Asymmetry in the effect of North Atlantic sea surface temperature on the eddy‐driven jet

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Projections of climate over Europe and the Atlantic are uncertain due to the uncertainty surrounding future changes in North Atlantic sea surface temperatures (SSTs). Here, we demonstrate that warming in the North Atlantic Ocean is linked to a transition to a negative phase of the North Atlantic Oscillation, as well as to an equatorward displacement of

Multiscale numerical sensitivity simulations of a mesoscale gravity‐wave event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
High‐resolution WRF simulations of the February 14–15, 1992 STORM‐FEST event show that mesoscale gravity‐wave genesis occurs via geostrophic adjustment within an upper‐level unbalanced jet, while wave ducting governs maintenance. High‐resolution (1 km), improved physical parameterization, and targeted sensitivity simulations demonstrate that upstream ...

Modelling the global tropospheric ozone budget : exploring the variability in current models. [PDF]

, 2007
What are the largest uncertainties in modelling ozone in the troposphere, and how do they affect the calculated ozone budget? Published chemistry-transport model studies of tropospheric ozone differ significantly in their conclusions regarding the ...

Applicability Analysis of InSAR Tropospheric Delay Correction for Landslide Monitoring Considering Periodicity Characteristics—Case Study on Southwest Mountainous Region

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Tropospheric delay is a major limitation in interferometric synthetic aperture radar (InSAR) for measuring landslide deformation. It exhibits complex spatial–temporal variability, stochastic behavior, and is particularly difficult to model in 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 ...

THE EFFECT OF SEASONAL VARIATION ON GNSS ZENITH TROPOSPHERIC DELAY [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The Global Navigation Satellite System (GNSS) signal experiences delays caused by the atmosphere, leading to the lengthening of the geometric path of the ray, commonly referred to as tropospheric delay. This delay is a significant source of error in GNSS

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

Observed vertical distribution of tropospheric ozone during the Asian summertime monsoon [PDF]

, 2009
We characterize the horizontal and vertical distribution of tropospheric ozone measured by the Tropospheric Emission Spectrometer (TES) over North Africa, the Middle East, and Asia.

Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

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 ...
