Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.

Coupled observation‐operator approximations in outer‐loop coupling data assimilation
Quarterly Journal of the Royal Meteorological Society, EarlyView.We present a methodology for coupled variational data assimilation that allows the effect of coupled observation operators whilst maintaining separate minimisations across model components. This allows us to constrain the atmosphere, ocean, and sea‐ice components of our coupled model directly from satellite radiances. We illustrate the system in action

Evaluation and assimilation of Arctic Weather Satellite data in the AROME‐Arctic forecast system
Quarterly Journal of the Royal Meteorological Society, EarlyView.The Arctic Weather Satellite (AWS), launched in August 2024, is a prototype for the future EPS–Sterna constellation of small satellites carrying an innovative microwave sounder. We present the first assessment of AWS in the regional AROME‐Arctic numerical weather prediction system, covering post‐launch calibration results and the impact of AWS ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

LA TEMPERATURA DE LA SUPERFICIE DEL MAR PERUANO A PARTIR DE LAS IMÁGENES AVHRR / NOAA (2000 - 2003)
Revista de Investigación de Física, 2006 El objetivo de este trabajo es el análisis de la temperatura de la superficie del mar (TSM), estimado de los datos AVHRR / NOAA, cerca de la costa Peruana para su aplicación en la determinación de los frentes térmicos y en el estudio del Fenómeno El Niño.

Inter-Comparing SNPP and NOAA-20 CrIS Toward Measurement Consistency and Climate Data Records
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019 The cross-track infrared sounder (CrIS) is a Fourier transform spectrometer that provides hyperspectral soundings of the atmosphere over three wavelength ranges onboard on both Suomi National Polar-orbiting Partnership (SNPP) and NOAA-20 satellites. Quantifying the radiometric difference and creating a calibration link between SNPP and NOAA-20 CrIS are

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 ...
