Trigo,Sven Ulbrich,Uwe Ulbrich,Xiaolan L. Wang,Heini Wernli +35 more
TL;DR: In this article, the variability of results from different automated methods of detection and tracking of extratropical cyclones is assessed in order to identify uncertainties related to the choice of method.

Objective climatology of cyclones in the Mediterranean region: a consensus view among methods with different system identification and tracking criteria
Piero Lionello,Isabel F. Trigo,Victoria Gil,Margarida L. R. Liberato,Katrin M. Nissen,Joaquim G. Pinto,Christoph C. Raible,Marco Reale,Annalisa Tanzarella,Ricardo M. Trigo,Sven Ulbrich,Uwe Ulbrich +11 more
TL;DR: In this article, the authors assess the level of consensus among cyclone detection and tracking methods (CDTMs), to identify robust features and to explore sources of disagreement, and show that cyclogenesis areas such as the northwestern Mediterranean, North Africa, north shore of the Levantine basin, as well as the seasonality of their maxima are robust features on which methods show a substantial agreement.
Journal ArticleDOI
Cyclones causing wind storms in the Mediterranean: characteristics, trends and links to large-scale patterns
TL;DR: In this paper, the authors presented a climatology of cyclones with a focus on their relation to wind storm tracks in the Mediterranean region (MR) based on the ERA40 reanalysis dataset.
Journal ArticleDOI
Are greenhouse gas signals of Northern Hemisphere winter extra-tropical cyclone activity dependent on the identification and tracking algorithm?

Wang,Heini Wernli +24 more
TL;DR: In this paper, the impact of the used algorithm on the changing signal, not the robustness of the climate change signal itself, was investigated for Northern Hemisphere extra-tropical cyclone activity, using one single transient AOGCM simulation as standard input for eleven state-of-theart identification methods.
