Animal Biodiversity and Conservation, 42.2: 227–244, Doi: https://doi.org/10.32800/abc.2019.42.0227 Abstract Monitoring black grouse Tetrao tetrix in Isère, northern French Alps: cofactors, population trends and potential biases. Wildlife management benefits from studies that verify or improve the reliability of monitoring protocols. In this study in Isère, France, we tested for potential links between the abundance of black grouse (Tetrao tetrix) in lek–count surveys and cofactors (procedural, geographical and meteorological cofactors) between 1989 and 2016. We also examined the effect of omitting or considering the important cofactors on the long–term population trend that can be inferred from lek–count data. Model selections for data at hand highlighted that the abundance of black grouse was mainly linked to procedural cofactors, such as the number of observers, the time of first observation of a displaying male, the day, and the year of the count. Some additional factors relating to the surface of the census sector, temperature, northing, altitude and wind conditions also appeared depending on the spatial or temporal scale of the analysis. The inclusion of the important cofactors in models modulated the estimates of population trends. The results of the larger dataset highlighted a mean increase of +17 % (+5.3 %; +29 %) of the abundance of black grouse from 1997 to 2001, and a mean increase in population of +47 % (+16 %; +87 %) throughout the study period (1989–2016). -

Dynamic aspects of windstorm Kyrill (January 2007) Patrick Ludwig (1), Joaquim G. Pinto (1,2), Simona A. Hoepp (1), Andreas H. Fink (3), and Suzanne L. Gray (2) (1) Institute for Geophysics and Meteorology, University of Cologne, Cologne, Germany ([email protected]), (2) Department of Meteorology, University of Reading, Reading, United Kingdom, (3) Institute for Meteorology and Climate Research, Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany Several dynamical and mesoscale aspects concerning severe windstorm Kyrill (January 2007) are analysed by results of high-resolution simulations with the regional climate model (RCM) COSMO-CLM. After explosive cyclogenesis south of Greenland takes place while crossing a very intense upper-level jet stream, Kyrill underwent secondary cyclogenesis over the North Atlantic Ocean just west of the British Isles. The secondary cyclogenesis (Kyrill II), was located on the occlusion front of the mature cyclone (Kyrill I), which is very unusual compared to typical frontal cyclogenesis generally occurring along the trailing cold fronts of existing cyclones. The mechanisms of secondary cyclogenesis are investigated based on moderate-resolution (0.0625◦ grid spacing) RCM simulations. The formation of Kyrill II along the occlusion front follows common mechanism for secondary cyclogenesis like breaking up of a local, low tropospheric PV strip along the front and diabatic heating with associated development of a vertical extended PV tower. Kyrill II propagated further towards Europe, and its development was favoured by a split jet structure aloft the surface cyclone, which maintained the deep core pressure (around 961 - 965 hPa) for at least 36 hours. -

