Resolution Dependence in a Global Atmospheric Simulation From km to 220 m Grid Spacing
Abstract We conducted a 220‐m mesh simulation over the global domain with realistic topography. This can be called a first “global large‐eddy simulation” (GLES) for deep convection. The resolution dependence across km‐ to sub‐km scales and sensitivity to turbulence schemes are investigated.

Cyclic Variation in Mean Duration of a Lightning Flash with the Thundercloud Activity [PDF]
72-75The variation in short term mean duration of a lightning flash was examined by means of the corresponding noise bursts, continuously during the occurrence of overhead storms. The cell structure of a thundercloud is reflected in the variation of mean

Politics of Narration: Mythical Discourse in Kie’s Son of the Thundercloud [PDF]
Writers are committed to the power of proof, reasoning and technical solutions to every possible problem faced by humanity. Convincing through proof and argument is construed to be the presentation of reality.

Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.

This paper summarises a coordinated field campaign in southern England in summer 2023 as part of the ParaChute programme, which studied atmospheric turbulence to improve weather and climate models. The field campaign used ground‐based instruments, aircraft and drones to observe turbulence and storms, creating datasets to develop better turbulence ...

The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.

Abstract Recent work has demonstrated that convection‐permitting models often produce a greater number of precipitating convective cells compared to radar observations. Congestus‐depth cells contribute most to the bias, which are colloquially termed “popcorn convection.” This study explores warm‐phase microphysical contributions to the bias using ...

Uncertainty of SYNOP Cloud Classifications by Human Observers
Operational cloud classification is subjective to some extent and should not be used without quality control for example, to train automatized methods. Inter‐observer agreement depends on the sky conditions, the nature of the observation (image‐based or on‐site), the framework under which it is conducted (sky snippets for gold standard atlases vs ...

A Unified Theory of Tropical Cumulonimbus Cloud Concentration and High Cloud Fraction
Abstract A variety of processes lead to tropical cumulonimbus clouds and anvils. Convection draws moist air into clouds from below, resupplying water lost to precipitation. Cloud condensate mixes vigorously, setting the cloud concentration near the cloud top where air detrains into surrounding clear‐sky regions.
