Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

Mechanisms and Subseasonal Predictability of Unprecedented Multiple Tropical Cyclone Event in Autumn 2024

Geophysical Research Letters
In autumn 2024 (late October to mid‐November), an unprecedented multiple tropical cyclone (MTC) event occurred over the western North Pacific (WNP). Six storms formed within a month, surpassing the climatological mean by 4 standard deviations.

Comparison of Reanalysis Data Sets to Comprehend the Evolution of Tropical Cyclones Over North Indian Ocean

Earth and Space Science, 2020
Several reanalysis data sets are being used for understanding the role of environmental factors controlling tropical cyclones (TCs) evolution. Six reanalysis data sets, namely, European Center for Medium‐range Weather Forecast (ECMWF) ERA‐Interim (ERAI ...

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

The connection between North Atlantic storm track regimes and eastern Mediterranean cyclonic activity [PDF]

Weather and Climate Dynamics
A unique chain connects the flow over the North Atlantic and the development of cyclones within the Mediterranean basin. One typical mechanism includes several successive processes: upper-level flow perturbations upstream cause Rossby wave breaking (RWB)

Synoptic and large‐scale drivers of extreme precipitation events in the Himalayas

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Months associated with maximum frequency of extreme precipitation events (EPEs). 6102 extreme precipitation days (i.e., exceeding 99th percentile for daily precipitation) occurred across the Karakoram, Western Himalayas (WH), Central Himalayas (CH) and Eastern Himalayas (EH) during 1979 to 2023.

Improving heavy precipitation forecasts through phase‐aware nonlinear bias correction of all‐sky infrared radiances using cloud top temperature differences

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study proposes a phase‐aware bias correction framework for all‐sky infrared radiance assimilation. Cloud top temperature differences between observations and model background fields are used to identify cloud‐phase mismatch and cold‐cloud regimes.

Multi-Resolution Mapping of Aboveground Biomass and Change in Puerto Rico’s Forests with Remote Sensing and Machine Learning

Remote Sensing
Tropical forests are major contributors to the global carbon budget but are affected by disturbances such as hurricanes, which cause extensive yet spatially variable tree damage and mortality.

Association between mean zonal winds in the lower stratosphere and cyclonic storms

, 2011
The cyclonic storm frequency exhibits variations of different time scales. A study has been undertaken to examine the relation between the cyclonic storms and the equatorial lower stratospheric zonal wind oscillation (QBO).