NOVEMBER 2017 B Ü ELER AND PFAHL 3567 Potential Vorticity Diagnostics to Quantify Effects of Latent Heating in Extratropical Cyclones. Part I: Methodology DOMINIK BÜELER AND STEPHAN PFAHL Institute for Atmospheric and Climate Science, ETH Zurich,€ Zurich, Switzerland (Manuscript received 9 February 2017, in final form 31 July 2017) ABSTRACT Extratropical cyclones develop because of baroclinic instability, but their intensification is often sub- stantially amplified by diabatic processes, most importantly, latent heating (LH) through cloud formation. Although this amplification is well understood for individual cyclones, there is still need for a systematic and quantitative investigation of how LH affects cyclone intensification in different, particularly warmer and moister, climates. For this purpose, the authors introduce a simple diagnostic to quantify the contribution of LH to cyclone intensification within the potential vorticity (PV) framework. The two leading terms in the PV tendency equation, diabatic PV modification and vertical advection, are used to derive a diagnostic equation to explicitly calculate the fraction of a cyclone’s positive lower-tropospheric PV anomaly caused by LH. The strength of this anomaly is strongly coupled to cyclone intensity and the associated impacts in terms of surface weather. To evaluate the performance of the diagnostic, sensitivity simulations of 12 Northern Hemisphere cyclones with artificially modified LH are carried out with a numerical weather prediction model. Based on these simulations, it is demonstrated that the PV diagnostic captures the mean sensitivity of the cyclones’ PV structure to LH as well as parts of the strong case-to-case variability. The simple and versatile PV diagnostic will be the basis for future climatological studies of LH effects on cyclone intensification. -
Severe Storm Xynthia Over Southwestern and Western Europe
Severe Storm Xynthia over southwestern and western Europe A severe storm named “Xynthia” affected Portugal, Spain, Switzerland, France, parts of south-east England, Belgium, the Netherlands, Luxembourg, Germany and Austria. Strong gusts on 27-28 February 2010 caused extended damage on traffic routes, electrical power outage, destruction due to flooding at the French Atlantic coast and more than 60 losses of lives. Most of the damage was in France and western Germany. The track of this storm and its rapid development were outstanding, but the magnitude of the gusts was comparable to other violent storms in the past. Synoptical development and weather conditions Xynthia arose from an initially shallow low pressure system which formed over the subtropical sea area south of the Azores Islands on Friday, 26 February 2010. The southward flow of colder air masses in the upper air caused the deepening of a broad trough over the central and eastern North Atlantic. A shortwave trough within this broader system and a high temperature difference between extremely warm air over Africa and colder air over the eastern Atlantic caused a strong cyclogenesis of Xynthia. On Saturday, February 27, the cyclone moved northeastwards over Portugal and the Bay of Biscay to the westernmost areas of France and intensified very rapidly to a core pressure of about 967 hPa around midnight which means a deepening of about 20 hPa within 24 hours (Fig. 1-3). During the following three days it began weakening and moved further northeastwards along the coastline of northern France and the North Sea, and then it crossed the southern Baltic Sea to southern Finland until March 3. -

The inquiry was adjourned in late September to enable further work to be carried out on highways modelling, and since then two further storm events have occurred which have greatly affected the UK in general and Warrington in particular. -
Orkantief Sabine Löst Am 09./10. Februar 2020 Eine Schwere Sturmlage Über Europa Aus
Abteilung Klimaüberwachung Orkantief Sabine löst am 09./10. Februar 2020 eine schwere Sturmlage über Europa aus Autor(inn)en: Susanne Haeseler, Peter Bissolli, Jan Dassler, Volker Zins, Andrea Kreis Stand: 13.02.2020 Zusammenfassung Orkantief SABINE (in Westeuropa CIARA und in Norwegen ELSA benannt) löste am 9./10. Februar 2020 deutschlandweit Sturmböen bis Orkanstärke (12 Bft) aus. Die höchste Böe meldete der Feldberg im Schwarzwald am 10. Januar mit 49,1 m/s bzw. 177 km/h. Der Kern des Orkantiefs zog vom Atlantik kommend über Schottland nach Norwegen, wobei der Kerndruck zeitweise unter 945 hPa lag. Zwischen Nord- und Südeuropa bestanden Luftdruckunterschiede von etwa 80 hPa. Das dadurch generierte Sturmfeld erfasste weite Teile West-, Mittel- und Nordeuropas. In Deutschland war der Sturm, der sich von der Nordsee in Richtung Alpen ausweitete, von teils kräftigen Schauern und Gewittern begleitet. An der Nordsee gab es vom 10. bis 12. Januar mehrere teils schwere Sturmfluten (Abb. 1 und 4). Die extreme Sturmlage war schon Tage vorher angekündigt und es wurde von Tätigkeiten im Freien sowie Reisen während dieser Zeit abgeraten. Sport- und Musikveranstaltungen wurden vorsichtshalber abgesagt. Am 9./10. Februar stellte die Bahn in Deutschland den Verkehr zeitweise ein. Flüge und Fährverbindungen fielen aus. Viele Schulen und Kindergärten blieben am 10. Februar geschlossen. Der Sturm ließ in den betroffenen Ländern Bäume umstürzen und deckte Hausdächer ab. Auf den Britischen Inseln kam es zu Überschwemmungen. In einigen Regionen (auch in Deutschland) gab es Stromausfälle. Abbildung 1: Sturmflut am Weststrand von Norderney.
