An object-based analysis of cloud motion from sequences of METEOSAT satellite data
The need for wind and atmospheric dynamics data for weather modelling and forecasting is well founded. Current texture-based techniques for tracking clouds in sequences of satellite imagery are robust at generating global cloud motion winds, but their use as wind data makes many simplifying …

Long-term Changes in Synoptic-Scale Air Mass Persistence Across the United States
From a climate dynamics perspective, air mass persistence reflects variability in the dynamic nature of the atmosphere. In this study, a historical analysis of synoptic air mass persistence across the continental United States is presented to portray spatial and temporal variability and trends in …

The impact of Arctic amplification on the extratropical jets
… snow anomalies can suppress the October-November atmospheric response by interfering with the forcing of hemispheric (wave one) atmospheric dynamics. Intriguingly, the simulations do not force the persistent stratospheric response reported in similar experiments. This may be a consequence of …

An Analysis of the Differences Between Two Seasonal Saudi Arabian Dust Storms Using WRF-Chem
… research focused on understanding the difference atmospheric conditions between two major dust storms in Saudi Arabia. These two types of dust storms occur annually over Saudi Arabia with different seasons, sources, and atmospheric dynamics. We analyzed the Sharav case study in the spring season …
