Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Subseasonal Tropical Convection Characteristics in the Energy Exascale Earth System Model Version 2
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract Accurate simulation of subseasonal tropical moist convection remains a key challenge for Earth system models. The difficulties stem from the reliance of cumulus cloud processes on model parameterizations and the need to represent the multiscale nature of interactions among clouds, radiation, moisture, circulation, and surface energy fluxes ...

On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract Deep tropical oceanic convection is a key component of the tropical atmosphere, with environmental moisture and vertical wind shear influencing its structure and intensity. However, attempts to generalize convection‐environment relationships across the broad‐scale tropics have produced inconsistent results, partly owing to limits of reanalysis,

An Adaptive Multipath Mitigation Filter for GNSS Applications
EURASIP Journal on Advances in Signal Processing, 2008 Global navigation satellite system (GNSS) is designed to serve both civilian and military applications. However, the GNSS performance suffers from several errors, such as ionosphere delay, troposphere delay, ephemeris error, and receiver noise and ...

Entrainment‐Based Framework for Understanding Extratropical Moist Heat Extremes
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract In summer, the atmosphere over extratropical continents is close to moist convective neutrality, whereby near‐surface moist static energy, MSEs ${\text{MSE}}_{s}$, is tightly constrained by free‐tropospheric saturation moist static energy, MSE500∗ ${\text{MSE}}_{500}^{\ast }$.

Empirical Modeling of Tropospheric Delays and Uncertainty
Abstract. Accurate modeling of troposphere delay is important for high-precision data analysis of space geodetic techniques, such as the Global Navigation Satellite System (GNSS). The empirical troposphere delay models provide zenith delays with an accuracy of 3 to 4 cm globally and do not rely on external meteorological input.

DNS (v1.0): an open-source ray-tracing tool for space geodetic techniques [PDF]
Geoscientific Model DevelopmentWe have developed an open-source ray-tracing tool for space geodetic techniques. The software uses the geometric optics approximation to calculate the signal travel time delay induced by the atmosphere between two given points.
