Tropical Cyclone Diurnal Cycle as Observed by TRMM

open access: yesMonthly Weather Review, 2016
Abstract Previous work has indicated a clear, consistent diurnal cycle in rainfall and cold cloudiness coverage around tropical cyclones. This cycle may have important implications for structure and intensity changes of these storms and the forecasting of such changes.

Dynamics of Significant Intraseasonal Variability of Surface Chlorophyll‐a Concentration in the Far Western Tropical Pacific

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract While the far Western Tropical Pacific is known for interannual variability, we find intraseasonal variability (ISV) actually dominates surface chlorophyll (SChl) fluctuations, explaining >30% of variance. The Madden‐Julian Oscillation (MJO) acts as the key driver through three mechanisms: (a) positive MJO phase vertical mixing (enhanced winds

Severe convection features in the Amazon Basin: a TRMM-based 15-year evaluation

open access: yesFrontiers in Earth Science, 2016
Rainfall in the Amazon Basin is very heterogeneous, mainly because the area encompassed is quite large. Among the systems responsible for rainfall, some stand out as extreme storm events. This study presents a criterion for identifying potentially severe

Climate Change Amplifies Rainfall Sensitivity to Deforestation in the Southern Amazon

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Rainfall among the Amazon has been shown to decline sharply once forest loss exceeds a critical threshold, typically around 30%–40%. However, future interactions between climate change and deforestation on this threshold remain unclear. We model their combined effects by 2050 on rainfall and temperature.

Lightning Outbreaks at the Mature Stage of Tropical Cyclone: Case Study for Hurricane Dorian (2019)

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The relationship between tropical cyclone (TC) lightning activity and intensity change has been examined for nearly 30 years, yet a clear consensus remains elusive, reflecting the complexity of the processes governing TC lightning. This study investigates the physical mechanisms that triggered inner‐core lightning outbreaks during the mature ...

Pseudo‐Radar Reflectivity by Applying U‐Net Models to Global Passive Microwave Brightness Temperatures

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Spaceborne radar systems such as the Global Precipitation Measurement Mission (GPM)'s core satellite Dual‐frequency Precipitation Radar (DPR) provide global insight into precipitation structure, storm morphology, and hydrological cycles. However, their limited spatial and temporal sampling and high cost constrain their ability to continuously ...

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

open access: yesInternational Journal of Climatology, Volume 46, Issue 6, May 2026.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Inter-Comparison of Gauge-Based Gridded Data, Reanalysis and Satellite Precipitation Product with an Emphasis on Hydrological Modeling

open access: yesAtmosphere, 2020
Precipitation is essential for modeling the hydrologic behavior of watersheds. There exist multiple precipitation products of different sources and precision. We evaluate the influence of different precipitation product on model parameters and streamflow

Spatial Analysis of Tropical Cyclone Precipitation Through Landfall: A Multi‐Basin Perspective

open access: yesMeteorological Applications, Volume 33, Issue 3, May/June 2026.
We use a shape metric methodology to analyze the spatial evolution of tropical cyclone (TC) precipitation across the North Indian, Western Pacific, and North Atlantic basins. Across all basins, precipitation area decreases from pre‐landfall to post‐landfall, with closure decreasing and dispersion increasing, indicating an exposed TC center and outward ...

Decoupling Between Heavy Precipitation Expansion and Population Exposure in a Warming World

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract Climate change is intensifying the global water cycle, amplifying heavy precipitation and associated flood risks. However, the spatial extent of heavy precipitation—a critical factor for assessing total societal impact—has been largely overlooked. Here, we develop a method to identify the spatial extent of heavy precipitation that incorporates
