted its vulnerability to typhoons. For a summary of the overall effects of wind and wind-induced damage in Hong Kong, the reader is advised to examine “History of Wind Damage in Hong Kong”. The reader wanting more detail into specific damage occurring during typhoons is recommended to also read this report. This report contains data and qualitative reports from the Hong Kong Observatory, newspapers (published in English) and other sources. While information from the Hong Kong Observatory and newspapers can generally be trusted, other sources, although being valuable, may be anecdotal. Nevertheless, the gathered information is presented as raw data with few comments from the author, thus providing an unbiased account as to what happened during each typhoon. In addition to “The History of Wind Damage in Hong Kong” and this report, the following is also provided in electronic format for future use solely by the staff and students at Tokyo Polytechnic University: a) A tabulated summary of quantitative typhoon measures and damage categories in the file “COE_WindDamage_HK.xls”. This table contains all relevant typhoon-induced damage data collected between the years 1957 to 2004, inclusive.
