Subseasonal forecasts of the MJO and convectively coupled equatorial waves in ACCESS‐S2 and GraphCast: A multi‐year analysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ACCESS‐S2 performs better in predicting longer time‐scale and slower moving waves (MJO and equatorial Rossby waves), while GraphCast performs better in predicting shorter and faster moving waves (Kelvin and mixed Rossby–gravity waves). However, both models systematically underestimate precipitation amplitude across all wave types, especially over the ...

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 ...

Detection and global climatology of two types of spatio-temporal clustering of extratropical cyclones [PDF]

Weather and Climate Dynamics
The swift succession of multiple extratropical cyclones during a short period of time is often associated with weather extremes and characterised by a strong atmospheric jet and enhanced baroclinicity.

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.

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 ...

A cyclone phase space dedicated to extratropical cyclones

Weather and Climate Dynamics
Despite intensive research on midlatitude cyclones since the mid-twentieth century, open questions on their structure and development remain, like the question of their core temperature. Few studies have addressed what the proportion of cold-core and warm-core cyclones in midlatitudes is, but it is not clear yet if occluded cyclones are cold-core or ...

Assessment of subseasonal forecast skill of tropical–extratropical cloud bands over the four subtropical convergence zones

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the subseasonal predictive skill of tropical–extratropical cloud bands across four subtropical convergence zones in ECMWF reforecasts (2003–2022). Results show that, while exact daily predictions are limited to one week, accounting for temporal displacement improves forecast skill significantly, revealing a systematic early onset ...
