Contribution of personal weather stations to the observation of deep-convection features near the ground [PDF]

Natural Hazards and Earth System Sciences, 2020
The lack of observations near the surface is often cited as a limiting factor in the observation and prediction of deep convection. Recently, networks of personal weather stations (PWSs) measuring pressure, temperature and humidity in near-real time have

Moonlight Duration and Intensity Favour Nocturnal Activity in a Diurnal Desert Bird

Ethology, Volume 132, Issue 9, Page 629-641, September 2026.
Accelerometer data show that Canarian houbara bustards increase nocturnal activity two‐ to fivefold when the moon is visible, with activity rising as moonlit duration and illumination increase. Both display and non‐display behaviours peaked around full moon, reaching up to half of peak daytime levels, with males increasing visual displays during ...

Unmothered at Work: Organizational Silence Around Reproductive Loss

Gender, Work &Organization, Volume 33, Issue 5, Page 1819-1842, September 2026.
ABSTRACT An identity transition refers to changes in self‐concept that can result from professional or personal shifts. Although organizations increasingly support institutionally legible and culturally normative nonwork transitions, others remain professionally stigmatized or culturally unspeakable.

Diurnal Pulses in Tropical Cyclones as Convectively Coupled Gravity Waves

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract This study uses convection‐permitting simulations to examine the vertical extent, propagation, and nighttime preference of diurnal pulses (DPs) in tropical cyclones (TCs). DPs are outward‐moving rings of cooler brightness temperatures near the storm center and may indicate TC intensification.

Analysis on a Squall Line and its Downburst over the Lower Reaches of Jinsha River

Gaoyuan qixiang
Squall lines often produce extremely disastrous gales and play a crucial role in the safety of hytropower stations.This article explores a squall line event over the lower reaches of Jinsha River on June 4， 2016， which brought 13-level wind at the canyon

Trends in thunderstorm days, lightning activity, squalls and the environmental factors in Hong Kong

Weather, Volume 81, Issue 8, Page 248-257, August 2026.
This study analyses trends in Hong Kong's convective weather using long‐term observer‐based and shorter‐term instrument‐based data. Annual thunderstorm days increased significantly by 1.9 days decade−1 in 1947–2024, notably in June–September, consistent with increasingly favourable warm‐season environments for thunderstorms.

Analysis of Dual-Polarimetric Radar Variables and Quantitative Precipitation Estimators for Landfall Typhoons and Squall Lines Based on Disdrometer Data in Southern China

Atmosphere, 2019
Typhoon rainstorms often cause disasters in southern China. Quantitative precipitation estimation (QPE) with the use of polarimetric radar can improve the accuracy of precipitation estimation and enhance typhoon defense ability.

Structural Properties and Reflectivity Patterns of Precipitation Systems Linked to Post‐Fire Debris Flows in California

Meteorological Applications, Volume 33, Issue 4, July/August 2026.
A radar‐based tracking algorithm analyzed Precipitation Systems (PS) over burned areas. At estimated debris flow timing, warmer‐season systems were smaller, slower, and more circular with localized high reflectivity (> 45 dBZ), while cooler‐season systems were larger, faster, and elongated with widespread moderate reflectivity (25–45 dBZ).

Microphysical Characteristics of a Squall Line Modulated by the Northeast China Cold Vortex Using Polarimetric Radar and Disdrometer Observations

Remote Sensing
Heavy precipitation in Northeast China is frequently modulated by the Northeast China Cold Vortex (NCCV), although the microphysical processes within squall lines under such conditions remain insufficiently understood. This study presents a comprehensive
