Sofia Chabhi presents a marine forecast case study of Storm Ingrid.
The presentation examines the passage of Storm Ingrid (22–24 January 2026) and its severe impacts along the Moroccan coastline using satellite observations and remote sensing data. It analyzes the key oceanographic and meteorological features of the storm, highlighting how satellite imagery aids in monitoring extreme events and improving coastal vigilance.
José Manuel Gálvez discusses El Niño and the use of satellite tools to monitor its development.
The session aims to build an understanding of how El Niño modifies weather and climate in tropical regions and beyond, with a focus on satellite-based and numerical weather prediction tools. It covers the basic concepts and definitions of El Niño, its typical impacts, monitoring and classification, and applications of satellite observations for monitoring its evolution and impacts. It also examines the expected impacts of the current El Niño event, which has already exceeded the intensity of previous events observed since 1950.
Brian LaMarre discusses Hurricane Ian and the role of impact-based, probabilistic forecasts in supporting emergency management and public safety decisions.
Hurricane Ian made landfall as an intense Category 4 hurricane on September 28, 2022, on the southwest coast of Florida in the United States, claiming 156 lives in the U.S., including 66 direct fatalities in Florida. Drowning in storm surge waters was the primary cause of death. This presentation highlights how the National Weather Service worked proactively to prepare the public through engagement with core partners in media and emergency management before, during and after the storm. Public perception, based on lived experiences from past storms impacting the region, was a factor in the overall response. Additionally, there was a lack of understanding of how small changes in track can result in significant differences in impact based on the angle of approach of a hurricane moving toward Florida's north-south oriented coastline.
Gwenaël Le Bras presents OSI SAF sea surface temperature products, followed by Ad Stoffelen, who discusses tropical ocean surface vector winds using scatterometer observations.
EUMETSAT OSI SAF provides near-real-time retrieval of key parameters for marine meteorology in the tropical areas and around the globe. Here are presented the Sea Surface Temperature and Ocean Wind retrieval catalogues, illustrated with particular meteorological phenomena.
Hama Hamidou explains what dust storms are and their impacts, then discusses dust monitoring and forecasting.
Dust storms are one of the major high-impact weather phenomena that affect tropical arid and semi-arid areas, with important socio-economic impacts. Even though dust storms are generated in these regions, they can affect areas far beyond their source regions, depending on the weather systems present. In this presentation, the socio-economic impacts of dust storms, conceptual models for dust forecasting, and methods used for dust monitoring are presented.
Ivan Smiljanić discusses the differences between tropical and midlatitude storms using various satellite products.
Deep moist convection exhibits distinct characteristics across the tropics and mid-latitudes, reflecting differences in thermodynamic environments, vertical wind shear, and the mechanisms governing storm organisation. This talk compares the genesis, organisation, and dynamics of tropical and mid-latitude convective storms and discusses how these differences influence their monitoring and observation from space-based platforms.
Soukaina Boughanem talks about the process of forecasting and monitoring tropical convection over Morocco.
The presentation focuses on tropical convection over Morocco, with an emphasis on its forecasting and monitoring in relation to the northward extension of the ITCZ. The main atmospheric features and the use of numerical models, satellites, radar and observations for operational monitoring are also discussed.
Mirriam Mwende Musyoka talks about monitoring and forecasting convection in the tropics, with a focus on Central and East Africa.
Deep, moist convection is the principal producer of high-impact weather in the tropics and remains one of the most demanding forecast problems in operational forecasting in the tropics. This presentation reviews three interlinked themes. First, the typical seasonal patterns of tropical convection, i.e., the Zonal and meridional migration of the Intertropical Convergence Zone and the resulting monsoonal and bimodal rainfall regimes of equatorial regions, the afternoon-to-evening convective maximum, and the modulation of convective activity by intraseasonal variability such as the Madden–Julian Oscillation. Seasonal tropical cyclone activity in the Indian Ocean basin is also placed within the same framework. Secondly, it examines the major hazards from these convective developments and their impacts. Heavy rainfall and flash flooding, lightning, hail, damaging downdrafts and gust fronts, and visibility-reducing phenomena affect local populations through loss of life, displacement, damage to infrastructure and agriculture, and disruption of surface transport. Third, the presentation reviews the forecasting and nowcasting methods used operationally. The presentation will conclude by discussing how these tools are integrated into early warning services for high-impact weather scenarios.
Abhishek Lodh talks about how satellite observations, data assimilation and coupled numerical models improve forecasts of monsoons, tropical weather hazards and their impacts over the Indian subcontinent.
Accurate representation of initial conditions in NWP is critical for improving the prediction of high-impact tropical weather and monsoon systems over the Indian subcontinent. Operational developments at NCMRWF, including the assimilation of satellite-derived ASCAT soil moisture and INSAT-3D land surface temperature observations, demonstrate improved prediction of monsoon depressions, tropical cyclones, precipitation, and extreme temperatures, with enhanced forecast skill and extended predictive capability. These advances in land–atmosphere initialization strengthen operational early-warning information for weather-sensitive sectors and support better anticipation of impacts on communities, agriculture, infrastructure, and critical services.
Nanda Alfuadi talks about the multi-NWP model assessment regarding high-impact weather simulation.
The presentation examines the performance of four numerical weather prediction models (WRF assimilation, WRF non-assimilation, IFS, and GFS) during a heavy rainfall case in Jakarta, the capital city of Indonesia. Specifically, the discussion focuses on how effectively these models captured the high-impact weather signal starting three days before the event.
The NWC SAF MTG-I Lightning Imager Prototype Products Workshop introduces the upcoming NWC SAF GEO-LI software package, planned for release in 2027, and provides an overview of the new generation of products based on data from the MTG Lightning Imager.
The workshop combines technical presentations with practical examples, offering participants useful guidance on how to interpret and exploit LI-based products and their use in combination with other satellite products available in the NWC SAF EWC Viewer based on ADAGUC.
The recording of the event consists of three parts:
