    Association of climate variability modes with concurrent droughts and heatwaves in India by Ruhhee Tabbussum, Rajarshi Das Bhowmik, Pradeep Mujumdar

    Published 2025-01-01
    “…This study explores this association by demonstrating how concurrent droughts and heatwaves (CDHW) in India are temporally and spatially connected to multiple global teleconnections (referred to as climate variability modes). Composite and wavelet coherence analyses are implemented for the univariate evaluation of droughts and heatwaves—measured using the standardized precipitation index (SPI) and the standardized heat index (SHI), respectively—in relation to the climate variability modes. …”

    Modulation of the lunar semidiurnal tide in GNSS TEC by the variable Earth-Moon distance by Klemens Hocke, Klemens Hocke

    Published 2025-05-01
    “…Time series analysis shows that the M2 amplitude in GNSS TEC is modulated by the period of the anomalistic month (27.55455 days) which is the time interval from one perigee transit of the Moon to the next. The variable Earth-Moon distance or the eccentricity of the Moon orbit is clearly responsible for this modulation. …”

    Characterization of the mean and extreme Mediterranean cyclones and their variability during the period 1500 BCE to 1850 CE by O. Doensen, O. Doensen, M. Messmer, M. Messmer, M. Messmer, W. M. Kim, W. M. Kim, C. C. Raible, C. C. Raible

    Published 2025-07-01
    “…For the cyclone frequency, a weak statistical relationship is identified with the East Atlantic (EA), East Atlantic/Western Russia (EAWR), and Scandinavian (SCAN) modes of circulation. Composite analyses of the most extreme cyclones with respect to wind speed and precipitation indicate that cyclones in the central Mediterranean have the potential to grow more intense over their entire lifetime than cyclones in the eastern Mediterranean. …”
