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

Quarterly 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

Quarterly 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

Quarterly 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 ...

ampycloud: an open-source algorithm to determine cloud base heights and sky coverage fractions from ceilometer data [PDF]

Atmospheric Measurement Techniques
Ceilometers are used routinely at aerodromes worldwide to derive the height and sky coverage fraction of cloud layers. This information, possibly combined with direct observations by human observers, contributes to the production of meteorological ...

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

Quarterly 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

THz spectroscopy of the atmosphere for climatology and meteorology applications [PDF]

SPIE Proceedings, 2017
We present a new satellite-based instrument concept that will enable global measurements of atmospheric temperature and humidity profiles with unprecedented resolution and accuracy, compared to currently planned missions. It will also provide global measurements of essential climate variables related to ice clouds that will better constrain global ...

Climatology of Surface Meteorology, Surface Fluxes, Cloud Fraction, and Radiative Forcing over the Southeast Pacific from Buoy Observations

, 2009
A 5-yr climatology of the meteorology, including boundary layer cloudiness, for the southeast Pacific region is presented using observations from a buoy located at 20°S, 85°W.

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

Quarterly 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 ...

Influence of Disdrometer Type on Weather Radar Algorithms from Measured DSD: Application to Italian Climatology

Atmosphere, 2018
Relations for retrieving precipitation and attenuation information from radar measurements play a key role in radar meteorology. The uncertainty in such relations highly affects the precipitation and attenuation estimates.

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

Quarterly 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 ...
