A radar‐based investigation of precipitation growth and decay in South Korea

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Within a Lagrangian framework, we quantitatively retrieved and assessed precipitation growth and decay using the South Korean radar network, focusing on spatial patterns over the unique geographical features, including complex topography and land–ocean boundaries. Our findings indicate that the precipitation growth and decay is significantly influenced

Kriging‐variance‐based multi‐member ensembles of radar–rain‐gauge precipitation estimates: Application in Switzerland

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We explore the variance of the radar–rain‐gauge combination kriging‐based system “CombiPrecip”, showing that it represents satisfactorily the radar–rain‐gauge precipitation uncertainty around the kriging expected value. We then present a method to generate ensembles out of it, which we find to be very similar in texture with the expected‐value image ...

Unbiased calculation, evaluation, and calibration of ensemble forecast anomalies

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Standard methods for calculating ensemble forecast anomalies result in statistical inconsistencies between forecast and verification anomalies, even if the underlying forecasts are perfectly reliable. An unbiased evaluation of anomaly‐based ensemble forecasts must account for differences in climatological sampling uncertainty between forecasts and ...

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

Analysis of changes in daily temperature and precipitation extreme in Jakarta on period of 1986-2014

open access: yesMATEC Web of Conferences, 2018
Climate change due to an increase in greenhouse gas concentrations has led to changes in extreme climate events. IPCC 2007 already predicted that average global temperatures would reach 0.74⁰ C in the last 100 years (1906-2005).

Risk Level Analysis of Lightning Strike with Simple Additive Weighting Method in Gowa Region

open access: yesJurnal Penelitian Fisika dan Aplikasinya, 2018
Gowa regency is one of the areas in the province of South Sulawesi that has a high potential of lightning events. This is influenced by its geographical location which is close to the mountainous area.

Improved time constant of a newly released air temperature sensor and its implications

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We set out laboratory response‐time evaluations for a recently released platinum resistance meteorological air temperature sensor from Campbell Scientific. The new sensor fully meets World Meteorological Organization and National Oceanic and Atmospheric Administration specifications for sub‐20 s 63% response time, even at airflow rates as low as 0.2 m ...

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 ...

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

Too‐stable North Atlantic climate system in CMIP6 experiments undermines precipitation projections in Europe

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An original method is applied to identify distinct periods of observed NAO spatial patterns, evaluating the ability of state‐of‐the‐art climate models to reproduce them. Their poor representation of this multidecadal variability increases uncertainty in winter precipitation projections for Europe and likely broad regions of the Northern Hemisphere ...
