Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.

Object‐based deep learning for probabilistic convective‐core nowcasting from satellite data
Quarterly Journal of the Royal Meteorological Society, EarlyView.Convective cores detected from Meteosat infrared imagery are represented as compact physical objects to generate probabilistic nowcasts up to 6 h ahead. A spatio‐temporal transformer models interactions among evolving core populations and produces gridded probability forecasts across the western Sahel.

Do tropical waves play a role in modulating monsoon onset?
Environmental Research LettersThe onset of the Indian summer monsoon (ISM) marks a rapid transition from dry to wet conditions, yet the role of tropical equatorial waves in initiating this transition remains poorly understood.

A synoptic overview of the EUREC4A field campaign
Quarterly Journal of the Royal Meteorological Society, EarlyView.The figure shows a summary of the important synoptic features and associated cloud patterns during the EUREC4A field campaign, divided into four subjectively defined periods. In period 1 the fish cloud pattern was dominant, associated with a shear line, and there was an initial transport of dust from West Africa that reached Barbados in the third ...

Revisiting bare‐ground evaporation in a high‐resolution numerical weather prediction system
Quarterly Journal of the Royal Meteorological Society, EarlyView.An improved method is proposed to parameterize evaporation in numerical weather prediction models. The figure shows dew‐point temperature forecast error (standard deviation of forecast error and bias) versus lead time over the North Plains region during spring 2022 for three parameterizations: CTL, the α$$ \alpha $$ method of Jacquemin and Noilhan; IFS:

Characteristics of quasi‐stationary band‐shaped precipitation systems in Japan between 1989 and 2022
Quarterly Journal of the Royal Meteorological Society, EarlyView.(a) Annual occurrence frequency of QBPSs (green bars), five‐years moving average (blue line), and regression trend (red line) for 1989–2022. (b) Distribution of the geographical occurrence frequencies of QBPSs with a 5‐km resolution for 1989–2022. Quasi‐stationary band‐shaped precipitation systems (QBPSs) are a major cause of localized heavy rainfall ...

Remote Sensing in Ecology and Conservation, EarlyView.Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

CALIBRATION OF RADAR REMOTE SENSING SYSTEMS
The paper examines the issues of automatic internal calibration of airborne side-view radars for remote sensing of the Earth's surface such as "Cosmos-1500", "Sich-1", and aircraft systems - "Analog", "MARS". Estimates of measurement errors of quantitative values of the specific effective scattering area of probed surfaces and the results of radar ...

Remote Sensing in Ecology and Conservation, EarlyView.Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...
