Hail-producing storms and supporting environments in the Philippines

Characterize the storm types that produce hail in the Philippines and identify the environmental conditions that support hail-producing storms across the archipelago.

Background

Historical hail research in the Philippines is limited, with early observations around the 1920s and more recent compilations of severe weather archives indicating spatial hotspots. Much of current process understanding derives from studies in the United States and Europe, which may not translate directly due to differences in CAPE, shear, and orographic influences.

Addressing this knowledge gap requires targeted regional analysis to delineate the environmental contexts and storm modes that lead to hail in the Philippine setting.
