Impact of Indo-Pacific warm pool Hadley circulation on the seasonal forecast performance for summer precipitation over the western North Pacific

open access: yesEnvironmental Research Letters, 2020
The western North Pacific summer climate affects the densely populated East Asian countries, while seasonal forecasting over these regions remains challenging for dynamical models.

How Are Tornadic Supercell Soundings Significantly Different From Nearby Baseline Environments?

open access: yesGeophysical Research Letters, 2023
This study explores how tornadic supercell soundings significantly differ from the same‐location and same‐hour baseline environment soundings, sampled from the days prior to or following the event. Permutation testing is used to identify whether sounding‐

Modulations of local rainfall in northeast Australia associated with the Madden–Julian oscillation during austral summer

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The variation of rainfall and its diurnal cycle with the Madden–Julian oscillation over coastal regions of NE Australia exhibit both large‐scale and local‐scale influences. The widespread increased rainfall is driven by large‐scale forcings, while the local enhanced rainfall is likely affected by mesoscale coastal processes. The variation of convective

Microphysical Characteristics of Three Convective Events with Intense Rainfall Observed by Polarimetric Radar and Disdrometer in Eastern China

open access: yesRemote Sensing, 2019
Polarimetric radar and disdrometer observations obtained during the 2014 Observation, Prediction, and Analysis of Severe Convection of China (OPACC) field campaign are used in this study to investigate the microphysical characteristics of three primary ...

A simple parameterization of the short-wave aerosol optical properties for surface direct and diffuse irradiances assessment in a numerical weather model [PDF]

open access: yesGeoscientific Model Development, 2014
Broadband short-wave (SW) surface direct and diffuse irradiances are not typically within the set of output variables produced by numerical weather prediction (NWP) models. However, they are frequently requested for solar energy applications. In order to

Abrupt ending of the Madden–Julian Oscillation by convectively coupled Kelvin wave precipitation leaves a swath of flooding across Indonesia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
During July 2021 there were widespread reports of flooding across the equatorial Maritime Continent. This analysis reveals how interactions between a system of convectively coupled Kelvin waves (CCKWs) and diurnally phase‐locked westward‐propagating inertio‐gravity waves during an active Madden–Julian Oscillation (MJO) caused these extreme rainfall ...

Analysis of the effect of the coastal discontinuity on near-surface flow [PDF]

open access: yesAnnales 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

The Atmospheric Aerosol over Western Greece-Six Years of Aerosol Observations at the Navarino Environmental Observatory

open access: yesAtmosphere, 2021
The Eastern Mediterranean is a highly populated area with air quality problems. It is also where climate change is already noticed by higher temperatures and s changing precipitation pattern.

WRF-Model Data Assimilation Studies of Landfalling Atmospheric Rivers and Orographic Precipitation Over Northern California [PDF]

open access: yes, 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 ...

Uncovering the Drivers of the Equatorial Ocean Surface Winds

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Wind Patterns along the Equator. Shown are daily mean wind patterns along the equatorial basin indicated in Figure 1a as a meridional mean along −2∘$$ -{2}^{\circ } $$ to +2∘$$ +{2}^{\circ } $$ latitude, land cells included, from a 2‐year ICON simulation. Five ocean basins are shown in black. Yellow boxes outline the seasons and ocean basins, which are
