Characteristics of easterly severe weather setups in the Philippines

Characterize the storm-severity-relevant properties of easterly severe weather setups in the Philippines, including their kinematic and thermodynamic features, to understand how these setups contribute to severe hazards such as large hail.

Background

The authors highlight a growing idea of ‘easterly severe weather setups,’ noting winds aloft shifting to (north)easterly components and largely unidirectional speed shear with meager near-surface winds. Unlike more familiar southwesterly monsoon setups, these cases may relate to monsoonal breaks and present different severe-convection characteristics.

The paper calls for systematic paper to define the environmental signatures and severity-related traits of these easterly setups, which could inform regional forecasting and hazard assessment.
