Spatio‐Temporal Representation of Mesoscale Convective Systems in Convection‐Permitting Simulations Over Northwestern South America: Insights Into Rainfall Overestimation

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 7, 16 April 2025.
Abstract We perform km‐scale convection‐permitting simulations (Δx = 4 km) to represent Mesoscale Convective Systems (MCSs) in Northwestern South America using the Weather Research and Forecasting (WRF) model. An algorithm to identify and track MCSs was used to characterize simulated MCS features and compare with satellite observations.

Deltas: New paradigms

The Depositional Record, Volume 10, Issue 5, Page 600-636, November 2024.
This paper discusses some new paradigms concerning the origin and significance of deltas and their deposits. It proposes a broader definition of deltas that takes into account the importance of sediment‐laden fluvial discharges in controlling deltaic sedimentation.

Climatological Tracking and Lifecycle Characteristics of Mesoscale Convective Systems in Northwestern South America

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 19, 16 October 2024.
Abstract Mesoscale convective systems (MCSs) are crucial in shaping large‐scale tropical circulation and the hydrological cycle, particularly in Northwestern South America (NwSA), a region marked by complex terrain and significant MCS activity. Understanding MCSs in NwSA is vital due to their impact on precipitation patterns and potential for severe ...

Radio Frequency Sensor: Very High Frequency Radio Frequency Lightning Detection in Geostationary Orbit

Radio Science, Volume 59, Issue 6, June 2024.
Abstract The Radio Frequency Sensor (RFS), a new radio frequency lightning detector, was launched into geosynchronous orbit in December 2021, and first collected data in January 2022. RFS is a specialized software‐defined radio receiver that detects, records, and reports impulsive broadband radio‐frequency (RF) signatures from lightning in the very ...

Recurrent Lightning Spots: Where Lightning Strikes More Than Twice

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 5, 16 March 2024.
Abstract The expression “lightning never strikes twice” is questioned in this paper because, among the randomness of lightning impacts, some spots are hit even more than twice year after year. This article introduces the recurrent lightning spots (RLS) concept, which are locations periodically impacted by cloud‐to‐ground lightning every consecutive ...

Lightning Characteristics Associated With Storm Modes Observed During RELAMPAGO

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 4, 28 February 2024.
Abstract Global satellite studies show a maximum in deep convection and lightning downstream of the Andes in subtropical South America. The Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations (RELAMPAGO) field campaign was designed to investigate the physical processes that contribute to ...
