A Deep Learning Model of Lightning Stroke Density

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Lightning plays a crucial role in the Earth's climate system; however, existing parameterizations for use in forecasting and earth system models show room for improvement in capturing spatial and temporal variations in its frequency. This study develops deep learning‐based parameterizations of lightning stroke density using meteorological ...

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

Frontiers 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

Structure, Propagation and Variability of the 5‐Day Rossby‐Haurwitz Wave

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract The 5‐day wave is the gravest free Rossby mode predicted by the Laplace shallow water equations, with a latitudinally symmetric, zonal wavenumber one theoretical structure in geopotential extending from pole to pole. It propagates westward along the equator at about 98 m s−1 ${\mathrm{s}}^{-1}$ and was first observed in surface pressure data ...

Tropical Cyclone Diurnal Cycle as Observed by TRMM

Monthly 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.

Degradation of Seasonally Frozen Ground in the Three–River Source Region and Its Correlation Impact Within Precipitation–Runoff Process

International Journal of Climatology, Volume 46, Issue 10, August 2026.
This study reveals how climate change alters the water cycle in the Three Rivers Source region by degrading its important ‘solid groundwater’ (seasonally frozen ground). We found that runoff response varies by watershed and the role of permafrost decreases sharply, making water supply more dependent on rainfall and becoming increasingly vulnerable ...

Mesonet‐Based Ground Validation of IMERG‐V07 and GSMaP‐V08 Over a Semi‐Arid Dryland Ecosystem in West Texas

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Climate change has caused highly uncertain precipitation regimes and associated hydrometeorological hazards over global drylands. Accurate precipitation measurements are vital for monitoring dryland ecohydrology. Satellite precipitation products (SPPs), including the Integrated Multi‐satellitE Retrievals for GPM (Global Precipitation ...

Estimating Uncertainty of PMW‐Based Convective Fraction Product

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Convective precipitation plays a crucial role in the Earth's hydrological cycle, vertical thermodynamic transport, and natural weather hazards. While satellite passive microwave (PMW) observations offer broad spatial coverage essential for global precipitation monitoring, uncertainties in PMW‐derived precipitation class (i.e., regime) remain ...

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

Atmosphere, 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 and Temporal Distribution of Groundwater Recharge in the West Bank Using Remote Sensing and GIS Techniques [PDF]

, 2010
Estimating groundwater recharge to aquifer systems is a very important element in assessing the water resources of the West Bank. Of particular interest is the sustainable yield of the aquifers.

Navigating Data Scarcity in Flood Risk Assessment

WIREs Water, Volume 13, Issue 4, July/August 2026.
This review conceptualizes “data scarcity” and analyses inconsistencies among commonly applied concepts of flood risk. It evaluates the interaction among hazard, exposure, and vulnerability assessment methods to navigate the identification of appropriate flood risk assessment approaches in data‐scarce areas.
