Sea Level Change in Hong Kong from Tide Gauge Records
نویسندگان
چکیده
The results from the study indicate that there is a rising trend of 1.9±0.4 mm per year in the sea level of Hong Kong. The effect of local atmospheric pressure variations on the amplitude of the annual sea level change is about 30% of the amplitude. It is also found that the interannual variations in the sea level of Hong Kong are related to El Nino and La Nina events that occur frequently in the tropical Pacific. It is projected from an extrapolation of the current trends of seal level rise and ground subsidence that the possible maximum relative mean sea level change will be as high as 50 cm in the next half century when considering the various temporal variations.

Evaluation of Coastal Sea Level Offshore Hong Kong from Jason-2 Altimetry
As altimeter satellites approach coastal areas, the number of valid sea surface height measurements decrease dramatically because of land contamination. In recent years, different methodologies have been developed to recover data within 10–20 km from the coast. These include computation of geophysical corrections adapted to the coastal zone and retracking of raw radar echoes. In this paper, we ...

West Palm Beach (Florida), ISSN 0749-0208. Without sea-level acceleration, the 20th-century sea-level trend of 1.7 mm/y would produce a rise of only approximately 0.15 m from 2010 to 2100; therefore, sea-level acceler...
متن کاملAre Long Tide Gauge Records in the Wrong Place to Measure Global Mean Sea Level Rise?
Ocean dynamics, land motion, and changes in Earth’s gravitational and rotational fields cause local sea level change to deviate from the rate of global mean sea level rise. Here we use observations and simulations of spatial structure in sea level change to estimate the likelihood that these processes cause sea level trends in the longest and highest-quality tide gauge records to be systematica...
متن کاملConsiderations for Estimating the 20th Century Trend in Global Mean Sea Level
Recent efforts in reconstructing historical sea level change have led to a range of published estimates for the global mean sea level trend over the last century. Disagreement in these estimates can be attributed to two factors: (1) differences in analysis and/or reconstruction techniques and (2) differences in tide gauge selection and quality control of the data. Here the impact of tide gauge ...

The mean sea level trend estimates from shorter records (less than 50 years) are easily influenced by a number of additional transient effects including atmospheric pressure variations, interannual and decadal changes in the mean sea level or various station dependent disturbances, which are not always accounted for in previous studies because their influences may be negligible for stations lon...
