Impact of a subtropical high and a typhoon on a severe ozone pollution episode in the Pearl River Delta, China [PDF]

Atmospheric Chemistry and Physics, 2022
A record-breaking severe ozone (O3) pollution episode occurred in the Pearl River Delta (PRD) in early autumn 2019 when the PRD was under the influence of a Pacific subtropical high followed by Typhoon Mitag.

Systematic diurnal bias of the CMA-MESO model in southern China: Characteristics and correction

Frontiers in Earth Science, 2023
Model error is an important source of numerical weather prediction (NWP) errors. Among model errors, the systematic diurnal bias plays an important role in high-resolution numerical weather prediction models.

10–30‐day moist static energy evolutions related to the persistent heavy rainfall event in different stages of flood season over South China

Atmospheric Science Letters, 2023
In this study, the flood season in South China (SC) was divided into three stages: two first rainy seasons (FRSs) around the South China Sea summer monsoon onset and one second rainy season when Typhoon prevails, denoted as FRS1, FRS2, and SRS ...

Probabilistic wind speed forecasting in Hungary [PDF]

, 2013
Prediction of various weather quantities is mostly based on deterministic numerical weather forecasting models. Multiple runs of these models with different initial conditions result ensembles of forecasts which are applied for estimating the ...

A high-order conservative collocation scheme and its application to global shallow-water equations [PDF]

Geoscientific Model Development, 2015
In this paper, an efficient and conservative collocation method is proposed and used to develop a global shallow-water model. Being a nodal type high-order scheme, the present method solves the pointwise values of dependent variables as the unknowns ...

Estimating 1min rain rate distributions from numerical weather prediction [PDF]

, 2017
Internationally recognized prognostic models of rain fade on terrestrial and Earth-space EHF links rely fundamentally on distributions of one-minute rain rates. Currently, in Rec. ITU-R P.837-6, these distributions are generated using the Salonen Poiares-
