Estimate of Ocean Wind Vectors Inside Tropical Cyclones From Polarimetric Radiometer

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Microwave polarimetry provides a distinctive opportunity to retrieve wind speed (WS) and wind direction (WD) inside tropical cyclones (TCs) due to the high atmospheric transmissivity through clouds and under rain conditions. A WS retrieval algorithm for WS above 20 m/s in TCs using brightness temperature at 6.8- and 10.7-GHz has been developed and a ...

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

International Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Assessment of the Exposure of Australia to Tropical Cyclones Through a Climatological Model for Cyclone Weather Extent

International Journal of Climatology, EarlyView.
Australia has different levels of exposure to tropical cyclones. Using historical records, this study investigates the spatial variability of tropical cyclone formation across the Southeast Indian–South Pacific basin, quantifies the exposure of different parts of Australia to tropical cyclone weather events, and examines decadal variability in cyclone ...
