The Spatial Transformation Process and Critical Time Node Detection in Global Extreme High Temperature Clusters

open access: yesEarth and Space Science, Volume 8, Issue 2, February 2021., 2021
Abstract Extreme high temperature (EHT) events have caused serious impact on society. In previous research, EHT indices seldom consider spatial aggregation. To conduct the comprehensive evaluation, the global EHT days from 1979 to 2017 have been evaluated in terms of high temperature duration, accumulative temperature intensities and magnitude of ...

The representation of winter Northern Hemisphere atmospheric blocking in ECMWF seasonal prediction systems

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 147, Issue 735, Page 1344-1363, January 2021 Part B., 2021
This article investigates the advancements of atmospheric blocking representation in the seasonal prediction system by ECMWF, as shown by the figure. Blocking representation has improved considerably in the last 10 years and ‐ although significant biases still exist in System5 especially over the European sector ‐ in many regions biases have been ...
