Geological History of the Western North Pacific

Science, 1970
A considerable portion of the abyssal floor of the western North Pacific was already receiving pelagic sediment in late Jurassic time. Carbonate sediments were later replaced by abyssal clays as the basin deepened and bottom waters became more aggressive.

Methane in the western North Pacific

Journal of Oceanography, 1995
The concentration of methane in about 400 seawater samples collected in the western North Pacific, mostly from 40°N to 5°S along 165°E was determined. While the concentration of methane in the surface water was slightly greater in the high-latitudes, it did not widely vary with a standard deviation of 0.29 n mol/l for a mean value of 2.49 n mol/l.

Possible relation of the western North Pacific monsoon to the tropical cyclone activity over western North Pacific

International Journal of Climatology, 2015
ABSTRACTThis study examined the relationship between the western North Pacific monsoon (WNPM) and the tropical cyclone (TC) activity over western North Pacific during the summer (June to August) in a period from 1977 to 2013. According to the western North Pacific monsoon index (WNPMI), 10 years with high indices (referred to as the positive WNPMI ...

Chlorofluorocarbons in the western North Pacific in 1993 and formation of North Pacific intermediate water

Journal of Oceanography, 1996
Chlorofluorocarbons (CFC-11 and CFC-12) in the intermediate water having σθ between 26.4 and 27.2 were determined at 75 stations in the western North Pacific north of 20°N and west of 175.5°E in 1993. The intermediate water of 26.4–26.6σθ was almost saturated with respect to the present atmospheric CFC-11 in the zone between 35 and 45°N around the ...

Influence of the Western Pacific teleconnection pattern on Western North Pacific tropical cyclone activity

Dynamics of Atmospheres and Oceans, 2012
Abstract This study analyzes the characteristics of Western North Pacific (WNP) tropical cyclone (TC) activity and large-scale environments according to the Western Pacific (WP) teleconnection pattern in summer. In the positive WP phase, an anomalous cyclone and an anomalous anticyclone develop in the low and middle latitudes of the East Asia area ...

Decadal Variability of the Anticyclone in the Western North Pacific

Journal of Climate, 2020
AbstractThe western North Pacific anomalous anticyclone (WNPAC) significantly affects East Asian climate. Previous studies have elucidated interannual variability of the WNPAC associated with El Niño, but decadal variability of the WNPAC remains unknown.

Influence of the North Pacific Victoria mode on western North Pacific tropical cyclone genesis

Climate Dynamics, 2018
The Victoria mode (VM) is defined as the second empirical orthogonal function mode (EOF2) of sea surface temperature anomalies (SSTAs) in the North Pacific north of 20°N. This study examines the influence of the spring VM on the tropical cyclone (TC) genesis over the western North Pacific (WNP) during summer (May–August) for the period 1960–2016.

Interannual variability of western North Pacific SST anomalies and its impact on North Pacific and North America

Climate Dynamics, 2017
In this study, the interannual variability of sea surface temperature (SST) and its atmospheric teleconnection over the western North Pacific (WNP) toward the North Pacific/North America during boreal winter are investigated. First, we defined the WNP mode as the first empirical orthogonal function (EOF) mode of SST anomalies over the WNP region (100 ...

Splitting of the subtropical gyre in the western North Pacific

Journal of Oceanography, 1978
Examined here is a hypothetical idea of the splitting of the subtropical gyre in the western North Pacific on the basis of two independent sources of data,i.e., the long-term mean geopotential-anomaly data compiled by the Japanese Oceanographic Data Center and the synoptic hydrographic (STD) data taken by the Hakuho Maru in the source region of the ...

Plutonium in sea waters of the western North Pacific

Journal of Radioanalytical and Nuclear Chemistry, 2001
Plutonium concentrations in seawater of the western North Pacific observed over the period from 1985 to 1997 are reported. In the 1990's, surface 239,240Pu concentrations in the western North Pacific were relatively homogeneous (around 3 mBq/m3), although surface 239,240Pu before the 1980's showed a latitudinal distribution with highs in mid-latitudes ...
