  • Genetic characterization of the male-sterile Japanese cedar ‘Fukushima-funen 3’ reveals a naturally pyramided genotype and a novel MS2 allele, and leads to the development of marker-assisted selection…

    Open AccessKakeru Kobayashi, Masahiro Watanabe et al.ARTICLETrees Forests and People2026

    Pollen allergies are an increasingly serious public-health issue worldwide. Japanese cedar ( Cryptomeria japonica D. Don, Cupressaceae) is an important forestry species in Japan that releases large amounts of airborne pollen in spring, causing severe allergic reactions. Planting male-sterile individuals is expected to reduce pollen dispersal effectively. ‘Fukushima-funen 3’ is a male-sterile individual whose causal gene has remained unidentified.…

  • Siberian heat extremes caused by Eurasian atmospheric teleconnections and amplified by local land surface conditions

    Open AccessNakbin Choi, Myong‐In Lee et al.ARTICLEEnvironmental Research Letters2025

    This study aims to examine the mechanisms that drive extreme heat events in Siberia during boreal spring. The results from this study suggest that the upper-level atmospheric waves across Eurasia induced by the warm sea surface temperature (SST) in the eastern North Atlantic and large snow melting in southern Siberia are responsible for a large temperature increase in Siberia. These suggested mechanisms are examined by both observed data analysis…

  • Westward shift of tropical cyclogenesis over the southern Indian Ocean

    Open AccessXi Cao, Masahiro Watanabe et al.ARTICLEEnvironmental Research Letters2024

    Tropical cyclones (TCs), commonly called cyclones in the southern Indian Ocean (SIO), represent one of the most devastating disasters in the oceanfront regions of Africa. The present study explores the long-term tendency of annual mean TC genesis location in the SIO. A notable westward shift is detected in the SIO TC genesis longitude since 1979, which is linked to an increase in the TC genesis frequency in the southwestern SIO and a decrease in …

  • Association between Total and Individual PCB Congener Levels in Maternal Serum and Birth Weight of Newborns

    Open AccessAkifumi Eguchi, Kenichi Sakurai et al.ARTICLEInternational Journal of…2022

    Maternal exposure to polychlorinated biphenyls (PCBs) during pregnancy is associated with a low birth weight; however, the congener-specific effects of PCB congeners are not well defined. In this study, we used maternal serum samples from the Chiba Study of Mother and Child Health (C-MACH) cohort, collected at 32 weeks of gestational age, to analyze the effects of PCB congener exposure on birth weight by examining the relationship between newborn…

  • Underestimated marine stratocumulus cloud feedback associated with overly active deep convection in models

    Open AccessN Hirota, Tomoo Ogura et al.ARTICLEEnvironmental Research Letters2021

    Cloud feedback remains the largest source of uncertainty in equilibrium climate sensitivity (ECS). Many studies have attempted to narrow uncertainties in cloud feedback and ECS by proposing observable metrics with high skill at predicting future climate, referred to as emergent constraints. These constraints are often associated with clouds, convection, and circulation, and are interrelated. However, physical explanations for these connections re…

  • Limiting global warming to 1.5 °C will lower increases in inequalities of four hazard indicators of climate change

    Open AccessHideo Shiogama, Tomoko Hasegawa et al.ARTICLEEnvironmental Research Letters2019

    Clarifying characteristics of hazards and risks of climate change at 2 °C and 1.5 °C global warming is important for understanding the implications of the Paris Agreement. We perform and analyze large ensembles of 2 °C and 1.5 °C warming simulations. In the 2 °C runs, we find substantial increases in extreme hot days, heavy rainfalls, high streamflow and labor capacity reduction related to heat stress. For example, about half of the world’s popul…

  • Influence of the Gulf Stream on the Barents Sea ice retreat and Eurasian coldness during early winter

    Open AccessKazutoshi Sato, Jun Inoue et al.ARTICLEEnvironmental Research Letters2014

    Abnormal sea-ice retreat over the Barents Sea during early winter has been considered a leading driver of recent midlatitude severe winters over Eurasia. However, causal relationships between such retreat and the atmospheric circulation anomalies remains uncertain. Using a reanalysis dataset, we found that poleward shift of a sea surface temperature front over the Gulf Stream likely induces warm southerly advection and consequent sea-ice decline …

  • What caused the cool summer over northern Central Asia, East Asia and central North America during 2009

    Open AccessKyung‐Ja Ha, Jung‐Eun Chu et al.ARTICLEEnvironmental Research Letters2012

    Cool and wet weather conditions hit northern Central Asia, East Asia and central North America during the 2009 summer in concert with a strong jet stream and a prominent meandering upper-level circulation in the Northern Hemisphere mid-latitudes despite the fact that the year 2009 is the fifth warmest year globally in the modern record. It is found that the conspicuous atmospheric variability in the entire Northern Hemisphere mid-latitudes during…
