Fukushima-derived radiocesium in the western North Pacific in 2014 [PDF]

Journal of Radioanalytical and Nuclear Chemistry, 2016
In 2014, we measured activity concentration of radiocesium in the western North Pacific Ocean. In the north of Kuroshio Front high activity concentration of Fukushima-derived radiocesium in surface mixed layer in 2012 had been transported eastward by 2014. In the south of the front we found a radiocesium subsurface maximum in 200-600 m depth, which was

Interannual Anomaly in Tropical Cyclone Frequency Around Korea by Western North Pacific Monsoon

Tropical Cyclone Research and Review, 2015
: In this study, the correlation between the frequency of summer tropical cyclones (TC) affecting areas around Korea over the last 37 years and the western North Pacific monsoon index (WNPMI) was analyzed. A clear positive correlation existed between the

Geolocator tagging links distributions in the non-breeding season to population genetic structure in a sentinel North Pacific seabird.

PLoS ONE, 2020
We tested the hypothesis that segregation in wintering areas is associated with population differentiation in a sentinel North Pacific seabird, the rhinoceros auklet (Cerorhinca monocerata).

Annular Typhoons in the Western North Pacific

Weather and Forecasting, 2014
Abstract Annular hurricanes, characterized by annular structure, are a subset of mature-stage intense tropical cyclones, and they tend to be stronger and persist longer than average tropical cyclones. The characteristics of annular hurricanes in the North Atlantic and eastern-central North Pacific Oceans are well documented by Knaff et ...

Evaluating the Emanuel-Nolan genesis potential index: Contrast between North Atlantic and western North Pacific

Terrestrial, Atmospheric and Oceanic Sciences, 2018
Tropical cyclone (TC) activity during the period from 1979 - 2010 represented by the Emanuel-Nolan “genesis potential index” (EN-GPI) is compared and evaluated against observation of TC records over the North Atlantic and the western North Pacific.

Trends in western North Pacific tropical cyclone intensity [PDF]

Eos, Transactions American Geophysical Union, 2006
Using the tropical cyclone best track data from the U.S. Department of Defense's Joint Typhoon Warning Center (JTWC), Webster et al. [2005] found that between the two consecutive 15‐year periods of 1975–1989 and 1990‐2004, the percentage of typhoons in the western North Pacific meeting the definition of categories 4 and 5 on the Saffir‐Simpson ...

Interdecadal variability of tropical cyclone genesis frequency in western North Pacific and South Pacific ocean basins

Environmental Research Letters, 2020
Variability of tropical cyclone (TC) genesis frequency in the western North Pacific and South Pacific ocean basins in the interdecadal scale is studied. It is demonstrated that the TC genesis frequency in these ocean basins experienced an abrupt decrease

Spatiotemporal vertical velocity variation in the western tropical Pacific and its relation to decadal ocean variability

Progress in Earth and Planetary Science, 2022
Prior to the cold phase of the Pacific decadal oscillation (PDO), sea surface water in the western tropical North Pacific is heated. To evaluate the impact of the subsurface water on the upper-ocean ( $$10^{-6}\,{\text {m\,s}}^{-1}$$ > 10 - 6 m\,s - 1 ...

Characteristics of the Nonoccurrence of Tropical Cyclones in the Western North Pacific in August 2014

Atmosphere, 2016
This study identified the causes of the nonoccurrence of tropical cyclones (TCs) in August 2014 by examining large-scale environments. First, over the previous 30 years, the TC genesis frequency in August showed an overall statistically significant ...
