Moist orographic gravity wave drag parameterization reduces the bias of summer rainfall over the Tibetan Plateau

npj Climate and Atmospheric Science
Summer precipitation over the Tibetan Plateau (TP) significantly affects the regional and global climate. In this paper, the orographic gravity wave drag (OGWD) parameterization is revised by incorporating the moisture effect of saturated air into the ...

Recent progress in atmospheric modeling over the Andes – part I: review of atmospheric processes

Frontiers in Earth Science
The Andes is the longest mountain range in the world, stretching from tropical South America to austral Patagonia (12°N-55°S). Along with the climate differences associated with latitude, the Andean region also features contrasting slopes and elevations,

Numerical simulation and physical understanding of a locally initiated sea fog event over the eastern Yellow Sea with a transition of air–sea temperature difference

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Unexpected sea fog in the west coast of South Korea had a huge impact on the transportations in the Seoul–Incheon metropolitan area. We reproduced successfully the formation and evolution of a sea event with a transition of air–sea temperature difference using the Weather Research and Forecasting model.

Orography-Induced Gravity Wave Drag Parameterization in the Global WRF: Implementation and Sensitivity to Shortwave Radiation Schemes

Advances in Meteorology, 2010
This paper describes the implementation of the orographic gravity wave drag (GWDO) processes induced by subgrid-scale orography in the global version of the Weather Research and Forecasting (WRF) model. The sensitivity of the model simulated climatology

Unusual vertical oscillations of a radiosonde

Weather, EarlyView.
In summer 2023 in southern England, several unusual balloon launches were observed which descended for a few minutes before resuming ascent. This unusual vertical oscillation was repeated several times in a ‘roller‐coaster’‐like pattern. This article discusses the behaviour of the balloons.

Measuring Clear‐Air Vertical Motions From Space

AGU Advances
Measuring vertical velocity in the atmosphere has long been a challenge due to its small magnitude. Taking advantage of the modulation of free tropospheric relative humidity by vertical motions, we derive analytical relationships that allow us to ...

Extreme rainfall in southern China in April 2024 and its potential link to weather events across south Asia

Weather, EarlyView.
This study documents the unseasonal and prolonged heavy rain events which occurred in southern China during April 2024. In this series of extreme rainfall events, Guangdong province recorded extreme rainfall exceeding 6‐sigma of climatology, with eleven cities reporting record‐breaking rainfall.

Modelling representation errors of atmospheric CO₂ mixing ratios at a regional scale [PDF]

Atmospheric Chemistry and Physics, 2008
Inverse modelling of carbon sources and sinks requires an accurate quality estimate of the modelling framework to obtain a realistic estimate of the inferred fluxes and their uncertainties.

Characteristics of unique cap, Tsurushi and Hata clouds around Mount Fuji

Weather, EarlyView.
Distinct clouds, such as cap clouds, Tsurushi (a type of lenticular cloud) and Hata (banner cloud‐like clouds), frequently form around Mount Fuji, an isolated peak with a slightly elliptical conical shape. Here, we examine their characteristics and occurrence patterns.
