Evaluating Sea Breezes and Associated Convective Cloud Evolution in the Model Gray Zone

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract We characterize convective clouds associated with sea‐breeze circulations (SBC) using multi‐agency observations and multi‐case ensemble model simulations. The focus is on assessing convective cloud lifecycle properties and their merging behavior, as well as the environmental conditions they are embedded in, particularly SBC features. In total,

Radar High Resolution Range & Micro-Doppler Analysis of Human Motions [PDF]

open access: yes, 2009
In radar imaging it is well known that relative motion or deformation of parts of illuminated objects induce additional features in the Doppler frequency spectra.

Radar principles [PDF]

open access: yes
Discussed here is a kind of radar called atmospheric radar, which has as its target clear air echoes from the earth's atmosphere produced by fluctuations of the atmospheric index of refraction.

Exposing Process‐Level Biases in a Global Cloud Permitting Model With ARM Observations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The emergence of global convective‐permitting models (GCPMs) represents a significant advancement in climate modeling, offering improved representation of deep convection and complex precipitation patterns. In this study, we evaluate the performance of the Simple Cloud‐Resolving E3SM Atmosphere Model (SCREAM) using its doubly periodic ...

Advancing Ionospheric Irregularity Reconstruction With ICON/MIGHTI Wind‐Driven Insights

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract In the mesosphere‐lower thermosphere region, atmospheric plasma components exhibit short‐term enhancements, forming sporadic E (Es) layers that impact communication systems. The prevailing theory posits that neutral wind shear is the primary driver of mid‐latitude Es layer.
