“…The Sargasso Sea is the part of the North Atlantic Ocean (known as the North Atlantic gyre) that is bounded by the surrounding clockwise-rotating system of major currents, i.e. the North Atlantic Current in the north, the Gulf Stream in the west, the North Atlantic Equatorial Current in the south, and the Canary Current in the east (Deacon, 1942;Laffoley et al, 2011). Hence, the Sargasso Sea essentially lies between the parallels 20-35 • N and the meridians 30-70 • W (Augustyn et al, 2013).…”

“…The ocean is the main source of energy for TC intensification; hence, changes in oceanic environments considerably affect TC activity (Knutson et al, 2010;Huang et al, 2015;Sun et al, 2017;Trepanier, 2020). Sea surface temperature (SST) and ocean heat content (OHC) have risen significantly over the past several decades in regions of TC formation (Santer et al, 2006;Defforge and Merlis, 2017;Trenberth et al, 2018;Cheng et al, 2019;Zanna et al, 2019;Chih and Published by Copernicus Publications on behalf of the European Geosciences Union. 838 D.

Abstract. Understanding the oceanic response to tropical cyclones (TCs) is of importance for studies on climate change. Although the oceanic effects induced by individual TCs have been extensively investigated, studies on the oceanic response to the passage of consecutive TCs are rare. In this work, we assess the upper-oceanic response to the passage of Hurricanes Dorian and Humberto over the western Sargasso Sea in 2019 using satellite remote sensing and modelled data. We found that the combined effects of these slow-moving TCs led to an increased oceanic response during the third and fourth post-storm weeks of Dorian (accounting for both Dorian and Humberto effects) because of the induced mixing and upwelling at this time. Overall, anomalies of sea surface temperature, ocean heat content, and mean temperature from the sea surface to a depth of 100 m were 50 %, 63 %, and 57 % smaller (more negative) in the third–fourth post-storm weeks than in the first–second post-storm weeks of Dorian (accounting only for Dorian effects), respectively. For the biological response, we found that surface chlorophyll a (chl a) concentration anomalies, the mean chl a concentration in the euphotic zone, and the chl a concentration in the deep chlorophyll maximum were 16 %, 4 %, and 16 % higher in the third–fourth post-storm weeks than in the first–second post-storm weeks, respectively. The sea surface cooling and increased biological response induced by these TCs were significantly higher (Mann–Whitney test, p<0.05) compared to climatological records. Our climatological analysis reveals that the strongest TC-induced oceanographic variability in the western Sargasso Sea can be associated with the occurrence of consecutive TCs and long-lasting TC forcing.

“…Hurricanes and typhoons (or more generally, tropical cyclones (TCs)) are among the most destructive natural phenomena on Earth leading to great social and economic losses (Welker and Faust, 2013;Lenzen et al, 2019), as well as ecological perturbations of both marine and terrestrial ecosystems (Fiedler et al, 2013;de Beurs et al, 2019;Lin et al, 2020). Given the devastating effects of TCs, the question of how they will be affected by climate change has received considerable scientific attention (Henderson-Sellers et al, 1998;Knutson et al, 2010;Walsh et al, 2016).…”

“…: 2147-4249 only increase (Long et al, 2018;Santoro and D'Amato, 2019). They affect not only coastal areas and islands, but also inland areas (Chernokulsky and Shikhov, 2018;Sahoo et al, 2019;De Beurs et al, 2019;Ezer, 2020). Currently, hurricanes, for example, have been appearing in new places where they've never met before (Hoffmann et al, 2018;Barrett et al, 2020).…”

Article InfoThe article presents the results of complex research (research was conducted in 2019) of the Botanical natural monument territory "Pine forest near Venetsiya village" (Russia). In 2007, part of the nature monument territory was destroyed by a hurricane, resulting in massive windfall. The purpose of the research was to study the processes of evolution of natural complexes (vegetation and soil cover) in the areas affected by the hurricane. Classification of vegetation was done according to the Braun-Blanquet and Kopečký and Hejný approaches. NDVI (Normalized Difference Vegetation Index) was used to estimate the amount of photosynthetically active biomass. Changes in morphological, physical and chemical properties were studied in the soil cover. The conducted research showed that the vegetation of the natural monument is represented by relict pine and broad-leaved pine forests. Under the pine canopy linden and birch are dominated. In the herb layer grow in various combinations of nemoral and boreal species. Soil cover is represented by Gray-humus (Umbric Luvisol). There is a strong transformation of vegetation in the areas damaged by the hurricane in 12 years (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019). There is an active formation of highly productive herbaceous vegetation and renewal of deciduous stands, which leads to an increase in biomass (confirmed by changes in NDVI). The terminal stage of the restoration succession will be the formation of secondary deciduous and mixed nemoral forests. The active development of grass vegetation leads to the formation of a sod horizon on the surface of the soil with a thickness of about 14 cm. There is also an increase in the content of organic carbon, alkaline-hydrolyzable nitrogen and mobile phosphorus, the value of electrical resistivity increases and acidification of the soil solution.
