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 ...

Multiscale controls on diurnal convection in the Maritime Continent: Insights from high‐resolution observations in Timika

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Across the Maritime Continent, diurnal rainfall variability is governed by interactions between regional‐scale atmospheric drivers and local land–sea breeze circulations. Afternoon convection is initiated over land by surface heating and propagates offshore, whereas morning rainfall develops over adjacent seas and moves inland under low‐level northerly

AGFS: a two-step real-time tropospheric delay model by integrating GNSS, ERA5, and GFS

Geo-spatial Information Science
Tropospheric delay is a major error source in high-precision positioning with global navigation satellite systems (GNSS). However, accurately modeling tropospheric delay remains challenging, particularly for real-time applications in regions with sparse ...

Coupled diabatic and frictional forcing of single‐layer vortical flow

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A single‐layer balanced model is used to illustrate how diabatic and frictional forcing of a primary balanced vortical flow can be coupled self‐consistently, including the advection of potential vorticity by the induced transverse circulation. The coupling is illustrated in the context of a developing tropical cyclone, in which boundary‐layer dynamics ...

Tropospheric ozone and El Niño–Southern Oscillation: Influence of atmospheric dynamics, biomass burning emissions, and future climate change [PDF]

, 2006
We investigate how El Niño Southern Oscillation (ENSO) influences tropospheric ozone and its precursors in a coupled climate-chemistry model. As shown in similar studies, tropospheric column ozone (TCO) decreases in the central and east Pacific and ...

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 ...

Spontaneous zonal symmetry breaking of tropical rain belt

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Precipitable‐water snapshots show how a sea surface temperature (SST)‐forced tropical rain belt can remain zonally elongated or spontaneously reorganize into a localized convective cluster. The simulations identify the SST conditions favoring this zonal convective self‐aggregation and relate the transition to changes in boundary‐layer circulation and ...
