Volcano‐seismic signals such as long‐period events and tremor are important indicators for volcanic activity and unrest. However, their wavefield is complex and characterization and location using traditional seismological ... -
Effective buoyancy and CAPE: Some implications for tropical cyclones
(Quarterly Journal of the Royal Meteorological Society, 2022-06-01)We review the widely used concepts of “buoyancy” and “convective available potential energy” (CAPE) in relation to deep convection in tropical cyclones and discuss their limitations. A fact easily forgotten in applying ... -
Contrasting State‐Dependent Effects of Natural Forcing on Global and Local Climate Variability
; ; ; ; ; (Geophysical Research Letters, 2022-05-17)
Natural forcing from solar and volcanic activity contributes significantly to climate variability. The post‐eruption cooling of strong volcanic eruptions was hypothesized to have led to millennial‐scale variability during ... -
The relationship between precipitation and its spatial pattern in the trades observed during EUREC4A
;; ; (Quarterly Journal of the Royal Meteorological Society, 2022-05-16)
Trade wind convection organises into a rich spectrum of spatial patterns, often in conjunction with precipitation development. Which role spatial organisation plays for precipitation and vice versa is not well understood. ... -
