Maritime-Continental Contrasts in the Properties of Low-Level Clouds: A Case Study of the Summer of the 2003 Yamase, Japan, Cloud Event

open access: yesAdvances in Meteorology, 2014
Satellite data were used to investigate maritime-continental differences in the characteristics of the low-level cloud (the Yamase cloud) that covered northeast Japan during the summer of 2003. The features of the Yamase cloud were found to be almost the

Further development of adaptive parameter tuning in the numerical weather prediction models of Deutscher Wetterdienst

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The introduction of adaptive parameter tuning in the numerical weather prediction models of DWD in 2022 substantially improved the forecast quality of near‐surface variables like 2‐m temperature and 2‐m humidity. Since 2023, refinements and extensions, primarily affecting the surface evaporation and its diurnal cycle, have led to further advances ...

Comparison of model predicted cloud cover profiles with observations from ground and satellite

open access: yesMeteorologische Zeitschrift, 2000
Cloud cover profiles predicted by a large-scale atmospheric model are directly compared with observations for three meteorologically different situations, i. e. a frontal system, a case of deep convection, and a case with low-level stratus.

Analysis of a Sea Fog Episode at King George Island, Antarctica

open access: yesAtmosphere, 2019
In this study, a marine fog episode at King George Island off the Antarctic Peninsula from 26−30 January 2017 was investigated using surface observations, upper-air soundings, and re-analysis data as well as the air mass backward trajectory method.

Evolution of sea fog based on meteorological and oceanographic observations during FATIMA Yellow Sea campaign

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a conceptual framework linking sea‐water temperature Tw gradients to the formation and persistence of sea fog in the southeastern Yellow Sea. Over cold waters maintained by tidal mixing, downward latent heat flux enhances lower‐level stability and sustains persistent sea fog, whereas over warmer waters, upward fluxes and thermal ...

How weather got its words: a history of meteorological English – Part 2: the scientific age and beyond

open access: yesWeather, EarlyView.
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.

Elevation-dependent warming in Switzerland: Observed signals and dataset limitations

open access: yesJournal of the European Meteorological Society
Since the 1950s, Switzerland has experienced pronounced year-round warming, with the strongest increases occurring in summer and spring. The analysis of homogeneous, time-consistent, high-resolution monthly gridded near-surface temperature data reveals ...

Ice-nucleating particle depletion in the wintertime boundary layer in the pre-Alpine region during stratus cloud conditions [PDF]

open access: yesAtmospheric Chemistry and Physics
This study evaluates the regional variability of the number concentration of ice-nucleating particles (INPs) between the two pre-Alpine central-European sites of Eriswil, Switzerland, and Hohenpeißenberg, Germany, supported by INP measurements from ...
