Assessing wildfire dynamics during a megafire in Portugal using the MesoNH/ForeFire coupled model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Weather conditions affect megafires by inducing different fire behaviors over several days or weeks. The coupled MesoNH/ForeFire code was used to represent the dynamics of fire generating pyro‐convective clouds. To advance the understanding of wildfire dynamics, high‐resolution coupled fire–atmosphere modeling was employed.

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

open access: yesQuarterly 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 ...

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

open access: yesQuarterly 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.

Spatial and temporal variability of wet spells and their role in wet and dry summers and winters in Australia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The change in the frequency of wet spells in tropical Australia in summer primarily contributes to the change in precipitation between wet and dry years. In the extratropics, both the frequency and intensity of wet spells are important, especially in winter.

Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

The effect of reservoir networks on drought propagation

open access: yes, 2017
Human interventions in response to drought can both alleviate and enhance drought. Developments of infrastructure for freshwater storage, groundwater abstraction and irrigation have proved to be effective in overcoming meteorological and agricultural drought in many locations worldwide.
