Use of NWP for nowcasting convective precipitation: Recent progress and challenges
Traditionally, the nowcasting of precipitation was conducted to a large extent by means of extrapolation of observations, especially of radar ref lectivity. In recent years, the...- publication PDF

Uncertain pathways to a future safe climate
Global climate change is often thought of as a steady and approximately predictable physical response to increasing forcings, which then requires commensurate adaptation. But...- publication PDF

The substorm cycle as reproduced by global MHD models
Recently, Gordeev et al. (2015) suggested a method to test global MHD models against statistical empirical data. They showed that four community-available global MHD models...- publication PDF
