  • Decrease in the spatial inhomogeneity of tropical cyclone rainfall in China

    Open AccessDong Huang, Shengyuan Liu et al.ARTICLEEnvironmental Research Letters2025

    The increasing impact of tropical cyclone (TC) rainfall underscores the need to understand regional variations in its spatial distribution. Using high-resolution satellite precipitation data from 1998–2023, this study investigates changes in the spatial inhomogeneity of TC rainfall across China. Results show that TC rainfall inhomogeneity decreases significantly by about 65%, indicating a reduced rainfall in historically high-TC-rainfall areas an…

  • Detecting the impact of climate change on tropical cyclones in Southern China

    Open AccessShifei Tu, Yifan Zhang et al.ARTICLEEnvironmental Research Letters2024

    It is well known that tropical cyclones (TCs) making landfall in Southern China (SC) account for more than half of all TCs making landfall in China. Therefore, it is important to have an in-depth understanding of the activities of TCs in SC under climate warming. Our results show that there have been no significant changes in the frequency and duration of these TCs, but their intensities have unexpectedly decreased by ∼20% since 1980, which is in…

  • Effects of tropical cyclone intensity on spatial footprints of storm surges

    Open AccessChuangwu Deng, Shifei Tu et al.ARTICLEEnvironmental Research Letters2024

    Storm surges caused by tropical cyclones (TCs) have long ranked first among all types of marine disasters in casualties and economic losses, and can lead to further regional exacerbation of consequences stemming from these losses along different coastlines. Understanding the spatial footprints of storm surges is thus highly important for developing effective risk management and protection plans. To this end, we designed an ideal storm surge model…

  • Modulation of the cold tongue mode (CTM) in tropical cyclone genesis over the western North Pacific during 1975–2021

    Open AccessC H LIN, Chunqiao Lin et al.ARTICLEEnvironmental Research Letters2024

    The cold tongue mode (CTM) in the tropical Pacific enhanced with the global warming in the recent decades. Here, we show that the change of oceanic thermal condition and atmospheric circulation plays a critical role in the tropical cyclones (TCs) genesis in the western North Pacific (WNP). The frequency of TCs in the WNP decreases with its northwest movement, when the CTM transitions from its negative phase in 1975–1997(P1) to positive phase in 1…

  • Exploring spatiotemporal pattern in the association between short-term exposure to fine particulate matter and Covid-19 incidence in the continental United States

    Open AccessShiyi Liu, Shuming Ji et al.ARTICLEFrontiers in Public Health2023

    Background Numerous studies have demonstrated that fine particulate matter (PM 2.5 ) is adversely associated with COVID-19 incidence. However, few studies have explored the spatiotemporal heterogeneity in this association, which is critical for developing cost-effective pollution-related policies for a specific location and epidemic stage, as well as, understanding the temporal change of association between PM 2.5 and an emerging infectious disea…

  • Differences in the destructiveness of tropical cyclones over the western North Pacific between slow- and rapid-transforming El Niño years

    Open AccessShifei Tu, Jianjun Xu et al.ARTICLEEnvironmental Research Letters2020

    The relationship between the destructive potential of tropical cyclones (TCs) over the western North Pacific (WNP) (as quantified by the Power Dissipation Index) and El Niño events is investigated in this work. Results show that the destructive potential of TCs is significantly affected by how rapidly El Niño decays from a positive phase to a negative phase. For TCs occurring during ‘slow-transforming’ El Niño, more of them initiate over the sout…

  • Observed variability of intertropical convergence zone over 1998—2018

    Open AccessChunlei Liu, Xiaoqing Liao et al.ARTICLEEnvironmental Research Letters2020

    The intertropical convergence zone (ITCZ) accounts for more than 30% of the global precipitation and its variability has a great effect on the people living in the tropical area. It is the manifestation of the Hadley circulation, tropical dynamic and thermodynamic coupling and the air-sea interaction. Therefore, it is essential to understand the changes and variability of the ITCZ, including its position and intensity. Using observed precipitatio…

  • Regime shift in the destructiveness of tropical cyclones over the western North Pacific

    Open AccessShifei Tu, Feng Xu et al.ARTICLEEnvironmental Research Letters2018

    The characteristics of tropical cyclones (TCs) and their response to climate change is an issue of broad concern. Based on the Power Dissipation Index (PDI) proposed by Emanuel in 2005, the destructiveness of TCs in the typhoon season (July–October) during the period 1979–2016 over the western North Pacific is investigated. Results show that a regime shift in the destructive potential of TCs took place around 1998. The destructive potential of TC…
