“…A detailed investigation of the mechanisms underpinning changes of non-TC rainfall is highly recommended to fully interpret previous trends of total rainfall over Vietnam. 195919641969197419791984198919941999200420142019Year Number SOLA, 2020, Vol. X, XXX-XXX, doi: 10.2151…”

“…Using data from 203 stations across Southeast Asia for the period 1950s−2000s, Endo et al (2009) demonstrated that there were more stations with significant trends of declining rainfall, compared to those with significant trends of increasing rainfall. Total annual rainfall and several extreme rainfall indices increased in southern Vietnam, but decreased in northern Vietnam during the period 1950s−2007 (Endo et al 2009), 1960−2011(Ngo-Duc 2014), and 1961(Trinh-Tuan et al 2019.…”

This study investigated rainfall trends and their associations with tropical cyclones (TCs) during the period of 1979−2019, using TC best-track data from the Regional Specialized Meteorological Center Tokyo -Typhoon Center and daily rainfall data from 138 meteorological stations in Vietnam. The radius of influence of TCs on local rainfall Pham-Thanh et al., Rainfall trends in Vietnam and their associations with Tropical Cyclones 2 was limited to 500 km from TC centers. The average annual number of TCs affecting Vietnam has decreased slightly in the last two decades compared to previous decades.The ratio of TC-induced rainfall to total rainfall attained the highest value of 37.3% in the central region, in July. The temporal distribution of TC-induced rainfall coincided with the frequency of TCs, with an active period from June to November. During 1979−2019, the non-TC rainfall was the main contributor to the change in total rainfall, especially in relation to the decline in the north and the increase in the coastal South Central region. The rainfall trend during the entire period was principally explained by the interdecadal shift in the late 1990s. Rainfall intensity and the number of heavy rainfall days were intensified for total rainfall and non-TC rainfall, indicating that TCs contributed minimally to the changes of extreme rainfall events during 1979−2019.

“…Our northern and southern sampling areas located at nearly the distal ends of the Vietnamese coastline, and it has been reported that the coast of Vietnam exhibits a remarkable environmental shift from north to south. The environmental gradients include average sea surface temperature (23–26–27°C or 25–28–30°C depending on studies); salinity (31–34–31 psu), and dissolved oxygen (4.5–4.0–3.8 ml L -1 ) [29, 30]. These physical factors are definitely important influences shaping the fish faunae.…”

DNA barcoding of coastal ray-finned fishes in Vietnam

et al. 2019

DNA barcoding based on a fragment of the cytochrome c oxidase subunit I (COI) gene is widely applied in species identification and biodiversity studies. The aim of this study was to establish a comprehensive barcoding database of coastal ray-finned fishes in Vietnam. A total of 3,638 specimens were collected from fish landing sites in northern, central and southern Vietnam. Seven hundred and sixty-five COI sequences of ray-finned fishes were generated, belonging to 458 species, 273 genera, 113 families and 43 orders. A total of 59 species were newly recorded in Vietnam and sequences of six species were new to the Genbank and BOLD online databases. Only 32 species cannot be annotated to species level because difficulty in morphological identifications and their Kimura-2-Parameter (K2P) genetic distances to most similar sequences were more than 2%. Moreover, intra-specific genetic distances in some species are also higher than 2%, implying the existence of putative cryptic species. The mean K2P genetic distances within species, genera, families, orders and classes were 0.34%, 12.14%, 17.39%, 21.42%, and 24.80, respectively. Species compositions are quite different with only 16 common species among northern, central and southern Vietnam. This may attribute to multiple habitats and environmental factors across the 3,260 km Vietnamese coastline. Our results confirmed that DNA barcoding is an efficient and reliable tool for coastal fish identification in Vietnam, and also established a reliable DNA barcode reference library for these fishes. DNA barcodes will contribute to future efforts to achieve better monitoring, conservation, and management of fisheries in Vietnam.

“…While there is no clear increasing or decreasing trend for the GCM rainfall, the RCM products exhibit a clear decreasing trend in the future. One should note that a drier tendency was detected in the northern part while an increasing rainfall trend was identified in some areas of the southern part of Vietnam in the past decades (Endo et al ., 2009; Ngo‐Duc, 2014). For future projections, the drier condition in the RegCM experiments over Vietnam under RCP8.5 was also reported previously (Tangang et al ., 2018; Trinh‐Tuan et al ., 2019).…”

This study uses six regional climate model (RCM) experiments from the Coordinated Regional Climate Downscaling Experiment—Southeast Asia (CORDEX‐SEA) and their driving global climate models (GCM) to investigate the model performance and the time of emergence (ToE) of temperature and precipitation over Vietnam and its seven sub‐climatic regions. A simple delta (multiplicative) bias correction (BC) method has been applied to the model temperature (precipitation). Results show clear added values of the BC downscaled products compared to their driving GCMs, particularly for temperature. The projected trends of RCM temperature during 2006–2100 under two representative concentration pathway (RCP) RCP4.5 and RCP8.5 scenarios are similar to those of their driving GCMs. Consequently, the RCM‐based ToE and GCM‐based ToE are generally consistent for temperature, occurring in the beginning of the 21st century. The earliest and latest ToE occur in summer and winter, respectively. The seasonal differentiation for temperature‐ToEs is stronger in the northern areas compared to the southern areas of Vietnam. The ToE difference between two RCPs increases from the south to the north. As for precipitation, ToE occurs quite late, in the latter half of the 21st century at the earliest. Results from ToE estimations also indicate an opposite precipitation trend between the GCMs and RCMs. The largest difference is in summer over the southern region of Vietnam. The opposite trend between the GCM and RCM precipitation under a similar increasing temperature implies the uncertainty in assessing the impact of warming on hydrological cycles in Vietnam.
