Forecasting Weather Hazards for Transoceanic Flights


Remote, oceanic regions have severely limited data availability and therefore, have few, if any, high resolution weather products that indicate locations of convection. Convective hazards impact the safety, efficiency and economic viability of oceanic aircraft operations by producing turbulence, icing and lightning and by necessitating aircraft rerouting while in-flight, leading to higher fuel costs and delays.


The NASA-sponsored Oceanic Convection Diagnosis and Nowcasting product, is an intelligent system that generates 0-2 hour nowcasts of oceanic convective hazard regions. Geostationary satellite imagery are used to define the locations of deep convective clouds in oceanic regions, through the weighted combination of three independent algorithms.


This product is uplinked to airline cockpits via electronic flight bag systems to support safe and efficient flight operations and re-routing decisions.
