Seasonal Variation of GPS-Derived the Principal Ocean Tidal Constituents’ Loading Displacement Parameters Based on Moving Harmonic Analysis in Hong Kong
نویسندگان
چکیده
The classical harmonic analysis (CHA) method only can be used to obtain the constants (amplitude and phase) of ocean tide loading displacement (OTLD). In fact, there are significant seasonal variations in OTLD. A moving (MHA) is proposed, which effectively capture variation OTLD parameters. Based on 5 years kinematic coordinate time series direction U six Global Positioning System (GPS) stations Hong Kong, MHA explore parameters 6 principal tidal constituents (M2, S2, N2, K1, O1, Q1). influence mass analyzed. results show that obviously Kong. OTLD’s amplitude’s changes around 4–25.1% oscillation ranges phase vary from 8.8° 20.4°. Among parameters, annual signal, semi-annual ter-annual signal most significant. By analyzing atmospheric it found has certain contribution Hydrological non-tidal have little

15 صفحه اولSeasonal pattern of tuberculosis in Hong Kong.
BACKGROUND Summer predominance of tuberculosis (TB) was reported previously in temperate regions. No consistent data were available for lower latitudes. METHOD The monthly TB notification data in Hong Kong from 1991 to 2002 were examined for seasonal fluctuation. A seasonal model was then developed after standardization by period, sex, age, history of TB, form of disease, and bacteriological ...
متن کاملDetecting andmitigating ocean tidal loading displacements in the Bay of Fundy using GPS
Tidal induced displacement is one of the systematic errors that contribute to the scatter in the geodetic measurements derived from the GPS system. This paper focuses on ascertaining and reducing tidal induced errors due to ocean tide loading (OTL) at two GPS sites, namely CGSJ (Coast Guard Saint John, New Brunswick) and DRHS (Digby High School, Nova Scotia), established under the Princess of A...
متن کاملThe Contribution of Ageing to Hospitalisation Days in Hong Kong: A Decomposition Analysis
Background Ageing has become a serious challenge in Hong Kong and globally. It has serious implications for health expenditure, which accounts for nearly 20% of overall government expenditure. Here we assess the contribution of ageing and related factors to hospitalisation days in Hong Kong. We used hospital discharge data from all publicly funded hospitals in Hong Kong between 2001 and 2012. ...
