      In this paper, we describe the PALM model system 6.0. PALM (formerly an abbreviation for Parallelized Large-eddy Simulation Model and now an independent name) is a Fortran-based code and has been applied for studying a ...
    • The quiet crossing of ocean tipping points

      Anthropogenic climate change profoundly alters the ocean’s environmental conditions, which, in turn, impact marine ecosystems. Some of these changes are happening fast and may be difficult to reverse. The identification ...
    • Potential changes in the connectivity of marine protected areas driven by extreme ocean warming 

      Lima, Luciana S.; Gherardi, Douglas Francisco Marcolino; Pezzi, Luciano P.; Goncalves Dos Passos, Leilane; Kajiya Endo, Clarissa Akemi; Quimbayo, Juan Pablo (Journal article; Peer reviewed, 2021)
      Projected future climate scenarios anticipate a warmer tropical ocean and changes in surface currents that will likely influence the survival of marine organisms and the connectivity of marine protected areas (MPAs) networks. ...
    • Characteristics of cyclones following different pathways in the Gulf Stream region 

      Tsopouridis, Leonidas; Spensberger, Clemens; Spengler, Thomas (Journal article; Peer reviewed, 2021)
      The Northwest Atlantic is a region of strong temperature gradients and hence is a favourable location for wintertime cyclone intensification co-located with the storm track. The temperature gradient is associated with both ...
    • Impact of late spring Siberian snow on summer rainfall in South-Central China 

      Shen, Haibo; Li, Fei; He, Shengping; Orsolini, Yvan; Li, Jingyi (Journal article; Peer reviewed, 2020)
      Located in the Yangtze River Valley and surrounded by mountains, South-Central China (SCC) frequently suffered from natural disasters such as torrential precipitation, landslide and debris flow. Here we provide corroborative ...
