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 ...

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 ...

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 ...

Pengembangan Model Penduga Hujan Bulanan Menggunakan Data Satelit TRMM pada Tiga Pola Hujan di Indonesia

, 2013
Rainfall is one of the atmosphere parameters which is quite difficult to predict because of its very high variability on space and time. The recent development of rainfall observation technology nowadays is using rainfall satellite.

EVALUATION OF KuPR ALGORITHM IN MATCHUP CASES OF GPM AND TRMM

Journal of Japan Society of Civil Engineers, Ser. B1 (Hydraulic Engineering), 2015
GPM Core Observatory satellite has been in operation since February, 2014. Before the GPM operation started, TRMM had observed the rain rate in tropical regions. GPM's KuPR is a successor of TRMM/PR, and both have the same design [1]. However, differences have been confirmed in their estimates for the same rainfall. Therefore, we focus on the retrieval
