Quarterly Journal of the Royal Meteorological Society, EarlyView.In this study, a nocturnal extreme rainfall event was examined by using cloud‐permitting simulations with the Weather Research and Forecasting model. We proposed a mechanism for extreme short‐term rainfall formation under a beneficial dynamic pattern within a convective storm, and the mechanism is confirmed by a trajectory analysis of raindrops based ...

WRF-Model Data Assimilation Studies of Landfalling Atmospheric Rivers and Orographic Precipitation Over Northern California [PDF]
, 2014 In this study, data assimilation methods of 3-D variational analysis (3DVAR), observation nudging, and analysis (grid) nudging were evaluated in the Weather Research and Forecasting (WRF) model for a high-impact, multi-episode landfalling atmospheric ...

Analysis of the effect of the coastal discontinuity on near-surface flow [PDF]
Annales Geophysicae, 1998 Conditional sampling is used herein to examine the effect of fetch, stability, and surface roughness changes on wind speeds in the coastal zone. Using data from an offshore wind farm it is shown that at a distance of 1.2–1.7 km from the coast, up to a

Key Points in Air Pollution Meteorology
International Journal of Environmental Research and Public Health, 2020 Although emissions have a direct impact on air pollution, meteorological processes may influence inmission concentration, with the only way to control air pollution being through the rates emitted.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Ensemble Kalman filters implicitly linearize the observation operator, which causes the posterior to deviate from its linear approximation. We quantify the linearization error for visible and infrared radiances and conclude that the linear approximation should not be used for nonlinear observation types.

Mesoscale Meteorology and High Ozone in the Northeast United States
, 1998 This study examines the relationship between mesoscale meteorological conditions and high-ozone days in the northeastern United States. It is proposed that the leeside trough and the sea-breeze front are two mesoscale features that can be important on ...

Modelling the influence of soil moisture on the Turkana jet
Quarterly Journal of the Royal Meteorological Society, EarlyView.High‐resolution convection‐permitting experiments demonstrate that the Turkana jet is sensitive to soil moisture variations. When examining realistic dry and wet conditions, dry soils amplify a surface‐induced thermal low, which intensifies the along‐channel pressure gradient and strengthens the Turkana jet.

Investigate the impacts of assimilating satellite rainfall estimates on rainstorm forecast over southwest United States [PDF]
, 2004 Using the MM5-4DVAR system, a monsoon rainstorm case over southern Arizona (5-6 August 2002) was investigated for the influence of assimilating satellite rainfall estimates on precipitation forecasts.

A Bayesian Hydrometeor Classification Algorithm for C-Band Polarimetric Radar
Remote Sensing, 2019 A hydrometeor classification algorithm is developed by applying Bayes’ theorem to C-band polarimetric weather radar measurements. The Bayesian hydrometeor classification algorithm (BHCA) includes eight hydrometeor types: hail, rain, graupel, dry ...
