Mapping the global threat of Mythimna separata (Walker) and its economic implications for Brazil's agriculture

open access: yesPest Management Science, EarlyView.
Global models identified high‐risk areas for Mythimna separata invasion, highlighting major economic vulnerability for Brazilian crops and guiding targeted prevention and management strategies. Abstract BACKGROUND Identifying high‐risk areas for the introduction of invasive alien species is particularly important for agricultural pests with a broad ...

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

An opportunity index to anticipate when subseasonal predictions are useful

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Simultaneously active subseasonal windows of forecast opportunity can be combined into a single opportunity index, which can be used operationally to anticipate enhanced or reduced subseasonal prediction skill. For predictions of temperature anomalies in Switzerland during summer—a region and season with particularly low predictability—skill can nearly

The airport Network and Catchment area Competition Model - A comprehensive airport demand forecasting system using a partially observed database [PDF]

open access: yes
For airport capacity planning long term forecasts of aircraft movements are required. The classical approach to generate such forecasts has been the use of time series data together with econometric models, to extrapolate observed patterns of growth into

Modulation of wind drag by tidal currents in an embayment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

A safe reinforcement learning approach for autonomous navigation of mobile robots in dynamic environments

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract When deploying mobile robots in real‐world scenarios, such as airports, train stations, hospitals, and schools, collisions with pedestrians are intolerable and catastrophic. Motion safety becomes one of the most fundamental requirements for mobile robots.
