Meteorological conditions leading to a catastrophic, rain‐induced landslide in Cameroon in October 2019

Quarterly Journal of the Royal Meteorological Society, EarlyView.
October 2019 was characterized by three main multiday wet spells in Bafoussam and Dschang. Our results indicated that wet spells were influenced by a vortex pair near the Gulf of Guinea, a strong Sahara Heat Low located anomalously far east and north, a northward shift of the intertropical discontinuity, an enhancement of the inland penetration of the ...

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

Using the Debiased Brier Skill Score to Evaluate S2S Tropical Cyclone Forecasting

Journal of Marine Science and Engineering
To evaluate tropical cyclone forecasting on synoptic timescale, tracking and intensity are used. On subseasonal to seasonal (S2S) timescale, what aspects of tropical cyclones should be predicted and how to evaluate forecasting skills still remain open ...

Machine‐learning approaches for characterizing the raindrop size distributions in Western Pacific tropical cyclones

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Long‐term disdrometer observations are utilized to derive Z–R relationships for ‐the Western Pacific tropical cyclones. A hybrid moment‐based approach is employed to determine the interrelationships among pairs of gamma distribution parameters. Enhanced estimates of rainfall rate and slope parameter are obtained using machine‐learning techniques ...

Decreasing trend in destructive potential of tropical cyclones in the South Indian Ocean since the mid-1990s

Communications Earth & Environment
Tropical cyclone activity often leads to many adverse impacts and assessing their destructiveness is a crucial scientific concern. Here we investigated changes in the destructiveness of tropical cyclones worldwide using the power dissipation index and ...

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

The role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We use the Advanced Weather Research and Forecasting model to examine the role of soil moisture in the inland penetration of Indian monsoon low‐pressure systems (LPSs). We find that LPSs penetrate deeply into India despite a dry land surface; however, their inland penetration is adversely affected when there is a reduction in the total surface heat ...
